Are made in the UK by Grant and are recognised as one of the best central heating diesel boilers in the world.
Grant produces the most efficient boilers currently available on the market. Independent testing laboratory SEDBUK tests all boilers and Grant has a large majority of boilers on their top 100 list. Most boilers run at 70-80% efficiency, but Grant's new generation condensing boilers deliver efficiency levels of up to 97% and all feature the ‘award winning’ unique Grant Vortex stainless steel condensing heat exchanger, and turbulator baffle system.
We offer both indoor and outdoor models with a variety of output options to suit the size/scale of your home. You can also choose between a standard or combination boiler, which in addition to heating your home, also provides instant domestic hot water.
