We all know that furnaces and boilers are used for heating our houses. However, many people do not know the difference between these two types of heating devices. Even homeowners can confuse them.
Generally, to heat homes a furnace uses warm air, boiler uses hot water. To heat air a furnace uses the electricity or natural gas. Then warm air is distributed throughout the house.
Boilers heat water or make steam. Water or steam travels through pipes to radiators that are used for heating purposes. Optionally, steam can be used to heat a fan coil unit which then heats circulating air.
Major parts of boiler are tank and water heater. Heater uses electricity or natural gas (also it can be heating oil) to heat the water. Cold water enters to the tank and pushes the already heated water out through another pipe. In a steam system, the boiler turns the water into steam.
Normally, the purpose of a water boiler is to heat a house. Additionally, houses have a water heater to heat water for washing and bathing although there are combination or combi boilers that combine the central heating with hot water in one box. Any boiler, furnace, or heater is a complicated system which consists of many parts, including controls and safety devices.
All heating system products should be repaired and installed by licensed and certified technicians. If you need a help with heating, furnace, or boiler (or have questions), call 604-437-7272. More info about heating…
