Grant - Wall Hung

The launch of Grant’s first wall hung oil-fired boiler range comprising two indoor and two outdoor SEDBUK ‘A’ rated models, is an exciting addition to the Vortex family. Available in outputs ranging from 40,000 – 70,000 Btu/hr in open vented system versions, the new appliances encompass Grant’s patented Vortex stainless steel heat exchanger and turbulator baffle system.

All Indoor wall hung models require a separate flue kit (not supplied with the boiler) and are compatible with all Grant EZ-Fit low level, high level and vertical flue systems, so now almost any installation situation can be catered for.

All Outdoor wall hung modules come complete with a factory fitted flue, high quality external powder coated paint finish, built-in boiler frost protection, mains isolating switch and a test switch.
