The award winning Grant Vortex Kitchen boiler range has over the last few years become the market leader in oil-fired condensing boilers, achieving gross seasonal efficiencies of between 94-95% gross.
In 2003, the boiler was voted ‘H&V Product Of The Year’ and has quickly become popular with both heating engineers and householders, setting the standard for oil-fired condensing boiler design.
As you would expect from a product with this pedigree, the Grant Vortex kitchen range is exceptionally quiet in operation, featuring the latest Riello burner technology. All models incorporate system diagnostics enabling easier setting and control of both the temperature and general operation of the boiler.
Sealed System Models
All sealed versions include a factory fitted expansion vessel, fitting loop, pressure gauge, automatic air vent, pressure relief valve and circulating pump, enabling boilers to be installed without the need for an expansion tank in the loft.
Programmer Option
A simple electronic programmer option is also available which can be plugged into a pre wired slot on the boilers control panel.
