Grant UK upgrades oil-fired combi

Grant UK’s Vortex Pro oil-fired combi now includes a 24 litre expansion vessel as standard, a safeguard designed to provide expansion capacity for both the boiler and the heating system.

The company says it regularly consults installers regarding improvements that they would like to see made to products, and a larger factory fitted expansion vessel for the combi was high on the list.

Grant Vortex Pro Combi Internal  (3)“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 company explained.

The Vortex Combi range includes internal and external models available in output of 21 kW, 26 kW and 36 kW. The latest Combi XS 26kW boiler is 515 mm wide and claimed to be 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.
