The Grant Boiler Range

Oil boilers don’t burn the cleanest fuel, nor is oil the most energy efficient fuel that a boiler can use.  But it is a necessary one if you aren’t connected to the gas grid.  This is where Grant boilers excel.

Grant Boilers use blue flame technology, which signifies much cleaner combustion happening in your boiler compared to the standard yellow flame most boilers use.  Their boilers are also incredibly energy efficient and produce low amounts of NOx pollutant emissions.

This means that when you choose a Grant boiler you are doing the best you can to not only look after your wallet, but the environment as well, which isn’t always something that can be said for an oil-fired boiler.

Grant also offer a range of sizes and types of boilers, encompassing combi, system and regular boilers to make sure they have all bases covered when it comes to their offering, so there should be something in their range for everyone who is looking to replace their oil boiler.

They even have units that can be wall mounted, as well as internal and external oil boilers as well, to offer even more options for more homes.

Grant are reasonably priced when it comes to oil-fired boilers.  When it comes to price there are a lot of factors that determine how much a new or replacement boiler will cost.
