at the time Choose a heat pump for your home, one of the essential criteria to consider is its energy efficiency. The Coefficient of Performance, or COP, is a key indicator that allows you to evaluate this efficiency and thus save money on your energy bill. In this article, we will explain to you what the COP of a heat pump is, how it is calculated and the factors that influence its value. In addition, we will give you some tips to improve the efficiency of your current installation.
is the coefficient of performance (COP). A ratio that measures the energy efficiency of a heat pump. It corresponds to the ratio between the thermal energy (heat) produced and the electrical energy (electricity) used to drive the pump:
COP = Thermal energy produced / Electrical energy consumed
Example :
For a heat pump that consumes 1 kWh and releases 3 kWh of heat, the COP coefficient is 3
Thus, a high COP indicates that the heat pump produces a lot of heat for less electricity consumption, which means that it is very efficient and economical to use.
COP values vary depending on heat pump technologies:
Please note, however, that these values are indicative and may vary depending on usage conditions and specific characteristics of each model.

The COP of the heat pump is determined by Tests are conducted in a laboratory, according to standardized conditions defined by international standards. These tests make it possible to measure the energy efficiency of the heat pump under different conditions, especially depending on the outside temperature and the water in the heating circuit.
Knowing that actual conditions of use are often different from those expected in the laboratory, it is necessary to consider the factors influencing COP to estimate your installation:
Performance of heat pumps Mostly depends on outside temperature and especially on aerothermal systems. As the temperature decreases, heat exchange between the outside air and the refrigerant becomes more difficult, leading to a decrease in COP.
A properly sized and well built installation Helps optimize the COP of your heat pump. It is therefore recommended to call a competent professional to select and implement your system.
Regular maintenance of your heat pump Ensures its proper functioning and avoids loss of efficiency. Do not hesitate to follow the manufacturer’s recommendations and call a professional if necessary.
If you want to improve the coefficient of performance of your heat pump and thus save energy, here are some tips:
