Under tile heating...

wayne77

Hello, anyone have any advice on underfloor heating for a small,tiled floor, upstairs bathroom?
Electrical system specifically.
Thanks, Wayne.

Small? Waste of time and money. Won't provide any usable heat to room apart from taking chill off the tiles.

Cheers

I've installed the Warm-up system quite a number of times now, with no problems. The smallest kit they do is 300watts and as Keystone says, it will be borderline for the space heating requirements of a small room, BUT, I wouldn't call it a waste of time! When I re-did my bathroom a couple of years ago, I kept the radiator as the main source of heat but put in the undertile electric heating. . . . in the winter it's SOOOOOO nice to walk on warm tiles in the mornings!!

Exactly, jayyar. I will keep my radiator for main heat source.

I wouldn't go for the usual electric mats - unless you put a thick screed over them the spacing of the heating elements will mean your floor with alternate between warm and cold within 10cm of each other. This is incredibly annoying. I would go for something like a carbon film heating elements directly under tiles so they only have to heat the tiles, not the screed too - rapid response, much more efficient.
