Telford Tempest 250Ltr Indirect Unvented Cyclinder

Telford Tempest 250Ltr Indirect Unvented Cyclinder

The Telford Tempest 250Ltr Indirect Unvented Cylinder is a high-performance hot water storage solution engineered for larger family homes with high hot water demands. Designed to provide powerful mains pressure water to multiple outlets simultaneously, this 250-litre unvented cylinder is the ideal upgrade for households with 2 to 3 bathrooms, ensuring consistent flow rates for showers and rapid filling for large baths.

Premium British Engineering: Duplex Stainless Steel

Durability and reliability are the foundations of the Telford Tempest range. This cylinder is manufactured in the UK from high-grade Duplex 2304 stainless steel, which offers superior strength and exceptional resistance to corrosion compared to standard stainless steel or copper units. Because of its robust material properties, it does not require a sacrificial anode, significantly reducing long-term maintenance costs and extending the lifespan of the system.

High-Efficiency Indirect Heating

As an indirect unvented cylinder, this model is designed to be heated by your central heating boiler (gas, oil, or electric) via a high-performance internal corrugated coil. The coil’s design maximizes the surface area for heat exchange, leading to rapid reheat times. This ensures that even after heavy morning usage, your hot water supply is replenished quickly and efficiently.
