There is no "vacuum in the system". The plumber was just giving you a fancy explanation for a simple adjustment. WIthout access to the unit we cannot tell if it is a circualtion or control problem. Most other plumbers should be able to check it and find the problem, if they are familiar with indirect water heaters.
: I did a looking at our "water heater", and a little research on the web, found out that we don't actually have a conventional water heater, we've got an indirect water heater, an "Amtrol Boilermate - Model "WH-7" which gets rave reviews on every website I've visited. I get the impression that it's probably fine, there's just another problem somewhere in the system, maybe the thermostat is shot or something...
: The actual problem is kinda odd... I played with valves in the boiler-room, drained 3-4 gallons of HOT water out of the boiler(to be expected, I suppose) and we had hot water the next morning, and for about 3 days afterwards. Our hot water is again not hot, it's not even very warm, it's just not as cold as the water coming out of the cold water tap, and it doesn't last very long.. kinda makes me think that the water that is warm is just warm because it's near warm water somewhere in the system and is getting heated by proximity to other hot water, instead of on purpose.
: I'm grasping at straws here, but I'm outta ideas.. should I replace the thermostat on the Boilermate, check (and how to check?) for "vacuum in our system", or replace the Boilermate itself?
: Thanks for any help,
