A hot water boiler is useful in industrial as well as residential applications. Hot water boilers have applications in various industries, such as textile, medical and food processing. In addition, you can install a hot water boiler to maintain a comfortable temperature inside a residential complex.

If you want to buy, rent or repair a hot water boiler, you will need to be conversant with certain terms that you will hear from the boiler industry professionals. This guide attempts to familiarize you with important key terms, such as hydronics, hard water and AFUE.

Hydronics

Hydronics or hydronic heating is the process of using hot water to transfer heat from one location to another. A hot water boiler is an important component of a hydronic heating system.

Hard water

Hard water contains mineral salts that deposit on the internal surface of boiler components. This affects the performance of a hot water boiler and it is necessary to soften the hard water before passing it through a hot water boiler.

Gauge glass

For the safe operation of a hot water boiler, its water level must be maintained within certain limits. A gauge glass is a glass-enclosed visible indicator of the water level in a boiler.

Boiler controllers

Boiler controllers are electronic devices that monitor and control the system variables, such as steam (or water) temperature and pressure.

Pressure relief valve

A pressure relief valve is an important device for the safe operation of a hot water boiler. These valves operate if the system pressure exceeds the pre-defined pressure value.

BTU (British Thermal Unit)

This is the British unit for measurement of heat. One BTU is the amount of heat needed to raise one pound of water 1°F from a starting point of 39.2°F.

AFUE (Annual Fuel Utilization Efficiency)

AFUE is the unit of heating efficiency of a heating device. To compare different heating devices, you must know their AFUE.
