HWQ concept


*The vision: According to the renowned Enertech design office, which specializes in the energy performance of buildings: "Between 35% (in the best case) and 60% of the heat from a Domestic Hot Water (DHW) production installation is lost in distribution, between the storage tank and the taps"... According to ADEME, these distribution losses represent up to 30% of the price of hot water in collective buildings. Born from this observation, HWQ, the new instant hot water transfer technology was born to improve our daily lives. *The solution : The HotWaterQuickly device is not a means of hot water production. The process is simple to understand! Each time it is used, a powerful motorized pump channels the hot water from the reserve, to inject it under a 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) to the tap(s). These can be located more than 60 meters from the hot water source. *Activity and impact The interest of such a device remains certain in the individual home! However, the market study carried out when the "French Tech Emergence" grant was awarded in 2018 showed that it is even more so in collective buildings. Therefore, the company is initially concentrating on the research, development, and marketing of the HWQ device, intended for residential buildings, hotels, hospitals and medical complexes, both new and pre-existing. The device considerably reduces our risk of exposure to dangerous bacteria such as Legionella. Indeed, the small quantity of water, the high pressure, and the absence of biofilm in the pipes are all factors that prevent the proliferation of bacteria in the network. The hospital environment is particularly affected by this problem! The device is a connected object that makes it possible to know in real time, via a digital application, the volume of hot water consumed at each tapping point. It is a high-performance tool that allows you to efficiently manage your hot and cold water consumption (if your teenager has taken a shower that is a little too long, you will be able to know the exact price, which may be passed on to him or her in their pocket money :)). A sub-program makes it possible to detect abnormal consumption (e.g. a leak or a tap left open accidentally...), and to warn those concerned by SMS or e-mail.
