Black Coral – A Mini Solar Water Heater.

‘Black Coral’, a mini solar water heater attachable to the outer wall of a building is devised to supply 50 liters of hot water which is an average amount of water consumed by an adult per day.
‘Black Coral’ absorbs solar heat through 40 exchangeable vacuum tubes. The absorbed heat warms up the water which is then sent to a hot water tank.
‘Black Coral’ is an appropriate model for apartment houses because its design allows it to minimize the space in which it can be installed.
