Recessed floor heat emitters

Simply Rad

I looked at a home built in 1990. The house was remodeled and the Entrane 2 radiant floor was abandoned. The remodel was form over function and the radiant floor replacement is incredibly undersized using radiators where ever they could. Problem is there is no wall space for radiators, as the windows sit about 12" above the floor. Need a lot of heat output, as there is a lot of glass. I have used Myson floor heaters and they work great. But I need a much larger heat emitter-10-15K btus. at hopefully 140F SWT. Any ideas would help

Runtal makes an attractive baseboard model, but you won't find the high outputs you require. The UF-3 is 9" high and output is 770 btu/ft @ 180. I'm not aware of any high output radiator under 24" H. I've built custom recessed radiators using 11/4" steel fin tube. IIRC, Beacon Morris may have some.

This is a large custom home with tall cathedral ceilings. So radiant ceiling wouldn’t work. Jeffrey
