How do outside wood burners work?

Outside wood burners, also known as outdoor wood boilers or furnaces, work by burning wood to produce heat, which is then transferred to water or air. The combustion occurs in a firebox, and the generated heat is transferred to a heat exchanger, heating the water. This hot water is circulated through insulated pipes to provide heating for buildings, pools, or hot water systems. They are typically designed to operate efficiently and reduce smoke emissions, making them an alternative heating source for residential or commercial use.
