In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.Boiler, also called Steam Generator, apparatus designed to convert a liquid to vapour. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect.

All of these have their own set of benefits but are mostly installed in off-grid homes. Gas boilers burn natural gas to heat water that's used for central heating or hot water. This natural gas is delivered to your property, via the gas network, as and when needed by an energy supplier.

The furnace works by burning wood to heat water. The heated water is circulated through insulated underground pipes called insulated pex pipe to the buildings being heated. ... From there it connects to your forced air, in-floor radiant, or indoor boiler heating system and sends the heat around your home.
