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.
