Return to page 1 of Boilers

Boilers come in a wide variety of types and power ratings to suit the age and size of a property as well as heating and hot water demands. The bigger the property, the more powerful the boiler must be to supply consistent heating and hot water. Increasingly, boiler efficiency is also a priority, helping homeowners and businesses to minimise energy costs and heat their premises in more environmentally conscious ways. Clients also want reassurance that their boiler of choice is reliable with a long lifespan.

PlumbNation offer many types of boilers to suit the needs and budgets of residential and commercial clients, including conventional boilers, combi boilers, system boilers and electric boilers. Our extensive range includes leading brands such as Worcester Bosch, Vaillant and Baxi. Flues and accessories are also available to complete the installation. Explore our full collection below and find the best boiler for your project.
