The latest Grant Vortex External condensing 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.
They 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 boilers come in three sizes – 21kW, 26kW and 36kW.
With larger than normal heat exchangers, the hot water performance on a Grant Vortex external combi is vastly increased. Featuring two very accurate electronic temperature controls, which allow the boiler to operate in condensing mode on central heating, instant hot water production can be maintained.
