Wonder how it would compare in price?
Currently 10m2 160W/m2 Raychem mat £350
Thermostat £64
And if I had to buy the membrane say about £140
SLC say £40.
So about £600 ( Obviously not including cost of thermal boards)
Try the forum sponsors Uheat. Their variopro system came in under 50% of Ditra Heat price and I get good schluter prices.
Don't forget that the time you save installing these, is profit made.
I'm very limited in choice here. The Uheat stuff looks good and if it's good enough for Imp it'd be good enough for me. Do they do a Ditra heat duo equivalent with insulation built in as well?
