Heat pump for heating houses: prices, types, installation and myths

Gas, Light, firm and liquid fuel It has become quite expensive. But progress is always striving to reduce the cost of the cost of the consumption of energy. It should be noted that alternative devices that produce heat or cooling energy, have expensive equipment, but the main advantage is a fast payback. One variation of this alternative is the heat pump for heating. Prices and description of types of such systems are lightened in this article.

Provenance heat pumps

The first signs of heat pump concept appeared in 1852. William Thomson has given rise to this development, it has picked up and perfected by Robert Weber in 1940, which is often experimented on freezing installation and randomly I found that from the freezer unit generates heat. At first, scientists have learned the system warm running waterAnd in the end everything home. Grand triumph was placing Weber copper pipes in the ground, who collected natural warmth and converts it into heat energy.

The principle of the heat pump to heat your home

The heat pump is designed so that its internal units could recycle the heat of the environment (water, soil and air) to the heat for building heating.

How does the inside of the pump

Regardless of the method of producing all heat pumps comprise the following elements:

• expansion valve;
• the high pressure evaporator;
• Compressor;
• Capacitor;

The process of transforming

Geothermal heat pump at a good price for home heating It works on the principle of conventional the refrigeratorThat everything accumulates inside the unit heat in the refrigerant boils, displays on its back wall. Just in case heater, Extracted energy is given battery in room.

Stages of creating heat:

1. Depending on the type of natural element, the pump withdraws heat in the range of from 1 to 7 degrees.
2. The evaporator, which is located inside the device comprises a refrigerant. This liquid is able to boil at zero temperature.
3. By using the obtained natural heat, the refrigerant boils and becomes a gas.
4. Gas enters the compressor which increases its pressure and the resulting temperature increases.
5. Maximum warmed refrigerant in gas form enters a condenser where it gives its heat battery heating system. After cooling, the substance returns to a liquid state.
6. Then, the expansion valve passes through a liquid, lowering its pressure to the initial level.
7. And the refrigerant in the evaporator is again receives a portion of the heat and the process repeats.

Consequently, the coolant - is the main operation member of the heat pump. The heat that it receives from nature is converted into heat 35-65 degrees useful resource.

Note! Though heating the coolant temperature is not so large, but by increasing the battery sections is achieved a complete and uniform heating of premises. You can connect a heated floor, it will warm up smoothly and not aggressively.

The main types of heat pumps

Differ heaters method of producing heat. Divided into species such as:. 'Water-water', 'air-to-air "," ground-water "," air-water "

Water-water

The essence of the system lies in the selection of heat from a reservoir or groundwater. Equipment of this type differs from other more heat exchange efficiency. The reason is that water is less sensitive to temperature changes, especially in the ground.

The air-to-air

Thanks to the compressor, energy land can be converted into the air. Whereafter the air passes the heat to the system. This modification eliminates the use of water as the heat collecting pipe placed at the minimum possible depth in the ground.

Ground-water

Thanks to the anti-freeze fluid, which flows through pipes looped, buried at the depth of two meters, achieved maximum protection against extremes of temperature, it provides a complete operation of the pump efficiency.

Air-water

The main feature of these pumps is to limit the installation of temperature conditions. Thus, if the negative temperature threshold is not higher than 15 degrees in your area, then this machine will be the ideal choice for Heating your home.

How to orient the choice of the heat pump

To select a particular type of heat pump for home heating with a good price, you need to determine the following parameters:

• The amount to which you are willing to give up for the purchase of equipment;
• The type of terrain where the house that you're going to provide an alternative method of heating. The location of the rates or groundwater depends on the type of installation;
• You need to decide whether you have the opportunity to drill well a heat pump;
• The main caveat is accurate calculation of the required power for a full home heating;

How to calculate the power required equipment

First of all it is necessary to calculate the exact cubic content of your building, using the following formula: V = Ceiling Height x Width x Length of the building.

To more accurately determine the required power, it is necessary to calculate the temperature difference between the street and the microclimate in the middle of the building: T = Twithin - Toutside = Desired degree Celsius.

Endpoint formula includes a record of all the above parameters: Q = V x T, kW.

Important! To avoid the lack of power for heating, to be added to the resulting estimates 10 percent of the nominal value, in order to balance all the flaws.

Overview manufacturers

In order to buy a heat pump for home heating, The price must necessarily relate to the manufacturer's reputation and the range of functions.

1. Company Brosk It is one of the leaders in the Russian market. Originates from 1995, although the first project was not successful, the study deficiencies and learning from foreign partners allowed the manufacturer to firmly stand on their feet. Now, heat pumps from Brosk companies are not only high-quality and productive, but also to ensure the stability of servicing.

   

2. Heat pumps from the company Henk produced since 2008. Trump card manufacturer, is the use of Copeland's compressor. This company is a leader in the production of compressors in the world market. During the work of Henk was not a single failure of the installed heating them.

   

3. Manufacturer Altal group - it is a rapidly growing company that is constantly improving its products. Management of mobile devices, functional devices work like for heating? and cooling facilities, makes this giant manufacturer in conjunction with the latest technology on the market.

   

4. Smaga - a fairly young company, but success in the field of alternative forms heating. Participants of the event non-commercial partnership AVOK engineers. This membership gives a guarantee of the company's customers in perfect calculations, the design of the equipment.

   

Note! There is a wide range of foreign manufacturers, the quality of the equipment which is very high, but domestic firms do not succumb and are able to outdo many European competitors. The price of Russian manufacturers is much nicer.

Heat pump with their own hands

To create a heat pump for home heating with their hands out of the refrigerator need to have a certain skill. But to bring the machine to working condition is possible.

• The first thing to buy a compressor from the refrigerator or air conditioning.
• Now you need to collect a capacitor structure which begins with the coil. It is usually made with a copper tube of a thickness of 1 mm, and placed in a metal housing. To place a coil inside the tank, it is first sawed in half, and after placing all the parts and screw connections welded back. To obtain flat coil windings and with the same distance between the rings, the tube can be wound on disc, and the distance is fixed area with aluminum fins.
• Complete assembly, welding of pipes and pumping refrigerant only professional refrigeration. Otherwise, it may occur an emergency situation.
• All construction is ready to plug in heating system.

Additional features of heat pumps

The unique design of heat pumps Russian production provide an opportunity to create additional processes such as cooling and heating water Boiler. The cooling effect is achieved due to the reverse refrigerant narrowing process. That is, in the compressor take place the same manipulation as in the heating, only in reverse order.

water in boiler It is heated indirectly. Located inside the boiler coil through which hot water passes, and the heat coil heats the water in the boiler.

Warranty and service

Due to the fact that the system is very complicated, perform diagnostic and repair work on the unit itself is not valid. For these purposes, the purchase of the pump manufacturer is obliged to conclude a contract with you stating the check will be performed at any time periods heating systems specialist.

1. The guarantee means a certain period of free service, which includes repairs of components and assemblies.
2. After-sales service is an integral addition to the system itself. Graph that make the inspection may be monthly, quarterly, semi-annual and annual.

findings

If you have a positive attitude to the fact, to buy a heat pump for heating houses, the price should not scare you. Indeed, the main priority of such heating is that the efficiency is multiplied by 4 times compared with other heat sources. This means that the system will pay for itself very quickly. Warm your winter evenings.
