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. Read our full review to find out whether the Vortex Pro External 46-58 is the best boiler for your home.
