How a heat pump for the home works

The heat pump does not burn fuel: it extracts heat from the outside air and transfers it to the home's system, even when it is cold outside. With a single machine you can heat in winter, cool in summer and produce domestic hot water, replacing or supporting the old boiler. It is the solution most new builds and renovations rely on today, because it turns a small amount of electrical energy into much more useful heat.

COP and SCOP: reading the efficiency

The value that counts is the COP, that is how much heat the pump produces for every kWh of electricity consumed: a COP of 4 means four units of heat for one of electricity. The SCOP is the same measure calculated over the whole heating season, and it is the most realistic figure for estimating annual consumption. The higher these indices, the lower the bill. A heat pump paired with a low-temperature system, such as underfloor heating, works at its best values.

How many kW your home needs

Output is expressed in kW and is chosen based on surface area, insulation and climate zone. As a rough guide:

  • 4 to 6 kW: well-insulated flats up to around 80 m².
  • 6 to 9 kW: homes from 80 to 130 m².
  • 9 to 12 kW: medium-sized houses up to around 180 m².
  • over 12 kW: villas and large or poorly insulated homes.

Correct sizing avoids waste and lets the machine work at its point of maximum efficiency.

Heating, cooling and hot water

A reversible heat pump covers the whole year: it heats radiators or underfloor heating in winter and, paired with fan coil units, cools rooms in summer. For domestic hot water you can choose an integrated model or add a heat pump water heater. Compared with traditional air conditioners, here we are talking about a centralised system connected to the home's hydronic heating system.

Replacing the boiler: hybrid or pure heat pump

If your home is not yet optimally insulated, a hybrid solution pairs the heat pump with a condensing boiler, which only steps in on the coldest days. In well-insulated homes, on the other hand, the pure heat pump can cover the entire demand on its own. The choice depends on your building and the type of terminals already in place.

Tax incentives and grants

Installing a heat pump may qualify for the incentives provided by regulations, such as tax incentives where applicable, such as reduced VAT for renovation work, particularly when replacing an old generator. The conditions change over time and depend on the type of work, so it is best to check the current requirements before buying.

The best brands for residential use

Frequently asked questions

Is switching to a heat pump really worth it?
In most cases yes, especially in well-insulated homes or with a low-temperature system. The heat pump produces more heat than the electrical energy it consumes, so at the same level of comfort the annual spend is generally lower than with a traditional boiler.
What is the difference between COP and SCOP?
The COP indicates the efficiency at a single operating point, while the SCOP calculates it over the whole heating season. To estimate real consumption over the year it is best to look at the SCOP, because it takes the different outside temperatures into account.
Does the heat pump work even when it is very cold outside?
Yes. Modern models keep producing heat even with outside temperatures below zero, while reducing efficiency a little. In the coldest areas or in poorly insulated homes you can choose a hybrid solution with a condensing boiler for support.
Is a single heat pump enough for heating, cooling and hot water?
A reversible model heats in winter and cools in summer, while for domestic hot water you can choose an integrated version or add a dedicated heat pump water heater, depending on your family's needs.
How many kW are needed for a flat of around 100 m²?
For a well-insulated home of around 100 m², 6 to 9 kW are usually enough. The exact value depends on insulation, climate zone and type of terminals, so it is always best to start from a calculation of the heat demand.
Can I take advantage of tax incentives?
In many cases yes, through measures such as tax incentives where applicable, such as reduced VAT for renovation work. The conditions depend on the work and change over time, so it is best to check the current requirements before purchase.
