Boilers: Compare features & prices Grant Vortex Pro External 15-26 review Back to Results

At first glance, Grant's Vortex Pro External condensing oil-fired boilers appear very similar to the Vortex Eco External range, but the Pro models benefit from higher efficiencies and are factory-wired to receive an optional RF wireless programmer. This enables the boiler to be controlled remotely from any room inside the house without the need for hard wiring. As with the Eco range, you can also purchase an optional conversion kit to convert these open-vent boilers into sealed-system boilers.
