Support for Zone Valves and Underfloor Heating: Tado X accommodates various underfloor heating setups. For zone valves or single-zone systems, a Wired Smart Thermostat X or another Wireless Smart Thermostat X Starter Kit can be utilized. It’s important to note that Tado X does not offer a dedicated heating manifold controller for highly complex underfloor heating installations, a feature present in some competing systems like Honeywell Evohome.
Seamless Installation: A DIY-Friendly Upgrade
The installation process for Tado X is designed with the do-it-yourself enthusiast in mind, providing clear, step-by-step instructions tailored to different kit configurations and existing systems. One user’s experience replacing a Honeywell Evohome system highlights the straightforward nature of the installation. The process involved wiring a Wireless Receiver X to replace an older relay unit. A crucial point emphasized during installation is the importance of consulting boiler specifications, as an older setup might have overlooked the benefits of OpenTherm. Utilizing OpenTherm allows the smart heating system to dynamically adjust the boiler’s flow temperature based on heating demand, leading to more efficient gas consumption and potential cost savings.
Once the core receiver is installed and connected to Wi-Fi, integrating the Smart Thermostat X devices is equally simplified. This involves scanning a Matter code on the device and following the intuitive in-app prompts. Tado X thoughtfully includes a comprehensive range of adaptors, ensuring compatibility with most existing radiator valve fittings, thus minimizing the need for specialized tools or parts.
The Tado Smart Thermostat X units themselves are characterized by their compact and modern design, featuring a fixed front-facing screen. During initial setup, users are guided through language selection and can even adjust screen orientation in 90-degree increments, a practical feature for radiators installed at various angles. Following installation, the thermostats undergo an automatic calibration process to precisely determine the range of their flow control pin. A significant improvement over many competing systems is the use of removable, rechargeable battery packs for the thermostats, powered via USB-C. These batteries are estimated to last one to two years, offering a more sustainable and cost-effective solution compared to disposable batteries.
For multi-zone underfloor heating, Tado X employs a similar approach, utilizing a second Wireless Receiver X and a Wireless Temperature Sensor X. The Tado X app intelligently allows users to configure a specific zone, enabling the temperature sensor to activate the zone valve and simultaneously signal the main receiver to call for heat. A minor point of friction identified is the inability to name multiple Wireless Receiver X devices within the app; they are identified by serial numbers. This can present a challenge when adding new devices or troubleshooting, requiring users to accurately identify which receiver controls which zone.
Advanced Features and Responsive Performance
The Tado X app serves as the central hub for managing the entire heating system, building upon the user-friendly interface of its predecessor. The app allows for the creation of custom schedules for each room, with distinct time slots and target temperatures for different parts of the day. These schedules can be easily copied and adapted across multiple days and rooms, streamlining the configuration process.
Beyond basic scheduling, Tado X offers a suite of advanced features designed to optimize comfort and energy efficiency. The Geolocation skill, part of the optional Auto-assist subscription (£29.99 annually or £3.99 monthly), enables automatic heating adjustments based on household members’ presence. When the last person leaves, the heating can be automatically turned off, and as the first person approaches home, it can pre-heat the house, eliminating the need for manual intervention and preventing energy wastage. Without a subscription, users receive a notification prompting them to manually adjust the heating.
The Auto-assist subscription also includes Open Window Detection. This intelligent feature monitors for rapid temperature drops, indicating an open window or door, and automatically shuts off heating in that specific room to conserve energy. While generally effective, the system can occasionally be triggered by sudden temperature changes, such as opening a bathroom door after a shower. Users can easily override false alerts, ensuring continuous comfort.
Adaptive Heating, a relatively new addition, employs AI to learn how individual rooms heat up and cool down. This data is used to precisely time heating activation and deactivation, preventing over- or under-heating and maintaining a consistently comfortable environment. The system requires a learning period, during which minor temperature fluctuations might occur, but it generally performs exceptionally well.
Recent updates have introduced features like Adaptive Heating for specific heating types, allowing the Wireless Receiver X to better control heat output, which is particularly beneficial for slow-responding systems like underfloor heating. Hydronic Balancing is another significant enhancement, automating the adjustment of water flow to radiators to ensure even heating across the entire system, a task that previously required professional intervention. Weather Adaptation, which actively uses weather forecasts to pre-emptively adjust heating, further contributes to maintaining optimal home comfort.
Manual overrides are readily available through both the app and directly on the smart TRVs. From the app, users can adjust room temperatures for a specified duration, until the next scheduled change, or permanently. The system remembers the last setting, and changes are reflected almost instantaneously, a clear demonstration of Thread’s low latency. Direct adjustments on the TRVs, by turning the outer dial, offer convenient on-the-spot control. Users can configure whether these manual overrides expire after a set time or at the next scheduled change, a feature that helps manage household energy consumption, especially with children or guests. The Tado Smart Radiator Thermostat X TRVs are notably quiet in operation, a significant improvement over older models.
The Wireless Temperature Sensor X, powered by three AAA batteries, offers simple manual temperature adjustments via its arrow keys. While the TRVs’ built-in sensors are generally accurate, the addition of a Wireless Temperature Sensor X can provide more precise readings in rooms where placement might be suboptimal.
