The Boiler House - A Basic Overview of A Steam System -
Definition of BoilerThe pressuretrol cycles the boiler on and off as it is making steam. Pressure in a residential steam boiler should never build more than 2 psi, if it does the system won't heat the radiators. As long as your thermostat is telling the boiler it needs heat, the boiler simply cycles on and off by steam pressure and continues to heat the radiators.

THE PRODUCT: Boilers heat water that is then used to heat a home using a hot water or steam distribution system. The technology used for steam boilers is the same as for hot-water boilers, except that circulating pumps are not used in steam boilers. Boiler capacities range greatly, but they tend to be higher than furnace capacities.
