hydronic floor heat complicated
ok first off thanks for any and all help with my system!!
house was built in 2016 slab on grade 1/2 pex 12" spacing all but 1 loop is around 300' 6 loops total
hot water tank is also used as boiler k030-16m-np6 brazed heat exchanger for in floor primary loop ( I can take pics )
outdoor wood/coal boiler b3-32a-20 brazed heat exchanger for that boiler loop
3 zone valves 3 stats although I have now made the living rm stat centrally located the 1 main stat for all 3 zone valves ( didn't lay in floor tubing correctly for separate zones. I have pictures before the concrete pour.
circ pump for floor loops is a 007-f7 taco pump
if I remember correctly I only get about .25 gpm on each loop if I turn down the other 4 loops and only do the 2 loops that are the farthest away ( babies room/ office ). I can get .5 gpm max
problem is I can't get the farthest 2 loops to make good heat, living stat at 70deg and the babies room is at 65-67 max wife is not happy with that for the baby! lol. rooms are carpet with correct padding for radiant heat. rest of house is vinyl flooring.
I know you guys will need more info but basically just looking to get some opinions on the system design if its way off or close to correct.
