I have a towel warmer my wife bought for our bathroom remodeling job. I took my 3/4 inch heating pipes and ran them up and out the wall. When the warmer arrived, it had these valves on them that will constrict the flow to 1/4 inch. I don’t think my heating system will like pumping agaist such a restriction. Are these warmers not made to be put in series like this? Should I just have teed off the existing 3/4 inch line and will I get flow through the warmer if I do this? I’m not happy about this since the pipes are under plaster now. Any suggestions would be appreciated.
If this is the line for your radiators, they are going to like it a lot less than the pump will. And if you just tee’d off the line, you would not get any circulation through the towel warmer. A 3/4 1/2 1/2 inch tee before and after the warmer would give circulation through it, but you would not want the entire heating loop to be on the same circuit.
