    Combi boiler fed by pump from tank

    Hi Madrab - thanks for this, appreciate you coming back. One question though: your point to "avoid if at all possible" - did you mean "avoid laying a vertical cylinder on its side" because (a) the drawoff would be 1/2 way down and (b) the heating water in the coil would now have to go in an "up...

    Cheers @MeldrewsMate These are all very good points. Thanks for the idea on using the shower pump to rig up a boost input to the combi on the cold, then a balancing boost to the shower cold in.... I think it's probably a bit of a "hack" though, and liable to end up costing more to rip out. I...

    Hardie Backer/knauf Aquapanel + insulating board

    Hi I've googled extensively for this with no luck. I'm redoing the bathroom, with the bath/shower against the external (215 mm solid brick) wall. At the same time, I'm redoing the other external walls in the house with 60mm PIR backed plasterboard. I want the same thermal effect in the...
