Any websites that expain how a home heating and plumbing system works. I have a boiler and radiators but am unsure how to set the system up to run efficiently.
Hiya, not sure about websites, but have a look in you local library, they should have some books to help. Also B&Q do 'How to....' leaflets.
What you do need to remember is that(in the UK at least) all gas appliances should be installed by a Corgi Registered Engineer.
