Vaillant uniSTOR Standard Indirect Unvented Hot Water Cylinders
The Vaillant uniSTOR unvented hot water storage cylinders 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 saving space and improving water pressure. Upgrading an old copper cylinder to a new uniSTOR unvented cylinder as part of a heating system upgrade will reduce cylinder heat losses, making your heating system more efficient and saving money on your fuel bills.
