The Hartford Loop - Steam Boilers. The Hartford Loop is a requirement on all steam boilers for safety. It is a section of piping on your steam boiler that connects the condensate return piping to the steam boiler header on gravity fed returns. This equalizes the pressure between the return and the steam supply.
For steam boilers, a daily test of the low-water fuel cutoff device is recommended by CSD-1, which also recommends performing a semiannual slow drain test of the low-water fuel cutoff device. Performing a slow drain test requires caution as the primary low-water fuel cutoff must be jumpered to allow the burner to continue firing after the water level is lowered below the primary low-water fuel cutoff.
boiler equipment requires review of boiler type, feature and benefit comparison, maintenance requirements and fuel usage requirements. Of these evaluation criteria, a key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler
The newer steam boilers hold only 5 or 10 gallons of water, which quickly heats and delivers heat to the sections of radiators that need it. The room thermostat senses enough heat long before the last sections get hot, and stops the burner from heating that small amount of water.
For this reason, many steam boilers have a low water cut-off valve that senses when water levels are dangerously low and turns off the burner beneath the boiler. If the boiler ran low on water, was refilled, but the burner will not turn back on, it is likely the low water cut-off valve needs to be reset.
