The Grant Vortex Eco Utility range was launched as a direct response to customer demand for a competitively priced condensing boiler.

The Vortex Eco Utility boilers have a simplified casing, control panel and pipework arrangement. Each model incorporates the latest Riello RDB burner as well as Grant’s patented stainless steel heat exchanger. The range is simple to service with the burner and combustion chambers positions towards the front of each boiler.
