Back Boilers with Gas Fires: Out of Use or Still on T

Back boilers with gas fires were initially created in late 1960s and were extremely popular within 20 years after the very first appearance on the market.. Being hidden behind a chimney with a gas fire in front, such units provide pretty effective heating. They are usually made from cast iron, and they are a legacy, since the time the water was heated by a coal fire.
