Hi all, As a home project I want to put a combi boiler in my loft space. It is 5ft to the apex and has brick walls where it could be mounted. The old system is in an airing cupboard although I wish to utilse this space for an ensuite.lastic pipe I don't trust either but still use it in small quantities, but pipe away from the boiler in copper. Is your mains water up to a combi can, remember the higher you go the lower the pressure, that includes volume as well as pressure.
