How Are Boilers an HVAC System?

It’s winter again in Des Moines. The frostiest months of winter tend to bring about more service and repair calls, which often results in the need for new heating systems. From furnaces to boilers, there are various products on the market that will heat your home. What’s a boiler you ask? Let’s explore.

Types of Boilers

A boiler is a type of HVAC equipment used to heat your home, and it takes either steam or hot water to do so. Both use a boiler to heat the water and a radiant system to provide heat to every room in a home.

Steam Boilers

You could compare steam boilers to a teapot. These systems boil water to make steam, which is transported to radiators all over your home. Creating more steam amplifies the pressure in the system and pushes the steam throughout the system. Radiators have air vents that open to let off the pressure – and the heat – into your rooms. The steam then cools, condenses to water and returns to the boiler to be reheated. Steam boilers are usually powered with natural gas or propane.

Hot Water Boilers

Hot water boilers operate similarly but circulate hot water throughout your home instead of steam. When you boost the heat, water begins to warm up and is transported through the radiant system when it has met your chosen temperature. Water boilers can be fueled using either oil or gas, however, oil-fired boilers are not commonly found outside of New England and the Northeast U.S.

Benefits of Using a Boiler

Boilers are known for their almost soundless operation. In fact, you more than likely won’t hear a boiler running at all unless there’s something wrong with the system. And, because radiant systems use pipes that are installed in the walls or floor, boilers can provide a more comfortable and even heat. Another benefit is that boilers don’t blow air around, helping decrease the allergens in the air.

Selecting the right heating system for your home can be a hard decision. Although they can be more expensive than furnaces, boilers offer quieter and more even heating for your home.
