Title: Seperating floor heat form central air
Post by: fryedaddy on November 12, 2014, 07:29:54 AM

Currently my system is ran through a large loop with (2) hvac units then into the floor.

I'd like to seperate my floor heat from my HVAC units. I have (4) lines running into the house.
(2) going to and from the HVAC/Floor system and (2) going to my DHW.

Could I seperate the floor, run a loop for the DHW with heat exchanger and run my floor from that "zone"?
 
Let me know if info is needed.

With the line that runs to your DHW, assuming that you have a side arm or FPHE, to seperate drinking awater from BOILER WATER !!
All you should have to do is add a set of closely spaced tees on the return (between DWH and OWB), add a mixing device to drop water temps below 120f (assuming inslab), install a pump (between mix device and radiant manifold) and air units are seperate from floor. Controls may get a bit complex, but I am guessign at a minimum you will need a seperate thermostat and relay to turn pumps on but other than that, you should not need too much more.

But like always  :photo: are nice
