The Best Smart Home Heating: Our Picks

Guide: Questions you should ask yourself before buying Smart Home Heating

What is Smart Home?

Smart Home is the new living space in which all technical systems are networked and can be controlled with voice assistants or remote controls.

Thanks to the central control, all recurring processes can be automated and coordinated with each other.

A considerable relief that makes living more comfortable and also works efficiently and economically.

How does a smart home heating system work?

One of these technical systems that can be networked and controlled via the smart home is the heating system.

The smart home heating can be switched on time-controlled by smart thermostats, so that a person already has a temperature-controlled room before entering.

The heating also regulates itself automatically when a window is opened so that heating is not unnecessary and energy costs are saved.

Through more complex solutions, in addition to the rigid time control and the simple "window open" detection, it is also possible to detect the presence of people and only heat when a person is at home.

Smart home heating is therefore a good way to save energy with smart and efficient heating technology.

How much does a smart home heating system cost?

Before we look at the cost of smart home heating, we need to look at the cost of a smart home system.

These vary greatly and range from a few hundred euros for entry-level packages to expensive wired systems of at least 5,000 euros.

In order to be able to heat smartly in your own Smart Home, you need five to six smart thermostats on the radiators. These cost around 150 euros to purchase.

Why is it worth investing in smart thermostats?

Both smart room and radiator thermostats can be easily connected to common heating systems and controlled intuitively.

They adapt to individual preferences and heat only as needed. Smart thermostats are therefore an ideal combination of cost savings and comfort.

Particularly in German households, where heating accounts for around 75 percent of the total energy demand, smart thermostats offer efficient ways to reduce energy costs and protect the environment.

What Types of Smart Home Heaters are there and which one is right for you?

When looking for the right smart radiator thermostats for your home, there are three different types to choose from.

  • Manual radiator thermostat
  • Electronic radiator thermostat
  • Radio radiator thermostat

What distinguishes a manual radiator thermostat and what are the advantages and disadvantages?

This classic variant is particularly suitable for those on a budget.

If the thermostat works mechanically, it is usually equipped with five levels, each of which provides a different room temperature. With classic radiator thermostats, you have to set these individual levels manually.

However, you should note that the actual room temperature can deviate from the temperature indicated in the respective set level.

This is due to the long-term wear of the thermostats. In addition, a build-up of heat can occur, which will cause the thermostat valve to close.

Advantages
  • Relatively low purchase price
  • Easy handling
Disadvantages
  • Inaccurate temperature setting

What are the characteristics of an electronic radiator thermostat and what are its advantages and disadvantages?

Electronic radiator thermostats (programmable radiator thermostats) are usually battery operated and usually have a digital display that you can use to set the temperature.

Here you can also enter different heating cycles and thus heat more predictably.

By heating in advance, you can save on heating costs, but this only works optimally if you know your daily routines very well and if you have hydraulically balanced heating systems.

Of course, it is not only possible to heat during the set times. Instead, you also have the option of operating the thermostat manually.

In principle, you can benefit from a convenient temperature setting if the radiator thermostat is programmable.

Advantages
  • Convenient and precise temperature setting
  • heating intervals adjustable
  • heating cost savings possible
Disadvantages
  • Batteries required
  • can only be used optimally when daily routines are as constant as possible

What are the features of a radio radiator thermostat and what are the advantages and disadvantages?

Radio radiator thermostats can be connected wirelessly via radio, WLAN or Bluetooth.

The measurement of these thermostats is usually taken over by fine sensors. You can usually install these temperature sensors anywhere in the room.

In addition, the radiator thermostat radio models consist of a component that you attach directly to the heating. Most of the time, there is also a central device through which you can adjust the temperature. Some models are even equipped with a remote control.

There are also radiator thermostats on the market that allow you to adjust the heating temperature easily and conveniently via an app on your smartphone or tablet PC.

In models with radio, WiFi or Bluetooth, the heating intervals can also be individually programmed and integrated into the Smart Home System.

However, the numerous possibilities of the wireless radiator thermostats are also reflected in the price. Most models are quite expensive. In addition, the installation of these thermostats is also more complex.

Advantages
  • Simple operation
  • control usually possible via a central device or app
  • heating intervals adjustable
Disadvantages
  • Usually high purchase price
  • Complicated installation

Purchase Criteria: You can use these Factors to compare and evaluate Smart Home Heaters

In the following, we will show you which factors you can use to decide between the many possible smart heating thermostats:

Heating function

While cheaper models usually have to be programmed manually and do not offer much more than a manual heating timer, control via app or control module on the wall is already possible in the mid-price category.

The sophisticated smart thermostats can not only be set, but can also learn about user behaviour and further develop the heating plan in the background through their intelligent algorithms.

In addition, many smart systems in all price classes offer heating plans for holidays or for frost protection in winter.

Learning function

Settings that were initially made manually are further developed by technically high-quality heating thermostats through algorithms and dynamically adapted to the actual user behaviour.

In this way, functions such as "window open" detection are also made possible.

Radio standard

When setting up a Smart Home system, the frequency is particularly important, as it is used for communication between the individual components.

Some systems use the domestic WLAN network. This does not pose any problems as long as there is enough bandwidth.

However, it becomes problematic in rural regions where not every household has fast internet.

Here, special Smart Home wireless standards (e.g. ZigBee) can be a solution, as the domestic WLAN network is no longer additionally burdened.

Range

As with other Smart Home products, the maximum range is measured in the open field. It can therefore be severely limited by various sources of interference (walls, ceilings, furniture).

Presence detection

Thanks to presence detection, the heating knows when you leave the room and then automatically adjusts the temperature to the empty room. As soon as you come back into the vicinity of the Smart Home heating, the temperature is automatically adjusted again.

Facts worth knowing about Smart Home Heating

How do I install the Smart Home heating thermostat correctly?

First you have to replace the radiator thermostat. To do this, unscrew the old thermostat on your heating system. It is easier to remove the thermostat if you turn the old radiator to the maximum beforehand.

Then carefully loosen the large screw with which the previous thermostat is fixed, preferably with a pipe wrench.

Now you can remove the old thermostat. Then you can mount the Smart Home-compatible thermostat. To do this, place the Smart Home thermostat on the connection of your heating system and fasten it with the appropriate screw.

Now the thermostat can be connected wirelessly to the Homebase. To do this, start the SmartHome app and log in. Then connect the device via +.

Alternatively, you can search for the device and integrate it via the device selection
