Control the temperature in every room individually

Most homes rely on a single thermostat to control the whole heating system. Even if you turn up the valve on a radiator, it's the main thermostat that decides whether the boiler fires – so that room may never actually reach the temperature you want. tado° Smart Radiator Thermostats solve this. Each room gets its own temperature, its own schedule, and can independently request heat from your boiler via Room Link. Every room reaches the right temperature, at the right time – without heating the ones you're not using.

Frequently asked questions

What does a smart thermostat do and how does it differ from a programmable one?



A programmable thermostat follows a fixed schedule that you set and rarely update. Meanwhile, a smart thermostat lets you control your heating from your phone, integrates with your smart home, and – with tado° AI Assist – adapts automatically based on your location, your habits, and your home's heating behaviour. The result is greater comfort with significantly less energy wastage.

Is it worth switching to a smart thermostat?



Absolutely. For most households, a smart thermostat pays for itself within a few years. The Fraunhofer Institute for Building Physics IBP confirms that smart heating with tado° can reduce your energy consumption by up to 28%⁴. That adds up to significant savings on your annual heating bill, against a relatively modest upfront investment. Beyond the savings, a Smart Thermostat gives you total control of your heating using your phone or voice control via Alexa, Siri, or Google. It also ensures you’re never heating an empty home. If your current heating system runs on a fixed schedule regardless of whether anyone is in, then you’ll notice a massive difference.

Can I control a tado° Smart Thermostat remotely from my smartphone?



Yes. Remote control via the app is included free with every tado° Smart Thermostat. You can adjust your home temperature with more precision, change your schedule, and monitor every room in your home from anywhere. The app is available for iOS and Android.

How much does professional smart thermostat installation cost?



tado° Smart Thermostats are designed for DIY installation. The app guides you through every step using simple, visual guides tailored to your exact heating system. You are done in under an hour at no extra cost. If you're unsure, you can of course also let a professional handle it.

Do I need a wired or wireless smart thermostat?



That depends on your existing setup. If you already have a wired thermostat connected to your boiler, a wired smart thermostat is the easiest replacement. If there's no existing wiring – or you want to place your thermostat wherever you like – a wireless smart thermostat is the better choice. The tado° compatibility checker will identify which works best for your home.

What's the difference between the free tado° app and AI Assist?



Every tado° Smart Thermostat includes remote control, Smart Schedule, smart home and voice assistant integration, and Room Link at no additional cost. AI Assist (from €3.99/month or €29.99/year) automates actions you would otherwise have to do manually – including Geofencing, Open Window Detection, Preheat Before Arrival, Weather Adaptation, Adaptive Heating, Holiday Mode, and full Energy IQ insights. Users with AI Assist save an additional 55% more energy compared to users of the free tado° App.

¹Based on internal data averaged across all tado° customers, collected up to 30/11/2023.

²Up to 55% more savings is based on internal modelling comparing the use of tado° AI Assist vs the free tado° app. Actual savings depend on household characteristics, usage patterns and external factors.

³Actual savings depend on household energy use and may vary. €485 annual savings reflect 22% of the EU average gas heating bill (€2,208) as reported by Eurostat for 2024, based on our user base average. Results may differ.

⁴Based on the Fraunhofer Institute for Building Physics Study: "Dynamic simulation study to compare the energy demand of selected, typical homes with heating control with weather forecast and absence detection versus conventional heating control", 2022 (EER-021/2022/720).

⁵Actual savings depend on household energy use and regional factors. CO₂ savings are based on an average EU household gas heating consumption of approximately 20,000 kWh per year and an emission factor of 0.18 kg CO₂/kWh for natural gas combustion, resulting in estimated savings of up to 790 kg CO₂ annually for a 22% reduction. Data based on Eurostat Natural Gas Price Statistics 2024 and European Heat Pump Association reports. Individual results may vary.

*Only works in homes with their own boiler or heat pump. All radiators must be equipped with tado° Smart Radiator Thermostats.
