Thermino thermal storage for domestic hot water

Sunamp's Thermino thermal batteries make homes more energy efficient and sustainable by efficiently storing heat to deliver instant, high flow-rate hot water when needed while reducing carbon emissions.

The Thermino battery range maximises the use of renewable energy by catering for a wide range of energy sources. They can be charged by air source heat pumps, ground source heat pumps, photovoltaics (PV), grid electricity and boilers.

Save space

Easy to install, up to four times smaller than the equivalent hot water cylinder and requiring no mandatory annual maintenance, their sleek, super-compact design means they look good in any home and free up valuable storage space.

Retrofit or specify for new builds

Thermino is designed to be retrofitted to existing hot water systems or specified for use in new build projects. Modular and scalable, the batteries can be connected in series or in parallel to increase heat storage capacity. 

Sustained by Plentigrade

Thermino is the fourth-generation battery range to contain our high-performance phase change material, Plentigrade.

For Thermino, we improved the flagship Plentigrade P58 formulation to deliver greater storage capacity resulting in more hot water from the same compact thermal battery size as the third-generation product range, UniQ.

Being our next generation of heat batteries, Thermino is also optimised for heat pumps as the heat exchanger has a new design to greatly reduce pressure losses on the primary circuit.

Thermino range overview

Thermino hp 

Enables heat pumps to be installed for homes with no space for an indirect hot water cylinder. Specific Thermino hp models are available for selected heat pumps from leading manufacturers such as Vaillant, Daikin, Kensa and Samsung.

  • Heat source: heat pump, boosted electrically if required

Thermino epv

Replaces a direct cylinder to deliver hot water efficiently from solar PV, with off-peak grid electricity for greater flexibility when needed. 

  • Heat source: solar PV, boosted electrically if required

Thermino ipv

Delivers hot water efficiently from solar PV as an indirect cylinder replacement, with off-peak grid electricity for greater flexibility when needed. 

  • Heat source: solar PV, boosted electrically if required

Thermino e 

Charges using grid electricity, Thermino e is a sleek alternative to direct hot water cylinders with an optional programmable timer to maximise off peak/variable tariffs. 

  • Heat source: grid electricity

Thermino 

Works with boilers to store heat, Themino is a space-saving alternative to indirectly heated vented and unvented hot water cylinders. 

  • Heat source: boilers

Thermino i

Like the Thermino, the Thermino i model also works with boilers as an alternative to indirectly heated vented and unvented hot water cylinders but comes with a standby internal electric heating element.

  • Heat source: boilers, with grid electricity as a secondary charge source
Sunamp Thermino heat battery product

Thermino heat batteries are available in 70, 150, 210 and 300 sizes, which are industry-friendly litres equivalent measurements to allow for direct comparison with traditional hot water cylinders.

Additional sizes (180 and 250) will be introduced in the second quarter of 2022.
