On cold days, you're certainly glad to come home to a warm flat and no longer have to freeze. But what is the ideal room temperature? On average, the temperature in your home should be around 20 degrees. Some rooms can manage with less heat, while others can be a few degrees warmer.
By the way: Room temperature and room temperature are not the same thing. Room temperature is the temperature that is measured with a thermometer in the room. The room temperature is the temperature that you subjectively perceive in the room.
So what are the optimum temperatures in the individual rooms?
You certainly don't want to be shivering after a bath or shower. That's why the temperature in the bathroom can be slightly higher than in the rest of the home. The guideline is 22 to 23 degrees Celsius in the bathroom. It is important that you ventilate the room sufficiently after showering so that moisture can escape. This will prevent mold from forming.
For a good night's sleep, the temperature in the bedroom should be between 18 and 20 degrees Celsius, but never higher. Many people also find 16 or 17 degrees at night comfortable. It is important that you neither sweat nor freeze while sleeping. During the day, you should keep the bedroom door closed to keep the cool air in the room. Before going to bed, it is advisable to air the room briefly.
You usually spend most of the day in the living room. As you don't move around much on the sofa or while watching TV, the living room can be slightly warmer than the rest of the home. 20 to 23 degrees Celsius is considered ideal and is perceived as pleasant by most people.

The oven, hob and fridge in the kitchen give off heat, so that the heating doesn't have to work as hard there as in other rooms. You can therefore set the temperature in the kitchen lower than elsewhere. The optimum room temperature for the kitchen is between 17 and 20 degrees Celsius.
It is not so easy to determine the exact temperature of a room. This is because the temperature can vary depending on where you are in a room. It is best to measure the temperature with an analogue or digital thermometer in the middle of the room, about one metre from the floor. The thermometer should not be near the heating or in a very sunny spot in the room, as this can falsify the result.
Wouldn't it be practical if you didn't have to constantly turn the heating up and down, but the room temperature remained constant and ideal? Shelly products make this very easy.
As you probably know, you should ventilate several times a day - in other words, open the windows fully for a few minutes. To avoid wasting energy during this time, you should always turn down the heating during ventilation.
The Shelly BLU TRV radiator valve, which is installed on a radiator and makes heating control smart, helps you to do this. It’s really easy: simply unscrew the old radiator valve, screw on the BLU TRV, pair it with the BLU Gateway Gen3 or another third-generation Shelly device, and connect it to the app.
If you combine the valve with the BLU Door/Window Mini ZB door and window contact, you can create commands - for example, to automatically switch off the heating when you open the windows for ventilation. These commands or scenarios in the app also work with electric heating or underfloor heating.
You can also maintain the room temperature with an electric heater. You can do this by connecting it to the Shelly Plug M Gen3 smart socket. This is also done quickly: plug the plug of the electric heater into the Plug M, plug the Shelly device into the socket and then connect it to the Shelly app.
You can also make underfloor heating smart and control it as required. There are various options depending on the design of your underfloor heating system: If your underfloor heating has a valve, you can use the Shelly BLU TRV. You can connect a relay such as the smart switch Shelly 1 Gen4 or the smaller version Shelly 1 Mini Gen4 to the manual controller of the underfloor heating. We explain how this works here.
Very practical: Using the Shelly Smart Control app, you can set up schedules for the respective heating appliances or rooms to maintain an ideal room temperature at all times. With the help of such a schedule, you can specify, for example, that your living room should be at a cosy temperature at 6 p.m. when you get home from work. Or that your bathroom is pleasantly warm for your morning shower.
With rising energy costs, it's worth lowering the room temperature a little. Every degree lower can save you up to six per cent of heating energy. This is not only easy on your wallet but is also good for the climate because your oil or gas heating emits less CO2. Smart home devices from Shelly help you save:
An optimum temperature in all rooms is a key factor in ensuring that you enjoy spending time at home and feel comfortable. But there are other reasons why you should aim for an ideal room temperature.
Your immune system reacts sensitively if it is too hot or too cold in your home. If you turn the heating up too high, this leads to dry heat with low humidity. This dries out the mucous membranes and viruses and bacteria can colonise, possibly making you ill. An ideal room temperature also increases concentration and performance.
The environment will also thank you if you optimize your room temperature. Fossil energy sources such as coal, oil and natural gas release millions of tones of CO2 into the atmosphere every year, causing air pollution and global warming. The less you heat, the fewer emissions are released into the environment. So with the ideal room temperature, you become a small climate saver.
Heating oil and gas are becoming more and more expensive. A good reason to lower the temperature in your home slightly. With a cosy jumper and socks, it's easy to keep warm even when the temperature is one or two degrees lower. However, you should not overdo the savings, otherwise there is a risk of mould because the walls will cool down.
Mould develops when the humidity in rooms is too high and the temperature is too low. Condensation then forms on cool surfaces, which can quickly lead to mould. Warm air, on the other hand, retains moisture. You should therefore not allow unused rooms to cool down too much and - just like all rooms in the home - ventilate them regularly.

The optimum room temperature depends on how the room is used and differs from room to room. In principle, it should be between 17 and 22 degrees.
The best temperature for sleeping is between 16 and 19 degrees. Ultimately, however, the optimum number of degrees in the bedroom depends on personal preference.
Radiators should be switched off during ventilation. This can be done very conveniently with the Shelly BLU Door/Window sensor, which recognises when a window is opened and then automatically turns down the heating.
The thermostat of a heating system reacts to the existing room air temperature and allows more or less heating water to flow into the radiator depending on the temperature setting. With the Shelly BLU TRV smart thermostatic valve, you can control the settings automatically via sensors or schedules.
With smart home devices, you can, for example, control the temperature in different rooms individually, lower the room temperature when you are away or reduce the heating when ventilating. A lot of heating energy can be saved with intelligent control.
