Hi, i am a new member, after a quick look on the web for information about ashp, I find myself here, my lodge home is under construction and I am keen to install ashp air to water for ufh and dhw, I came across some info that was 4 years old and has opened my ears, I am not too bothered about the RHI and using MHS certified installers as the general opinion of expensive and a bit of a catch 22 situation. I have good plumbing skills and some experience of electrical installation. My first question is what brands are worth a look and where's best to buy? Cheers Bob
