On the other hand, I see a lot of decades-old Burnham Series 2 boilers, including newer variations like the ES2 and the Series 3……….

Re: Is the circulator pump too powerful?

The Taco pump for the 3rd floor has an internal flow check which is stuck open or has some debris in it. It’s in (or should be) the discharge side of the pump. Fix that and your problem will be resolved.

Re: do you really need a thermal expansion tank

If there is any form of check or non-return valve on that domestic system, then yes you need an expansion tank on the hot water, unless there is a well pressure tank AFTER the check or non-return valve.

Don't debate the issue — just do it.

Re: do you really need a thermal expansion tank

Hi, I'm thinking it's more of a "what if" or "worst case" scenario. Ed is right than essentially nobody checks the T&P yearly, and that could be a big liability to take on. But, the more obvious problem usually is thermal expansion. Water just gets bigger as it's heated. Where will that extra water go?
