Thermino e heat batteries are the smart way to heat water and save space and money too, especially when combined with an off-peak tariff. They are the ideal replacement for direct hot water cylinders. Heated by an internal element, which is covered by Sunamp's market-leading 10-year warranty, they guarantee powerful showers at a perfect temperature.

A sleek new design and advanced storage technology make them up to four times smaller than equivalent direct cylinders, freeing up valuable storage space in the home.
