Digital Thermostats Buying Guide

When you want to buy a digital thermostat, it is essential to consider several important issues. As you will see, there are various models with different performances: in this section, we will answer the most frequently asked questions about these devices.

What Exactly Are Digital Thermostats?

Digital thermostats are electronic control devices, designed to regulate the functioning of heating systems. Therefore they can control both the temperature itself and the switching on and off of the device. Also, they have a digital screen through which the user can view and adjust the temperature.

What Are the Advantages and Disadvantages of Digital Thermostats?

Digital thermostats are more precise than analogue devices: with them, it is possible to adjust the temperature straightforwardly. Furthermore, as they are equipped with a digital screen, you can know the exact temperature at all times.

Most of these devices allow you to program the switch-on and switch-off times. If they are equipped with a WiFi connection, you can connect them to your smartphone or tablet, and manage the heating system in comfort from practically any place.

Also, it allows you to save energy and take care of the environment. In the list below, you can discover all the other advantages of these devices.


They are much more precise than analogue thermostats. They allow you to adjust the temperature of your home and office at any time, automatically. Since they are equipped with a screen, it is possible to know the temperature at any time. Those that are equipped with WiFi can be connected to various devices, such as smartphones and tablets for greater convenience.

Since they allow you to check the temperature at all times, they can help you save energy and money on the end-of-month bill. Furthermore, lower energy consumption contributes to the fight against climate change; they are straightforward to use, and most models are compatible with various heating systems.


They imply a large investment at the beginning, which over time amortizes. A small installation is required.

Is It Worth Buying a Digital Thermostat?

Without a doubt, it is worth buying a digital thermostat. Even if your purchase involves a large initial investment, the money will have to be recovered with the bills, which will be much cheaper. Plus, they allow you to take advantage of the convenience of easily checking your home temperature.

In addition to this, the environmental advantages deriving from lower energy consumption must also be added. If you opt for an intelligent thermostat, you can control the temperature from your mobile device, even when you are not at home or in the office, and carry out zone programming.

Who Should Buy a Digital Thermostat?

The use of digital thermostats is recommended for both home and offices. These devices are suitable for all places where heating systems are widely used and where zone programming is particularly useful, especially if the rooms are huge.

How Does a Digital Thermostat Work?

Since there are various models of digital thermostats, the operation can vary from one to the other. However, in general, these devices rely on electrical sensors that control temperature changes: based on these changes and the temperatures that have been programmed, the thermostat turns the heating system on or off.

Where Is It Best to Place the Digital Thermostat?

First of all, it is better to place it away from sunlight, so that this does not affect the temperature reading and, therefore, the operation of the device.

Similarly, it is better to keep it away from appliances that can be a source of heat or that cool the environment. Lastly, it may be better to install it in a room where there is enough activity, and at the height of 1.50 m to 1.80 m.

Factors to Consider Before Purchasing

Compatible Heating Systems

This is the first criterion to watch out for. Always make sure that the thermostat is compatible with the heating system installed in your home. Fortunately, many models are widely compatible, both with gas boilers and with heat pumps and heated floors.


Since it is an element that will surely be visible in the home or office, you cannot ignore its design. In this sense, manufacturers strive to find increasingly elegant as well as functional designs. Thus, they can be adapted to the style of the room in which they will be installed.

Most of the thermostats are white. Also, there are wireless and other models that connect via cable. Another important aspect is the ease of installation: some thermostats are specially designed so that they can be connected to an electrical outlet.

User Interface and Ease of Use

All smart digital thermostats can be controlled by an application installed on the smartphone or tablet, or even by Smart Home devices. So, a key aspect to consider of these apps is the ease of their interface, especially if they are to be used by people who are not very practical with new technologies.


Digital thermostats have various additional functions, which go well beyond temperature control: the most common one allows you to program their on and off. Some are security functions to ensure that the system is turned off under certain conditions.

A new function allows you to use the zone heating system: some thermostats also offer a history of data on consumption, temperatures and on and off times. There are also smart features for returning from vacation or that adapt to our daily habits.


Digital thermostats with WiFi connection offer the possibility to connect them to smartphones and tablets. This way, you can control them remotely from anywhere with a simple internet connection. Furthermore, some thermostats can also be connected to Smart Home devices.
