Benefits
Using a pump of this type has many advantages:
- increasing the efficiency of the system;
- rapid heating of air in rooms and an increase in the heated area;
- alignment of temperature indicators in the pipeline;
- exclusion of airborne pipes;
- reduced fuel consumption;
- the ability to install heated towel rails, thermostats;
- the use of small diameter pipes;
- democratic cost of equipment.
A circulation pump is an opportunity to quickly improve the quality of heating a house without dismantling the entire system and spending big money.
Options
The installation of this equipment requires taking into account its parameters, the diameter of the pipes, the pressure force and temperature of the water, the density of the coolant.
H - designation of the pressure, the ability of the device to raise the liquid to a certain level. The parameter is measured in meters. Q is the liquid flow rate in the heating system for a certain period of time, calculated in m3. This value is equal to the boiler power parameter. The flow rate of the coolant depends on the diameter of the pipes.
The circulation equipment is not designed to raise water, therefore, when purchasing it, you need to pay attention to the Q parameter. If the boiler is not equipped with a pump, then the liquid flow rate must be calculated. A similar unit is already built into modern heating devices.
Additional pumping equipment is installed if the boiler is of an old modification, the heating design has been increased due to the expansion of the house area.
It makes no sense to buy a high-power unit: they will not use it in full force anyway. Moreover, such a device is too noisy. The length of the pipeline determines the capacity of the pumping equipment: for every 10 m of the pipeline, 0.6 m of pressure is required from it. A ring 100 m long will work efficiently and efficiently with a pump head of 6 m.
When buying pumping equipment, you need to remember that its power should be 10% more than the value that was calculated.
Additional pump on the car stove: how to choose and install
As a rule, on many budget cars, a regular stove does not warm up the interior quickly and efficiently. To a greater extent, this applies to popular VAZ models (2109, 2114, etc.), as well as some foreign cars.
In practice, one of the most effective and affordable ways is an additional pump for the stove. Next, we will consider what the specified stove pump is, how to choose an additional pump, and also how an additional pump is installed.
Additional pump: what you need to know
So, if initially the stove does not work well, although it is fully operational, and also if the car is often operated in severe frost conditions, the standard heating may not be enough even for middle-class cars.
In the case of VAZ or old foreign cars, the problem is solved by gluing the dashboard, modernizing the heating system, installing dense dampers, replacing the stove radiator, the stove motor itself with a more efficient one, etc.
However, if all these actions are not enough, then an additional pump for the stove may be the way out. In a nutshell, the auxiliary heater pump is an electric pump that drives the working fluid of the cooling system in a small circle even when the engine is not running.
This allows you to more actively warm up the interior when the engine is running or when the warm engine is turned off, but the driver and / or passengers are in the car (saving fuel and increasing comfort).
Also, an additional heater pump helps out even when the engine is idling without load (for example, when idle in a traffic jam) and cools down quickly. In such conditions, a regular stove usually blows not hot, but only warm air.
By the way, the same thing happens when driving on a highway at high speed in the cold season, when oncoming air flows intensively cool the engine compartment, as well as the coolant in the cooling radiator, etc. In turn, the additional pump for the heater makes the coolant circulate more actively and give off more heat.
Another advantage is the ease of installation, which means minimal intervention and changes to the factory design. Simply put, an additional pump is cut in so that the coolant circulates in a small circle.
A simple connection of the pump to the vehicle's electrical network is also realized. Usually all necessary fasteners, adapters, connectors, etc. are included with the pump.
Which pump for the stove is better to choose
First of all, the pump itself is the most important element. In the market, the GAZelle stove pump is in the greatest demand, since it is cheap and affordable. However, the solution has several serious drawbacks (noise during operation, high power consumption, average resource).
It turns out, even taking into account the fact that the Gazelle heater pump is inexpensive, for a passenger car, experts recommend considering an additional BOSCH pump.
Depending on which pump was chosen and on which machine it is installed, it may be necessary to purchase a 4-contact relay, a 3-contact toggle switch, as well as wires, terminals, corrugations, hoses and clamps, bolts, fasteners and even sealants.
For example, a sealant is necessary if a Gazelle stove pump is installed on the VAZ 2114. We also add that the pump from the GAZelle needs to be additionally upgraded, while the additional BOSH pump is faster and easier to install.
Installing an additional pump on the stove
When all the nuances have been taken into account and a suitable electric pump has been purchased, you will also often need to buy the additional elements and fasteners discussed above. Only after assembling a complete installation kit, you can proceed to installation. Let's take a look at a simple installation of a BOSCH pump in general terms.
As for the pump from the GAZelle, the general installation principle is similar, but the pump itself needs to be disassembled and modified. In short, it is recommended to disassemble the pump and seal it with a sealant. If this is not done, the antifreeze will start flowing through the pump very quickly.More precisely, you need to coat the area where the impeller and the sealing rubber ring are located.
Also, the standard self-tapping screws that are used in the design of this pump, it is optimal to immediately change and install screws of better quality. After processing with a sealant and assembling the pump, it should not be immediately put on the car. The point is that the sealants must dry, which will take at least 48 hours.
- If we consider the control of the pump, it is also necessary to display the button separately. Usually it is taken out on a dashboard, put instead of plugs, etc. Power to the stove pump button can be directly taken from the battery. The main thing is to install a fuse, as well as a relay.
- You also need to correctly lay the wiring, all wires must be shrink-wrapped and securely fastened. After installation, the driver is able to turn the pump on and off at his own discretion.
Types of pumps
For the energy carrier to circulate efficiently, dry and wet pumps are used.
Dry
In equipment of the first type, the contact of the rotor with the coolant is not provided. The seal used in such a device hermetically separates the pump itself from the motor. The efficiency of this equipment is 80%, so it is advisable to use it when constantly pumping a large amount of liquid.
The area of application of dry pumps is shopping centers, factories, factories. In private houses, such structures are not used due to the high level of noise generation.
Wet
The rotor of wet pumps is in the coolant, which they are pumping. Water cools down the engine. The stator included in the structure serves for the supply of electricity. Pumps with a "wet" rotor have a lot of advantages: long service life, rare maintenance, low noise generation, small size, ease of block replacement.
Cons - low efficiency (about 30-50%), limited scope (private houses and city apartments), inability to use pumps for drinking water and for everything related to food.
Low loss header
If there is a need to install an additional pump, then another device, a hydraulic separator, must be included in such a heating system. In the list of terms used, the hydraulic separator can also be called anuloid or hydraulic arrow.
Where to put
In the autonomous heating system of a private house, it is recommended to install wet rotor circulation pumps that rotate without the use of special lubricants. The coolant here acts as a coolant and a lubricating element. When installing such a device, the following rules must be observed:
- The pump shaft must be in a horizontal position in relation to the floor surface;
- The movement of the water flow in the system must coincide with the direction of the arrow on the device;
- To prevent liquid from entering the pump terminals, the box should be installed on top or side of the equipment.
Correct installation of an additional pump in the home heating system
According to some users, it is better to install the pump in the return pipe. Here, the temperature of the coolant is minimal, which will increase the life of the device, but not all experts agree with this statement. The fact is that the pump is designed for operation in a coolant environment, the temperature of which can reach 110 degrees.
Installation technology
Installation of a circulation unit is a process that requires adherence to a certain sequence of work.
Training
Experts recommend purchasing a pump with split-type threads. If they are not there, then you need to buy these parts additionally. You will also need a deep filter.
Before installation, a check valve is prepared: this normalizes the operation of the heating system.
You will also need special keys, fittings, a pipe, small in size, with a diameter equal to the diameter of the riser.
A place
Modern circulating pumps can be installed both on the water supply pipe and on the return pipe.
Installation carried out on a bypass (a jumper installed between the direct and return wiring of the heating radiator, a pipe section) requires a preliminary check of the device's ability to withstand a strong pressure of hot water.
In houses equipped with a "warm floor" system, the injection device is installed at the place where hot water is supplied: this will exclude the airiness of the pipeline.
If there is a diaphragm tank, the bypass with the pump is placed on the return pipeline, closer to the expansion tank.
Installation
The heating system can be made of metal or eco-plastic. There is no difference for the installation of pumping equipment. It is inserted by tracing. If the pipeline is made of metal, then you can purchase a ready-made structure for bypassing the main highway.
First, you need to drain the water, clean the heating structure, rinsing it several times.
Connection features
When connected to the mains in systems with natural circulation, an automatic fuse is used (with a flag), with its help you can disconnect. It must be installed at a distance of at least 0.5 m from the boiler.
The pumping device in structures with forced circulation begins to function when the thermal relay is turned on. In order for the additional and built-in units to work simultaneously, the first must also be connected to a relay or to the second in a parallel way.
In electric boilers, the circulation equipment is connected directly to the boiler, which makes it possible for it to operate only at the moment when the water is heated.
A cleaning filter is usually installed in front of the pump.
A special valve (automatic or manual) installed at the top of the bypass will make it possible to remove the air accumulated in the heating system.
Installation of wet-type equipment is carried out horizontally. Its terminals should be at the top.
All threads of the heating system must have gaskets pre-treated with a sealant. To use pumping equipment safely, you must use a grounded outlet.
Installation of a pumping unit in a heating system requires taking into account all the nuances. Only then will homeowners forget about problems with heat distribution and air pockets in the pipeline.
One of the main types of equipment that is used in the heating system of a private house is a circulation pump. This device allows you to more efficiently transport the coolant through the system, which will contribute to uniform heating of the premises. In our article, we will describe why an additional pump is needed in the home heating system, we will get acquainted with the diagram and the place of its installation, its use in the Heated floor system.
Preparing to install a heating pump
Before installing the pump, you need to buy it. Much depends on the right choice.
Pumping equipment can be of different types.
There are many different models on the market from different manufacturers. It is necessary to choose a pump for heating, the characteristics of which correspond to the characteristics of the room, its area, the number of windows, external walls, etc. Better to give preference to a more well-known manufacturer. Too cheap units should not be bought in view of the high probability of acquiring a fake. And when operating such equipment, many problems can arise.
To simplify the process of installing a pump for heating, it is better to choose a pumping device with split threads. Otherwise, you will need to select adapters. And not every user will like it.
From additional equipment and tools for work you will need:
Is it necessary, and in what cases
Many owners of suburban real estate, and especially two-story houses, are interested in installing an additional circulation pump in the heating system. They come to this conclusion after uneven heating of the radiators in the premises, provided that the boiler has sufficient power. If the temperature difference between the boiler and the coolant in the pipelines exceeds 20 degrees, then it will be necessary to remove air locks or set the existing pump at an increased speed.
Installation of additional pumping equipment is necessary in the following cases:
- When adding an additional circuit to the heating system, and especially when the length of the pipes exceeds 80 meters;
- For uniform movement of the coolant in pipelines.
An additional pump in the heating system may not be needed if it is balanced using balancing and adjusting valves, so before purchasing additional equipment, bleed the air from the batteries and add water to the system. If everything works fine, then there is no point in installing an additional pump.

“Fucking basin. "
Hello everyone! My name is Mikhail, now I'll tell you a story about how I managed to exchange a dvenashka for a 2010 Camry. It all started with the fact that I was wildly annoyed by the breakdowns of the two, like nothing serious broke, but on little things, damn it, so many things that really started to enrage. Here the idea was born that it was time to change the car to a foreign car. The choice fell on the tayet Camry of the tenths.
Yes, morally I matured, but financially I could not pull it. I must say right away that I am against loans and taking a car, especially not a new one, is unreasonable on credit. My salary is 24k a month, so it's almost impossible for me to collect 600-700 thousand. I started looking for various ways to make money on the Internet. You have no idea how many divorce there are, which you have not tried: sports betting, and network marketing, and even a casino volcano, in which it successfully lost about 10 thousand ((The only direction in which it seemed to me that you can make money is currency trading on the stock exchange, it is called forex. But when I began to delve into, I realized that it is very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it is much easier to understand. I began to read forums, study trading strategies. I tried it on a demo account, then I started a real account. To be honest, I didn’t manage to make money right away, until I understood the whole mechanics of options, I lost about 3000 rubles, but as it turned out it was a precious experience. Now I earn 5-7 thousand rubles a day. buy after half a year, but as for me this is a good result, and it's not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family.

The choice of an additional pump for the VAZ 2110
Most often, at VAZ, an electric pump from a Gazelle is chosen as an additional pump, but you can use a pump from other manufacturers (for example, Bosch).
Gazelle pump is a conventional centrifugal pump. The flow is thrown by the blades from the center to the periphery, due to which there is a rarefaction at the inlet, and, accordingly, the force of pumping the liquid. She does not know how to pump air (the gaps between the impeller and the casing are large).
Gazelle pumps are also different (for example, the old model and the new one).The new pump, unlike the old one, vibrates much less and generally makes itself felt less in an unpleasant sense.
According to unverified data, but the source is as knowledgeable as possible: They began to put a new seal, bourgeois, on the pumps from Elar, in order to eliminate leaks. Over the past season, there were no complaints about the course. Of course, this will not affect the noise level. They also increased the flow area of the nozzles on their pumps, which gave an increase in performance.
To the left is "Elara", to the right of "Advers". Both are for 20mm hose.
As the saying goes, which pump you choose is the way it will work. 
The main problem that you may have with an additional pump is its leakage. If you choose a quality pump and install it correctly, then you reduce the likelihood of pump breakdown to a minimum.
How to install an additional electric pump from a Gazelle car in a VAZ 2110?
Would need:
- Gazelle pump (Gazelle pump price 500-1000r)
- Relay (Take a relay with normally open contacts (2105,2108-starter, ignition relay). Jumper contacts 30 and 86)
- Reinforced hose piece
- Antifreeze (2 liters)
- Clamps ("norm" average 5 pieces)
- About an hour
Before starting work, you need to wait a little so that the antifreeze in the car cools down. We drain the antifreeze from the block into a clean container (then pour it back) or into a dirty one to fill in a new antifreeze.
