Submitted by Baerbel Epp on May 3, 2011

 Orkli stand-alone solar water heater” The first time Spanish company Orkli, S. Coop presented its stand-alone solar water heater with an integrated storage tank was at the international heating fair ISH in Frankfurt, Germany, in March. The 80 kg element includes all the components of a standard solar water heater, such as a metal absorber coated with black chrome, an expansion vessel, a recirculation pump, safety valves, a heat exchanger, and a storage tank. The small PV panel in the left-hand corner of the collector which supplies the pump renders the system completely autonomous.
