Gas-Fired Boilers and Furnaces | Department of Energy

A time delay relay is a way to squeeze the most heat out of your system without running the boiler. When the thermostat clicks on, the relay causes the boiler to circulate hot water through the system without turning on the boiler. After a set time, the boiler will fire up. A time delay relay costs about $100 and can cut your fuel costs by up
