Telford Tempest 250Ltr Indirec Unvented Horizontal Cylinder

Telford Tempest 250Ltr Indirec Unvented Horizontal Cylinder

The Telford Tempest 250Ltr Indirect Unvented Horizontal Cylinder is a high-performance hot water storage solution designed for properties where vertical space is at a premium. By utilizing a horizontal orientation, this 250-litre unvented cylinder can be easily installed in restricted areas such as lofts, roof voids, or basement crawl spaces, while still delivering the powerful mains pressure performance expected from a premium system.

Optimized for Restricted Spaces

Standard vertical cylinders often require significant headroom that modern loft conversions or compact utility areas cannot provide. The Tempest Horizontal range solves this by using specialized internal baffling to ensure efficient heat stratification. This ensures that you receive a consistent flow of hot water even in a horizontal configuration, making it ideal for 3–4 bedroom homes with multiple bathrooms.

High-Grade Duplex Stainless Steel Construction

Manufactured in the UK, the Telford Tempest is built from Duplex 2304 stainless steel. This material is renowned for its exceptional strength and superior resistance to corrosion compared to lower-grade stainless steel alternatives. Because of the high-integrity build, the cylinder does not require a sacrificial anode, reducing long-term maintenance requirements and providing a "fit and forget" solution for installers and homeowners alike.
