I'm thinking about buying an undertile heating system for my kitchen. The kitchen has a concrete floor so gets very cold, the tiles I intend to lay over it are porcelain so they will not insulate very well! I have seen a few underfloor heating kits for sale but the prices vary wildly, does anyone have any tips to what to watch out for when undertaking a project such as this or any reputable sellers or brands that I can go to to buy the kit, after all if it goes wrong I'm not likely to dig up the floor and start again! Any help would be much appreciated, thanks in advance for any given,
