Am installing a porcelain tiled floor - onto an existing concrete subfloor. I have decided (after reading the thousands of messages on the subject!) to install electric underfloor heating mats (on top of insulation boards). I am well aware of the economics/advantages/disadvantages particularly in comparison with water systems. It is a playroom with central heating and the idea is only to take the edge off the cold tiles.
There are so many different products/suppliers - Devi, WarmUp, SpeedHeat, Wickes etc etc. Does anyone have comments on good/bad experiences with individual products?
I am intrigued by a product from Rayotec which appears to use cable much closer together thereby making the product thinner, and able to operate at a lower temperature. Any experience of this?
