Vortex Blue: Internal Combi

The Grant VortexBlue Internal Combi range combines Grant’s award-winning, patented stainless steel heat exchanger with the latest Riello RDB BLU compact burner.

Three white cased models are available in the Grant VortexBlue Internal Combi boiler range, all featuring large heat exchangers which have low water content and a larger surface area, greatly increasing the hot water performance. Each VortexBlue Combi is supplied with a 24ltr expansion vessel as standard and with front access, these boilers have been designed with the installer and servicing engineer in mind.
