The latest Grant Vortex Combi models feature internal frost protection, 24ltr expansion vessel, neon diagnostic indicators and a factory fitted internal condensate trap (this can be sited externally if preferred), all designed to make installation and servicing easier. The Grant Vortex Pro Electronic Condensing Combi boilers are available in three sizes – 21kW, 26kW* and 36kW. 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.
