Heat pumps may not look like a hugely sexy technology, but what they do is pretty magical.
Like fridges in reverse, they move heat from the air or ground outside into your home to warm your radiators or water. While they use small amounts of electricity to operate, they are a very low carbon way of heating your home overall.
Heat pumps can also provide air conditioning, which may become more and more useful as we see more heat waves during the summer months.
Compared to the most efficient gas boilers currently available, a heat pump will save on average over 2 tons CO2 per year. That’s big, considering that the annual carbon footprint for someone in the UK is on average 12 tons per year. Homes across the UK will therefore need to move to heat pumps if we are going to meet our net-zero goals.
How to choose a heat pump
Installing a heat pump is a major climate action you can take. It’s also a major decision in terms of investment, so here we provide a 12 point step-by-step guide on everything you need to do for getting a heat pump installed.
1. Consider what kind of heat pump would work for you
There are lots of different types of heat pumps, including air to water, ground source and hybrid heat pumps. Below we outline the different kinds.
Most people go for air source heat pumps, as they don’t require much space and can be fitted in almost any home. If you have a garden or large outdoor space, then you may also want to consider a ground source option.
Whatever heat pump you choose, they are a substantial investment, so it’s important to make sure you get the right one. Air source heat pumps are on average around £6,500, while ground source will cost more like £13,500 including installation.
