A device using motorized pumps to deliver hot water in 2 seconds to the taps, avoiding energy and water waste

The distribution of Domestic Hot Water (DHW) have many drawbacks. They are a source of discomfort, waste of water and energy, and a bacteriological risk. According to Enertech specialized in the energy performance of the building: “Between 35% and 60% heat of a domestic hot water production facility (DHW) is lost in the distribution, between the storage tank and the taps. Continuous operation loop distribution and widespread in apartment buildings are the main causes of these losses“. To tackle this challenge, the HotWaterQuickly delivers hot water instantly in less than 2 seconds to all taps. Indeed, in each building, a powerful motorized pump channels the hot water from the reserve, to inject it at high pressure (250 bars) into a very small section pipe (3.5mm diameter), which conducts the hot water at high speed (at nearly 100Km/h). This way, the water is provided very quickly into the customer taps.
