Boiler
A boiler is a heating device that converts water into steam or hot water, which is then circulated through a building for heating or used in steam-based processes. Boilers can run on natural gas, oil, electricity, or biomass, and modern high-efficiency models reduce energy use when properly sized and maintained. Efficiency is often measured by AFUE (Annual Fuel Utilization Efficiency).

FAQ
What’s the difference between a boiler and a furnace?
A boiler heats water or steam for radiant or hydronic systems, while a furnace heats air and distributes it through ductwork.
How long do boilers last?
Many boilers last 15 to 25 years with proper maintenance, depending on fuel type and usage.
Are boilers energy efficient?
Modern condensing boilers can be very efficient, especially when matched to the right system and properly maintained.
