Grant Vortex Pro External Regular review
Brand score %
- Heat-only or regular
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. Read our full review to find out whether the Vortex Pro External is the best boiler for your home and how reliable Grant boilers are compared to the rest of the market.
