10 Things to Know About Boilers | Boiler Expert Minneapolis
Mar 16, 2016 · Boilers provide radiant heat, which warms objects in a room. In contrast, a forced-air furnace warms the air in a room, which means objects absorb heat more slowly. Some people prefer boilers because they can set their thermostat at a lower temperature and the radiant heat makes the room feel warmer than the actual air temperature.

Part 1 - National Board of Boiler and Pressure Vessel
Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.

How to set and adjust the boiler pressure control?
Feb 26, 2019 · Once the pressure reaches your set point, 10 Psig, the burner shuts off. The burner stays off until the pressure inside the boiler drops to the differential (2 psi) setting minus the setpoint. In theory, our boiler will cycle between 8 and 10 psig. The following controls fall under the subtractive type of pressure …

What to do if your boiler loses pressure - British Gas
The position set when the boiler was installed is sometimes shown by a red indicator needle. On most digital gauges, you'll see a flashing pressure reading, if there's a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, it's possible that you might have lost water from the system, which needs to be replaced.

What Should The Boiler Pressure Be When The Heating Is On?
When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.

Plant Engineering | Maintaining boiler safety
Low-water trips protect boiler pressure parts by shutting down the fuel combustion process, eliminating high temperatures in the furnace when the natural circulation cooling process is interrupted. Control of the boiler drum level is sophisticated, and even the best-tuned control systems cannot always prevent a low-water condition.
