Down-Rating Boiler for Mouat
I have encountered a grossly oversized boiler (must have been sized by radiator survey not taking into account the system's using larger radiators) on a Mouat system. I'm planning on having a boiler specialist come to crank it down as much as possible to get it to simmer for the Mouat system's peculiar needs, but am concerned that in some cases a boiler installer may not want to, for fear of voiding the manufacturer's warranty. This boiler is a Utica JE, but my question is not brand-specific. Your thoughts (especially you Cleveland guys).
