Air conditioning technology has incorporated heat pump technology for over 30 years. Air to water heat pumps are a descendant of this, transferring heat into water instead of air. Major manufacturers like LG, Daikin, Fujitsu, and Mitsubishi have brought systems to the market, with many showcased at renewable energy shows like EcoBuild. After over a decade of installations in homes, swimming pools, and commercial properties, air to water heat pumps have become a proven technology.
 
How it works:

- Easy to install and low maintenance.
- Outdoor unit collects heat from ambient air using a heat exchanger.
- Uses refrigerants like R407C, R32, R410a, and R417a.
- Compresses the refrigerant to deliver heat efficiently.
- DC inverter compressors offer around 4.0 COP (Coefficient of Performance).
 
Key Advantages:

- No need for ground source piping.
- Space-saving installation.
- Cost-effective compared to ground source systems.
- Functions even when temperatures drop below -20°C.
 

Where to Use Air to Water Heat Pumps

 
The main uses include:
✅ Home heating
✅ Swimming pool heating
✅ Properties with no mains gas

They operate with minimal electrical consumption and are ideal where space or land is limited. They remain efficient even in freezing conditions.
Air to Water Heat Pump Limitations
 
- Reduced efficiency in extreme cold.
- Requires defrost cycles to remove ice build-up.
- Outdoor unit must be elevated and have good drainage.
