Gas central heating – pros
Gas is a highly efficient fuel, so you get a good return on each unit of energy. Modern condensing boilers that use hot flue gases that are consumed in a standard boiler have a very high efficiency – ~ 90% or more effective.
Gas is supplied directly to your home, so you do not need to store fuel. Replacing a standard gas boiler with a highly efficient modern condensing boiler is relatively simple.
Since gas is the most widely used fuel for heating in the UK, finding a heating plumber in the Gas Safe Register should be fairly easy if your boiler is broken or needs maintenance.
