We're due to have a loft conversion shortly and the builder recommended a combi boiler because it would both remove the tanks from the loft, and facilitate the installation of the loft radiator(s) and shower.
However, as our standard pumped system isn't too old (perhaps 7 years), and we have a £350 power shower which would have to be replaced if we went with a combi, we're considering keeping the existing CH system.
I know we can add a shower / toilet / vanity to the loft room either by installing a coffin water tank very high in the roof (to maintain a head of water), or by using a negative head pump.
My question is about a loft radiator. Am I right in thinking the feed and expansion tank has to be above the highest radiator in the house? And will a standard pumped system be able to pump water upstairs to a loft radiator?
