Reasonable head loss on series loop
Hi. Not sure this should be in radiant or not, but I didn’t see a “hydronic” section. What is a reasonable head loss for a series of 3/4” pex with 6 baseboard units in series? Based on gpm (0.8) and pump size (1/25 hp taco) and my independent pressure gauge measurements, the non-boiler (loop) head losses are on the order of 5-7 feet, giving 3/4” equivalent length of 1150 feet (includes elbows etc) This seems incredibly high for a loop that is heating a ~1000 sqft place. Trying to figure out if there is a construction somewhere before it gets dry walled up.
