Gas central heating boilers and furnaces - How d

A few hundred years ago, people would have given an arm and a leg to have central heating in their homes. Just imagine the inconvenience of having to light a wood and coal fire in every separate room to keep your house warm. The basic idea of central heating is really simple: you have a boiler (an easily controllable furnace, fueled by gas) in a handy place like your kitchen or bathroom and it
