What is a Solar Water Heater?
Solar water heaters use solar energy from the sun to generate heat which is used to heat water for domestic, commercial or industrial uses like showering, space heating, industrial processes or even solar cooling.
Installing a Solar Water Heater is a substantial investment
CoolKenya will conduct a site survey to determine the best suitable & most economical solar water heating equipment that fits your needs & let us advice you accordingly.
Circulation Systems |
---|
Direct systems circulate water through solar collectors where it is heated by the sun. The heated water is then stored in a tank, sent to a tankless water heater, or used directly. These systems are preferable in climates where it rarely freezes. Freeze protection is necessary in cold climates. |
Closed-loop, or indirect, systems use a non-freezing liquid to transfer heat from the sun to water in a storage tank. The sun's thermal energy heats the fluid in the solar collectors. Then, this fluid passes through a heat exchanger in the storage tank, transferring the heat to the water. The non-freezing fluid then cycles back to the collectors. These systems make sense in freezing climates. |
Active, or forced-circulation, systems use electric pumps, valves and controllers to move water from the collectors to the storage tank. These are common in the U.S. |
Passive systems require no pumps. Natural convection moves water from the collectors to the storage tank as it heats up |
Using sunshine to heat or preheat your water with CoolKenya's ENERGY STAR certified solar water heating system can cut your annual hotwater electricity BILLS in HALF!
