How does a SunGeyza work?

A heavy duty black solar water heater facing the sun at an angle, is manually filled up with water. The black front panel is heated up by the sun, which transfers the heat to the water inside the geyser. An insulated panel on the side not facing the sun prevents the heated water from cooling down again.

When the sun sets, the front black panel is covered with the green insulation panel, which secures an all round insulation to the geyser.

Sustainable solution

Unlike clean cook stoves and solar ovens, the SunGeyza solar water
heater is widely accepted. It eliminates the possibility of the household
ever turning back to old ways. When the sun is shining, it heats up

“Just fill it” and the sun will do the rest

At the end of the SunGeyza life cycle, the household will have become
so used to free solar heated hot water every day, that they will not
hesitate one moment to replace the heater immediately at own cost.

Advertising Opportunity

The green (or any colour of choice) front insulation panel is available as advertising space. By selling this advertising space in exchange for a free solar hot water heater, a win, win situation is created. Please get in contact.

How much water does the SunGeyza heats up?

The SunGeyza heats up 25 liters of water, which should normally be cooled down with cold water to the required temperature. According to research in our target market the average household in our target market heats up less than 25 liters of water per day for household purposes. If more hot water is required a second, third or fourth heater can easily be applied.


The possibility of theft is minimal as the heater has no recycling value. To link a SunGeyza to a household and to further prevent any possible illegal removal, a permanent phone number or address can be put on the green area.
