• Pretty well insulated and draught proof. It was built circa 2000, so done to whatever building regs prevailed then. It is the ground and first floor of a four storey building, with a concrete ceiling so not much heat loss through the roof. Circa 50% of walls are external facing. I think there is PIR or equivalent in the walls. Obviously double glazed.

    We used to live in a 2 bed in the same place, and we never updated the convection wall heaters. They were useless, but our electricity bills weren't too awful. I just want to get something as efficient as possible in the new place.

    I guess wet underfloor is an option, but would mean raising the ground floor a couple of inches I think? The ceilings are very high so could be viable. The other option some neighbours have is ceiling mounted heaters, but I don't know much about them.

    There are contractors who specialise in retrofitting wet UFH. They use a machine kind of like a walk behind cut-and-break saw to cut tracks in the floor which the pipes are then laid into. You could DIY it either if you're handy and have the time but it is a rather messy job.

    @Nahguavkire you did this DIY right?

    Can you remember what the rough p/m² cost was of installing wet UFH?

    Also in terms of how it connects to the boiler, is there anything special about it? Ie would a plumber just be picking one of the hot pipe and return feeds from an upstairs boiler and connecting them to that?

    Cheers.
