20130205493 | Ecoshower - Device for recirculating shower water: a mixing device is connected directly to the hot and cold water inlets, the cold water inlet is connected to a recirculation system; a pump is actuated while the cold water inlet is cut off. In such a device, the hot water flow rate is kept by the mixing device just high enough to compensate for the thermal losses of the water circulating through the system. Water losses are thus minimized to the strict requirement. Advantage: partial continual renewal of the shower water, unlike systems involving full recirculation. | 08-15-2013 |
