      Additional cost relative to a standard electric water heater.

      Relies on a WiFi connection to the water heater. Without WiFi, you can't realise any benefits of the Smart technology.

    Always use a licensed plumber when installing a hot water system.

    The Thermann Smart Electric gives you more control over your hot water, energy use, and power bill with our new app-enhanced electric range.

    • View your energy use and power cost at a glance
    • Save money on your hot water bills by controlling when your hot water system heats water, reducing energy usage by not heating water unnecessarily.
    • Choose from four operating modes —
      • Manual Mode: Lower tank temperature to maximise savings, while keeping anti-legionella cycle.
      • Eco Mode: Machine learning can analyze usage patterns and adjust the heating cycle to reduce energy use by keeping heating to a minimum.
      • Holiday Mode: Remotely turn your hot water system on or off before holidays or when the house is vacant.
      • Schedule Mode: Adjust the hot water system to operate more efficiently around your home's unique schedule.
    Use our online optimiser tool to find out which mode is recommended for you.

    Important Note: The tank must be filled with water prior to connecting to a power source

      How it works

      1. A hot water tap is turned on

      2. Hot water is drawn from the top of the tank

      3. Cold water enters through the bottom of the tank

      4. When water temperature around the element drops, element activates

      5. Hot water rises to the top of the tank

      6. Control when the unit heats water to optimise functionality and save you money with the Thermann Control App

    Comparison disclaimer

    These are comparative figures that indicate the estimated savings that can be made by replacing a standard electric water heater with a smart electric water heater in the two following scenarios; (1) Household with a PV system fitted; (2) Household connected to a Time-of-Use (TOU) tariff. The amount of electricity used to operate the water heater for one year is calculated based on hot water usage and weather data conditions as specified in Australian/New Zealand Standard AS/NZS 4234 for a 4-person household based in Zone 3. Data displayed represents the savings achieved when comparing the Thermann Smart Electric 3.0kW, 315L model with the reference water heater. (1) Savings of up to $1000 for households with PV rely on at least 3kW of excess power being available between the hours of 10am and 3pm, using a single tariff rate of 35c per kWh, and a Feed in tariff (FiT) of 7c per kWh. (2) Savings of up to $650 for households with a TOU tariff, when the water heater is timed to heat during off-peak tariff periods versus peak tariff periods, assuming a controlled (off-peak) tariff rate of 20c per kWh, and a peak tariff rate of 35c per kWh.
