I see a ton of aquastat questions posted here but I cant seem to figure it out. I understand the high and low limit thing, but what exactly does the differential do?
I have a boiler with a tankless coil (My boiler makes my hot water) what should the differential be set at? The boiler seems to be cycling too often set at 15, with no call for heat or hot water.
The temp gauge on my boiler must be off because if i set my aquastat at 180/160 the boiler gets 200 degrees plus.
and a totaly different question...I just installed a second zone on my boiler for my new second story, and without the circulator being on the pipes and baseboard on the second floor seem to always be hot. i put a brand new flow valve and circulator on this zone...I dont get it, it doesnt happen on the first floor.
Any help would be greatly appreciated.
