The latest Grant Vortex Pro internal combination oil boiler features a 24 litre expansion vessel, neon diagnostic indicators and a factory-fitted condensate trap - all designed to make installation and servicing easier. With larger than normal plate heat exchangers, the hot water performance of this high-efficiency combi boiler is vastly increased. The two very accurate electronic temperature controls allow the boiler to operate in condensing mode on central heating and instant hot water production can be maintained. In addition, a low system pressure cut off switch protects the combi boiler in the event of system water loss.
Built on all the tried, tested and much-loved features of the Greenstar i, the Greenstar 4000 is instantly familiar and yet totally transformed in appearance, performance and installer plus points. We’ve raised the bar with the speed and ease of installation, commissioning and servicing, alongside improvements in efficiency and control.
Innovative design features ensure the Worcester Keyless Filling Link delivers reliable, trouble-free performance without risking backflow or overfilling.

Created by Grant, this Vertical Balanced Flue Kit provides a comprehensive flue system which will exit through either a pitched or flat roof. The unique clamping system on the vertical balanced flue ensures easy assembly thereby reducing installation times. Vertical balanced flues can be extended to a maximum length of 6 m on non-condensing boilers and 12 m on condensing boilers in a straight run using extension kits. Made from a robust, anti-corrosive stainless steel, the kit will provide a strong, long lasting system that perform efficiently for the life of the boiler.
