How to make it cozy and warm smartly 

On a cold winter's morning, you stick your toe out of bed and land on a warm floor. Because your smart home has already automatically adjusted the underfloor heating to your preferences. We reveal how you can control the underfloor heating.

How does underfloor heating control work?

A room thermostat is used to control the underfloor heating. It measures how warm or cold it is in the room. It has a temperature sensor for this purpose. The thermostat then transmits the values to the heating system, which adjusts the heating output accordingly. This gives instructions to the actuators that open or close the heating circuits. 

To utilize the underfloor heating as efficiently and energy-savingly as possible, the Building Energy Act (GEG) stipulates that the temperature must be controlled on a room-by-room basis. This requirement can be easily met with the smart Shelly components.  

What components are needed to control the underfloor heating?

The type of control depends on the underfloor heating system installed. For example, it is possible to set the heating output via a manual controller or via the system itself. With Shelly, you don't have to keep running down to the basement or get up and operate all kinds of controllers - you program everything automatically, inform your voice assistant that you're too cold, or use the Shelly app from the comfort of your sofa. We'll tell you what you need.

Control underfloor heating with the Shelly Wall Display

If you want a central location in your home to control your underfloor heating, the Shelly Wall Display is just what you need. The control panel for your smart home offers a 4-inch screen on which you can not only control the networked scenes and intelligent schedules of your smart devices but also monitor energy consumption. It also shows you the temperature and humidity in the room when it is connected to the Shelly BLU H&T sensor. The display serves both as a control unit for Shelly devices and as a replacement for the conventional room thermostat (RTR).

Controlling water-based and electric underfloor heating

To be used as a room temperature controller, the Shelly Wall Display requires three connections: L, the conductor that carries the current; N, the neutral conductor, and O, the switched wire to control the heating. The maximum switching load of the device is 5 amps, which is approx. 1,150 watts. It can therefore control both water-based underfloor heating systems with 230 volt actuators and electric heating systems. If you need more than 5 amps, you can combine an additional relay.  

If it is not possible to replace the RTR in your underfloor heating system, you can also install another Shelly actuator behind the existing RTR as a switching module - for example the Shelly 1 Gen3, 1PM Gen3 or Pro 1 or 1PM. But more on this later. 

Shelly BLU H&T as a room thermostat

The Wall Display works perfectly with the Shelly BLU H&T. The Bluetooth temperature and humidity sensor provides instant environmental data and acts as a smart room thermostat. This allows you to adjust the rules for controlling your underfloor heating even more precisely to the conditions in the room and not only ensure cosy warmth, but also a good indoor climate. After all, correct heating is not only cozy but also prevents damp walls or even mold growth. The small sensor has a battery life of up to three years.

Can also be used without wall display

You can also use the measured values from the Shelly BLU H&T without the Wall Display to control the underfloor heating. For example, in combination with the Shelly 1 Gen3. It acts as an actuator for the actuators of a water-based underfloor heating system or controls the operation of the heating mats of an electric underfloor heating system. The BLU H&T then provides the necessary information for smart control. It regulates the control via actions, scenes, or the virtual thermostat in the Shelly app. So if it is too cold in the room, the smart home tells the Shelly 1 Gen3 to turn up the heat output so that you don't get cold feet.

Smart actuators control heating circuits and can be retrofitted

In addition to the Shelly 1 Gen3, there are several other smart actuators that can be used to control the underfloor heating. They can be used both in conjunction with a smart room thermostat such as the BLU H&T and with conventional RTRs. Retrofitting smart components for your underfloor heating is therefore no problem. Let's take a look at the various Shelly actuators.

Shelly 1 Gen3

The Shelly 1PM Gen3 is a WLAN-controlled smart switch with a maximum switching load of 16 amps. Its range of functions also includes power monitoring. It saves the measured values in the free cloud to optimize power consumption. For example, you can analyze how much electricity your electric underfloor heating consumes. The switch offers a high level of security and also serves as a range extender and Bluetooth gateway for other Shelly devices. You can extend the functionality of the Shelly 1PM Gen3 even further by adding an add-on - for example, a temperature sensor or a humidity meter. You can install the Shelly 1PM Gen3 behind switches, and sockets, in flush-mounted boxes, or directly in the heating circuit manifold.
