With eight models, available in internal and external variants, the Grant Vortex wall hung, oil condensing boiler offers high efficiency heating when space is at a premium.
All models have heating outputs ranging from 12-21kW, an ErP energy rating of A, and are endorsed by the Energy Saving Trust.
Grant supplies both sealed system and open-vented system variants. The boilers are pre-plumbed, and encompass Grant’s patented Vortex stainless steel heat exchanger and turbulator baffle system.
The sealed system versions include a factory fitted expansion vessel, filling loop, automatic air vent, pressure relief valve and high efficiency circulating pump. Consequently, these boilers can be installed without the need for a feed and expansion tank in the loft.
Vortex internal wall hung boilers require a separate flue kit and are compatible with all Grant EZ-Fit low level, high level and vertical flue systems. Meanwhile, the external models come complete with a factory fitted flue, external powder coated finish, built-in boiler frost protection, mains isolating switch, and a test switch.
Furthermore, being a condensing boiler, the Vortex captures and reuses heat normally lost through the flue system, resulting in higher efficiency levels and lower heating and hot water running costs.
If floor space within a property is limited, installing a wall hung boiler either within or outside the building is sometimes the only option and Grant’s Vortex wall hung range caters for these situations.
