Windhager heat pumps are high-efficiency, low-noise air source and ground source systems designed for modern, low-energy homes. They extract heat from the outside and convert it into usable heating and hot water, making them a strong renewable alternative to oil, LPG, natural gas or direct electric heating.
What types of heat pump are available from Windhager?
Air Source Heat Pumps
Windhager's air source heat pumps (AeroWIN range) are high efficiency, low noise systems designed for modern, well insulated homes, as well as larger commercial applications. They work by extracting heat from the outside air, transferring it to a refrigerant, and compressing it to raise its temperature before delivering heat to your central heating and hot water system. The AeroWIN XP offers quiet, low maintenance performance with remote control and scheduling via the MyComfort app, while the newer AeroWIN NXT adds improved efficiency and further noise reduction — making them a strong renewable alternative to oil, LPG, or direct electric heating.
- Environmentally friendly R290 refrigerant.
- Heating and cooling functionality on some models.
- Quiet Mark certified.
- Outputs from 3 kW to 70 kW, suitable for homes through to hotels and commercial buildings.
- Kaskade of multiple units available for higher output requirements.

Ground Source Heat Pumps
Windhager's TerraWIN range extracts renewable heat from the ground via boreholes or horizontal ground loops, drawing on the stable year-round temperature beneath the surface. Some NXT models can deliver flow temperatures of up to 72°C, making them well suited to retrofit projects with existing radiators, and ground loops offer a lifespan of 50+ years — delivering heating and, in some models, cooling for a wide range of building types.
- Environmentally friendly R290 refrigerant.
- Heating and cooling functionality on some models.
- Quiet Mark certified.
- High efficiency, with SCOP up to around 6.3.
- Outputs from around 1 kW to 100 kW and beyond, suitable for homes through to commercial and district heating schemes.

Is a Windhager Heat Pump Right for Your Property?
Here is a list of things to consider when choosing your Windhager heat pump system:
- Best performance in well-insulated homes (EPC C or better recommended).
- Ideal for buildings with underfloor heating or large radiator systems. Some properties may require a radiator upgrade.
- A great solution for properties looking to replace oil or LPG (big savings potential).
- A perfect choice for new builds aiming for low-carbon heating performance.
- An outdoor space is required for the heat pump unit.
Installation Overview
A typical installation includes:
- Outdoor heat pump unit.
- Indoor hydraulic module.
- Groundworks (horizontal trenches or vertical boreholes) for the ground loop, sized according to a site-specific ground survey. (Applicable to ground source heat pump only).
- Hot water cylinder (often required).
- Buffer tank (depending on system design).
- Possible radiator upgrade (Depending on suitability assessment report).
- Smart controls.
The installation process follows the standard UK heat pump steps:
- Suitability assessment
- System design
- Installation
- Commissioning
- Post‑installation checks and EPC update
