So you are looking for a new oil heating system?

Why choose a Grant oil boiler?

Grant’s Vortex condensing oil boilers vary from traditional boilers since they have been specially planned to capture trapped heat that is normally lost via the flue system while combustion. The Grant Vortex condensing oil boiler, unlike traditional oil-fired boilers, has a built-in stainless steel heat exchanger that uses Grant’s turbulator baffle system and helps cool the gases, enabling the latent heat that’s otherwise lost to be extracted and used in the heating process. This additional energy that’s recovered provides Grant’s Vortex condensing oil boilers with a higher level of efficiency, resulting to better heating, and lover running costs.

Easy maintenance

Another advantage of getting the Grant Vortex condensing oil boiler is that it’s extremely easy to service and maintain. All Grant Vortex Condensing Oil Boilers need to be commissioned when being installed, which ensures that your boiler is operating at peak levels at all times. This, in turn, results to reliability and lowered running costs. The boiler’s ingeniously designed access to both the boiler and the serviceable parts inside makes maintenance hassle free. And if that isn’t enough, Grant also provides a line of outdoor versions of its boiler systems so that it can be fitted neatly and unobtrusively if there is less space within the house.



Reliable guarantee

One of the most sought after features of any boiler or heating system in the UK is its guarantee. Grant boilers are covered by a one year guarantee which can be extended two years if the product is registered with Grant Engineering (UK) Ltd within thirty days of the installation. The Vortex boiler’s 5 year guarantee and the VortexBlue’s 10 year guarantee can only be activated when the boiler is installed by a G-One installer subject to terms and conditions, and is installed according to the specifications of the manufacturer. Home owners are required to get the boiler commissioned after installation and submit the online guarantee registration to Grant Engineering.

Grant oil performance

When it comes to boilers, all installations must comply with British Standards and The Building Regulations. Also, it is advised to get a Grant Mag One magnetic filter installed to prolong the life of your boiler. At the end of the day, the Grant Vortex Condensing Oil Boilers offers you a level of efficiency and reliability that other brands simply do not.
