It’s all in the size of the vessel
One of the latest developments on the Grant Vortex Pro oil-fired combi is that it has a 24 litre expansion vessel as standard – a safeguard that provides excellent expansion capacity for both the boiler and the heating system.
By upgrading to a 24 litre expansion vessel, the boilers will ultimately save on installation time and costs because, in most cases, no additional external vessel will be required. For the majority of installations, 24 litres will provide more than sufficient room for the expansion from both the boiler and heating system.
The Vortex Combi range includes internal and external models available in output of 21kW, 26kW and 36kW. What’s more the latest Combi XS 26kW boiler is only 515mm wide and the slimmest model of its kind on the market. The 24 litre expansion vessel is normally fitted behind the front door on indoor and outdoor Vortex Pro combi boilers, but with the XS, it is supplied as an externally fitted kit.
Designed to make installation and servicing easier, and providing excellent combustion efficiency and hot water performance, Grant Vortex Pro Combis are a favoured choice for installers and homeowners alike.
