Tap into the future of hot water: thermal storage

Boost your business and get ahead of the competition

Thermino heat batteries are the ideal hot water system for you and your customers


Space-saving

Optimises renewables

Easy to fit

No mandatory maintenance

Thermino batteries work with a range of energy sources, including heat pumps and solar, to provide high flow rate hot water for your customers. With 25,000 installed worldwide, make the most of the move to low-carbon heat by becoming a Sunamp certified installer.

The systems take up a quarter of the space of an equivalent hot water cylinder, freeing up valuable storage space and making it possible to switch to a heat pump, even if there isn’t room for a cylinder. They’re easy to install and quicker to fit than a cylinder, with no need for ongoing maintenance or Legionella checks.

Flexible, future-proof and easy to fit: A thermal battery is the ideal hot water cylinder replacement

Thermino batteries are up to 4x smaller than the equivalent hot water cylinder, allowing customers to switch to a heat pump even if they’re short on space.

How thermal storage can maximise the benefits of heat pump and solar installs

A heat battery can store the energy captured by a heat pump or generated by solar panels, and use this to provide high flow rate hot water on demand.

Help your customers improve their EPC rating with thermal storage

With customers increasingly prioritising sustainability and energy performance, efficient and sustainable thermal storage can help your customers improve their energy performance ratings.
