FAQ
What is an air-to-water heat pump?
The air-to-water heat pump is like a super-efficient heater that works like a refrigerator but in reverse. It captures free energy from the air outside to heat your home, making it a greener replacement for fossil fuel-powered heating systems that most people in the EU currently use to heat their homes.
An air-to-water heat pump is considered energy-efficient as it can provide more heat energy than the electrical energy it consumes. This makes them a highly efficient, renewable, and sustainable way of heating, cooling, and providing domestic hot water.
How does an air to water heat pump work?
① Evaporation: The evaporator is the place where the refrigerant and outdoor air exchange heat, turning the refrigerant from liquid to gas as it absorbs heat from the air.
② Compression: After evaporation, the refrigerant enters the compressor, which compresses it into a hot, high-pressure gas for the condenser.
③ Condensation: The condenser is the place where the refrigerant and water exchange heat, turning the refrigerant from gas into liquid as it releases heat to the water.
④ Expansion: After condensation, the liquid refrigerant flows through an expansion valve, reducing pressure and turning it back into vapour, and then goes into the evaporator for the next cycle.
