i am having a problem with a monoflo system and need advice. the house is a 55 year old story and a half (cape cod). the trunk line is 1" copper with 3/4" branches. all rooms have copper fin tube baseboard. the five baseboard convectors on the first floor heat fine. the supply and return lines are the width of each baseboard. the supply tee is a monoflo tee and the return tee is a standard 1 x 3/4 tee. now here is where the problem starts. there are two bedrooms on the second floor with one baseboard in each bedroom. each baseboard is supplied by a set of 3/4 copper risers from the opposite side of the basement. both sets of risers have a monoflo supply tee and a monoflo return tee ( these are the old style tees with the metal tags on them that say supply and return respectively). neither baseboard gets hot at all. when i bleed each baseboard i get plenty of water, so i know my pressure regulator setting at the standard 12 psi is plenty. this is a new customer. they have lived in the house for 19 years and say they have never had heat in those two bedroom, the use electic space heaters. the other technicians they have used have not been able to correct the problem. would appreciate advice.
