Oil System Boilers

System oil boilers are a perfect alternative for properties in areas without a mains gas supply. Including a built-in circulating pump and expansion vessel, there is no requirement for a gravity fed water tank to be located in the loft, thus creating more space, ideal for modern day living. When installed with a hot water cylinder, oil system boilers provide a heat source for your central heating and hot water needs, making it suitable for larger properties with multiple showers or bathrooms. With a wide range of leading brands to choose from, PlumbNation has you covered whether you're replacing an existing system or ready for a new installation.
