In the process of converting my attic. Space for two bedrooms and a bathroom (bath, shower over, toilet and wash basin) plus a landing area. Ignoring the attic, we already have 4 bedrooms, 2 bathrooms (both with showers) and an ensuite (shower and basin only). Considering what to do with attic heating and hotwater. Currently have an unvented megaflow 210l hot water cylinder and two boilers in parallel running the system in the rest of the house.
I thought initially about a separate combi running the attic water and heating but not keen on the pathetic hot water from a combi (used to have one in previous property - valliant supposedly pretty good but broke down a couple of times and bath took forever to fill etc). Just recently thought about two unvented cylinders in parallel but no room to do this next to each other. Could one be above the other in the attic? How far apart can they be? Is this sensible? Any other ideas to avoid the combi water issue?
