He is already discussing the proposal to ban the sale of autonomous gas boilers from 2029, included in the European Commission’s RePowerEu plan. The goal would be to replace them with heat pump systems, which would allow (below we will try to explain the reason for the condition) to reduce energy consumption. A necessary premise: it is a proposal that must reach the European Parliament and which, in any case, requires national implementation. The retracement of the ban that should be introduced on the sale of properties with low energy classification, made in recent months, is a precedent that could give us food for thought.
differences
From a technical point of view, the difference between a gas boiler and a heat pump is very clear: the boiler needs a fossil fuel to heat the water that circulates in the heating system and in the water system. Consumption is also very high because, for instant hot water production, the water in the circuit must be kept at a temperature not much lower than that which comes out of the tap or heats up the radiators. With a heat pump, on the other hand, there is an exchange between the outside air or the water or the ground and the air or the water in the circuit; There is no fossil fuel, but electrical energy that activates a pump and compresses the freon gas it contains, which transfers heat to the circuit. In practice, this is the reverse process compared to that of the refrigerator. In the more expensive models, the pump also works like that of a refrigerator and in this case supplies the rooms with cold.
The savings
How much are you saving? Depending on the use (in continuous operation the consumption is lower because the pump has to work harder in the first hours of operation) the consumption estimates are reduced by up to 50%; However, some aspects need to be considered. The first is that the autonomous boilers take up little space, a heat pump needs outdoor space, for a house it’s fine, but in a condominium the solution of the single heat pump is often impractical and you have to resort to a centralized heat pump. The second (and here we explain the use of the condition made at the beginning) is that the less efficient heat pump is where the outside temperature is lower and where there are radiators instead of radiant panels. This can be avoided by using more powerful systems or measures such as insulating the pipes, which of course increase the initial cost. In any case, the choice of a heat pump should be made after an inspection by a technician who will indicate the optimal solutions for the building.
Bonuses for cost reduction
Last but not least, when it comes to costs, keep in mind that heat pumps currently have the opportunity to get the 110% super bonus as a driving force, single boilers get a 50% tax rebate, so if you have the opportunity ask them Concessions did not match. Knowing today what the bonuses will be in 2029 is not possible. As for the prices without tax credits for condensing boilers, it ranges between approximately one thousand and two thousand euros. For heat pump systems, the correct indication seems to us precisely because, as we have said, each system refers to the Ministry’s price list, which indicates the maximum costs (VAT, professional services and installation excluded) that can allow for the purposes of the Superbonus will. For air / air systems (the least efficient, not recommended where winter is harsh) the cost of 720 euros for each kilowatt of power; for air/water or water/water systems it rises to €1,560 and for geothermal heat pumps to €2,280.
