The Robinsun Solar Boiler makes heating water with solar energy easy, allowing you to save money in a smart and sustainable way.

- Set up your boiler and connect it to your water supply.
- Screw the heating rods from the controller into your boiler.
- Plug the controller into a power socket for backup energy.
And that’s it! Your boiler starts heating water using solar energy. And if there’s not enough sun, it automatically switches to grid power, so you never run out of hot water.
No need for complex installations. Our system is self-installable, and with its smart controller, you stay in charge of your temperature and reheating times.
Clean, reliably energy – powered by Robinsun.
