Stainless steel heat exchanger with innovative hydrolics. The iso valves still turn after 10 years and they never leak. The boiler has various installer programs such as air purge, fault history, status codes and fully explained fault codes.
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.
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.
The Grant Vortex Pro outdoor combination oil boiler features internal frost protection, a 24 litre expansion vessel, neon diagnostic indicators and a factory-fitted condensate trap, together with the conveniently factory-fitted, multi-directional flue - and all of this has been designed to make installation and servicing easier. With larger than normal 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.
Greenstar Oilfit range the easy fit fluing solution. Multiple fluing options with the ability to flue internal floor standing boilers from the top, rear or side and external boilers from the rear and side. The Oilfit range is quick to install thanks to its push fit connection and forms a gas tight seal. In most cases, it will also eliminate the need to cut the flue. The Greenstar Oilfit range provide an easy fit installation that requires no special tools when fitting flue extensions, elbows and adaptors.
