Instead of an epilogue
Currently, the market for the units under consideration is quite wide and it is difficult to identify a specific leader in it. But the trends are such that for heating swimming pools the buyer prefers a Western manufacturer, for heating small areas - Asian models are excellent, and for home use (heating large areas of private houses) Russian models are also quite suitable. In turn, most supplier companies offer, in addition to the purchase of equipment directly, their services for installation supervision. They are usually provided at a significant discount, so it’s not a sin to take advantage of them. You can purchase heat pumps in retail chains and online sites.

Possible problems and errors
In recent years, the number of companies involved in the design and installation of heat pumps has increased significantly. Accordingly, a number of problems arise when the heating system stops working or functions ineffectively. And then many homeowners find out that simply replacing the equipment is not enough - they will have to plow up the entire area and re-lay hundreds of linear meters of pipe.
All errors can be divided into two large groups:
- mistakes made at the design stage of heating system components;
- negligent performance of work.
An incorrect heating system will either be insufficiently powerful or unstable in terms of the power of the main components. In the first case, such a heat pump is not suitable for heating a country house. In the second case, for example, if the external circuit is poorly selected, there is a danger of the pipeline freezing.

Ground heat exchanger
The ground heat exchanger is one of the key elements with which problems most often arise. It consists of long (several hundred meters) strands of pipe, folded into rings in trenches or placed in one or more wells.
Main criteria for selecting heat pumps
Our experts compared heat pumps taking into account important technical parameters. To select the correct equipment, you need to consider:
- TN type. On the climate control equipment market there are models operating on the “air-to-air”, “air-to-water”, “ground-to-water” principles. When choosing specific modifications, you need to take into account the climatic conditions of the area, the capabilities of the electrical network, and the dimensions of the heated rooms. It is advisable to consult with experts before purchasing.
- Heated area. Among the assortment of our store are models that are designed to work in rooms with an area from 60 m² to 150 m².
- Quality of home insulation. Depending on the heat loss, you will need a device with more or less power. It all depends on the thickness of the building’s walls, the quality of the glazing, the size of the window frames, etc.
- Frequency of operation. When choosing a specific model, you need to consider your goals. There are units for seasonal use, as well as products that are designed for year-round use.
- The degree of readiness of the object. If equipment is selected at the stage of building a house, you can plan to install alternative heating and hot water supply. In this case, the payback of the TN will be the fastest.
- Air conditioning functions. Not all models are capable of operating in cooling mode.
- Brand. Products from trusted manufacturers have an extended service life and trouble-free operation. Models from this rating are distinguished by high build quality and a long warranty period.

Selection of a quality model on the market
Which heating pump should I buy for a private home? How to choose a good manufacturer? In answering these questions, it should be said that it is impossible to give a clear answer for companies. However, regarding the parameters, the consumer must emphasize to himself that the rated power of the device must be at least 0.1 kW. Thus, the performance of the circulation pump will be around 50 liters per minute.
For a private house whose area does not exceed 200 square meters. m. this will be enough. Next, you should take into account the feed height indicator. In order to avoid problems when installing the circulation pump, this parameter must be at least 6 meters. Otherwise, excessive pressure will be exerted on the heating system. The standard diameter of the inlet and outlet openings is 30 mm. The average weight of the unit is 3 kg. With a device power of 0.1 kW, the model on the market should cost no more than 3,000 rubles.
Purpose
The main objectives of the TP are:
- accounting of heat flows and coolant and condensate flow rates
- control of coolant parameters
- regulation of coolant flow
- distribution of coolant among heat consumption systems
- converting the type of coolant or its parameters
- protection of local systems from emergency increases in coolant parameters
- filling and recharging heat consumption systems
- collection, cooling, return of condensate and quality control
- heat storage
- water preparation for hot water supply systems
- shutdown of heat consumption systems
Nutrition
220 V – connects to a single-phase (household) network. This power supply is most often used in models with power consumption up to 3.5 kW.
380 V - connects to a three-phase network, which is usually used in industry. For domestic needs, a similar line is laid separately. In practice, three-phase power supply is more economical than single-phase power supply (with the same power of a constantly operating VT).
220 V + 380 V - a combined option that allows you to power the heat engine from a single-phase or three-phase network.
Refrigerant
TN very rarely uses R22 freon, which is distinguished by its low price and operating pressure, as well as its homogeneous composition (makes it easier to refill the system in case of leaks). Disadvantage: danger to the ozone layer.
The less toxic R134A refrigerant, with similar homogeneity, is more demanding in terms of operating conditions, in particular, it requires the use of polyester oils.
Refrigerants of the R407C and R410A brands are the safest for the environment. But due to the high operating pressure, such freons are used in expensive equipment, and they themselves are not cheap. R410A compares favorably with R407C in its homogeneity of composition. But if R407C leaks, it is completely replaced.
Heat conversion coefficient
Heat conversion coefficient (COP, KPT) is a figure expressing the relationship between the thermal and power consumption of a heat pump. This parameter is used to evaluate the performance of a heat engine.
KPT shows how much thermal energy the device moves, expending 1 kW of electricity. The higher the COP, the more efficient the heat pump is. Modern models generate 4-5 kW or more of heat per 1 kW of electricity (COP – 4-5).
Important: COP is affected by the ambient temperature and the temperature of the coolant at the outlet of the heat pump (supply temperature). As the difference between them increases, the conversion factor decreases. Therefore, for a more accurate characterization of the heat engine, manufacturers indicate the CPT for specific temperatures.
Do not confuse CPT and efficiency (coefficient of performance). Unlike COP, efficiency is always less than 1.
How to sharpen a house under TN
Heat pumps heat a private home differently than gas boilers. They do not heat the coolant “with a reserve”, but constantly maintain a temperature of +40–+45 °C in the circuit. TN produces the best parameters in buildings with low heat losses and low-temperature heating devices.
Therefore, it is better to immediately “sharpen the house for a heat pump” in order to get maximum benefits and not get hemorrhoids.
- insulate the house well;
- completely abandon radiators in favor of heated floors with a minimum pipe pitch so that the coolant temperature is minimal.
