    How does an air-to-water heat pump work, and what are the advantages of heat pumps over traditional heating systems?

    The transformation of calories from the air by a heat pump

    An air-to-water heat pump uses the heat from the outside air to efficiently heat your home. This innovative system captures heat from the ambient air, converts it into energy, and heats the water in your heating system. This environmentally friendly and economical process reduces fossil fuel consumption and lowers heating costs.

    Unlike the air-to-air heat pump which draws energy from the outside air and returns it as hot air, the air-to-water heat pump draws calories from the outside air, but uses water to transport the heat.


    Most air-to-water heat pumps come in the form of a single unit. They consist of four components:

    • the evaporator, which ensures the transformation of the refrigerant into vapor;
    • the compressor, which increases the pressure and heat of the gas;
    • the condenser, which allows the refrigerant to transfer heat to the heating water;
    • the pressure regulator, which reduces the pressure and temperature of the gas.


    Heat pump: operation and energy efficiency

    The heat pump uses electricity to produce heating, primarily through an electric motor that compresses the refrigerant. This process allows it to efficiently capture and distribute heat throughout your home.

    The efficiency of a heat pump is measured by its coefficient of performance (COP)This indicator expresses the ratio between the thermal energy produced and the electrical energy consumed. The higher the COP, the more efficient the heat pump. For example, an air-to-water heat pump with a COP of 3 generates 3 kWh of thermal energy for only 1 kWh of electricity consumed, thus providing economical and environmentally friendly heating.

    Electricity consumption of a heat pump and return on investment

    Air-source heat pumps: operation and efficiency

    Air-source heat pumps, such as air-to-air heat pumps And air-waterThese systems utilize outside air to power your heating system. The generated heat is distributed through fan coil units, radiators, or underfloor heating, providing optimal thermal comfort.

    Their effectiveness is measured by the coefficient of performance (COP)For example, a COP of 4 means that for every 1 kWh of electricity consumed, the heat pump delivers 4 kWh of thermal energy. The COP is easily calculated using the following formula:
    COP = kWh produced / kWh consumed.
    The higher the COP, the more efficient and economical your heat pump is.

    Top 10 questions about heat pumps?

    • Is an air-to-water heat pump sufficient for heating during a cold winter?

      While the efficiency of an air-to-water heat pump decreases as the temperature drops, it remains effective in providing sufficient thermal comfort down to sub-zero temperatures. The most efficient models can even operate down to -25°C. However, connecting it to a backup heating system may become necessary when outside temperatures fall below -5°C. The performance of your system also depends on the insulation of your home. It is also crucial that your installation is carried out by a professional who will have sized it according to your location, living area, home insulation, and your specific needs.

    • Can I install an air-to-water heat pump without authorization?

      Installing an air-to-water heat pump does not require any special authorization, unlike geothermal heat pumps, which require excavation or drilling work.

    • Can a heat pump be connected to an existing heating system?

      You can only connect a heat pump to a central heating system. This means that to install a heat pump, you will need water radiators or underfloor heating. This does not mean that you cannot install an air-to-water heat pump if you have an electric heating system.

    • Can an air-to-water heat pump be used to air-condition a home?

      Yes, because the vast majority of low-temperature air-to-water heat pumps are reversible, meaning they have an option to reverse the process and cool a home.

    • Are heat pumps noisy?

      The noise level of a heat pump depends on the heat source and the design. With modern heat pumps, the noise level is lower than that of rain. Before buying your new heat pump, it's best to compare manufacturers' information on noise levels at different operating points.

    • Can hot water be produced with a heat pump?

      There are air-to-water heat pump models capable of producing domestic hot water. In this case, you will need to invest in the installation of a thermodynamic water heater. The thermodynamic water heater operates on the principle of a heat pump and can heat up to 1,000 liters of hot water per day, depending on the model, producing hot water economically and ecologically in new or renovated homes.

    • When should I service my heat pump?

      Generally, it is sufficient to have the heat pump inspected by an installer once a year. Heat pumps require virtually no maintenance and therefore incur very low maintenance costs.

    • Are refrigerants harmful to the environment?

      There are synthetic and natural refrigerants for heat pumps. Synthetic refrigerants generally have a high global warming potential and are therefore harmful to the climate. In contrast, modern refrigerants such as propane (R290) have a low global warming potential.

    • Where should the outdoor unit of a heat pump be placed?

      Since you want to capture heat from the air, it's best to install the outdoor unit of your heat pump on the warmest side of the house, ideally facing south, and sheltered from prevailing winds. The recommended distance for installing a heat pump is 15 to 20 meters. In any case, this distance is usually factored into the sizing of your heat pump.

    • Can the outdoor heat pump unit be covered?

      There are several ways to seamlessly integrate a heat pump into the aesthetics of an outdoor space. It is important that both the air intake and air outlet of the heat pump are easily accessible.
