View ProductsBehind every Grant Vortex oil boiler in today’s range is over 40 years of experience in designing and manufacturing reliable and efficient oil-fired boilers. With their incredible efficiencies and incorporating the latest burner technology, all Vortex oil boilers have been developed to provide householders with a warm, comfortable home efficiently and effectively.
The range delivers choice and flexibility when it comes to installation. From smaller boilers suitable for compact homes, external boilers for homes where internal space is at a premium through to larger boiler installations for bigger properties, the Vortex range comprises of oil boilers ranging in output from 15kW up to 70kW with heat only and combination boilers available.
As well as being energy efficient oil boilers, the Vortex floor standing boilers are also HVO compatible which means they can be converted to HVO operation with a few alterations. HVO biofuel is a low carbon liquid fuel which could play a significant role in helping off-gas, rural properties to transition to more sustainable home heating in the future so by choosing a Grant Vortex boiler, homeowners could make the switch from kerosene oil to biofuel with ease.

An oil boiler works in a very similar way to a gas boiler. They comprise of several key components that include a pressure jet burner, a combustion chamber, a water jacket containing both a primary and secondary condensing heat exchanger and a flue system to safely remove the unwanted combustion gases that are produced by the boiler. Oil boilers also need their own fuel supply which will require an oil tank to be installed at the property. Oil boilers generally use kerosene as their primary fuel source but with an ever increasing demand for more sustainable home heating the introduction of biofuels such as HVO is well underway. The fuel used is ignited within the combustion chamber by the pressure jet burner. As the hot combustion gasses rise up through the heat exchangers, they heat the surrounding water within the boiler, and the heated water is then used to heat both the emitters, such as radiators and underfloor heating, and the domestic hot water within the property. Once the combustion gases have passed through the boiler they will enter and pass through the flue system and disperse safely outside of the property.
Oil boilers are categorised as either heat-only boilers, which provide heat into both the space heating and domestic hot water system and require a cylinder to supply the hot water to the property. Or a combination boiler (combi) which provides both heating and hot water direct from the appliance and do not require an additional cylinder. Both are usually available as both internal and external models.
Grant Vortex boilers are condensing oil-fired boilers – please click here to read more about how condensing boiler technology works.
A condensing boiler has second (condensing) heat exchanger where the flue gases are cooled to below their dew point by the water returning from the heating system. This has the effect of condensing the water vapour present in the flue gases, and liberating the heat energy that would otherwise be lost to outside through the flue system.
