troubleshooting a gas-fired hot water boiler

Troubleshooting a Gas-Fired Hot Water Boiler

The boiler doesn't have power: The circuit breaker or fuse controlling the furnace may have tripped or blown. Reset the tripped circuit breaker or replace a blown fuse. The water level is low: Maintain the water level in the boiler at half-full.The boiler's automatic filling system, controlled by the pressure-reducing valve, should maintain the proper water level at 12 to 15 psi of pressure.

what is the correct temp setting for a hot water boiler

What is the correct temp setting for a hot water boiler

Your boiler is a block of iron that wants to remain warmer than the spent flue gasses (140F for gas, maybe 130F for oil). Let's call it 140 to be safe. If you set your boiler operating temperature below that for extended periods the flue gasses will condense, form acidic deposits and eat the boiler.

relationship of design pressure, test pressure & psv set point

Relationship of Design Pressure, Test Pressure & PSV Set Point

PSV-1 has a set point of 180 psig. This was determined by adding a safety factor of 30 to the 150 psig desired steam operating pressure downstream of the PRV. The design temperature for the 150 psig steam line will be the correlated saturated steam temperature at 180 psig, or 380°F.

Boiler Temperature Set Points For Residential Baseboard

Feb 04, 2019· I set the on temp around 180 degrees and it shuts down whenever the thermostat clicks off. The boiler easily keeps up even when the temps are down around -35 to -40 outside. The gauge shows around that 180 degrees. For its age, the old boiler seems to be very efficient as my normal heating bill in Winter runs around $40 a month.
