Direct SWH Systems: These systems are designed to heat the water directly, that is, utility water is heated directly in the collector panels.
Indirect SWH Systems: These systems should be used where water is corrosive or hard. They use a heat exchange method with glycol to heat water. Efficiencies are similar to a direct system. Indirect Solar water systems are especially applicable in alkaline areas such as the Rift Valley and Coastal regions or those areas that predominantly use borehole water.
- Domestic water heating.
- Industrial water heating, for example, in hotels, schools, hospitals, etc.
- Swimming pool water heating.
- Systems can be ground-mounted or roof-mounted (either coupled or split, depending on the customer’s requirements).
- A worthy investment compared to electricity heating with 3 to 4 years money-back on initial investment, depending on size of installation.
- Expected lifespan is up to 10 years plus.
- SWH systems are environmentally friendly.
- Very low maintenance; basically only flushing out sediments that may collect in the system every two years.
- System warranty is 5 years and workmanship warranty is 1 year.
