Hi, can anyone help me with what I would need to install an unvented direct hot water system. My stepdad is installing it for me, but I think he is being sold to by the guys at B&Q as it seems to be costing a hell of a lot and we are trying to do things as economically as possible (baby on the way) so I just want to check.
The hot water tank will be fed direct from the mains and will be used to provide water to a one bed flat.
All help gratefully received.
