When you’re thinking about different ways to heat your home, the chances are that 3 systems spring to mind: gas boilers, oil boilers and electric heaters. But have you considered heat pumps? They run using electricity but extract heat out of the ground and air to heat your home.
If you’re thinking about new ways to heat your home, it’s worth finding out more about heat pumps. Keep reading to learn more about the 3 different types of heat pump you can use to heat your home.
Ground source heat pump
Average cost: £10,000-£18,000
Top benefit: Could lower your heating bills and save you money through the RHI
Main disadvantage: Expensive and can be a hassle to install
Ground source heat pumps have been around for a while but not everyone knows how they work. They’re made up of a series of pipes buried in the ground. These contain a mixture of water and antifreeze and absorb heat from the ground. The water and antifreeze then go through a heat exchanger and into a heat pump, which powers your home and water heating.
Ground source heat pumps aren’t that common, partly because of how they need to be installed. The pipes need be laid around 2 metres deep into the ground, although they can be laid deeper and vertically instead. If you want to install a ground source heat pump, you’ll need some outside space that can be accessed by excavating machinery.
If a ground source heat pump sounds like a great way to heat your home, you’ll need to check that it’s compatible with your property. A ground source heat pump works best with a wet underfloor heating system, as this requires cooler water than other water heating systems. However, it is also compatible with radiators. It’s also a good idea to make sure that your home is well insulated before you install a heat pump.
A ground source heat pump can be a hassle to install, but it can be cheaper and more efficient than your current system.
Air source heat pump
Average cost: £6,000-£8,000
Top benefit: Less expensive than a ground source heat pump, and can also lower your bills and save you money through the RHI
Main disadvantage: You’ll probably need a different system to heat your hot water supply
Air source heat pumps use energy from the air to heat your home. You don’t need much space for an air source heat pump, just some exterior wall or ground space that has good air circulation. This means that they’re much easier to install than ground source heat pumps and are more likely to be compatible with your property.
There are two types of air source heat pump:
Air-to-water air source heat pumps
Air-to-water air source heat pumps heat water, which can be used to heat your home. These work best with wet underfloor heating systems. You can use an air-to-water heat pump to heat your hot water supply, but other heating systems are usually more effective.
Air-to-air air source heat pumps
Air-to-air air source heat pumps heat air, which is distributed around your home with fans. You can’t use air-to-air heat pumps to heat water, but you can use them to circulate cool air around your home in the summer.
Air source heat pumps don’t tend to be a great way to heat your hot water supply. But they can be a cheaper way to heat your home than your current system.
