Product details

The Telford Tempest is a flagship stainless steel unvented cylinder. Over the years there have been changes in the hot water industry that have caused manufacturers to offer lower grade stainless steel to remain competitive.

All Telford stainless products have remained the same high grade of stainless steel, up to 40% thicker than some products on the market today.

Each Tempest cylinder is protected in a 30mm thick high density polyurethane foam for maximum protection against heat loss, backed up by a Lifetime Warranty*

  • Re-heat from Cold : 36 Minutes
  • Re-heat from 75% Draw off with Boiler : 25 Minutes
