Hi all,
I'm reviving this one because our AC/heat pump company came to take a look while they were doing spring start up on that system last week. they said leaving the coil in is perfectly acceptable but that it would be better to close both hot out of coil and cold coming in and I shouldn't need to worry about any boil off or anything (the tech said his mother has had the same setup for 15 years after she added an amtrol tank to the system).
He did say however that it was silly to have the boiler running when nothing needs it and recommended changing the aquastat (mentioned a honeywell 8148A) and setting it up for cold start so that unless a zone (hot water baseboard or hot water amtrol tank) is calling for it, the boiler won't run at all.
Based on feedback, it sounds like some of you might not agree with the first part (leaving the coil in) but would agree with the cold start of the boiler, right? Is there anything so bad with this proposed setup?
One thing I don't get is let's say that the boilermate dies one day. I can close the valves to/from the boilermate off, and open the ones to/from the coil, but since potable hot water isn't a zone (unless it's coming from the boilermate), then I don't think the coil will make hot water in a cold start setup because there won't be a zone calling to turn it on, right?
