Boiler Safety

Boiler Safety

The safe and efficient operation of boilers and domestic water heaters is necessary for the operation of most residential and commercial facilities. Improvements in designs and control systems have made modern units safer and more efficient than before.

But there are other factors to consider to ensure safety and efficiency. In addition to a well designed system, scheduled inspections and testing done by a technician or service professional could keep your boiler running safely and efficiently.

Safety Devices

All boilers and domestic water heaters have a variety of built-in devices to help ensure their safe operation. Like other components of major appliances, they require scheduled maintenance to make sure they’re operating properly. Boiler technicians and professionals pay close attention to three key safety devices to protect the safe operation of your home’s boiler:

Safety valves. The safety valve is the most important safety device in a boiler or domestic hot-water system. It is designed to relieve internal pressure if a range of failures occur within the system. Although it is simple in design and straightforward in operation, something as minor as corroded or restricted flow inside of the valve and its related piping can affect the overall operation.

Water-level control and low-water fuel cutoff. Many systems combine these two separate boiler-safety functions into one unit. They’re designed to make sure the water level inside of the boiler never falls below a certain amount. If that ever happens, the system is designed to shut down the boiler by cutting off its fuel. Proper functioning requires operators to make sure there is no build-up of sludge or debris within the system that would interfere with its detection and operation.

Water-gauge glass. Even with a functioning water-level-control system, it’s important for your service professional to verify the actual level of water in the system. Here, too, a build-up of sludge and debris can give false level indications.
