Hi
Been considering options for a new heating system in a bungalow renovation project.
Bungalow has approx 10 rooms (4 bedrooms, 2 bathrooms, living room, kitchen, dining, utility room & entrance hall with long corridor down middle with all the rooms coming off the corridor. Total floor size is approx 180m2. Current system is oil fired boiler with rads, want to get rid of that and go all electric (don't want rads or a big oil tank outside, this is non negotiable, hate rads and hate oil tanks).
Consumer unit is quite large with lots of free slots and the main fuse is 100a.
Looked at electric ufh first (sticky mat type) but worried about the load on the electrics (would be approx 21kw as quoted by Fastwarm, or 111amps on out 225v supply), this may be doable but we'd obviously need to stagger run times for each room so that it's not all running at once. I'd say max draw would be no more than 9kw/40a, at any one time.
Now considering wet underfloor heating from Nu Heat.. the LoPro Max. Any experience of this? They claim you don't need to fit insulation under it if on a solid concrete floor and it can go straight over existing floors (our floors are concrete/tiled), I'm not convinced by this though, surely you'd need some insulation to prevent downward heat loss?
If we went for a wet underfloor heating system like this can it be fitted a rom at a time and added to, it'd an ongoing renovation project, living in it and doing 1 room at a time so not really practical to be doing it all in one go.
Thanks for any help,
