What is a boiler?01/20/2015 The chilliest months of winter Portland Metro generally find us with more service and repair calls, some of which result in homeowners requiring new heating systems. You can find an array of home heating products on the market, from furnaces to boilers. Many people haven’t heard much about boilers. If you’re one of them, we have some information for you. Types of boilers Boilers are available in both steam and hot water models. Both provide heat throughout a home through either a radiant system that uses a boiler to heat water, or through forced air heating systems. Steam boilers Steam boilers are kind of like big teapots. They boil water until the steam accumulates to create enough pressure to push heat to radiators around your home. The heat is emitted into your rooms by air moving across the radiators. The cycle continues after the steam then cools and condenses to water, which then goes back to the boiler to be reheated. Steam boilers are generally fueled with natural gas or propane. Hot water boilers Like steam boilers, hot water boilers circulate warmth through your home, but with hot water rather than steam. When the water heats up to your desired temperature, it is pushed through the radiant system. Gas is often used to power water boilers, however, you will find oil-fired boilers in New England and the Northeast United States. Benefits of boilers for home heating Many people are partial to boilers because of their very quiet operation. In fact, it’s difficult to hear a boiler operating at all unless there’s a problem with it. They are also known for supplying comfortable and even heat thanks to the design of the system with pipes installed inside the walls or under the floors. Boilers can also be helpful, in non-forced air heating systems, to allergy suffers because they don’t blow air around and spread allergens. Even though they can be more expensive than furnaces, a lot of people find that boilers are a great heating system for them.
