Pros and cons

According to our thermostat expert
  • Control and read the temperature via an app on your smartphone and on the radiator knob itself.
  • Set time schedules for each day of the week and save energy.
  • The radiator thermostat runs on 2 AA batteries that must be replaced every now and then.
  • To use the expansion, you need at least a Tado bridge.
  • You can only install this smart radiator thermostat on your heater if you already have a thermostatic radiator knob. You can recognize this button by the numbers 1 to 5.

Description

The smart radiator thermostat from Tado doesn't work with all brands of radiator valves. Check beforehand which brand of thermostat dial you have. The radiator button from Tado is suitable for faucets from Caleffi, Comap, Danfoss, Giacomini, Herz, Olymp, Siemens, and Terrier.

The Tado Smart Radiator Thermostat (Expansion) is an expansion of the Tado smart radiator thermostat starter kit. Expand the starter kit exactly to your specifications and provide every radiator in your house with a smart radiator thermostat. Thanks to the smart radiator control knob, you can control the radiator via the app on your smartphone. Your smartphone is constantly connected to the radiator thermostat and knows exactly where you are. In this way, the temperature is lowered when you leave and the radiator is automatically set to a comfortable temperature when you come home. Replace your old radiator knob by the smart radiator thermostat and get started right away with the Tado app. Make sure that you have a Tado bridge. Without the bridge, it's not possible to control the radiator thermostat.

    Good product but lacks child lock which is quite annoying.
    • Pros:
      Allow you to control each room individually
    • Pros:
      Open Window Detection
    • Con:
      No child lock
    • Con:
      Can give some wrong temperatures sometimes
    • Con:
      No child lock
    • Con:
      No child lock
    • Con:
      No child lock

    This is a great product, but it lacks the most basic feature for a smart home product: CHILD LOCK.

    If you have a small child or maybe a very curious pet, be aware that you will have problems with them just ramp up the temperature to 25ºC and cook everyone in the room (or dropping to 5ºC and sing "let it go"). This can pose a danger as can cause radiator burns. So keep this in mind.

    The tip for a workaround this is set the manual change of a radiator to 1 min, so any change that your kid or pet do manually rotating the thermostat will only take place for 1 min then go back to the previous setting. But still far from ideal as this feature should be something basic and simple in a smart home product. I had to tape my radiator knob to workaround this efficiently to avoid my boiler turn on and off too frequently.

    You can see users asking for this feature since 2018 on the internet and TADO seems to ignore them giving the same pre-made answers.

    I fully recommend this product for
    • Pros:
      Automatically schedule every room with its own temperature
    • Pros:
      Works with Siri, so just say: ‘make my bathroom 22Cº’ and it’s done! Really great!
    • Pros:
      Great accompanying app
    • Pros:
      Easy mounting
    • Con:
      Makes some noise when turning on or off. Not much, but for sensitive people this might not be nice in the bedroom

    It’s very easy to install, instructions step by step in app. Works right out of the box (make sure you have a tado bridge already installed) Automate your routine and have comfortable temperatures always.

    My best buy of 2020!
    • Pros:
      Really easy to set up
    • Pros:
      Easy to use with the app
    • Pros:
      Good control over the temperature in every part of your house
    • Pros:
      Fits on most CVs and radiators
    • Con:

    Installing the thermostat & radiator-heads where much easier than expected. The whole system worked really well out of the box, with minimal work needed. My gas usage has reduced by almost 30% since I installed the thermostat, whilst keeping the whole house at a comfortable temperature.

    It does what it is supposed to, without over complicating things too much.
