In recent years, heat pumps have become an increasingly popular heating option. An ecological alternative to classic central heating furnaces is also an excellent convenience for users. Are you building and planning to install a heat pump or renovating your house and want to focus on ecological heating? Check which heat pump to choose. We advise you!
How do heat pumps work?
Heat pumps are an alternative solution for heating residential buildings, definitely more environmentally friendly than traditional coal furnaces. Depending on where the energy used to heat the building is taken from, ground heat pumps , air-to-air heat pumps and air-to-water heat pumps are used. The general mechanism of operation is quite similar, the heat pump draws energy from the environment into the building. Then this energy is used to heat the building, and additionally makes hot utility water available.
Regardless of where the energy comes from (air, ground or water), it is transferred to the heat pump, where it is processed in a compression and expansion process, resulting in heating of the residential building.

How much does a heat pump cost?
When looking for the right RES heating methods, it is worth considering all possibilities, guided by the knowledge of specialists. The prices of entire installations vary, depending on the technology used, as well as the size of the building that will be heated. The surface area is one of the most important factors to consider when choosing a specific heat pump variant.
The cost of a heat pump, along with all the necessary accessories for installation, is a considerable expense. Experts estimate that for a small house it is an expense of around 20-30 thousand zlotys, and for a house with an area of approx. 150 m2, the average expense is around 40 thousand.
How much electricity does a heat pump use?
The consumption of electricity in heat pumps is quite diverse. When looking for information, it is worth paying attention to the COP efficiency coefficient. It determines how much electricity and heat energy is used and delivered at a given moment. This is an important parameter that allows you to compare different product variants to choose the optimal one for your needs.
In order to initially assess the operating costs and electricity costs that the heat pump will generate, you need to check the SCOP coefficient of efficiency. You can calculate it using dedicated calculators. The SCOP coefficient allows you to determine the amount of heat energy that will be supplied to heat the house, in relation to the amount of electricity that was consumed by the heat pump during the year.
In order to find out the approximate costs of electricity, the estimated value of the building's heat demand should be divided by the SCOP coefficient. Then the result obtained should be multiplied by the price of the kW unit, which illustrates the level of costs for heating with the building's heat pump.
Average calculations indicate that heating an area of approx. 100 m2 will require approx. 2000-3000 kWh, but these are approximate values, as the exact cost depends on factors such as the temperature maintained in the building and the building's energy standards.
Recommended heat pumps
When looking for the right heat pump model, you should approach the subject individually, taking into account the parameters of a specific project, including the energy standards of the building and its area. The best solution is the help of specialists who will help you choose the most effective solution.
One of the recommended solutions is the R32 monoblock three-phase 14 kWh air pump from LG. A big advantage here is the energy class A+++. In addition to the possibility of ensuring effective heating of the building, you can also easily ensure constant access to hot utility water. The device is characterized by high efficiency and reliability.
Another noteworthy solution is the De Dietrich brand pump - the Alezio AWHP 11 MR single-phase air pump , which is an air-to-water pump. The solution allows not only for heating a flat or house, but also for cooling and even using air conditioning. Single-phase models are less efficient than three-phase ones, so in buildings where it is necessary to use higher heating efficiency, three-phase solutions must be used.
