Looking for an efficient way to heat your home and reduce your energy bills? Smart radiator valves offer the perfect solution. These innovative devices allow you to precisely control the temperature in every room, even remotely. In this article, we discuss the top 3 smart radiator valves of the moment and provide useful tips to make the right choice for your home and heating system.
What is a smart radiator valve and what is it for?
Smart thermostatic valves, also called smart thermostatic heads, are installed on radiators and allow you to remotely, using software, adjust the flow of hot water that heats the thermal device.
We are usually used to seeing traditional thermostatic valves installed in radiators, which allow you to control the temperature in a static way, that is, they cannot change their behavior when the climate and environment change. The classic thermostatic valves, therefore, once set manually, via the scale, are “set” to a certain temperature, until the setting is changed.
Otherwise, the innovative smart thermostatic valves offer you the possibility to control the temperature of the radiators in an intelligent way; in this way, through specific software or an ad hoc app, you can set different temperatures for the different rooms of the house and you can ask the Wi-Fi thermostatic valve to turn on or off or change the temperature depending on the time of day or other environmental factors.

How does it work?
The smart thermostatic valve works through a motor, which contains a specific thermostatic fluid, and can also be managed remotely, completely autonomously. Once the settings have been adjusted to your specific needs, the valve does everything by itself, without you having to adjust it manually every time.
These devices can be connected to the home automation system, which can be managed remotely via smartphone, tablet, smartwatch and PC; the aim of the manufacturers of these devices is to bring to the market products that can meet the specific needs of each one, thus limiting the waste of energy and the economic waste that occurs with classic thermostatic valves.
The smart software for managing thermostatic valves monitors all energy consumption, so that you can view waste with simplified details and graphs.
The valve system also sends you notifications, via smartphone and email, to warn you if a critical temperature is reached, or if the radiator is defective or not working properly.
Some products on the market are supplied in a kit that also includes a smart Wi-Fi thermostat.
How do you install a smart radiator valve?
Installing a smart radiator valve is easier than you might think and can be done without the help of a professional in most cases. Here is a step-by-step guide to help you through the process:

In short, a smart radiator valve provides more control, more comfort and lower energy costs, making it a smart investment for any household.
Compatibility with heating systems
Before you purchase a smart radiator valve, it is important to know whether it is compatible with your existing heating system. Not all smart radiator valves will automatically fit every radiator or type of heating system. Here are some important considerations to keep in mind when assessing compatibility:
- Thermostatic radiator valves: Smart radiator valves are designed to work with thermostatic radiator valves. If your radiator has a manual valve (which doesn’t have temperature control), you’ll probably need to replace it with a thermostatic valve before you can fit a smart valve.
- Valve thread size: The thread on your radiator valve must be compatible with the smart valve. Most manufacturers supply adaptors for different thread sizes, but it’s a good idea to check the size of your valve to ensure the smart valve will fit.
- Heating system type: Smart radiator valves are generally compatible with central heating systems that use radiators to distribute heat around the home. For specialist systems, such as underfloor heating or decentralised heating systems, smart radiator valves may be less effective or even unsuitable.
- Home automation and smart home systems: Already set up a smart home? Check that the smart radiator valve is compatible with your existing smart home platform, such as Google Assistant, Amazon Alexa or Apple HomeKit. This will allow for seamless integration and ensure you get the most out of all the smart features. Adapters and accessories: Many manufacturers supply smart radiator valves with a set of adapters, so that they can be fitted to different radiators. Always check that the correct adapter for your type of radiator is supplied or available.
By considering these factors, you can ensure that the smart radiator valve is compatible with your system and functions well within your existing infrastructure.
Main functions
Temperature per radiator
It is useful to be able to control the temperature per radiator or per room. For example, if you work in your office and not in the living room, then the living room does not need to be heated.
Connect it to other devices
It is useful if thermostatic valves can be connected to a thermostat, but also to other devices. For example, radiator valves respond to window sensors. If a window is open, the radiator valve knows this and will not increase the temperature unnecessarily.
Useful functions include:
Smart radiator valves can include functions such as geofencing. Geofencing is a function that allows the thermostat to know when someone is or is not at home. This helps prevent the heating system from running unnecessarily and ensures that you always come home to a warm house.
Temperature per room
Smart thermostats that can be programmed for each room allow users to adjust the temperature to their own preferences. Typically, a thermostat is placed in the living room, to which all radiators are connected. Once the desired temperature in the living room is reached, all radiators turn off; however, with a smart radiator valve that can be programmed for each room or zone individually, users can adjust the temperature to their own preferences.
Energy savings
Smart radiator valves, such as those from tado°, can reduce heating bills by 30%. They can often pay for themselves within a year. That’s good for the environment and good for your wallet.
Smart home features
Firstly, features are important when buying a smart radiator valve. If you want to be able to control your smart thermostat from a smartphone and/or adjust the temperature using voice control, it’s best to buy one that is compatible with a smart home platform. It’s also good to look for the ability to detect environmental factors. For example, the tado° Smart Radiator Button measures humidity, detects an open window and can be paired with geolocation. You also have the option to let your smart thermostat knob respond to weather forecasts and set smart schedules.
The advantage of a smart radiator valve
A smart radiator valve offers several benefits that contribute to a more comfortable and energy-efficient home. Firstly, it enables precise temperature control in individual rooms. Users can set specific temperatures for each room, depending on their needs and preferences, resulting in a more pleasant indoor climate.
In addition, a smart radiator valve can save energy. By only switching on the heating in rooms that are being used, and not in unused spaces, energy consumption can be significantly reduced. This is not only good for the wallet, but also for the environment.
Another advantage is the ability to control the heating remotely via a smartphone or other smart device. This means that the heating can be adjusted even when the user is not at home, contributing to both convenience and energy efficiency.
Most smart radiator valves also offer integration with other smart home systems and can respond to voice commands via assistants such as Google Assistant or Amazon Alexa. This increases ease of use and efficiency in everyday life.
Finally, some smart radiator valves can learn from the user’s behaviour and preferences, becoming increasingly efficient at regulating the temperature over time, without the user having to make manual adjustments
Can a smart radiator valve be installed on any radiator?
A smart radiator valve can be installed on most, but not all radiators. Compatibility depends on a few factors:
- Radiator Valve Type: Smart radiator valves are generally designed to fit standard thermostatic radiator valves. If your radiator is fitted with a standard manual valve (without thermostatic control), you may need to replace the valve or use an adaptor to fit the smart valve.
- Adaptor Sizes: Many smart radiator valve manufacturers supply a range of adaptors to ensure their products fit different types and sizes of radiator valves. It is important to know the size and type of your current radiator valve to choose the right adaptor.
- Radiator Design: In some cases, the design of the radiator itself can be a barrier to fitting a smart radiator valve, for example if space around the valve is limited.
- Heating System: In most central heating systems, it is possible to fit smart radiator valves. However, in some specialist systems, such as some types of underfloor heating, smart radiator valves may be less effective or even unsuitable.
It is always a good idea to check the specifications of the smart radiator valve and the characteristics of your current heating system and radiators before purchasing. If necessary, you can seek advice from a specialist or directly from the manufacturer of the smart radiator valves.
Does a smart radiator valve fit my heating system?
Whether a smart radiator valve will fit your heating system depends on a number of factors:
- Type of radiator valve: Most smart radiator valves are designed to fit standard radiator valves. If your radiators have thermostatic radiator valves (with a dial to adjust the temperature), then there is a good chance that a smart radiator valve will be compatible. For radiators with manual valves (without temperature adjustment) you may need an additional adaptor or a complete replacement of the valve.
- Thread size: The thread size of your current radiator valves is also important. Most smart radiator valves will fit the usual sizes, but it is always a good idea to check. Many manufacturers supply adaptors for different sizes.
- Compatibility with your heating system: If your heating system has a centrally controlled boiler, you should check that the system supports individual room control. In systems with underfloor heating, smart radiator valves may be less effective unless each zone can be controlled separately.
- Smart home system: If you already have smart devices in your home, such as a smart home hub, it is useful to check that the smart radiator valve is compatible with this system. This ensures seamless integration and operation.
It is always advisable to contact the manufacturer or a specialist prior to purchase for advice on compatibility with your specific heating system.
