kurt Posted October 17, 2005 Report Share Posted October 17, 2005 Someone posted a site where one could obtain equipment & plans for putting together a forced hot air system using water from the domestic tank & cycling it through a closed loop fan coil arrangement. Anyone got that info again? I seem to have lost the link in my overflowing bookmark catalog..... Quote Link to comment Share on other sites More sharing options...
homnspector Posted October 17, 2005 Report Share Posted October 17, 2005 Kurt, I haven't seen plans but those are fairly popular here. Not homemade but made by Apollo. They are very simple and use a standard Grundfos recirc pump. The A-frame coil is very similar to an A/C evaporator. I would think you could make one from an old air handler. Clean the coils out well since it is connected to your domestic hot water and just loop it to the water heater. Circulating pump and blower comes on via the thermostat. Most here use quick recovery gas water heaters. Quote Link to comment Share on other sites More sharing options...
kurt Posted October 18, 2005 Author Report Share Posted October 18, 2005 Hey, thanx Kelly. I'm not thinking homemade; there is a company that makes a system that is ready made & sized to your particular requirements. I think they're based in Evansville, IN, but I can't find my link or other info. Someone in here posted something about a year back, & I'm trying to dig that up.

hausdok Posted October 18, 2005 Report Share Posted October 18, 2005 Hi Kurt, You want either a Hydro-Aire system or a Bio-Radiant system. Both use individual in-wall forced air units fed from the domestic hot water heater through a manifold with a circulator. I'll dig out the link and post it. ONE TEAM - ONE FIGHT!!!
