Tips for choosing your heat pump

More and more homeowners want to use non-polluting energies for heating or air conditioning their homes. Several techniques are used to naturally regulate the temperature of a house. One of them is to install a heat pump.

What is a heat pump ?

A heat pump is a device that makes it possible to perform what is called thermal transfer. The principle of operation is very simple. Thermal energy (calories) is transferred from a low temperature medium to a high temperature medium. The advantage of the pumping device is that it can be used as heating if you act on the hot source and increase the temperature. Conversely, if you act on the cold source, it allows you to refresh. Thanks to a heat pump, we can both have heating and air conditioning. It is more commonly called reversible heating. In order to guarantee its efficiency and economy, it is of course essential to find the right professional to install a heat pump.

What is the principle of operation of the heat pump ?

We will limit ourselves to the compression system which is the most widespread on the market today. There are currently three types of heat pumps:

  • The aerothermal pump
  • The hydrothermal pump
  • The geothermal pump

Choose from the different types of heat pump

The aerothermal pump

The aerothermal systems use the energy contained in the air to heat or cool the ambient air in a home or to heat sanitary water. The advantage of this system is that it is reversible and that it is possible to adapt the temperatures to different rooms in the house. This allows you to better regulate your heating in winter and save energy. Air-to-air heat pumps are generally more expensive than air-to-water pumps (20-60%), but you can get more subsidies to buy the seconds. Nevertheless, it should still be noted that aerothermal heat pumps are much less efficient than geothermal and hydrothermal heat pumps. They only offer a coefficient of performance from 3 kWh.

The hydrothermal pump

As the name suggests, the cold source of the hydrothermal heat pump is water. This can be drawn either from a lake, from a water table or even from a river. In the case where it is necessary to draw from a water table, it is necessary to carry out a borehole in the garden more or less important. It is for this reason that this type of installation requires on the one hand a declaration in town hall, of the DREAL and on the other hand, to appeal to a company approved by ADEME. Hydrothermal heat pumps are very efficient water-water systems since they offer a coefficient of performance of 5 kWh.

The geothermal pump

This system allows capture energy from the ground. When there is a large lot (twice the size of the house), it is possible to carry out a vertical collection at shallow depth. In the other cases, it will be necessary to carry out a drilling, which implies various administrative formalities: declaration in town hall, declaration with the DREAL … Nevertheless, with a coefficient of performance of 5 kWh and the possibility of obtaining assistance from the ANAH, it is a very interesting investment and very profitable in the long term.

You will understand, heat pumps make it possible to produce clean energy while benefiting from aid to reduce your investment.
