Which term describes a device that heats water to produce steam or hot water in heating systems?

• A. Boiler
• B. Chiller
• C. Heat exchanger
• D. Water heater

Answer: (A)

In heating systems, the device that heats water to produce steam or hot water for distribution throughout the building is called a boiler. A boiler is designed specifically to raise water to high temperatures so it can be used as the heat-transfer medium in space heating via steam or hot-water radiators and loops. A chiller, by contrast, removes heat to provide cooling. A heat exchanger is a component that transfers heat between fluids and isn’t by itself the primary device that generates steam or hot water. A water heater is intended mainly for domestic hot water at taps and showers, not for supplying a heating circuit. So the term that describes a device heating water to make steam or hot water for heating is a boiler.
