In a separate heating system with natural circulation, some problems are found, which can be solved using circulating pump.

Forced circulation in the heating system - why it is needed

Installing the circulation pump in the heating system will evenly distribute heat across all radiators. It is uneven heating of the batteries that is the most common malfunction of water heating with natural circulation. The reasons may be somewhat, and they all lie in the wrong installation: the insufficient diameter of the pipes, the slopes, excessive length of the system, the air plugs in it are not met.

Many after finding out the cause of bad work of the heating system comes to convert it. And this means that it is necessary to change the pipes, if not all, then part, put the slopes, pierce the holes in the walls, to redo it. In a word: repair. Dust, smoke from welding and money, and considerable. Isn't there any other way out? There is, and it is cheaper, the work is performed faster, no dust. Of course, we are talking about circulating pump.

If the heating performs its functions normally, does it make sense to establish forced flow of the coolant? Undoubtedly, yes, and that is why:

1. 1. The inertia of the heating system is noticeably reduced. Circulation of water under coercion sharply reduces the time from the ignition of the boiler to warm even the most remote batteries.
2. 2. Align the temperature in all batteries. The coolant for natural circulation has time to cool before returning to the boiler, the near radiators warm up better than distant.
3. 3. Rises pressure in the system. Air traffic jams will not interfere with normal coolant circulation.

Meet the aggregate - how it works and works

The circulation apparatus causes warm water to move along a closed stake of heating. Its device is simple: a rotor with an impeller is installed on a stainless housing. They rotate during the operation of the electric motor, the impeller pulls the water inside and squeezes it into the system on the other side. Centrifugal force creates a pressure overcoming the resistance of the entire system.

Heating pumps produced two types: dry and wet. In a dry rotor, there is no contact with the coolant, their efficiency reaches 80%. It is very noise, therefore it takes a separate room with good sound insulation. Dry pumps require constant care. It is necessary to constantly remove dust from the room, otherwise it can be tightened inside the device, and it is depicted. Also dry pumps need to be constantly lubricated.

Despite the low efficiency of the wet circulation pump compared to dry - only 5% against 80% - in everyday life, they are much more used. This is due to lower cost, almost silent work, inconspicuous - care is practically not needed. The rotor and impeller are immersed in the coolant, which simultaneously lubricates rubbing parts. Care is reduced to the removal of air with simple unscrewing screw.

Choose the device - what to pay attention to

The correct operation of the pump with full capacity and due circulation in the system is provided by its selection by the necessary parameters. Increased power is not at all necessary for high-quality heating. Such an aggregate will produce increased noise, the cost is larger faster. To properly select the optimally suitable pump, a number of important indicators of the system are taken into account.

The calculation of the required power is made by formulas. Calculations are not very complex, but the practical experience of users made it possible to bring a simplified approach that justified itself. It takes into account only two indicators - the area of \u200b\u200bthe room and the maximum height of water lifting. We study the pump marking, which can look different on the plate differently. For example, one of the accepted labels looks like this: 25-40 / 180. The first number indicates the diameter of the connecting pipe, the last - the length of the kit, which is almost always equal to 180 mm, occasionally - 130 mm.

These indicators are important for installation, and for the choice of power, we pay attention to the second number. In this case, 40 - pressure, i.e. This device can raise water by 4 m. Another labeling method indicates H Max (M) - the maximum height of the coolant lifting in meters. The table below will help select the device forced supply of the coolant of the required power.

The table is indicative, more precisely to choose the device sellers of a specialized store, but to know the necessary parameters and be able to read the plate will not be superfluous.

Choose a place for the pump - on the feed or on the return

Theoretically, the coolant forced feeder is allowed to install anywhere closer to the boiler. It is able to withstand the maximum temperature of 110 °. But in fact, it is rarely resorted to this method, primarily from practical considerations. Of course, the water temperature in the boiler will not reach 110 °, but it can be close to it. Permanent elevated temperature will not add the pump of additional years of life.

But this applies, first of all, the systems of the private house with old boilers without a thermostat, especially solid fuel, where water can even boil. In modern boilers, the operating temperature is supported by the thermaller, it rarely exceeds 60 °. Installing the circulation pump for the submission in this case, practically does not shorten the life of its service. In addition, water coming out of the boiler is much cleaner of the one that comes through the return. Even a filter that is installed with the pump cannot guarantee full water purification.

Installing a coarse filter with a circulating pump is required. Holes in it are very small, they are capable of scoring the smallest particles of rust and dirt.

Most recommendations are still concerning the installation of the pump on the return highway. This is justified by the fact that in the upper part of the boiler when operating air is collected, it is pulled out by the pump, a vacuum is created. A high probability that the boiler will boil in this part. On the return water as if the pump is pressed into the boiler, the space with air is not created. The boiler always remains completely filled.

The figure shows a pump mounting scheme, where: 1 - heating appliance, 2 - automatic air valve, 3 - heat valve, 4 - heating battery, 5 - balancing valve, 6 - expansion tank, 7-haired crane, 8 - filter, 9 - The device forced circulation, 10 - pressure gauge, 11 - safety valve.

The inserting pump in the system is possible on the submission in the open type system, and on the return to the closed system with a membrane expansion tank, but it is possible to open system. The unit should be installed between the boiler and the expansion tank. Better simultaneously with the installation of the circulation pump, replace the usual expansion tank with a closed type membrane if the pump is installed on the return pump. Water in it does not contact with air, it remains clean, the pipes are not rust. The membrane tank is installed on the return on the circulation pump.

Mount the pump unit - sequence and important points

Each installation is supplied with an instruction that we carefully study to correctly perform. All liquid drain from the system, cut off part of the pipe in place, where the installation of the heating pump is assumed. In many cases, it is necessary to clean the old system in which dirt and rust accumulated. Through the drain crane, it can be bad because of the small opening section, so we use the place of the cut. To one side, connect the hose through which water is submitted. On the other hand, water flows, rinse until it goes clean.

On the pump plot, bypass bypass (bypass section). It is necessary in case of a breakdown of the pump or turn off the electricity. Then the coolant will go through the main highway, the crane in which we open manually. It is better to put instead of an ordinary ball crane automatic, which responds to a pressure change in the system. Bypass install two ball valves on both sides of the pump to overlap water to maintain or remove it if necessary. From above, bypass line by mounting the valve for air outlet.

After installing the bypass, I mount the pump. The pump shaft is installed in terms of the level horizontally, the more accurate, the better. If the position differs from the horizontal, only part of the rotor will be in the liquid, which will lead to a power drop and even breakage. Terminal box we have at the top. The pump housing along the axis is securely fixed by connecting nodes. Connection places are processed by a sealant, which will eliminate fluid flow, air drums and increase the performance of the device. When the pump is connected, we focus on the racks on the housing that indicate the direction of the fluid flow.

The heating system, calculated exclusively for forced circulation, will not be able to work with the disconnected electricity. For such cases, it is recommended to establish additional power sources.

Connecting electricity to equipment, we exclude the likelihood that moisture will fall into the terminal box. If the unit is located on the feed line, heats up strongly, then use heat-resistant wiring to connect. The cable should not touch the pipes, the pump housing. It is rated on any side, except for the bottom, rearring the plug. If the terminal box is located on the side, the cable will start the bottom. The device is necessarily ground.

After completing the installation work, fill in the coolant system. Remove air from the pump by tumping the central screw on the housing. When water appears, it will indicate the complete removal of air from the circulation pump. After that, run the device. On the case of most pumps there is a handle for adjusting the power. Checking work in all modes. Some models are equipped with an electronic regulator.

The heating device does not work - possible causes

Sometimes pumps break or work with insufficient performance. The most frequent reasons:

1. 1. Installed incorrectly. The horizontal of the shaft is not withstanding or it rotates not to the other side.
2. 2. Incorrectly driven from the power grid.
3. 3. Air gathered in the pump. It must be lifted through the central screw every time before launching.
4. 4. Water is poorly cleared. The filter is clogged or incorrectly installed - the labels indicate the direction of water movement.

Faults are easier to prevent if you are attentive when installed and start.

Due to failures in individual heating systems, private houses are often heated unevenly: some rooms are practically not heated, and in others it is too hot. To solve such a problem, the pumping installations of circulating type are used. To work with the greatest efficiency, it is necessary to correctly pick up and install the pump in your own heating system.

Reasons for installing additional equipment

Proportional heat distribution in a residential building can be achieved in two ways: increase the diameter of the heating system pipes or install the pump to the existing heating system.

The first method is effective, but requires dismantling and reinstalling all heating pipes in the house. The circulation pump will solve the problem of uniform heat supply is easier, cheaper and much faster.

Device and principle of operation

Circulation pumps are needed to create an additional water pressure in closed heating systems. Such a mechanism is built into a stainless hull on which a steel rotor or motor is attached.

An impeller is installed on the motor shaft, which is responsible for the forced circulation of the coolant.

Such equipment installed in the heating system creates additional pressure due to centrifugal force and increases water pressure.

Classification

The aggregates are two types. The first type is "dry" pumps. In the equipment of this type, the coolant and the rotor do not interact with each other. The working part of the rotor is isolated and removed from the engine with stainless steel sealing rings. When starting the ring come into motion, the thin water film seals the compounds due to different pressure in the system and in the environment.

The "dry" aggregate efficiency is about 80%. This equipment is very sensitive to water pollution in the system, and when small particles hit, quickly fails. The dry type pump is pretty noisy, so when it is installed, you should take care of the sound insulation of the room.

"Wet" pumps are distinguished by their design from "dry". The impeller is located directly in the coolant. The stator and the movable part of the mechanism are separated by a special glass that ensures engine waterproofing. "Wet" aggregates are cheaper and in operation, and in repair, work quieter than "dry".

The disadvantages of the "wet" type equipment include their low efficiency ⎯ only about 50%. This is associated with low sealing of the sleeve separating the stator and the coolant. Although even such performance is quite enough to heigh any private house.

Criterias of choice

The first important indicator when choosing a pump is its power. For high-quality heating, it is necessary to choose the device with the capacity that will be enough for heating. The pumps are more expensive and powerful for an ordinary residential building are not needed - they will still not be turned on at full load.

To calculate the optimal power, such parameters should be taken into account: the temperature of the coolant at the entrance and outlet, pressure, bandwidth, the performance of the heating boiler.

Counts

Coolant consumption can be equated to boiler power. For example, the heating unit with a capacity of 30 kW drives 30 liters of the coolant in 1 minute.

The most simple formula for calculating the optimal power of the pump looks in this way:
Q \u003d N / (T2 - T1),
In this formula N, the power of the boiler, and T2 and T1 is the difference in water temperature at the outlet of the tank and in the return.

The pressure is calculated on the basis of the wrong area of \u200b\u200bthe Square. According to generally accepted standards, 100m2 residential house requires a pump power of about 100 W.

Installation

The installation of the circulation pump is carried out as follows. First you need to carefully examine the instructions and the scheme for which it must be connected. The boiler and all heating equipment needs regular inspection and prevention, so you need to prepare an approach to the main nodes of the instruments in advance. Then you need to drain the entire coolant and clean the pipeline, after which you can decide on the installation site.

So, experts recommend setting this equipment near the boiler, on the pier of the returns. This position is explained by two reasons: the pump installed in this place will allow you to more evenly distribute the coolant in the boiler, which means it is to increase the efficiency of the entire heating system. In addition, on the return circulation pump will operate at a lower operating temperature, which increases its life.

On the selected sector, the sector is executed (bypass). This operation is necessary in order for the system to continue to circulate even when the power supply or breakage of the pumping equipment is turned off.

The diameter of the pipe of the bypass system should be less than the diameter of the main gas pipeline pipes. Only after the installation of the bypass is embarking on the installation of the unit.

The drawing of the installation technology of the circulation pump is presented on this scheme:

Installation features

It must be remembered that the shaft must be located horizontally. With incorrect installation, the circulation pump loses up to 30% of its performance, and for a short time may fail. Terminal box must be installed at the top of the system.

On both sides of the unit you need to embed the ball valves - they will need to be needed in the future, with regular technical inspections and planned repair work.

In the heating system, filters for water purification in pipelines from various solid particles should be provided. The latter when entering the pumping equipment leads to its serious breakdown.

The valve for the release of air from the heating system is mounted on top of the circuit tube. When installing the engine shaft, it is necessary to turn the box along the axis with a slight force. In an open heating system, an expansion tank must be installed.

To eliminate arbitrary change in the flow of water, in the field of entering the release of the circulation pump, shut-off valves are mounted. The connecting nodes must be processed by the "sealant", one hundred will increase the performance of the entire heating system.

To quickly and correctly install the pumping pump, you need selected connections and threads. To reduce the searches for all necessary parts, look at the plumbing stores a special device with already selected fasteners. After the process of mounting the pump installation is completed, the system is filled with water or other coolant.

Before running the system, you should open a central valve to remove air traffic jams - on full removal of air from the system will notice the water appeared.

About quantity and breakdowns

The number of circulation pumps required for heating the private house can be determined based on the entire length of the pipeline. If its length is about 80 m, then one is enough. Upon exceeding this length, you need to think about increasing the number of pumps in the system.

The causes of the failure of circulation pumps can be incorrect installation, an arbitrary arrangement of the cable liner and the terminal module, as well as non-compliance with the rules of operation of the heating boiler. To avoid faults, it is important not to ignore the procedures for regular air output and take care of the good cleaning of the system from mechanical particles.

But it should be remembered that all the breakdowns of the circulation pump must be corrected by specialists. Therefore, if faults have already appeared and detected, it is best to contact the repair service.

Hello. I recently installed the pump for heating in your home. It costs on the return near the stove, while the water move arrow is directed to the oven, it works, and the water is badly illuminated, is it correct? Maybe it was put on the other side ?? Help the advice.

Hello.

Did you install correctly?

Why are cold batteries?

There may be a lot of reasons for this, here are the most likely of them:

Pump installation scheme

A few words about the correct installation diagram of the pump to the existing heating system. You may find inconsistencies with how it is done with you. There are two options. The first, optimal: Pump is installed on the return on traverse (parallel) highway.

The parallel diagram is good because even when the pump is not working pump, the heating system functions as a gravitational, the coolant moves by a self-shot

Second: It is allowed to install a pump directly to the highway, without a bypass, but in this case the setting of the check valve is required. Such a scheme is worse than the complexity of the system's maintenance increases, and if necessary, remove the heating pump for the service to be turned off.

The circulation pump increases the efficiency of the autonomous heating system, allows 100% to use all heating contours.

Professional installation of the heating pump guarantees high performance, lowers the noise of work and reduces maintenance and repair costs. Installation of the device of special difficulties does not cause, but there are a number of nuances that are important to consider.

We will tell you how to choose a circulation nanos, we will help determine the optimal scheme of the equipment of the equipment into the system, and designate the installation requirements, as well as we give step-by-step instructions for installing the device.

Previously, circulating type pumps were used only in centralized heating systems, and for private house-building was the norm of the natural movement of the coolant caused by the temperature difference.

Now forced circulation is used everywhere due to the emergence of compact and inexpensive models designed to maintain heating networks of small houses and cottages.

With the advent of circulating pumps, the number of circuit solutions has expanded. It was possible to lay out extended highways of various difficulties, while the dependence on the slope has practically disappeared

Due to the increase in the movement speed of the coolant in the pipeline, the thermal energy is faster to the heating radiators, respectively, the premises are heating faster. The load on the boiler decreased, because the heating of the water began to be produced faster.

The need disappeared into the installation of bulky and uncomfortable pipelines of large diameter, the contours became easier to mask under the floor covering or shuffle into the walls.

There was an opportunity on any floor of a private house to mount the "Warm floor" system, which effectively acts only at a certain pressure in the network

The main disadvantage of pumps for heating systems is their dependence on electricity. If the power is supplied with interruptions or there is a risk of complete power outage for a period, the installation of a backup electric generator is needed or at least uninterrupted.

The remaining disadvantages concern the designs and functionality of devices of different types. For example, monoblock units and devices with a dry rotor are more noisy and require constant maintenance, and the pump with a wet rotor is demanding on the quality of the coolant and has a restriction on the pressure.

Criteria for competent equipment selection

All the efforts on the installation will be reduced to zero, if the equipment is incorrectly. In order not to be mistaken, it is necessary to first analyze all sides of a particular heating system and produce the necessary calculations.

The main varieties of pumps

By structural features, all devices are divided into 2 categories: with a wet and dry rotor.

Pumps "Wet" type. This option is suitable for private houses. The unit is compact, almost silent and has a modular structure convenient for maintenance and repair.

But, unfortunately, it does not differ in high performance - the maximum efficiency of modern models reaches 52-54%.

Circulating devices for heating networks can not be confused with similar devices for DHW. The heating pump does not need an anti-corrosion body of bronze or stainless steel and in additional protection against scale - respectively, and it is cheaper

Dry rotor pumps Productive, unpretentious to the quality of the coolant, are capable of working under high pressure and do not require a strict horizontal location on the pipe. However, they are more noisy, and their work is accompanied by vibration. Many models are installed on the foundation or metal support frame.

For mounting console, monoblock or "in-line" models are necessary. It is advisable to apply them when the consumption is required more than 100 m³ / h, that is, for servicing groups of cottages or apartment buildings.

A brief overview of the technical characteristics

When choosing a pump must be learned specifications and compare them with the requirements of the heating system.

These indicators are important as:

• podwhich covers the loss of hydraulics in the circuit;
• performance - water volume or feed for a certain time interval;
• operating temperature of the coolant, Max and Min - in modern models on average +2 ºС ... +110 ºС;
• power - Taking into account the hydraulic loss, the mechanical power prevails over the useful.

Structural parts are important, for example, input / output diameter of nozzles. For heating systems, the average parameters are 25 mm and 32 mm.

The number of electric pumps is selected, focusing on the length of the heating line. If the total length of the contours is up to 80 m, just one device is enough, if more - additional devices will be required.

An example of an aggregate for equipping the heating network of housing with an area of \u200b\u200b100 m² is the pump Grundfos Ups. With a pipe compound 32 mm, a capacity of 62 l / s and weighing 3.65 kg. The compact and low noise cast iron device is not heard and the thin partition, and its power is enough to transport the fluid to the 2nd floor.

Pumps with built-in electronics allow you to quickly translate equipment into a more convenient mode depending on the change of temperature or pressure on the network. Automatic devices are equipped with digital displays that provide maximum information on pumping: temperature, resistance, pressure, etc.

Additional information on the calculation and selection of a circulation pump for heating is presented in the articles:

Circulating pump installation requirements

There are a number of rules at the legislative level regulating the installation of the circulation pump to the heating system. Part of the rules is set out in SNiP 2.04.05 "Heating ...". For example, it says about priority in heating networks.

Almost all requirements are justified by the efficiency of the system in general and the circulation instrument in particular. For example, the shaft of the device with a wet rotor must be installed on the pipe strictly horizontally in the level so that inside the air traffic jams and the parts of the pump did not extend ahead of time.

The mandatory element of the system is an expansion tank compensating for changes in the volume of coolant when heated / cooling. Its place in the closed type system - on the return, in front of the circulation pump

The filter from dirt and abrasive particles is needed anyway even when mounting monolithic models. The cooler maker will bring much less damage to the details of the pump than the fluid with sand and weigon.

The mud set the plug down towards the movement of water to reduce resistance and facilitate system maintenance.

Some rules dictate manufacturers. For example, old models of certain brands were made exclusively on the return ratio, since they could not withstand high temperatures.

Now the pumps have purchased a more universal nature and can be put in any suitable place, but with the observance of power parameters.

Installation technology analysis

The installation process itself occurs quickly, so for fastening the case you need to fix two precipitated nuts. It is very convenient for further maintenance and repair work. But before installing, it is necessary to choose the right place of installation, otherwise the pump is either working with interruptions, or soon fails.

Network Pump Schemes

Choosing one of the schemes, it is necessary to take into account the type of heating system, the boiler model and the convenience of service.

Option 1. This is the most common solution: the pump is mounted on the "return", according to which the cooled coolant returns to the boiler. Warm water is not so aggressively affecting the details of the device, so it serves longer.

A good place for mounting - between the membrane tank and the heating boiler. This scheme is universal, it is equally good for the open and closed system, as well as for connecting instruments by collecting method (+)

Option 2.. This solution is relevant if the possibility of installing the pump on the "return" for some reason no reasons. Then it is fixed at the beginning of the contour, on the feed, but not near the boiler, and after.

Modern devices easily withstand high temperatures, but still there are specialists who reject such a scheme.

Cutting cranes are associated elements and are required for fast maintenance. To remove the circulation pump, you need to unscrew the cranes located on both sides of the case (+)

There is such an option of the heating network, as with an expansion tank installed at the highest circuit point.

If you install a circulation pump, then it will be possible to operate it in two modes: natural and forced. Natural circulation will be useful if there are interruptions with electricity.

So that you can switch the system from one mode to another, the circulation instrument is not installed on the pipe, but on the bypass - special tap. When the pump is turned on, the pipe is overlapped with a crane

The latter scheme only applies to networks with a solid fuel boiler. The submission pump is not installed due to the danger of the explosion. The fact is that it is impossible to quickly stop the heating process, as a result of which water boils.

Boiling water from the ferry falls inside the pump, it reduces the performance, cooled water in the circuit does not have time to come back into the boiler in the required quantity - and it is increasing even more. The result of overheating and the explosion becomes.

An additional element of the network becomes a thermo-mix valve. It serves to switch the circulation of the coolant from a small circle (with bypass) to large (+)

If you start the cooled water from the contour in the heated boiler, condensate will fall. So that this does not happen, the water first warms up in a small circuit to + 55 ° C, and then the thermostatic valve produces smooth switching to a large circuit.

As a result cold water Mixed with already preheated and "temperature shock" for the boiler does not occur.

How to make a pipeline strapping

The binding of the circulation pump is the equipment necessary for its proper functioning, as well as for the uninterrupted operation of the entire heating system.

First you need to finally decide how much pumps will be. For one simple circuit, one device is enough, but with a complex layout it is possible to install two or more.

If the house is planned to use the "Warm floor" system or set, then it is better to increase the number of devices to two. If two boilers are installed - solid fuel and electric - a separate pump is also required for each unit.

Correct (at the top) and incorrect (bottom) options for mounting the pump. If you choose an incorrect position and shift the axis of the rotor from the horizontal, you may occur or overheating (+)

As mentioned above, ball valves are mandatory elements. They are mounted along with the pump, and in the event of an emergency, it will take advantage of them.

We are also needed from brass or cast iron so that the coolant moves in one specified direction. It is mounted on the pipe immediately after the pump, along the movement of water.

A filter "Mudhouse" will be required to prevent solid particles from entering the instrument housing. Filters of fine cleaning in the contours of heating do not put. If clean water is needed, then it is pre-cleaned before the fill in the system.

There is a risk of entering the air network, so there is also a need for installation of the air valve. It can be turned on automatic mode, but there are manual models.

Using the fitting at a short distance from the pump, a pressure gauge is installed, sometimes two identical devices on both sides. With their help control the correct operation of the circulating unit

After mounting all devices, the pump is connected to the power supply. A big error is to use an ordinary socket without grounding. This safety infringement and at the time of the accident can cost life.

There are more reasonable power methods:

• through ;
• through a differential protection machine;
• by connecting to the automation of the boiler.

It is easier to use the automatic protection: the switch itself is 8 A, contacts, wires. But for practical use, a solution with a thermostat is very convenient.

Connection diagram with thermostat. When the temperature of the coolant in the network drops below a certain indicator, the thermostat works and turns off the power supply (+)

If the UPS installation is scheduled, you can organize a uninterruptible connection and a pump, and to the boiler at the same time.

Brief Installation Instructions

Completed option for mounting the pump on the bypass. This is due to two strong reasons: the possibility of operational dismantling or temporary disconnection of the device from the network, for example, when problems with electricity occurs.

Binding on Bypass: 1 - TN; 2 - "American women"; 3 - filter; 4 - shutdown cranes; 5 - the main pipe, "return" or feed; 6 - Crane, redirecting coolant in bypass

There are various modifications of finished pump nodes: under the welding or flange connection, with places to install cranes or valves, with a special area allotted under the pump.

But if the finished node will not be able to purchase or not be enough for its installation, you can independently organize a bypass strapping and fix all parts on the places allotted for them.

The following tools and materials are needed for work:

• set of horn or adjustable keys for assembly;
• pliers:
• linen thread or paak;
• unipak sealant.

The "American" nuts are usually supplied complete with the pump, but the cranes, adapters or slots will also have to prepare. ATTENTION should be given to a more reliable material manufacturing material and product diameter.

Procedure:

1. Build knots with cranes. Two will be located at the edges of the pump, the third will become part of the straight pipe. It is important to measure the "Furniture" plot to accurately breed a fragment with a crane.
2. Assembling pump loop. The tightening of the nuts must be moved to the finishing stage of the installation, but for now they only cost them. The device can be installed on any contour segment. Here the feed pipe is selected - not the best, but permissible option

   Grundfos circulation pump UPS

   

   

   

   Maintenance of the installed pump is carried out in operation. It is necessary to clean the filter more often and check the testimony of the pressure gauge.

   If values \u200b\u200bdo not match the norm, the device must be removed and adjusted. It is better to do this in a specialized workshop.

   Conclusions and useful video on the topic

   Theoretical knowledge is quickly absorbed accompanied by an interesting video that reveals the sequence and features of installation of instruments.

   Wilo pump video review - equipment and installation:

   Practice shows that advanced home improvement lovers cope with the installation of the circulating pump on their own.

   However, in case of difficulty, it is better to contact the specialists: only qualified masters know how to properly bind and install the heating pump, observing all the nuances of the selected scheme.

Private dwellings - today no longer. It ceased to be something exceptional - to build a good room, a good house on its plot. In the past, all sorts of Saharats and the hotel took place, but with them left and simplicity in the construction. For a good private home, you need to spend all communications - otherwise what kind of residential house is it? And with these moments there are problems at least from time to time. Below is the instruction on the installation of the pump in the heating system - this is quite an important point. Yes, what is there, in the system of heating a private house - this is one of the most important things!

Types of devices

After the state decided that in a private country house, you can also register, the owners of such buildings began to think about the possibility of living in their plot. Naturally, for this you need to think carefully and remake a little. It is not surprising because to turn a country house in a full-fledged cottage should be very tried.

Capital interior heating is one of the most necessary steps in the arrangement of a private house. So it is not surprising that the installation of the pump in the heating system is becoming increasingly frequent. This is happening only because whatever the autonomous part of thermal powder, for year-round work, it is necessary to install also and often cost only the pump if the heating is already there.

For consumers today there are two basic options - water and circulation elements. Talk about them below.

Water element

The home heating system is the most frequently required service. But you can not forget that there are much more powerful models that may well drop and apartment house. The last option, rather, exotic, not a rule. Therefore, it is considered precisely the heating of an ordinary private cottage.

Such pumps are not so popular as circulating, but they still have their customer audience. Installation in the heating system is an excellent solution if the rest of the system in a small house is already equipped.

Required for installation details

In addition to the water pump itself, the heating system, the heart of which he should become, includes several important details and devices, and ignore them will be fraught with negative consequences:

Fuel boiler.
. Hydraulic manifold.
. Hydraulic circuit (water supply system).
. Radiator.
. Mixing circuit (optional system element).
. Pressure sensors, temperature, water flow.
. Overheating protection system.
. Airlows.
. System of protection against overpressure.
. Air discharge valves.

It is not worth talking about which element here is more important here in such a procedure as the installation of a water pump in the heating system is not worth it. All of them are equally necessary, and therefore it is not recommended forget about something.

Circulating pumps

This is the second type of devices that have already been said. It should be noted that installing the pump in the heating system (especially circulating) is not a very complicated, but extremely useful procedure. Naturally, it is better to call masters who will cope with work faster. But, in principle, you can do it yourself. Especially if you prefer in advance about how to properly install the circulation pump in the heating system.

Advantages of circulating pumps

Neutility to heat supply systems - that is, all sorts of slopes, narrow sites, etc. will not affect the quality of heating. In addition, these parts are also suitable for the samotane heating scheme (i.e., where there is no own circulation).
. The fast acceleration of the system is, as it is clear from the title, provides a quick imprition of living spaces. That is, the installation of the pump in the heating system makes it more efficient.
. The reliability of work is simplicity in service and a fairly simple mechanism of work ensure the safe and very long exploitation of the device.
. The high efficiency of the efficiency - as already mentioned earlier, installing the pump in the heating system increases the efficiency of its operation. The circulation element raises efficiency to a maximum.

Types of circulation mechanisms

As in any other technique, there are several different types of details. So before you understand how to properly install a circulation pump in the heating system, it is better to find out exactly which circulation pump is needed. They are two types:

1. "Dry". Characterized by the fact that the rotor of the pump is not in contact with the coolant. They are equipped mainly by high-rise buildings and large rooms. Installing the pump to the home heating system, if it is referred to as "dry" type, fraught with some consequences, for example noise. It will create a twist of air, which will be due, in turn, noise that will interfere with living. That is why these pumps are rarely installed in private houses.
2. "Wet." This species is characterized by the fact that the rotor is immersed in water that pumped. It is these pumps most often installed in the system of heating of private houses and small residential premises.

Montaja technology

To facilitate the task or work to specialists who will conduct a procedure, it is best to purchase such pumps and equipment, where there are detachable threads in the configuration. If there is no one in the presence, then you will have to suffer, selecting various adapters. In addition, you will need to purchase a deep cleaning filter, as well as a check valve that will provide a normal pressure under pressure - and it does not depend on the type or view of the item being purchased, since the installation of the pump to the heating system simply requires all these parts.

Among other things, you will need some tools. For the punching of the pump, it will be necessary to stock different sizes - from twenty-two to thirty six. This is usually enough. Also necessary shock fittings and pipe cuts (the latter will play the role of bypass) with a diameter that is equal to the diameter of the riser.

Selecting the place of the insert

So that such a procedure, like installing the pump in the heating system, did not cause any difficulties, you need to take into account several points. First, consider the fact that the equipment of thermopodachi should be serviced. That is, the place must be sufficiently affordable for such procedures.

Other nuances

There are other features. For example, before the pumps were installed on the return - it was the opinion that chilled water, washing the working part of the element, extends its service life. Today there is no such problem, since the details of the mechanisms are resistant to any water temperature. So installing the pump in the heating system on the feed or on the return no longer matters.

In order to increase the pressure in the suction area, the item is best installed on the supply pipe area - it is possible at all next to the input point into the expansion tank system. Such a scheme will provide high temperature on a specified area of \u200b\u200bthe network. But for high efficiency, you need to buy an element, resistant to a strong step of hot water.

You yourself can make sure that the place of installation of the pump in the heating system should be strictly defined - otherwise it will be impossible to achieve good efficiency.

Device location scheme in pump connection

To install the pump correctly, a number of uncomplicated rules should be observed:

Ball cranes are installed on both sides. It is necessary that the pump can be dismantled, for example during repairs or replacement.
. A filter is crashed in front of the pump to the pipe - it is necessary to avoid entering large mechanical particles together with water.
. The top of the bypass is equipped with an air valve. Air traffic jams are not uncommon in such systems, and it is better to avoid them.
. The direction indicated by the arrow on the instrument must be observed - the movement of water should go strictly in this direction.
. "Wet" pumps are mounted horizontally. This device is protected from serious damage, if not the entire electric motor is immersed in water.
. Pump terminals are looking up.
. Threaded connections are equipped with gaskets and protected by sealants.
. Connect the pump only into the socket with grounding.

Installation sequence

In the case when you mount the pump in the current network, the coolant must be merged. The heating system with great "experience" is better to clean, we have driven water several times.
. The functional chain of fittings and pump is complied according to the installation rules.
. After installing and checking the system, it is filled with water.
. The last stage is the central screw turns, excess air is removed. When water is made from the holes, the element is ready for operation.

The last step is necessary for manual pumps - automatic models are coping with air independently. But if your unit is manual, then such a procedure must be repeated each time before turning on.
