My ceiling panels worked fine for 25 years or so, then started failing at an alarming rate. Presently some rooms have no heat while most others have a reduced wattage. Problem with this system is it's in the ceiling and far too expensive to replace. ($5000+now) Much easier to switch to baseboard. I installed these panels with the understanding they were warrantied for as long as I owned the home. (I guess not). Nice while they lasted, but I would never install again.
