An unvented cylinder is used to store domestic water that is heated by a system / regular boiler or by a renewable heat source such as solar thermal.
Compact and flexible unvented cylinder
- High performance mains pressure to all hot water outlets
- Inner tank is guaranteed for 25 years (2 years on ancillary components)
Vokèra unvented cylinders maintain mains water pressure no matter where the unvented cylinder is located throughout the property. Unvented cylinders generally offer high performance hot water flow rates and are particularly suited to properties that have multiple bathrooms.
There are two types of Vokèra unvented cylinder: single coil unvented cylinders and twin coil unvented cylinders. In most properties with an unvented cylinder it is likely to be a single coil unvented cylinder. The benefit of a twin coil cylinder is that it allows the heating system to also be connected to a solar panel. So if you are considering having a solar thermal installation at some point and you require a new unvented cylinder, it may make economical sense to invest in a twin coil unvented cylinder. With heat pumps, an unvented cylinder with a larger coil is required to work with the lower temperatures at which heat pumps operate.
