I wish to use under tile heating for one room in a house approx 2 m x 6m. I've got a very provisional estimate of € 6000. Is this about right? it sounds very high to me!
I found these people great as suppliers- check their site and read up on Devi products - they work well for me - you need to decide whether the underfloor is the main heating system or just for background heat and comfort - warming up the tiles
