In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I recently replaced my old Burnham 100k Holiday with a new Carrier BWB70k. The install went fine, chimney liner, expansion, etc... The house is 1200 sq ft ranch with single 1-1/4" loop, no zones. The 9" base rays are on single parallel loops off the 1-1/4" via 3/4".
Pressure set to 10psi cold being its a ranch. The system runs fine, heats well, BUT I got a loud 'resonance' sound in the far end of the house (where the bedrooms are of course).
The sound is similar to when the wash machine fills up and I am upstairs... It just sounds like water rushing in a pipe. I've worked with the installer, moved some basement ceiling tikes, tried pushing/holding the loop, nothing changes the sound until the pump stops.
My question, should I try a taco 005 instead of the 007 that's on there now?
Also to clarify: the setup is boiler-expansion tank/air vent- taco pump- and then onto the loop. The taco pump is vertical, pump hanging under the pipe.
The old system was a 1/6hp B&G and the house was SILENT.
any help is appreciated,
