What is the best way to put the pump on the heating. We design additional heating systems with the installation of pumps and radiators
Forced circulation of the coolant through the pipes allows you to save fuel or increase the efficiency of the boiler without increasing the cost of heating your home. But for uniform heating of the area in two-story cottages, you may need to install additional pump into the heating system. In addition to the circulation pump, the heat supply circuit is supplemented by a hydraulic distributor. It allows you to create several circuits with independent temperature control of the radiators.
We recommend placing a signal foil or cable above the hose before filling. Is it possible to drill a geothermal well in rock? Yes, of course, in the rock it sounds very good, because it does not sprinkle, and there is no need to climb it. A high quality drilling rig can drill 90-120m holes per day in the rock. Complex drilling is located in places with sands, gravels or areas where soft and hard subsurface layers alternate.
There are huge differences in the quality and price of air source heat pumps. One of the reasons is also the soundproofing solution. The better the sound insulation, the more expensive the pump. Noise reduction is mainly possible in three ways. Expansion of the evaporator, which reduces the sheet metal cover installation flow rate, resulting in noise on the ground using high quality fans. For this reason, a cheap heat pump can never be quiet, although many suppliers talk about their products.
Benefits of installing an additional circulation pump
The installation of two circulation pumps helps to obtain a number of advantages. They appear depending on the specific situation, the design of the heated building and a list of other factors such as the quality of insulation of different rooms.
Key points that attract owners of private cottages:
Want to see the selected pump in the control building. Another high quality heat pump of similar capacity has an acoustic pressure level of 1 meter from the unit of 50 dB. How many quality pumps would you have to stand next to each other to sound like a cheap pump? Although it sounds incredible, the correct answer is 20 pieces.
Always look up the sound pressure level in the technical sheets. The heat pump consists of an outdoor unit and an indoor unit, most often in a wall-mounted version. Like air conditioners. Advantages of air-to-air heat pumps. Selected indoor units also have an air purifier including an air ionizer. Suitable for heating cottages, cottages, winter gardens, workshops, restaurants as a fast and cheap heating system.
- Low purchase price.
- Easy and fast assembly.
- In cooling mode, it is used as an air conditioner in summer.
- You can use the dry function.
- the heated area is noticeably expanding: any pump has a limitation on the creation of coolant pressure, two units will operate in "light" mode;
- uneven heating of the premises is excluded or an advantage is created for the bathroom, nursery (due to a separate circuit);
- reducing the noise level from the operation of pumps: when one pump is in operation, with a large area of \u200b\u200bhousing, it has to be turned on at full capacity, while several units will cope with the task at low speed.
The use of a second pump should be foreseen at the heating design stage and the location should be calculated in advance. But it is possible to introduce the block later, an experienced master will not have any difficulties with this.
Heat is transferred to the air without letting through the radiant component, as with heating radiators. To eliminate these shortcomings, it is necessary to choose an air-to-water heat pump.
- You must install an indoor unit in every room.
- Hot water cannot be heated.
Advantages of air source heat pumps
In summer, you will also use cooling to install the cooling model and fan coil units. The operation of the heat pump is energy-saving, which allows you to save up to 80% of the cost of heating the heating and hot water. The purchase price of a heat pump is refundable even without subsidies for up to 3-8 years. After an expert installation of a heat pump, you will receive a favorable electricity tariff from your electricity distributor for your entire home. By purchasing a heat pump, you will be less concerned about further energy costs. The operation of a heat pump is a step towards ecology, since only a small consumption of electricity saves the environment. Compared to traditional heating with classical solid fuel with boiler feed, heat pump operation is clean, comfortable and unattended. The heat pump can also be operated remotely via the Internet or mobile phone.
- Suitable for installation in both new buildings and renovations.
- Cheap boiler heating.
- Dry function in cooling mode.
Features of installing two circulation pumps in the heating system
When installing an additional pump, certain rules must be strictly observed. The choice of the connection point, the list of fittings and taps should be entrusted to an experienced specialist. Thanks to this approach, the procedure will take a minimum of time.
Water heating is a fairly common option for arranging private houses. Firstly, this type of heating is economically beneficial both in terms of installation and operation, and secondly, its installation is a fairly simple and labor-intensive process. One of the main components of the thermal circuit is the pump for the heating boiler, which creates artificial pressure in the system, "forcing" the coolant to constantly circulate around the circuit. And how the pump for the boiler works, you will learn from this article.
The efficiency of individual systems is determined by the heating factor, which expresses the ratio between the energy supplied to the heating system and the electricity received from the heating system. net. We do not heat the entire tank and the system works even when equithermal control is performed. A heat pump is not only a question for us heating season, but also an element of lowering the cost of housing throughout the year.
Design - Depending on the expected heat output, determine the size of the heat pump. Based on local conditions, we recommend the type of evaporator. We will prepare the contract and set the price of the contract. Many people who want to bring energy saving solutions to their home are looking for savings from their heating and hot water bills. Below you will find 3 questions that especially deserve to be answered before making a decision.
Purpose of centrifugal pumps
Heating systems with natural circulation of the coolant were popular several decades ago. Today, such structures are quite rare. The principle of operation is simple: due to the difference in density between hot and cold water the movement of fluid through the highway and radiators. In addition, to improve the circulation of water along the circuit, a slight slope of the pipeline is required.
The pipes connecting the lower manifold to the compressor to which the glycol solution flows will be under the foundation where the propulsion system will be in the future. It will not damage the thermal insulation or damp building. Of course, the customer decides to purchase the pump a little later. But then we make a connection under the footbridge, and we just break a small part of the flooded floor. The shreds are later restored according to the art of building. And how do you insert pipes into a building?
To the building, it is completely unnecessary to get wet. There is also a chilled foundation. The foam that an unreliable team often "protects" a puncture is usually not suitable for ground contact. After a while, it will disappear, and the place where the pipes are introduced into the house will remain unprotected. Such actions, in my opinion, are unacceptable. Installation cannot damage the building! Piping under the foundation gives you a guarantee.
However, such systems are not ideal and even minor errors during installation can lead to a decrease in the efficiency of the heating unit as a whole. So, in the last few years, people have increasingly begun to equip heating mains with centrifugal hydraulic pumps, which easily eliminate all the shortcomings of blocks with the natural movement of hot water through the pipeline.
Even good and efficient equipment will not cope with the executive bunker and illiteracy in the field computer science. The depth of the wells and their number depend on the power of the pump and the geological conditions that exist in the area. Works should be based on the so-called. geological project. Life shows, however, that real conditions sometimes diverge from expectations.
The wells are drilled with a drill rim - the drill bit rinses the dredged material under pressure. Water with the addition of polymer mixtures also flows through the walls of the hole and heals it for some time. This facilitates the lowering of the pipes - probes. Theoretically, everything seems quite simple, but in practice it often turns out that you have to deal with various obstacles: large stones, underwater streams, etc. after the probes have been drained, the pipes are fed into the lower manifold.
Among the main advantages of an additional pump, it is worth highlighting:
- there is no need to slope the pipes in order to improve the movement of the coolant along the circuit;
- no restrictions on consumables, namely on the diametrical size of pipes (with natural circulation large cross-section pipes are recommended to increase bandwidth);
- in the heat main due to temperature differences are not created air locks that prevent the full circulation of the fluid;
- ensuring uniform heating of the room, since hot water moves at a certain, always the same speed;
- due to the high speed of movement of the coolant, the temperature difference at the outlet and inlet to the boiler is minimal, which does not require big expenses fuel to warm it up.
In addition, stable temperature regime allows not only to save on thermal resources, but also significantly extends the operating life of the heating boiler.
We use the so-called windings. The loops coming out of the collector are no more than 90 meters away. Only then will their performance be optimal. If the room is large, and one loop is not enough to provide proper heating, then another. Each of them has a separate exit and entrance to the splitter.
The lengthening of the loop leads to a deterioration in energy consumption, and consequently, the heating efficiency decreases. After laying all the chains, the screeds close the pipes. Why start with a heat pump? In a house with an area of up to 200 m², a heat pump has a chance of being transformed in less than 10 years!

Types of pumping units
So, why do we need a circulation pump, we have already figured it out. And the very name of the device answers this question. Let's go further. The correct functioning of this unit is ensured by a special element - the rotor, the ends of which are equipped with blades. Through the latter, hot water is forced to move (namely, in most cases it acts as a coolant) along the main.
To be honest, there are very few susceptible components under the lid. If the pump works correctly, it can work for many years without any complications. In my company, in favor of the client, we do not succumb to his natural economic pressure. We are not going to make such compromises - "let's do something smaller, because it will be cheaper." There is no place for such fairs because they will reflect very quickly in the user's pocket. Don't skimp on how the bottom is made. Also, don't look to cut costs in your heating system.
Most modern models, such as, for example, a 12-watt circulation pump for heating, are equipped with one hydrorotor. However, manufacturers also build two such elements into some devices. Here we are talking about very powerful units that are used for industrial purposes, but not for domestic purposes.
Regardless of the number of rotor blocks, pumps for heating boilers will function effectively only if the heating circuit does not contain air masses inside.
Many investors consider, for example, that the density of pipes in the floor is of secondary importance. This distribution is calculated for each room separately, and attempts to circumvent these results will lead to mourning. What would it be like to install a car with a trolley? And can the driver of such an economy car bring pleasure to anyone? Contrary to the fears of skeptics, heat pumps work well even during severe frosts.
Only properly converted and executed installations can work so well. By accessing the relevant pages, you can monitor the operation of the equipment in many places in the country. The data is very detailed and applies to many parameters. After entering the password, you can also control the operation of the pump from a distance.
Currently, manufacturers of such functional equipment can offer potential buyers two options for devices:
- with a wet rotor;
- dry rotor.
And to understand how these two types differ, let's talk in more detail about each of them.
wet rotor
"Lord, when will he return?"
In case of departure, this allows you to change the settings in the device even from another hemisphere. Thus, it is easy to understand that stories about the high cost of buying a heat pump installation are just a myth! The difference in costs is no longer so shocking. Suffice it to say that in a house up to 200 m², the heat pump has a chance to turn into less than 10 years! It is also worth contacting the Regional Conservation Fund environment. They often partner with commercial banks that provide low interest loans for investment related to the installation of heat pumps.
This type of pumping device is characterized by complete immersion of the rotor assembly in the heat source, that is, in water. The wet rotor pump is assembled according to a special scheme, and its design allows the moving liquid to come into contact with the blades, thereby providing lubrication and cooling of the components of this device.
A clear advantage of such devices is that such a circulation pump for the boiler operates very quietly, which cannot be said about the second model with a dry hydro rotor. This is due to the fact that the vibration and sound waves of a functioning rotor unit are completely absorbed by the liquid itself.
Heat pumps are a fairly recent invention because while we've had them in our homes for decades, we've only recently begun using them to heat interiors. Thus, we do not have many years of experience. Just as a coal-fired boiler is associated with dirt and dust as well as cheap heat, so in the case of a heat pump we don't have such associations. That is why investors are still hesitant to choose a heat source for their home, and a heat pump is a pretty good choice for many of them.
If the home is not located near a natural gas distribution network, you must immediately stop gas heating. And this is the way to get heat for most investors in Poland - the main choice. When gas is not being used, you may consider heating gas from a cylinder, but this is much more expensive - with the price of electricity. Therefore, it is better to focus on electricity.
Water mini pumps of identical functionality and configuration can be used both as the main device (if the heated room has a small area), and in addition to the domestic hot water supply. In addition, such household hydraulic pumps are suitable for heating a private house, and they can also be used for industrial purposes. True, then you need to pay attention to the power of the device, since household appliances are not able to ensure the full circulation of the coolant along a long circuit.
Dry Rotor
This option implies the complete isolation of all component parts of the pumping apparatus from the liquid, thereby providing higher power than the previous model. And this, in turn, allows you to pump quite large volumes of coolant, which leads to the use of such devices to create a thermal circuit in rooms with a large area.
If we compare the two options, then the obvious difference of this type is that, in addition to the location of the functioning elements relative to the liquid, in hydraulic pumps with a dry rotor it is possible to replace the engine with a more powerful one, which makes it universal. But at the same time, vibrations and sound waves will be heard clearly, so it is better to place such devices in separate boiler rooms.
Installation location in the overall system
The connection of the pump to the heating system, as a rule, is carried out on the "return", that is, in the place where the cooled coolant returns to the heating boiler for further heating. However, modern models can be easily placed in any other place, regardless of the location of the boiler.
It is very important that the connection scheme for the heating circulation pump, which is chosen as the main one, allows access to the equipment. Each element of the system needs preventive maintenance and regular maintenance, so a free approach is very mandatory.
For the installation to be effective, it is necessary to adhere to several rules:
- Accommodation expansion tank should be carried out above the level of the extreme point of the thermal circuit by at least 80 cm. In the event that your system does not have a pressure unit, and the water circulates along the main by natural movement, then the expansion tank is installed in the attic. This device can also be installed in highest place the location of the pipeline and radiators.
- The heating block is equipped with a bypass to bypass the forced circulation system. This is true if the pumping device malfunctions or if there are problems with the power supply.
To prevent the accumulation of air masses in the heating main, a Mayevsky valve or special automatic valves should be installed in the bypass or the highest points of the heating circuit to release excess air.
You can buy a pump for a heating boiler at any specialized store, it is only important to choose the right one for power, with which sales consultants can help. By giving preference to centrifugal pumping devices, you equip your heating system unit that will provide comfortable temperature living conditions in your home. Last but not least, make sure you have a warranty. Any complex equipment, including a circulation pump, can fail for objective reasons and without the fault of the consumer.
