Using liquid petroleum gas as a fuel source, LPG boilers use an external fuel tank that is connected to feed the boiler. With LPG being denser than regular gas, a substantial quantity can be stored in a relatively small space, making them the ideal solution for homes that do not have access to a mains feed gas supply. Aside from their fuel type, LPG boilers operate in the same way as their natural gas counterparts and are capable of providing central heating and hot water on demand for rural properties alike.
