Heat pumps air / water

This category includes air-to-water heat pumps designed for integration into central heating and domestic hot water systems. These units extract thermal energy from the ambient air and transfer it to a building’s heating circuit using refrigerant cycles. They are suitable for both new builds and retrofit projects where low-temperature heating systems (e.g., underfloor heating or large radiators) are used.

The models available are compatible with various system configurations and can be selected based on specific requirements such as output capacity, mounting options, and control features. They operate with standard electrical inputs and require proper ventilation and drainage for optimal performance.

How to choose

• Assess the required nominal output in kW to match the heating demand of the property and the efficiency of the existing or planned heating distribution system.
• Verify the type and size of electrical supply (single-phase or three-phase) and ensure the installation site meets minimum space and airflow requirements.
• Confirm compatibility with the existing heating system components, such as expansion vessels, circulation pumps, and control thermostats.

Frequently asked questions

Can these heat pumps be installed in confined spaces?
Yes, provided there is sufficient airflow for heat exchange and clearance for maintenance access. Wall mounting brackets are available for some models.

Do they require regular maintenance?
Annual checks of refrigerant pressure, electrical connections, and filter cleanliness are recommended to maintain efficiency and prolong lifespan.
