It is very important to check whether the domestic water heaters and the boilers work and operate safely and efficiently in the commercial and institutional facilities. Today, the control system and the designs of the units have becomes much safer and efficient than it was at earlier times.

Efficiency and safety cannot be guaranteed just by good design. With good system designs, testing programs and an ongoing inspection must be carried by professionals who should be structured and safe in operation. The engineering managers and the maintenance persons who ignore any of these basic elements, they not only risk efficiency and safety but also the equipment operations.

3 Important Safety Devices

All the domestic water heaters and the boilers have special built-in equipment that makes sure the device is operated safely. Just like the building mechanical systems, they too demand maintenance periodically to ensure the smooth operation of the system. The technicians and the boiler operators must make sure they closely attend to the three main safety devices to save the equipment, personnel, and the facility.

• Safety Valves- A Major Safety Device

It is the most important part of the safety device in the domestic hot water system and the boiler. It has been specially designed so that it takes out the internal pressure if a failure is witnessed inside the system. The design of the Safety Valve is simple and straightforward but the operation can be affected just by a restricted flow or the corrosion.

• Water-Level Control and Low Water Fuel Cut Off

In most of the systems, these two safety boilers are functioned in a single unit. It is designed to make sure the water level does not fall below the fixed mark. If it falls below that, the system will automatically shut off. One should make sure that no sludge build-up or scale prevails in the system.

• Water-Gauge Glass

The operators must make sure that the water level in the system is right. The building of scale or sludge may result in a false indication level.
