Solar Water Heating or Solar Geyser Systems

The functionality of a solar water heating system or solar geyser - The geyser unit, also known as a water storage vessel or water heating storage compartment, is commonly installed above or at a higher point than the solar collector tube unit. The sun's radiation enables the water in these tubes to warm up. Cooler water descent to the lowest point in the system while the warmest water is highest, causing continuous water circulations and effectively heating the water for usage. The solar collector tubes are frost resistant and provide good efficiency as the collector is not influenced by ambient temperature but mostly rely on the sun's radiation. These heat water directly as there is no risk of freezing even in temperatures below freezing point.

Like solar tube collector units, flat plate collector units do not consist of outer tubes. Unlike a visible tube collector unit, a flat plate solar collector unit consists of tubing and copper sheets covered with a dark absorbency efficient material. This material prevents heat from escaping and ensure that the collector is well insulated. The cold water inside the tubes will start to heat up when the sun's radiation transforms to thermal energy, which will cause the hot water to rise to the top of the solar tube and will the outlet lead the hot water to the water heating storage compartment or geyser.

Flat plate collectors are a newer form of technology and, therefore, more prevalent in heating water.

Why are flat plate collectors so popular with new installations, you may ask?

• Cheaper.
• Durability, which lasts longer since the solid plate is used as a cover.
• Available in different designs ready to be installed
• Reduces energy consumption to approximately 50%
• Depending on the weather, it can collect and heat between 200 and 400 liters of water per day.
• Very little to almost no maintenance
