Abstract
The control device for conserving energy for heating water contained in a water heater (30) comprises an electronic detection device (21) for measuring the quantity of hot water remaining in the tank (2), the electronic detection device (21) consisting of a capillary tube (10) containing a heat transfer fluid and an amplification device (15) placed outside the tank (2) of the water heater (30) and connected to an electronic control card (26), the amplification device (15) being suitable for transmitting a variation in resistance to the electronic control card (26) under the effect of the expansion of the fluid contained in the capillary tube (10) and control means (50) connected to the electronic control card (26) for determining the hot water consumption profile of the users in order to control the period or periods of resumption of the heating of the water in the tank (2).
