Vaillant Cylinders

The uniSTOR heat pump cylinder range has been designed to work in harmony with Vaillant heat pumps, to provide highly efficient heating and hot water systems.

A uniSTOR’s large surface area and smooth coil design maximises heat transfer, to ensure connected Vailllant heat pumps run at their optimum efficiency. This reduces running costs and increases hot water performance.

Ranging from 150 up to 800 litres, our uniSTOR heat pump cylinders are available in both pre-plumbed (150-300 litres only) and standard options, giving you even more flexibility. In addition to this, the 250 and 300 litre cylinders have an increased coil size making them compatible with a wider range of ground source heat pump systems.
