Air-to-Water Heat Pumps

A high-performance home heating solution

Whether you're renovating your home or upgrading your heating system, an air-to-water heat pump offers a reliable and efficient way to enhance comfort and improve your home's energy performance.

Facing rising energy costs and the growing need for energy-efficient home improvement, air-to-water ial properties. By using heat naturally present in outdoor air, they can efficiently heat a home while helping to reduce energy consumption.

Suitable for both renovation projects and new-build homes, air-to-water heat pumps are valued for their versatility, ease of use, and ability to provide an efficient and long-term heating solution for residential properties.

What Is an Air-to-Water Heat Pump?

An air-to-water heat pump is a heating system that extracts energy from the outdoor air and transfers it to the home's heating circuit.

Unlike traditional heating systems that generate heat solely from consumed energy, an air-to-water heat pump harnesses a renewable resource naturally available in the environment. This technology delivers excellent energy efficiency while reducing the amount of electricity required to operate the system.

The heat generated can be used to supply a range of heating systems, including:

  • underfloor heating;
  • low-temperature radiators;
  • some compatible existing radiators;
  • a hydronic heating system tailored to the home's requirements.

Depending on the chosen configuration, the air-to-water heat pump can also provide domestic hot water production, offering a comprehensive solution to improve the overall energy performance of the home.

How Does an Air-to-Water Heat Pump Work?

The operation of an air-to-water heat pump is based on a thermodynamic cycle.

1. Heat Extraction from Outdoor Air
The outdoor unit captures the heat naturally present in the air, even when outdoor temperatures are relatively low.

2. Heat Transfer to the Refrigerant
This heat energy is transferred to a refrigerant circulating within the system. As the refrigerant is compressed, its temperature increases significantly.

3. Heat Transfer to Water
After several stages of compression and heat exchange, the generated heat is transferred to the water circulating through the heating system.

4. Heat Distribution Throughout the Home
The heated water is then circulated to the home's heat emitters, such as radiators or underfloor heating systems, ensuring a comfortable temperature is maintained throughout every room.

Thanks to this technology, an air-to-water heat pump generates more thermal energy than the electrical energy required to operate it, making it a highly efficient solution for heating residential properties.

Why Choose an Air-to-Water Heat Pump?

Reduce Your Energy Consumption

An air-to-water heat pump harnesses renewable energy available free of charge from the outdoor air. By making use of this natural heat source, it helps reduce the energy required for heating while improving the overall energy efficiency of the home.

Enjoy Optimal Thermal Comfort

A properly sized air-to-water heat pump provides stable and consistent indoor temperatures throughout the year. When combined with an appropriate control system, it delivers a high level of everyday comfort while optimizing energy efficiency.

Upgrade Your Heating System

An air-to-water heat pump is a particularly effective solution for replacing an aging boiler or supporting an energy-efficient home renovation project. It helps modernize the heating system while improving overall performance and efficiency.

Embrace a Sustainable Approach

By using renewable energy from the outdoor air, an air-to-water heat pump helps lower the environmental impact of heating while supporting a more sustainable and energy-efficient home.

Where Can an Air-to-Water Heat Pump Be Installed?

Air-to-water heat pumps can be suitable for a wide range of property types, including:

  • detached homes undergoing renovation;
  • new-build homes;
  • replacement of an existing heating system;
  • energy efficiency improvement projects.

The choice of the right model depends on several factors, including:

  • the area to be heated;
  • the home's insulation level;
  • the household's heating and hot water needs;
  • consumption habits;
  • the type of heat emitters installed in the system.

Each project is unique and should be assessed on an individual basis to ensure the best possible performance and efficiency.

Why Is Proper Sizing Essential?

The performance of an air-to-water heat pump depends not only on its technical specifications, but also on proper system sizing.

A properly sized system is able to meet the heating requirements of the home accurately, without unnecessary oversizing or excessive energy consumption. Conversely, an incorrectly sized installation can affect the overall performance of the system and reduce occupant comfort.

The quality of the preliminary assessment, the choice of equipment, and the installation conditions all play a crucial role in ensuring the success of the project.

An air-to-water heat pump that is properly sized to meet the actual needs of the home helps optimize comfort, energy consumption, and the long-term performance of the installation.
