Vortex Pro External Combi Condensing Range

The up to the minute electronic Grant Vortex Combi Range includes internal frost protection, neon diagnostic indicators and a factory fitted internal condensate trap (this can be fitted externally if preferred), which is designed to make installation and servicing easier.

The external combis also feature a multi-directional factory fitted low level flue, external powder coated robust casing, built-in frost protection, a mains isolating switch and a test switch.

The Grant Vortex Pro External Condensing Combi’s come in three sizes, 21kW, 26kW and 36kW.


UNIQUE DESIGNS

Grant Vortex Pro Combi’s have larger plate heat exchangers which due to their low water content and great surface area, vastly increase hot water performance. Mixing valves on the unit are pre-set at 50°C, which accurately control the hot water draw off temperature from the boiler. They also include a low system pressure cut off switch, enabling the combi to protect itself in the event of system water loss. Additionally, there are two very intelligent electronic temperature controls which allow the boiler to operate in condensing mode on central heating, whilst keeping the instant production of hot water.
