The Grant Vortex Eco range was launched as a direct response to customer demand for a competitively priced condensing boiler. The Eco models incorporate the latest version of the Grant Vortex stainless steel heat exchanger and are exceptionally quiet in operation featuring the latest Riello burner technology. The models incorporate the same unique features as the Pro range, offering a factory fitted multi-directional flue, high quality external powder coated casing, built in frost protection, mains isolating switch and a test switch.
