Telford Tempest Unvented Indirect Horizontal Cylinder

Product Code: TSMIH

The Telford Tempest Unvented Indirect Horizontal Cylinder is the perfect choice for those who want a high-quality, durable, and long-lasting hot water cylinder. Made from premium-grade Duplex stainless steel, the Tempest is resistant to corrosion and will provide years of reliable service.

Here are some of the things that make the Telford Tempest Unvented Indirect Horizontal Cylinder stand out from the competition:

  • Premium grade Duplex stainless steel: The Tempest is made from premium grade Duplex stainless steel, which is up to 40% thicker than some of the lower grade stainless steel used by other manufacturers. This makes the Tempest more resistant to corrosion and ensures that it will last for many years.
  • Lifetime warranty: Telford is so confident in the quality of their products that they offer a lifetime warranty on the Tempest. This means that you can be sure that your investment is protected.
  • Indirect design: The Tempest has an indirect design that allows it to be heated by a boiler or heat pump. This means that you can use the Tempest to provide hot water for your home even if there is a power outage.
  • Horizontal design: The Tempest has a horizontal design that takes up less space in your loft than traditional vertical cylinders. This makes it ideal for homes with limited loft space.
  • High-density insulation: The Tempest is insulated with high-density insulation that keeps your hot water hot for longer. This means that you’ll use less energy and save money on your heating bills.
  • Full unvented kit supplied: The Tempest comes with a full unvented kit supplied, including a remote expansion vessel. This means that you can install the Tempest quickly and easily without having to purchase any additional parts.
  • WRAS-approved: The Tempest is WRAS approved, which means that it meets the highest standards of safety and quality.
  • Treated to protect against corrosion: The Tempest is treated to protect against corrosion, which further extends its lifespan.

If you’re looking for a top-quality, unvented hot water cylinder, the Telford Tempest is a perfect choice. Order yours today and enjoy peace of mind for years to come.
