I have a newish gas forced hot water heating system that is talking hours to move the temp in the house a few degrees. The house it small, 1000 sf, and tight and it is only 30 degrees out.
My heating system has one Taco cartridge circulator 007-F5 and the body of the cartridge is extremely hot and it is silent except for a little hum on the electrical control. It is placed on the return side of the line and there the line is warm but not hot. The radiators are warm but not hot.
Is this normal?
Thanks
