The Grant Vortex Pro Combi XS has almost identical characteristics on both combustion efficiency and domestic hot water performance as its larger version and utilises all of the existing components so will be immediately familiar to installers of Grant products. To save on space however, the 24 litre expansion vessel, normally located behind the front door of the boiler, is supplied as an ‘externally fitted vessel kit’.
“As a result of feedback from our G-One approved installer network, we developed this more compact Pro Combi XS to ensure our combi boilers can directly replace older inefficient models,” explains Anna Wakefield, marketing manager for Grant UK. “Grant have been manufacturing combi boilers for around 17 years and today 1 in every 3 oil boilers we sell is a combi version. The Vortex Pro Combi XS completes our range and meets the requirements of our installer network.”
The Vortex range features 46 different model variations, with outputs from 12 to 70kW and around 1 in every 2 boilers installed in the UK is now a Grant Vortex (Source: SBGI).
