Grant Vortex Condensing Outdoor Combi Boiler 21



For almost two years Grant has been working behind the scenes on brand new electronic versions of the successful Grant Vortex Combi Range with the aim of incorporating as many of the additional features and benefits customers have requested, whilst bringing the technology installed in these appliances up to the minute. The new models now include internal frost protection, neon diagnostic indicators and a factory fitted internal condensate trap (this can be sited externally if preferred), which are designed to make installation and servicing easier. Grant Vortex Pro Combi’s feature much larger plate heat exchangers which due to their low water content and larger surface area, vastly increase the hot water performance available. Mixing valves are pre-set at 50°C, controlling accurately the hot water draw off temperature from the boiler. They also feature a low system pressure cut off switch, enabling the combi to protect 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.
