I have a 56-yr-old, gas-fired, hot-water boiler that works fine. I set the boiler aquastat manually, depending on outside temp and wind.
During fall and spring, or during warm spells during the winter, I set the aquastat at about 145 deg. During winter cold spells, I raise it to 160 deg. In either case, the burner cycles - although in bitterly cold weather with wind, the cycle time lengthens considerably.
Does this sound about right? Any comments or suggestions? Thanks.
