Splet25. nov. 2024 · A boiler that’s cycling too frequently (short cycling) is often the result of high pressure. A boiler’s pressure should never go any higher than 3 bar (about 30 PSI). So when the pressure builds to an unsafe level, the boiler will automatically shut down—which means, you guessed it, a shorter cycle.

SpletThe 00 ® Series Variable Speed Outdoor Reset Circulator controls the hot water supply temperature, so that the heat supplied to the building equals the heat loss of the building.
