[Greenbuilding] can anybody help with my hot water heating problems?

[Sam Ewbank]

Benjamin,

Is the boiler firing only when when two zones come on or when another zone
pump besides the main floor pump comes on?
What is the temperature reading of the boiler water when for the main floor
pump is running by itself?
Where you having the problem with the boiler not firing for the main floor
zone prior to the pump being replaced?
Have you checked your wiring connections?
What is your reasoning in thinking you have a  pump going bad?  Similar
service life hours of the one that failed?  Bearing noise?

Opinions worth the price charge

Sam
