Air source heat pumps

Imagine you live in a very cold place and you want your house to be warm and cozy. You can use something called a furnace, which burns fuel like oil or gas to make heat. But that can be expensive and not good for the environment.

An air source heat pump is like a magic machine that takes the heat from outside and brings it inside your house! Even in very cold weather, there is still some heat in the air outside. The heat pump captures that heat and moves it into your house, kind of like blowing warm air from outside into your room.

But how does it work? The heat pump is made of two parts: an outdoor unit and an indoor unit. The outdoor unit has a big fan that sucks in air from outside. That air goes over some coils that are filled with a special liquid called refrigerant. The refrigerant absorbs the heat from the air and turns into a gas.

Then, that gas goes into the indoor unit, which is usually a big box on the wall inside your house. There's another set of coils in there that release the heat from the refrigerant into your house. That warms up the air inside and makes your house nice and toasty!

The heat pump can also work in reverse, kind of like a magic air conditioner. In the summer, it can take the heat from inside your house and move it outside, which cools your house down.

So, that's how an air source heat pump works! It's like a magic machine that captures the heat from outside and brings it inside your house, for a warm and cozy home without burning fuel like oil or gas.
