we have an eichler in Terra Linda, It is in original condition means everything is falling apart. the radiant heat was broken 20 years ago and has been replaced with baseboard heater. We heard about Downing Heating has a low profile system which you won't see the ugly duct work on the roof.
We are wondering if any one has use Downing and the Unico heating system? Please send reviews via PM or post in Chatterbox's "Rec Room" forum.
