This guide will cover everything you need to know, from how these systems work to why they're becoming increasingly popular across Europe. So, grab a cup of coffee, and let's get started!

What is an Air to Water Heat Pump?

Okay, so what exactly is an air to water heat pump? Simply put, it's a heating system that extracts heat from the outside air and transfers it to water, which then heats your home through radiators, underfloor heating, or even your domestic hot water supply. Sounds like magic, right? Well, it's actually science! Even when the outside temperature is quite low, there's still energy in the air that these pumps can extract. This makes them a super-efficient alternative to traditional heating methods like gas boilers or electric heaters.

How it Works:

The process involves a few key components:

Outdoor Unit: This part sucks in the outside air and passes it over a refrigerant-filled coil.
Refrigerant: The refrigerant absorbs the heat from the air and becomes a gas.
Compressor: The gaseous refrigerant is then compressed, which increases its temperature even further.
Heat Exchanger: This is where the magic happens. The hot refrigerant passes through a heat exchanger, transferring its heat to the water in your heating system.
Expansion Valve: The refrigerant then goes through an expansion valve, which reduces its pressure and temperature, turning it back into a liquid and ready to start the cycle again.
