Telford Tempest Unvented  Twin Coil Cylinder (PLUS)

Product Code: TSMIS/Plus

The Telford Tempest Twin Coil has been a member of our product range for many years now. As renewable heat sources continue to get more funding and more efficient there is no better time to invest in a solar product, whether it’s for future proofing or a ready to go installation.

Our Solar range is manufactured to the same high standards as any other version of the Tempest, carrying the same lifetime guarantee.

We have also partnered with Mint Renewables to offer industry-leading solar panels at a great price. Visit our Solar section on the homepage to learn more about the panels.

At Installers Hub we sell a wide range of Telford Cylinders.
