can't get enough heat

tony elia

i actually ran 2 seperate programs on this structure and the problem area has a loss of 600btu more than the other space. all the sub floors are 3/4 plywood with 3/4 red iok floring and no fire place. this is the master suite.

radiant wont heat

i currently have a plated radiant floor system with 4- zones, evenly divided. the 2 end zones are identical with 4-loops each 150'. we piped it in reverse return.the farthest end zone and the 2 middle zone are perfect 70deg, the other end zone wich is over the boiler and closest won't heat above 64deg.i have raised boiler water to 145deg in an attempt to raise this zone up, it did help somewhat and i have taken the boiler off reset.none of the loops exceed 150'wich should be ok for a 007.

look at flooring

and heat loss to these rooms are they larger ? are they carpeted , what type of underlay , size of windows and doors , fireplace ? there is a free heat loss calc on this web site use it and see what you need for each space
