Grant Boilers Prices range between £1,100 and £3,010, excluding the cost of installation

Boasting 40 years’ experience in the heating industry, Grant is well-known for designing and manufacturing oil-fired condensing boilers using the best materials and sophisticated technology. Grant has won many prestigious awards over the years and its Vortex oil boiler range has secured Which? Best Buy status. What’s more, Grant boilers are among the most efficient oil boilers on the market and they’ve been endorsed by the Energy Saving Trust, which supports the brand’s claim that its products can save both energy and money.

Grant Combi Boilers Price Range – Ideal for Homes with Low Hot Water Demand

Grant oil-fired combi boilers are space-saving units that heat water on demand, straight from the cold water mains supply. As combi boilers can deliver instant hot water without the need for an additional hot water cylinder, they’re the ideal choice for smaller homes where space is limited and properties with just one bathroom. Grant’s combi boiler range comes in a variety of sizes (kW outputs) and includes units that can be installed indoors or in an outbuilding, so it won’t be difficult to find one to suit your requirements. If you’re interested in buying an oil combi boiler from Grant, you’ll need to spend anything between £2,220 and £3,010.

The current Grant oil-fired combi boiler ranges include the following options:

Grant System Boilers Price Range – Perfect for Homes with Multiple Bathrooms

System boilers don’t require a water tank in the loft but they do need an additional hot water storage cylinder, which is usually housed in an airing cupboard. But as the majority of components are located within system boilers, they are quick and easy to install. Since Grant system boilers can handle multiple taps and showers running at the same time,
they’re suited to homes with more than one bathroom and households with a high demand for hot water. You do, however, need to make sure you have the right size hot water cylinder to meet your household’s needs. If you’re thinking about buying a Grant oil-fired system boiler, you can expect to pay anything between £1,610 and £2,500.

Grant Regular Boilers Price Range – Suitable for Homes with a Traditional Heating System

Often called conventional or heat only boilers, regular boilers require more space than a combi or system boiler because they can only work alongside a separate hot water storage tank, an additional cold water storage tank and a feed and expansion tank. This means that a Grant oil-fired regular boiler can only be installed if you have enough room for a cylinder, as well as space in your loft to put the tanks. A professional engineer will only really ever
recommend a regular boiler for homes that already have a traditional heating and hot water system or for households that tend to run multiple taps, showers or baths at the same time. If you decide to purchase a regular boiler from Grant, it will cost you between £1,350 and £2,600.
