Solar geysers allow you to heat your water using the sun’s energy. There are two types of solar geyser systems that cater to diverse climates and water heating needs.
These two systems are direct (open-loop) and indirect (closed-loop) systems. It’s important to understand the distinctions between these systems so that you can decide which one suits you best.
DIRECT (OPEN-LOOP) SOLAR GEYSER SYSTEM
In this system, water circulates directly through the solar collectors, absorbing heat. Subsequently, a pump transfers the heated water into the storage tank for usage.
Direct systems are simpler and more cost-effective to install because they do not require heat exchangers or heat transfer fluid. They are ideal for regions with reliable access to safe drinking water and where freeze protection is not a concern.
INDIRECT (CLOSED-LOOP) SOLAR GEYSER SYSTEM
Indirect solar geyser systems use a heat transfer fluid (a glycol-water mixture) to absorb heat in the solar collectors. This heated fluid is then transferred through a heat exchanger, where it releases its heat to the water stored in the tank.
Indirect systems are best for areas with freezing temperatures as they provide freeze protection for the collectors and plumbing.
Let’s take a look now at the benefits of a solar geyser.
THE BENEFITS OF A SOLAR GEYSER
- You don’t need to rely on electricity
- The energy used is renewable, free, and unlimited
- Immense savings on your electricity bill
- A solar water geyser heats water very efficiently
- It’s environmentally friendly
- There is no use of fossil fuels
- Solar geysers have zero-emission
- It provides a lower carbon footprint
- A solar geyser is low-maintenance
We’re all feeling the financial pinch of living costs these days. In particular, the high cost of electricity is moving more people towards solar power. As a result, investing in a solar geyser is an effective way to reduce your electricity bill.
