Outdoor Boilers33
An outdoor boiler (commonly called an outdoor wood boiler, outdoor wood furnace, or hydronic heater) is a wood-fired heating system installed outside the home—typically resembling a small shed with a smokestack—that burns logs or other biomass fuels in a firebox to heat water contained in a surrounding water jacket. The heated water (or water-antifreeze mixture) is then pumped through insulated underground pipes to transfer heat indoors via heat exchangers connected to forced-air ducts, radiant floor systems, baseboards, radiators, or even pools, garages, and outbuildings, keeping smoke, ash, and fire risks away from living spaces while providing an efficient, renewable heating alternative in colder climates.
Modern designs often incorporate gasification technology for cleaner, more efficient combustion compared to older models.
