Are boilers and water heaters the same thing?
“Some homeowners may be unclear on the difference between a boiler and a water heater. There is some crossover in the function boilers and water heaters perform, but these two appliances are not the same. Both appliances heat the water you and your family use, but boilers also provide heat for your home, while water heaters do not.
Let’s start by explaining what a boiler is and the purpose it serves. A boiler provides both hot water and heating for a commercial building or residential home. Focusing on the residential side, that means when you have a boiler, the hot water for your shower, your dishwasher, washing machine and more come from the same source that provides heat for your whole home.
That brings us to one of the major differences between a boiler and a water heater. With a water heater, you would need another means of heating your home, such as a furnace. A boiler not only heats water for use in appliances and showers throughout your home, but uses hot water to warm up your home whenever you turn on the heat during cold months.”

When using a boiler to heat your home, they are generally more efficient than their furnace counterparts. Boilers are also quieter and require less maintenance since there is no air filter to change. However, they are slower to react to temperature changes when adjusting the thermostat.
