UniQ thermal battery range for domestic hot water


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.
