Oil Combi Boilers

Heating your household and hot water with an oil combination boiler is a great alternative for those rural properties that do not have a mains gas supply. In similar fashion to a gas combi, combination oil boilers do not require a hot water cylinder creating more indoor space, something that is sought after for modern day living. As well as internal units, external oil combi boilers are another fantastic option for freeing up space. With a durable weather proof casing, external oil combi boilers are fully protected from the elements and can be controlled via an indoor programmer from the comfort of your home. We offer a fine selection of oil combination boilers from the top brands, including Worcester, Grant, Firebird and Warmflow.
