Overview
The Vaillant Unistor unvented hot water storage cylinder can be used when converting from an open-vented system with a cold water tank in the loft to a sealed boiler and cylinder system, thus saving space and enhancing water pressure. Upgrading an old copper cylinder to a new Unistor unvented cylinder as part of a heating system improvement will reduce cylinder heat losses, which results in increasing the efficiency of the heating system as well as saving money on your fuel bills.
- Can be retrofitted onto older systems meaning you can upgrade your cylinder without the hassle of the entire system
- 2 years guarantee on parts and labour plus 25 years guarantee for the cylinder shell which gives you total peace of mind
- Thermodynamically positioned sensor pocket optimises system performance.
- Global Warming Potential less than five and ozone depletion of zero Designed to have minimal environmental impact.
- Factory fitted immersion heater boost, and emergency backup in case of main heat source failure.
