Grant Vortex Pro Internal models are designed to suit kitchens and utility rooms, delivering both choice and performance across the range.
The Vortex Pro Internal range is incredibly efficient, combining the latest Riello burner technology with Grant’s trusted, patented technologies. The models available within range are ideal for direct boiler replacements of older oil-fired models.
a HeatingUnlike traditional oil-fired boilers, the Vortex and VortexBlue condensing boiler has a built-in stainless-steel heat exchanger incorporating Grant’s unique turbulator baffle system which cools the gases to a point where the latent heat, normally lost to the atmosphere through the flue, can be usefully extracted. The additional energy recovered enables the boiler to operate continuously at much higher efficiency levels, resulting in lower heating and hot water running costs.
