My current Operating Limit aquastat is set at 180 degrees with a 20 degree differential. Would I gain or lose efficiency by setting it to 190? I guess the rooms would heat up a bit quicker and the room thermostats would stop calling for heat sooner but then wouldn't the boiler run more often due to it's own heat loss?
How about just the opposite and reducing the Operating Limit to 170? In my feable mind I can reason that each has it's advantages(at 170 boiler stops burning sooner but circs run longer and then possible "restarting" the boiler again?).
