Most people refer to their heating system as a furnace, but that’s a totally different system from a boiler. They both keep you warm, but there are some tips you should know for each. So, do you have a boiler or a furnace?

Do you have a furnace?

A furnace refers to the heating unit in a warm air, or forced air, system. After air is heated in the furnace, a blower forces it through ducts. The warm air is then released through vents or registers in your home.

Do you have a boiler?

If you have a hot water (hydronic) system, water circulates around your boiler’s combustion chamber. A circulator pumps the hot water through pipes to heat baseboards or radiators. Eventually, the water returns to the unit to begin the cycle again. If you have a steam system, the boiler turns the water into steam, which then rises through pipes to radiators.
