In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I am new to this forum, but I would appreciate very much some guidance and feedback. I am installing a new Peerless WBV-04 hot water boiler this year and would like to know the best location to install the circulator, on the feed or return side. Our existing layout has the circulator installed on the return side; however I have read that it is better on the feed side – after the expansion tank.
Also, I will install a new expansion tank and I would like a suggestion regarding the type. I have always used an actual cylindrical tank for the expansion tank and this has worked well. I have read about the bladder-type expansion tanks, but I am not sure if this is the right type.
The piping plan for the feed side I have come up with is a 1.25” pipe from the boiler to a LWCO sensor and then to a 90 degree elbow and then a Watts Micro Bubbler, then the circulator (with isolation valves), after the circulator reduce piping to ¾” to feed 2 TACO zone valves. I would attach the expansion tank to the bottom of the Micro Bubbler.
The piping plan for the return side would be 2, 3/4” return lines back to the boiler, then a boiler drain valve w/isolation valve for purging, then gradually increasing pipe size up to 1.25” to meet the boiler.
