Hot water tank control

When the water tank is at temperature should the standard thermostat on the side of my tank tell the tado to click the hotwater to off and turn off the relay as when my hot water is on for 5 hours it runs the boiler that long!


  • The tank thermostat should turn off the pump and boiler when the tank reaches temperature. Tado had no way to know this has happened so will still show the HW as being on in the schedule. This would be no different with a traditional heating controller

    You should check that the pump and boiler do shutdown when the tank reaches temperature as there may be a fault that is keeping everything running
