Conventional Oil Boilers

A source of heating is an essential part of life and in today's modern world, there are numerous ways in which to provide it. Many British homes are powered through gas central heating systems, but that doesn't have to be the only choice. Oil boilers simply require oil, heating the water system by burning the oil inside.

Heat and Plumb offers a large selection of oil boilers from some of the world's most respected boiler manufacturers, including Firebird, Warmflow, and Worcester. Whether you require an external or internal oil boiler, wall hung or floor standing, or even a boiler house - there's a model here for you.
