Why Choose an Unvented Cylinder?

Unvented cylinders deliver hot water at mains pressure, meaning stronger showers and better water flow from taps compared to traditional vented systems.

Modern unvented cylinders like the Vaillant uniSTOR are also highly insulated, helping to reduce heat loss and improve energy efficiency.
