I am planning on relocating an expansion tank from its current very inaccessible location behind the boiler. The new tank is an Amtrol #60 (diaphram 7.6 gallon). It will be typically connected from the bottom of a Spirovent with a TEE to the cold water input. All of this in on the intake side of the system circulator. Pumping away applies. My question: It there a minimum or maximum distance for the expansion tank location from the air eliminator or boiler. Based only on physical ease ideally the expansion tank would be about 4 feet away. I have never seen this and wonder if it is acceptable.

This is all I know so far. One zone small Dutch colonial 2 story. I thought this would be steam she is telling me it is Hot Water. Heading over to check things out in the next week. The furnace was recently replaced within the past few years, I would of thought a good provider would of installed a second zone? She claims by being comfortable downstairs its way too hot upstairs.? FYI: Domestic HOT Water is a separate unit. What if any quick fix can be done to possibly reduce heat upstairs.
