System circulated position with a mod/con
First of all high everyone.
I have visited your post many times and have a question I don't seem to be able to find an answer for. I am retrofitting an old oil boiler system with a mod/con and my current zone pumps are on the return lines. All the pipe plans I have been looking at show the system or zone circulators on the supply upstream of the boiler. I need to know if I will need to change this config or if it will be ok as is. The current system's supply and return pipe directly to and from the boiler. I will be adding a Low loss header with the new boiler and am concerned about how the position of the pumps may affect the header flow. I will be greatful for any help. I have read a lot of posts on this site and you guys seam to know what you are talking about
