I recommend this to all engineers.
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.

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.
