The special Doro-Cup cover protects your solar water heater from the sun in your absence and significantly reduces the internal temperature, thereby extending the lifespan of your solar heater.

It protects solar water heaters from the sun's rays when you are away for long periods from home, the cottage, etc. The water accumulated inside the boiler can reach temperatures up to 80°C and, as it is not used, it literally boils, resulting in the wear and tear of your solar heater and the water supply network of your residence.

The cover is made of aluminum and PEX foam class E insulation
