Vortex Pro External Combi
The intelligent Vortex Pro Combi incorporates the latest Riello RDB low NOx burner technology and combines it with our award winning Vortex stainless steel heat exchanger.
The Grant Vortex Pro Combi features large heat exchangers which, due to their low water content and larger surface area, vastly increased the hot water performance. With a low system pressure cut off switch, the combi protects itself in the unlikely event of system water loss. Additionally, there are two very accurate electronic temperature controls which allow the boiler to operate in condensing mode on central heating whilst maintaining its instant hot water production.
