There is a lot of technology around for all kinds of things, you will have heard of solar energy, there is also ground source and air source heat pumps, which can turn cold temperatures into around 35 degrees celsius, the problems are the usual ones, high costs, making it impossible for many people to purchase, which by default means companies dont take the training offered because it is not cost effective for them to do so, the cost of these is around £8000, as opposed to around £2000 to £3000 for a condensing boiler, and the systems take too long to pay for themselves.
