What is the correct temp setting for a hot water boiler

If you set your boiler operating temperature below that for extended periods the flue gasses will condense, form acidic deposits and eat the boiler. So one must spend energy to maintain temperatures higher than that. By this it means that your range of setting the boiler down when it gets warmer out is between say, 180 and 140. (Yawn.)

2019-7-19·A condensing boiler can typically increase efficiency by up to 10-12% compared to a conventional boiler. But the gain in effectiveness depends largely on the return water temperature, TR. The lower TR, the better the recovery of latent heat of vaporisation, and hereby better boiler efficiency.

4 things to look out for in steam boiler pressure

Something is wrong with the boiler control. I have to keep pushing the reset button, the frantic school custodian said when I answered the phone one cold January morning. Which control is it? I asked. The one on the boiler, he replied. Please hurry! When I arrived at the chilly school, the custodian pointed to the limit pressure control and I saw it was set for 12 psi.

The boiler temp control - miketheboilerman.com

2019-7-23·If the boiler temperature control is set too low, the hot water cylinder thermostat will never be satisfied and will continuously 'call for heat' (as we say in the trade) so the boiler will continuously cycle ON and OFF. This wastes fuel and heat so paradoxically, for economy it is better to set the boiler temperature control higher than lower.
