Does heating the house with the heat pump save money?

With recent increases in the cost of electricity and the temperatures in February which are back in line with the increasingly lower winter values ​​of the season, a topic that has become very topical is that of saving for heating of your home. As an alternative to the classic radiators hanging on the walls and the floor heating system, many citizens are wondering if it is worth considering the option of installing a heat pump to mitigate the air of the house.

But how does this alternative method for housing work? Heat pumps work by transferring thermal energy from a colder environment to a warmer one. In practice, the mechanism that must be imagined is that which consists in extracting the heat from one natural source (be it air, water or soil) and to transport it inside the building, so that the temperature reaches the level set according to the different types of systems that are already installed in our homes ( autonomous or centralized boiler in an apartment building; preset air conditioning or use of the thermostat).

Heat pump: the different types and relevant laws

Going to read what the European legislation in this regard, if the heat captured by a pump significantly exceeds the amount of energy necessary for its operation, the device is included among those currently considered renewable. Among the most popular heat pump models to date, there are certainly the ad conditioners electric energywhich also act as cooling systems during the hot season.

But they exist different types of pumps on the market at the moment. An important difference concerning their operation, for example, is that which identifies a substantial difference between the various sources from which the heat is taken, which can come from the air, water or ground. These are all aspects that are difficult to understand for an ordinary citizen, who struggles to move and orient himself among the many laws that regulate this area. In fact, in addition to the diktats coming from the EU, they exist differences between region and region and, in many cases, even between different municipalities even if logistically close.

Heat pump: does saving on the bill really exist?

However, what interests each of us is whether it is really convenient to install a heat pump inside your home. Among the advantages deriving from such a choice there are certainly the tax incentives provided for by the Ecobonuswhich allows a deduction of 65% spread over time over ten years. Furthermore, it should be borne in mind that anyone who decides to install a device of this kind can benefit from the Thermal Account: this is a subsidy to increase theenergy efficiency of its real estate unit through renewable sources. The reimbursement covers up to a maximum expense of 700 euro and takes place by bank transfer.

Finally, the most important factor must be evaluated, namely the effectiveness of this domestic space heating system. The coefficient of performance of a heat pump can reach up to a value of 5 (those of the other types of systems range from 3 to 4 on average): this means that it is able to produce up to 5 kilowatt hours of thermal energy starting from just one electricity. And so the average savings in the bill for an Italian family goes from a minimum of 40% up to 70% of the most advanced systems.
