The range of grant boilers available at PlumbProud

Grant Engineering, better known as Grant boilers, was established in 1978 and it quickly became known for its range of oil fired back boilers. In 1990, now called Grant UK, the company embarked on its current path which would lead it to become Britain’s most respected and innovative manufacturer of energy efficient, low maintenance, and cost-effective oil boiler solutions.

They were the first company to launch a condensing oil boiler, years before other manufacturers would be required to follow suit by law. In 2006, they launched their own range of solar thermal panels, special types of panel designed not to generate electricity from the sun but to provide heating and hot water. And in 2010, they launched their first generation of air heat pumps.

Their oil boilers have been endorsed by the Energy Saving Trust for 15 years. At the recent Heating and Renewables Awards, the company won the Innovation of the Year category with its Vecta biomass boiler.

We’re proud to offer our customers the full range of Grant’s oil-fired condensing boilers. Whether you want a combi boiler, system boiler, or heat only boiler, let one of our engineers visit you so they can find out what you want, make the best recommendations, and leave you with a competitive quote

Grant combi boilers

Best suited to smaller properties with one bathroom, Grant combi boilers draw water directly from the mains supply heating it on demand whenever you want to warm your radiators or switch on a hot top.

Please click here for our range of Grant combi boilers.

Grant system boilers

The insulation cylinder on Grant system boilers provides piping hot water to multiple points at the same time within your home with no loss of water pressure. Very energy efficient and easy to use.

Please click here for our range of Grant system boilers.

Grant heat only boilers

Grant heat only boilers are ideal for larger properties with multiple bathrooms and a high number of radiators. Best for families where many people need to use hot water at the same time of day.

Why are the Plumbproud scores for Grant boilers so low given how good a brand they are?

Grant oil boilers are appreciated and respected by installers and customers alike. The Vortex Pro is a particularly impressive range of oil boilers as is the Vortex Eco range.

Given the choice however, most homeowners would choose a gas boiler. The main reason why households choose oil fired boilers is because they’re not yet connected to the Gas Grid.

The Plumbproud scoring system is based upon the feedback given to us over 10,000s of appointments with homeowners who have shared with us what they want from their boiler. Two of the main considerations are price (oil is more expensive than gas) and environmental concerns (many argue that using oil to heat a home causes more damage although this opinion is not universally shared).

The heating products manufactured by Grant Engineering are fine pieces of modern technology and we would thoroughly recommend them. Think we should come up with a separate oil boiler scoring system? Get in touch and let us know.
