Looking for an all-electric hot water system?

A Sunamp thermal battery is up to 4 times smaller than the hot water cylinder it replaces whilst still giving instant hot water – with no water storage.

A Sunamp thermal battery gives up to 4 times higher energy efficiency than alternative systems leading to lower energy use to heat your water.

You get instant hot water (with no water storage) for hygiene and freshness. Our batteries are all non-toxic, with no risk of legionella.

Sunamp heat batteries can be charged with large amounts of energy from renewable and other sources, and released to deliver hot water on demand in your home so you can use & store more of your solar electricity generation.

Sunamp’s heat storage cells come with a market-leading 10-year warranty, and you can rely on them to keep working without degradation for decades after that.

Delivered with high-quality brass push-fit connectors in the box to allow for easy installation and no annual maintenance is required.

Sunamp water heaters are very heavy, with the smallest version weighing 70kg and the largest coming in at 220kg. The unit cannot be tilted by more than 45º during the transportation and installation process and so special care must be taken during this time.
