What is the Most Efficient Temperature to Keep the Boiler At?

Boiler thermostats set the temperature of the water that will be pumped to the radiators. The higher this is set, the more energy will be used and the hotter your radiators will become. As long as you have room thermostats, you can set the boiler thermostat reasonably high to make sure that enough heat is generated.

central boiler:lowering the water temp. | Arboristsite.com

So set at 180 the boiler loop can typically go from a low of 160 to a high of 190. Usually it is more like 165 to 185. Now, subtract 10 degrees for the PEX run and 10-20 degrees from the low for the hot water heat exchanger and you will have typically 145 degree hot water for the hot water and floor loops.

Correct temperature setting for hot water heat/furnace | Terry

Sep 23, 2012 - I have a 2 zone Burham hot water heating system. It is currently set for 180 degrees F, but I notice there is a lot of short cycling. On very cold days the burner will turn on until the water heats up. After that, the zones will cycle the furnace off and on very rapidly- - usually on for a minute, then off, then on, then

What temperature should a central heating boiler be set at

If the boiler is also responsible for generating domestic hot water via an indirect hot water tank (or plate-in-frame heat exchanger, etc.) there should be a sensor on that device that identifies when there is a call for hot water, which would then cause the boiler to increase it's temperature to a setpoint high enough to heat the hot water.

Chapter 2 Boiler 101: typical NYC residential heating system

Hot water boiler If the temperature of the boiler water falls below 180°F, a hot water boiler's controller will initiate combustion. In an oil-burning boiler this is accomplished by a fuel pump drawing the liquid fuel from the storage tank through a filter and pumping it into the burner assembly located in the combustion chamber.
