You might want a warm bathroom first thing, a comfortable home office during the day and a cooler bedroom at night. Smart radiator valves let you set different heating schedules for each room, giving you more control over when and where you want warmth.
We’ve picked six of the best smart radiator valve options, from starter kits to add-on valves for systems you already own. We’ll explain what each needs to work, including whether it can simply control a radiator or also tell your heating system to turn the boiler on. If you’re new to the technology, our smart radiator valve buying guide explains the basics.
Our six picks
For a new smart radiator setup
For an existing Wiser home
For simple room scheduling
For a compatible smart home
For a Thread-based setup without a subscription
For an existing Hive system

| Kasa KE100 KIT with KH100 hub | One valve + KH100 hub | For simple room scheduling | None for app scheduling. This kit cannot call for boiler heat. |
| Aqara Radiator Thermostat W600 | One valve | For a compatible smart home | Aqara Zigbee hub for Aqara app schedules, or a Matter controller and Thread border router for Thread mode. |
| Eve Thermo Matter, 5th generation | One valve | For a Thread-based setup without a subscription | Compatible Matter controller and Thread border router. |
| Hive Smart Radiator Valve UK7004240 | One valve head | For an existing Hive system | Current Hive Hub; Hive Active Heating for Heat on Demand. |
These are different buying routes, not six interchangeable heads. Check the current retailer price for the exact kit or pack, then add the cost of any hub, boiler controller, extra valves, installation and optional service you actually need.
The picks in detail
For a new smart radiator setup
1. tado° Smart Radiator Thermostat X Starter Kit with Bridge X
The kit gives you an X radiator head and Bridge X, so it is a starting point for room scheduling without buying a separate Thread bridge. You can add more X valves later. If you want a room to turn the boiler on when it needs heat, budget for a compatible tado° X wired thermostat or wireless receiver setup as well. The X range does not join an older tado° V3+ installation.
Choose it if: You are starting a tado° X system and want the bridge included.
Bear in mind: The Bridge X is not a boiler controller; check the full heating-system plan before ordering.
Check the manufacturer’s setup guidance for the exact system requirements.
For an existing Wiser home
2. Drayton Wiser 2nd Generation Radiator Thermostat, 3-pack
Three matching heads make sense if you already have Wiser controlling the heating and want to extend room-by-room control. Drayton says its second-generation heads work with both first- and second-generation Wiser hubs. The pack is not a complete heating system: there is no hub or boiler controller in the box.
Choose it if: You already use Wiser and have three compatible radiator positions to add.
Bear in mind: Confirm your radiator valve bodies and existing Wiser setup; this pack is not a starter kit.
Check the manufacturer’s setup guidance for the exact system requirements.
For simple room scheduling
3. Kasa KE100 KIT with KH100 hub
This kit includes a KH100 hub and one KE100 radiator head. That is a straightforward way to schedule one radiator, then add compatible heads later. Its hub links the valves to the Kasa app; it does not replace the device that switches your boiler on. The room can receive heat only when your main heating is running.
Choose it if: You want app scheduling without changing boiler controls.
Bear in mind: It does not make a room independently call for boiler heat. Check the supplied adapters against your valve body.
Check the manufacturer’s setup guidance for the exact system requirements.
For a compatible smart home
4. Aqara Radiator Thermostat W600
The W600 gives you a choice between Matter over Thread and Aqara Zigbee. In Thread mode it can join a compatible smart-home platform with a Matter controller and Thread border router. For Aqara’s own detailed schedules and sensor-linked features, check the Zigbee mode and compatible Aqara hub. The on-valve dial is useful when you are in the room.
Choose it if: You already have a compatible Thread or Aqara setup and value that flexibility.
Bear in mind: Some features depend on the network mode; it does not itself control a boiler.
Check the manufacturer’s setup guidance for the exact system requirements.
For a Thread-based setup without a subscription
5. Eve Thermo Matter, 5th generation
Eve Thermo is a neat option if you already run a Matter-over-Thread home. Eve says its schedules are stored on the device and its features do not require a subscription. It offers on-device touch control too. The valve still needs a suitable Thread border router and platform hub for connected setup, and it should not be mistaken for a boiler controller.
Choose it if: Your smart home already has the right Thread hub and you prefer no recurring feature fee.
Bear in mind: Check your exact platform and border router before buying; no boiler control is included.
Check the manufacturer’s setup guidance for the exact system requirements.
For an existing Hive system
6. Hive Smart Radiator Valve UK7004240
This is the add-on to consider if you already have a compatible Hive Hub. You can set radiator schedules in the Hive app. With Hive Active Heating, Hive says its Heat on Demand feature can link valve demand to the thermostat and turn heating on; without it, the valve only regulates its radiator while the heating is already on. Plumbworld currently offers the exact UK7004240 head, not a new valve body.
Choose it if: You already have a compatible Hive Hub, especially alongside Hive Active Heating.
Bear in mind: Hive Hub 1 is not supported. Check that the existing radiator has a compatible thermostatic valve body.
Check the manufacturer’s setup guidance for the exact system requirements.
Plan the full cost, not just the first valve
For one room, price the valve plus the hub or Thread border router if you do not own one. For three rooms, check whether a multi-pack covers all three radiators and add any boiler controller needed to make those rooms call for heat. For five rooms, add enough separate valve heads for every radiator you want to control—not just one per room if a room has two radiators. Then compare any optional subscription and installation cost over a year, not only the checkout total.
A starter kit may look dear beside a single head because it contains a bridge or hub. Equally, a three-pack can look good value but is no use on its own without the right Wiser system. Do not treat a promised energy saving as a guaranteed payback; your heating pattern and existing controls matter.
How we chose these valves
We compared the exact available variants by what each box includes, which hub or heating system it requires, whether it can participate in boiler heat demand, the way you adjust it, and the likely cost of expanding to several radiators. We checked current product availability and manufacturer setup guidance. These picks are based on manufacturer and retailer information, not hands-on testing; we have not measured battery life, app reliability or energy savings ourselves.
If you are choosing between a room valve and a central control, read our smart radiator valves vs smart thermostat guide. Boiler wiring and valve-body replacement are different jobs: follow the product instructions and use a qualified heating or electrical professional where the work requires one.
Frequently asked questions
Can a smart radiator valve turn my boiler on?
Not necessarily. A valve head controls one radiator; whether it can request heat depends on a compatible thermostat or boiler controller and the way that system is configured. Check the exact ecosystem before buying.
Do I need a hub for smart radiator valves?
Often, but the type varies. Some use a brand hub, while Matter-over-Thread valves need a compatible controller and Thread border router for connected features. A hub is not automatically a boiler controller.
Can I fit one to any radiator?
No. Check that the radiator already has a compatible thermostatic valve body and compare its thread or required adapter with the manufacturer’s guide. If the valve body itself must be changed, ask a qualified heating professional.
Will smart radiator valves save money?
They can make it easier to avoid heating an unused room, but no saving is guaranteed. Include the cost of hubs, controllers, extra heads and optional services when deciding whether the change is worthwhile.
