Heating Control 2022: The Best Smart Thermostat for Home

Which best Smart Thermostat for Home is the right one for me and how much does it cost? If you deal with this or similar questions, you will quickly come across a huge selection of smart retrofit solutions. We help to find the heating control that suits your budget and structural requirements. We also reveal which brand convinced us in the test.

As long as it is comfortably warm, hardly anyone deals with their heating system. But at the latest when temperatures drop and heating costs rise, many people start thinking about a new heating system. But how do smart heating controls differ from conventional control systems?

What is a heating control?

As its name suggests, a regular heating control is used to regulate individual heating elements such as boiler, radiator, or room thermostats uniformly and thus saves constant manual adjustments. Via the heating control, e.g. B. lower the temperature in all rooms at night. There are three main types of heating controls:

  • Mechanical heating control: This classic is installed in most households and can only be operated manually
  • Wireless thermostats: Can be operated via the app, some are also compatible with popular voice assistants
  • Intelligent thermostats: Can be operated via app or voice and also interact with weather apps, motion detectors, and many other smart home components. With a smart heating control, the temperature can be regulated from anywhere

How does the best smart thermostat for home work?

A smart heating control expands the basic functions of a classic heating control with even more operating options. Because their greatest advantage lies in the combination of automatic processes (e.g. through heating plans) with flexible operating options via app or voice.​​​​​​

The three advantages of a smart heating control are

  • Energy efficiency: Some smart thermostats use geofencing to detect the absence of residents and adjust the temperature accordingly. In combination with sensors, the heating control even automatically registers open windows and closes the valve during ventilation.
  • Comfort: Thanks to the app or voice control, nobody has to get up from the sofa to adjust the temperature.
  • Safety: By integrating it into a smart home system, the heating can e.g. B. be quickly deactivated in the event of a fire to prevent serious damage. In the event of a long absence, it also automatically switches to frost protection mode if necessary.

How can a normal heating control be controlled remotely?

Beginners have three options to choose from for retrofitting, with which they can retrofit their home smartly. The conversion of classic radiators is associated with the least effort, the greatest is the installation or retrofitting of underfloor heating.

Possibility 1: Smart Retrofitting of Radiator Thermostats

Mechanical thermostats or radiators in the living room can be easily replaced with wireless thermostats for control via the control center in the living room or with smart thermostats that can be controlled from anywhere. Both retrofit solutions have the advantage that they can also be installed by people with little prior technical knowledge.

Advantages Disadvantage
  • Easy to install
  • Compatible with almost all radiators
  • suitable for rental apartments
  • Comparatively cheap
  • optionally available with an app and  voice control
  • e.g. B. can be combined with wall thermostats
  • Some models require the purchase of an additional smart home center from the manufacturer
  • with many thermostats, the retrofitting costs can add up significantly

We rate this retrofit solution as the easiest and recommend it to all Smart Home beginners.

Radiator thermostats – A Distinction Between Individual Control and System

If you want to smartly retrofit your radiator thermostats, you have to decide between individual radiator thermostat control or a radiator thermostat system.

Radiator Individual Thermostat Control

Individual thermostat control for radiators is the cheapest form of retrofit. The heating plan is created directly on the thermostat via a digital display or via a Bluetooth app. If it is a Bluetooth-enabled radiator thermostat, the temperature can be controlled via a smartphone app. Because of the limited radio range, however, the user must be in the same room almost all the time. Location-independent access is also not possible.

Possibility 2: Replace Classic Room Thermostats

There are two subtypes of intelligent wall or room thermostats:

  • Wired room thermostats (for the wall):  Smart room thermostats with a wire should be installed by a professional, otherwise there is a risk of electric shock.
  • Wireless room thermostat (for the wall): A mobile connection is also possible here. The manufacturer Google Nest offers e.g. B. a wireless module, its competitor Netatmo a relay to network the wall module with the boiler. Tenants should definitely speak to the owner before installing this solution, as the relay or radio module replaces the previous wall thermostat. Wiring is also required here, which establishes the connection to the thermal bath and switches it on or off.

If both room and radiator thermostats are to be used, both must be exchanged for compatible cable or wireless alternatives. Users should choose a provider here since both types of controllers connect to the same Smart Home control center from the manufacturer. The providers include Google Nest With Auto-Schedule, the Google Nest Learning Thermostat learns from you, and the programs themselves.

Advantages Disadvantage
  • Convenient screen
  • Optionally available with works with Alexa
  • 3rd Generation Nest Thermostat

  • Easy installation

  • Remote control
  • Almost all models require an additional smart home center from the manufacturer
  • Installation requires prior knowledge
  • Agreement with landlord necessary

3rd Option: Upgrade Boiler-Bound Heating Systems or Old Underfloor Heating Systems

If there is no radiator or room thermostat, e.g. because the (old) heating is controlled via the boiler, retrofitting via a radio relay is usually possible. This is connected to the boiler and networked with other heating elements. You can find out whether your heating system is suitable for this, e.g. Electric Radiant Floor Heat Heating System with Aube Digital Floor Sensing Thermostat

Incidentally, this also works with classic underfloor heating systems. Alternatively, the entire underfloor heating can be replaced with a smart variant. However, since this retrofitting method is by far the most complex, we have dedicated our own underfloor heating guide to it, in which we present various manufacturers and retrofitting options.Table could not be displayed.

advantages disadvantage
  • Saves space in tight living spaces
  • Particularly popular with new builds
  • Retrofitting is comparatively complex and expensive

Control Heating Intelligently – How To Proceed

  1. Determine the basic requirements: Check how your current heating system works and, above all, where it can currently be controlled (on the radiator thermostat, using the room thermostat in a room, or just on the boiler). It depends on which retrofit solutions come into question.
  2. Select-control type: Consider whether your smart heating control should only be operated automatically via schedules, via the app, or also with voice commands.
  3. Define budget: Now it is a matter of determining how much the heating control may cost. We recommend all interested parties with a low budget choose a modular system that can be gradually supplemented with additional components.
  4. Select products: Select the individual components that best meet your needs. Our expert guide to WLAN thermostats for radiators or room thermostats (for boiler control) offers assistance. Important: While radiator thermostats are standardized and therefore usually fit almost anywhere, you should check the compatibility of wall-mounted room thermostats with existing heating elements on the manufacturer’s website (this is possible with tado° and Netatmo, for example) or ask them.
  5. Installation: Smart radiator thermostats can usually also be installed by users without technical knowledge. Smart wall thermostats or underfloor heating, on the other hand, require significantly more extensive structural interventions and should therefore be installed by an expert. If necessary, their installation should be clarified with the landlord/homeowner.

Recommendation: Google Nest is the all-Rounder for Homes and Rented Apartments

Both the intelligent Google Nest radiator and room thermostat can be networked with the weather forecast and even react to it. This function is particularly energy-saving in heavily insulated new buildings or houses with underfloor heating.

In everyday life, the smart Google Nest radiator heating control automatically increases the temperature slowly and continuously, so that the desired temperature is reached in an energy-saving manner, especially when the outside temperature is constant. The Google Nest radiator heating control can even learn how much heat the residents want and then automatically ensures comfortable temperatures. With additional thermostats, users can set up individual heating zones that can be controlled independently of one another.

Beginners can choose from an inexpensive starter kit, which includes a “bridge” for the Internet connection. In this way, the heating thermostat can also be controlled with a smartphone and can be networked with Amazon’s voice assistant Alexa if desired. Last but not least, theGoogle Nest radiator devices are compatible with almost every classic heating system.

The Google Nest radiator rental set is also an interesting alternative to purchasing. This is particularly interesting for users who do not want to carry out a permanent installation. The rental package is also suitable for anyone who just wants to try out the Google Nest radiator thermostat including internet connection and radio.

Editor’s assessment: The Google Nest radiator heating system has been in daily use for a long time in one of our test households. It convinced us with its easy handling and high level of comfort. We currently have schedules to ensure the perfect room temperature, and Alexa is used for spontaneous change requests. She then comments on the command “Alexa, I’m cold” with “You’re about to get warm” and increases the temperature to a predetermined value.

We only find it a bit unfortunate that a subscription has to be taken out for some premium functions such as geofencing in order to be able to use them. So far, however, the normal functions have been sufficient for us.

What heating control alternatives are there?

For those whose needs the Google Nest radiator heating control does not meet, there are two good alternatives. Both have a very large product portfolio and are also Alexa compatible.

An overview of other ways of saving heating costs

In the smart home, the networked devices automatically exchange data in order to optimize each other. So For example, a window sensor recognizes when it is opened and informs the central office, which then adjusts the heating output accordingly. The intelligent home also uses a sensor to notice when its occupants are absent and automatically switches off all devices that are not required. In addition, spontaneous changes are possible on the go, e.g. the activation of the frost protection mode from the skiing holiday. If you are particularly cold after a long winter walk, you can use the app to set a particularly cozy temperature on the way home. Likewise, z. B. Disable forgotten lamps from the office. This not only reduces heating costs but also electricity costs.

Tip: If the networking measures are to be particularly comprehensive, it may well be worth considering using a professional service provider who will quickly implement the networking of the individual components and offer support in the event of potential problems.

How much does a heating control cost?

The prices of smart home heating controls can be divided into three categories: adjustable thermostats, app heating controls, and heating controls with voice control.

Standard heating control: The cheapest is simple thermostats that work on schedules instead of an app. Already for less than 16 dollars. –>Inkbird ITC-1000F 2 Stage Temperature Controller Cooling and Heating Modes Celsius and Fahrenheit

App heating control: The costs for thermostats with a smartphone connection are somewhat higher. They are offered 50 dollars. e.g. If, for example, you buy a Centralite Pearl Thermostat (Works with SmartThings, Spectrum, Cox, Time Warner Cable, Vera, and ZigBee Platforms).

, you can connect it directly to your FRITZ! Box home network and operate it via its web interface or app. Room or wall thermostats with an app, on the other hand, are significantly more expensive.

Heating control via app and voice commands: Smart thermostats with an app connection and an additional voice control option are available for 100 dollars and above. Owners of an Echo Show 2 or Echo Plus speaker can e.g. B. operate the Eurotronic Spirit thermostat directly with Alexa voice commands. In this case, it is not necessary to buy a smart home control center from the manufacturer. The same applies here: Smart wall thermostats cost significantly more than retrofit solutions for radiators.

The total costs of the smart heating control depend on how many room or radiator thermostats are required and whether the selected model also requires a smart home control center from the manufacturer.

Expert tip: It is often cheaper to buy a starter set and add individual components to it than to purchase each module separately.

​What are the best heating control systems?

If you are looking for smart heating control, you should shortlist the following models:

What is a heating control?

The term heating control refers to smart devices that regulate the temperature intelligently and thus save energy and costs. In most cases, radiator thermostats are used, which are attached to the radiator valve, or room thermostats, which are connected to an individual theme.

How much does a heating control cost?

How much does a heating control cost? The costs for a heating control vary depending on the effort. The installation costs about 30 euros. There are also travel and material costs. Programming costs are also not included in the price. Since changing the valve on a radiator is not difficult and can also be carried out by a layman, it is worth doing the work yourself. A simple valve with smart functions and app control.

How does a heating control work?

How does heating control work? The principle of how a heating control works are simple. The room temperature or the actual value is compared with the target value or the desired temperature via a temperature sensor. If the actual value is greater than the target value, the valve on the radiator is closed or the burner is switched off and vice versa. The desired temperature is continuously readjusted through constant comparison.

How can I control my heating?

The easiest way to control a heating system smartly is with a smartphone app. To do this, the radiator thermostat connects to a smartphone via Bluetooth and the user can make the settings via the app. Inexpensive individual solutions, such as the Eqiva radiator thermostat, are already available for around 50 dollars.

What is the best smart thermostat for the home controller?

The best smart thermostat for home controllers are usually part of modern heating systems and are also called room thermostats. They are usually permanently installed on the wall and connected to the burner. Unlike a heating thermostat, they are not attached to the radiator and so measure the temperature of the room in which they are attached.

Why do you need a heating control?

Due to the constantly rising energy prices, smart heating controls are a good choice to reduce energy consumption and heating costs. This is mainly achieved through heating plans, such as automatic temperature reduction at night or in-office hours. But the intelligent detection of whether a window is open also contributes to this. If the radiator thermostat or room thermostat supports the function, the temperature is reduced during ventilation times.

What are the advantages of smart heating control?

  • Reduction in heating costs
  • Economical use of energy
  • relief for the environment
  • Increased comfort

What are the disadvantages of smart heating control?

  • The relatively high initial investment
  • Area of ​​application limited by WLAN radio range

How does a radiator thermostat work?

A best smart thermostat for home radiator thermostat, the mechanical control unit is replaced by the electrical radiator thermostat. Inside there are usually one or two temperature sensors. These measure the room temperature. The desired temperature is defined via the app. If the room temperature is above the desired temperature, the valve is closed. If the desired temperature is above the temperature, the radiator valve is opened. A heating plan can be defined for each day in the app. For example, the user can specify that the temperature should be raised to 22 degrees after getting up in the morning, then lowered again while leaving home and raised again in time for coming home.

Which heating control systems are there?

Radiator thermostat: A radiator thermostat is used when there is a collective heating system in the house and e.g. B. is only radiators where the temperature is set.

Room thermostat: A room thermostat is usually found in apartments that are heated with an individual gas boiler. So every rental apartment has its own thermal bath, with which the rooms are heated. There are usually room thermostats on the walls, which are used to regulate the temperature.

Open Therm Thermostat: Open Therm is a protocol used in modern heating systems. It enables a mixed form of collective heating system and room thermostat.
