I have an unvented hot water tank and want to plumb it into a combi boiler. How do i plumb this in?
Answers:
you don't. if you do something wrong you could blow it up and take a bit of your house with it. the law is now that a condensing boiler must be fitted and for this to get the best out of it you need all kinds of sensors to check the combustion, flue gasses etc. get a local heating engineer. it will cost but you will be safe. it is not just on the boiler that safety is important but also your tank. if you set anything wrong on that then it too could explode

Seek pro help from a corgi registered plumber.
You need a CORGI registered engineer to fit the boiler and to fit an unvented hot water cylinder you need someone who is registered and qualified to fit it as both items now have to be registered with your local council building control .I know this because I'm a CORGI engineer ,for my sins !
