The full Thermino Plus range 70 to 300.

Sunamp hot water batteries maximise the use of renewable energy and can be charged by air-source heat pumps, ground-source heat pumps, grid electricity, boilers, and are also future-proofed for solar PV.


Ideal for retrofitting to existing hot water systems as well as specifying for use in new build projects. Their sleek, super-compact design means they look good in any home and free-up valuable storage space.


Up to four times smaller than the average family’s hot water cylinder and can be a complete replacement.


Thermino batteries come with a market-leading 10-year warranty. What’s more, their batteries are easy to install and require no routine maintenance.
