Faucets that have access to hot water in less than 3 seconds without using a hot water loop

Every morning, to access the hot water, we have only two choices:

- Either we have a simple circuit and we must first wait during the evacuation of cold water that is present in the pipes of hot water, water that is most often wasted in the sewer. Hot water often has to wait for more than a minute when water saving devices have been installed that reduce the flow to the faucets. An average of 20 to 40 L of water is wasted per day, per house.

- Either we have a hot water recirculation loop that reduces the waiting time to a few seconds but in this case, we waste 10 to 20 KWh / day only to keep hot water at the temperature in the pipes. In summer, the recirculation loop heats the walls while using air conditioning to lower the room temperature, a double waste since there is usually no separate switch to control the circulation pump. Hot water. At the plant, it takes at least 4 liters of water to produce 1 kWh, on average 8 L and more to take into account the evaporation in the cooling towers. The hot water recirculation loop wastes a lot more than 40 L of water a day, but the waste is taking place at the plant and the user is not aware of it.

In addition to accelerating the delivery of hot water, ecological faucets have the same appearance, functions, and handling as conventional faucets. The range includes simple hot water faucets, mixer faucets, thermostatic faucets and thermostatic shower enclosures with downstream looping through the shower head, which allow entry into the shower before opening the faucet without fear of the slightest drop. of cold water.

Technology that accelerates hot water supply to the faucet to make it available in less than 3 seconds when the water heater is 10 m is currently only disclosed as part of a confidentiality agreement.
