The below grade basement on my 1970s rancher is a great recreation
room, and now we are planning to replace the indoor/outdoor carpet
over the concrete floor with something warmer. I'd really like to go
with radiant heating & tile instead of the electric baseboard heaters
we have now.

Does anyone have any experience with the Danfoss LX cable
installation? This stuff seems expensive for a 500 sq foot area, but I
really like the idea of one small cable lying in the thinset. I'm
thinking about converting the three 240V 15A baseboard heaters into
under tile heat. I'm comfortable laying the tile, and I would bring
in an electrician to hook up the system.

From what I can tell, this could cost quite a bit, but since I plan to
live here another 20+ years, I might just go for it. I thought about
hydronic, but the ceiling height is only 7' 5" and I want to avoid
loosing height.

Any advice?
