Definitions - Central Boiler
Conduction A process of heat transfer whereby heat moves through a material or between two materials that are in direct contact with each other. Convection The transfer of heat by movement of a liquid or a gas. Natural Convection is a result of movement caused by changes in density as temperature changes within a fluid medium such as a liquid ...

Central Boiler Installation and Initial Water Treatment Guide
centralboiler.com• ThermoPEX pre-insulated piping is recommended for all installations. Other types of insulated pipe configurations may result in high heat loss and increased wood consumption. • If the ground at the location is unstable or subject to frost ... 4 Central …
Hydronic Fan Convectors - Central Boiler
centralboiler.comFan convectors work efficiently with hot water heating systems regardless of whether they are connected to a typical boiler or renewable technology such as a Central Boiler outdoor wood furnace. Hot water from the central heating system passes through a heat exchanger and transfers its heat to the aluminum fins where the quiet
