Solar water heater technologies have become increasingly popular in recent years due to their ability to provide a green solution for household heating needs. These systems harness the energy from the sun to heat water, reducing our reliance on finite energy resources and pollutants and lowering energy costs.
There are several types of solar water heater systems available, each with its unique features and advantages. The most common type is the direct circulation system, which involves the use of a heat exchanger. This system is relatively affordable and a great option for DIY solar installations.
Another type of solar water heater is the closed-system water heaters with additional heat transfer. This system is more sophisticated and with higher initial costs, but it offers greater performance and a longer lifespan.
