Vaillant’s uniSTOR range of unvented stainless-steel cylinders offers capacities from 120 to 800 l, making them suitable for large residential and commercial projects — particularly the cylinders with capacities of 500 and 800 l. These larger cylinders come with the option of a 7.5 kW immersion heater.

The new range complies with all ErP requirements, with some cylinders achieving an ErP A-rated classification and ‘best-in-class’ heat-loss performance.

Upgrading an old copper cylinder to a uniSTOR unvented cylinder as part of a heating system upgrade will help achieve a more efficient system.

All cylinders come with a 25-year guarantee for the outer shell and are supplied with fittings to ensure compliance with section G3 of current Building Regulations.
