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.
