Uniq


Sunamp’s Uniq heat battery range is widely installed in homes across the UK. It was succeeded by Thermino, our fourth-generation products for domestic hot water, in December 2021. 

Our Thermino thermal batteries build on the success of Uniq and, like their predecessor, replace traditional hot water cylinders – direct (for grid electricity and solar PV) or indirect (for boilers and heat pumps). 

Below you’ll find instruction manuals for each Uniq battery model.


There are four different models: the Thermino 70 e, 150 e, 210 e and 300 e. They are in litre-equivalent sizes for easy comparison with traditional hot water cylinders. 

Modular and scalable, our thermal batteries can be connected in series or in parallel to increase heat storage capacity.

  • Flexible orientation with plumbing exits on three sides 
  • Market-leading 10-year warranty on the heating element
  • No mandatory annual maintenance
