Weil Mclain ECO 155 gas piping design question
I am a plumber from the philadelphia area. I have never installed one of these units before. I am installing one in my home and I want to get it right.
I have three heating zones and three circulators.
My old boiler was piped with an 1.5 supply header to 3 loops. Each 3/4 copper to fin tube.
The returns all returned to there own circulator into a 1.5 return header.
Can this eco be piped in the same fashion and is there controls available to handle 3 thermostats and 3 circulators?
Maybe if someone has experience with this situation they could diagram a design for me that works as per manufacturers recommendation. I cannot find anything like it in the manual.
