What are Gas Boilers? 

Gas Boilers produce hot water and heat the home, like mini fires. These central heating systems continuously heat water, pump it through pipes and radiators, spreading heat around the property to heat the house. The hot water is either pumped to taps and showers directly, like in the combi boiler or stored for future use in a water tank. The boiler works on either bulk LPG, stored on-site, or on the on-grid gas. This gas is then burned in the boiler’s combustion chamber that raises the water temperature to around 70°C using a heat exchanger.
