What are the 5 Best Air Source Heat Pumps?

[Libby]

I’ve just had a Grant, which has an A+++ rating. They’re a British company and offer 4 different models - I don’t have access to the price range. The guarantee is only 7 years. If I’d seen your review first, I might have gone with a different option, but I could only get 2 installers to quote and they were much of a muchness. So far, it’s all been satisfactory, with plenty of heat and hot water, but too early to tell yet about the running costs.
