I’ve read form other posts on this site that when replacing an old boiler that the new boiler model isn’t necessarily as important as is the installation. I’ve settled on a Burnham MPO147. I have a plumber bidding on the project with 15 years plumbing and heating experience. He’s installed approximately 25 Burnhams and 8 of those have been MPOs.
Is that enough experience so that he should know how to properly install my MPO?
