What are the main benefits of installing a Smart Thermostat?

Upgrading to a Smart Thermostat completely changes the way you interact with your heating. Whether you're replacing a basic dial, a digital room thermostat, or a programmable timer – a Smart Thermostat is a huge advancement. It connects your heating to your phone or even your smart speakers, and it has the potential to learn, getting smarter and better over time as it picks up your habits.

Here’s what changes the moment you start using a tado° Smart Thermostat:

Control from anywhere

Adjust your heating from your smartphone, wherever you are.

Smart heating schedules

Set different temperatures for different times of day in each room.

Works with your smart home

Connect Smart Thermostats to the smart home platforms you already use.

Voice control

"Alexa, set the living room temperature to 20 degrees." Done.

Real time insights

Monitor your heating remotely and get an overview from anywhere.

Lower bills

Smart Thermostats use less energy and reduce your heating bills.

Why tado°? So your heating can think for itself

Any smart thermostat is already an upgrade compared to a standard dial, but there is a variety of models to choose from, each of which have a different set of features. tado°, for example, includes many of the benefits we've already mentioned, such as remote control via our app, Smart Schedules, full smart home and voice assistant integration via Matter, Multi-Room Control, Room Link, and of course step-by-step DIY installation guides. You also get precision no standard thermostat can match – down to 0.5°C.

Getting started is easier than you think

Wondering how to install a Smart Thermostat without a professional? You’d be surprised how simple it is:

1. Find your setup

Start with a Smart Thermostat to control your boiler or underfloor heating, or add Smart Radiator Thermostats to one or more rooms.

2. Install it yourself in under an hour

The tado° App guides you through every step using visual guides. No technical experience needed.

3. Start saving from day one

tado° helps you save energy straight away. You can set schedules that fit your routines and control your heating remotely from your phone.

4. Expand when you're ready

Add tado° devices to more rooms for greater control and savings. When ready, upgrade to AI Assist and let tado° handle everything automatically.

Find your Smart Thermostat

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.

All your questions answered.

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. £244 annual savings reflect 22% of the average UK household gas heating bill (£1,109) for 2024, based on our user base average. Source: Ofgem, "Energy Consumer Archetypes Update 2024" and UK Department for Energy Security and Net Zero official statistics. 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 UK household gas heating consumption of approximately 13,600 kWh per year and an emission factor of around 0.17 kg CO₂/kWh, leading to estimated savings of up to 500 kg CO₂ annually for a 22% reduction.
