The Vortex Pro is a range of condensing oil fired combi boiler from Grant a leading manufacturer of high efficiency oil boilers. The Vortex Pro is an electronic version of Grants successful Vortex Combi boiler range that was developed over 2 years incorporating the latest technology and additional features requested by customers and installers. New features include internal frost protection, a neon diagnostic indicators and factory fitted internal condensate trap (can also be fitted externally if required) making installation and servicing quicker and easier. The Vortex Pro is available in a range of outputs including 21kW, 26kW and 36kW in either an internal or external model providing flexibility when siting the boiler.

The Grant Vortex Pro range is fitted with large heat exchangers which hold a small volume of water, this low water volume combined with a large surface area vastly increases the boilers performance and energy efficiency. Also with mixing valves, pre-set to 50°C, the hot water draw off from the boiler can be accurately controlled and with a low system pressure switch the boiler can protect itself against system water loss. The Vortex Pro also features highly accurate electronic temperature controls allowing the boiler to operate in condensing mode for the central heating whilst maintaining its instant domestic hot water production.
