I have installed 1/2" lines in the entire 2100 sf of a bungalow. One line per joist space, 250 ft runs, 6 runs, insulated with foil faced fiberglass. With all lines open the temperature in the house if fairly consistant except the ensuite. when the rest of the house is at 19-20 deg the ensuite is 14 and the master is 18. The master and ensuite are at the southwest and northwest respectively. The joist space under the master and ensuite have extra insulation (roxul) and the ensuite has extra aluminum radiators. R-50 in the attic. I am stumped. The kitchen has limestone flooring, ensuite is porcelain, the rest is hardwood. The limestone is nice and warm, hardwood is almost as warm, The porcelain is very cold. The return lines from the master and ensuite seem to come back a bit warmer that the others. The boiler is opposite end from the master but I have the supply and returns wraped in foil/fiberglass between the boiler and heating zone. Help!
