Telford Tempest 300Ltr Slim Indirect Unvented Cyclinder

Telford Tempest 300Ltr Slim Indirect Unvented Cyclinder

The Telford Tempest Unvented Cylinder High Gain 300Ltr is a premium, high-performance hot water solution specifically engineered for use with modern renewable energy sources like air source heat pumps and ground source heat pumps. As a market leader in water heating efficiency, this 300-litre model provides ample hot water storage for larger family homes with multiple bathrooms, ensuring high flow rates and consistent water pressure throughout the property.

Exceptional Heat Transfer & Efficiency

Unlike standard cylinders, the Tempest High Gain range features an enhanced, high-surface-area heat exchanger coil. This "high gain" design allows for maximum heat transfer even at the lower flow temperatures typically produced by heat pumps. This ensures your system operates at peak COP (Coefficient of Performance), reducing energy bills and your carbon footprint.

Built to Last: Duplex Stainless Steel

Durability is at the core of the Telford Tempest. Manufactured from high-grade Duplex 2304 stainless steel, this cylinder offers superior resistance to corrosion compared to standard grades. It is designed to withstand the rigors of a high-pressure unvented system without the need for a sacrificial anode, significantly reducing long-term maintenance requirements.
