Solar heater manufacture. Technician welding part of a solar water heater. This is the flat plate collector, which absorbs sunlight and warms water passing through the pipes. The heated water rises to a storage tank (not seen) by convection, and cooler water sinks down into the collector. This system is known as a thermosiphon solar water heater. It harnesses the renewable energy of the sun, is relatively cheap to install and maintain, and produces no waste products. These heaters are manufactured in Bangalore, India.
