Excellent suggestion... Do we actually have suitable technology, and, the skills to instal it, available, in enough volume to make a difference?
no we dont....this is all new technology and a lot of training needs to take place, not in just the fitting of said technology, but also of the servicing side afterwards and also training of the public in how to use them, to get the best out of them.
we have fitted ground source heat pumps, air source heat pumps, solar, heated wall coverings and are trialling a few other things, currently none of them come close to Gas as a heating source........and the training to use them is very scarce.
its all good saying yes the plucky brits can do all this, but honestly, its not as easy as it looks and the cost is significant if you have to retrofit them to current properties.
