Telford Tempest Heatpump Unvented Cylinder

Product Code: TSMIHP

With developers using more renewable energy sources than ever before, the Tempest Heat Pump is now available to be used with Air/Ground source heat pumps. This version is available in single coil where Heat Pump is the only heat source and Twin Coil where solar or a boiler is also available.

As with all ranges of our Tempest we are so confident in the construction that we have given the Tempest Heat Pump a lifetime warranty.

Our standard Heat Pump coil has a surface area of 3.3m2, as a result, the smallest tank we can offer is a 200litre. Smaller capacity cylinders are available where a lower surface area coil can be used.

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