'Do heat pumps work in cold weather?' is a pertinent question to ask if you're considering investing in this low-carbon technology to heat your home. After all, we rely on our heating and hot water most in the colder, winter months and need to be confident that the heating source we choose will deliver when we need it most.

Heat pumps, particularly air source heat pumps, have been heralded as key to the future of low-carbon heating and reducing our reliance on fossil fuels. However, they typically cost significantly more than gas boilers at present. As such, it's wise to do your homework to ensure a heat pump is right for you and your home when investing.
