For several years now, the market for heat pumps is on the rise. Certainly expensive to buy, such equipment makes it possible to make real savings on its energy consumption. What profitability to expect from a heat pump? Response elements.
How is the profitability of a heat pump calculated?
The profitability of a heat pump is determined by its coefficient of performance, more commonly known as CoP, which is the ratio of the heat produced to the electricity consumed to achieve it. The higher it is (up to 6), the more powerful the equipment is and saves energy. As a general rule, a CoP of at least 3 is recommended for a heat pump of quality, or higher to be eligible, under conditions, to a tax credit.
Also, to this notion is added that of the coefficient of refrigeration efficiency (EER) if the heat pump is reversible, which determines the performance of the equipment in terms of air cooling.
Is the profitability of a heat pump dependent on other factors?
Apart from the CoP, many other criteria are taken into account in order to be able to estimate the profitability of a heat pump, such as the climatic zone, the level of insulation and the heating requirements of the housing for example.
It is thus the union of all these elements which makes it possible to choose a suitable heat pump, and then calculate profitability depending on the purchase cost of the equipment, its installation, its maintenance, or the consumption of electricity necessary for its operation.
How long can you expect to make your heat pump profitable?
The figures set the profitability of a heat pump to less than 5 years on average, for a starting investment around 15,000 euros.
However, these must be appreciated with hindsight. They are based on an optimal use of the heat pump, that is to say the capabilities well adapted to housing, and under the guise of obtaining a tax credit of up to 40%. In reality, the operation of the heat pump can have unpleasant surprises if it is over-sized in relation to the needs, or if the habitat is poorly insulated, then driving loss and over-consumption of electricity.
