Recently moved into a home that has an oil boiler which provides hot water for baseboard heating and an indirect hot water tank. I just had a plumber/hvac guy out to replace the expansion tank and he noticed the Honeywell high/low setting which is currently set at 180/160 with a diff of 10. He said the low was set too high and put it at 120. I researched and that seems way too low for an oil boiler, but I’m not an expert. Does anyone know what the best settings would be for my system? It’s a peerless boiler from 1989. My concern is that 120 will cause condensation
