What temperature should I set the heating to in winter?
In this article, we'll explain the ideal temperature range to set your heating at, both day and night, during winter to ensure comfort while minimising energy waste.
As winter approaches and temperatures fall in our homes, a common dilemma arises: What temperature should we set the heating to in order to stay comfortable without letting energy bills soar? Striking the perfect balance between comfort and energy efficiency may seem challenging, but it's essential for maintaining a warm and welcoming home during the colder months. Choosing the right temperature affects not only our physical comfort but also our finances. This article explores best practices for adjusting heating during winter, taking into account general recommendations as well as individual needs, to ensure a comfortable and energy-efficient cold season.

The science of thermal comfort
Thermal comfort is a concept that goes beyond simply feeling hot or cold. It describes the physical comfort a person experiences in an environment where there is no need to put on extra layers or seek additional warmth. This ideal state is achieved by balancing several factors that influence how we perceive temperature.
To measure thermal comfort, experts use the Thermal Comfort Index, which takes into account factors such as air temperature, wind speed, humidity, and thermal radiation. Each of these elements plays an important role in our perception of heat and cold.
Humidity, for instance, can intensify our sensation of heat or cold. In winter, a humid environment can make the air feel colder than it actually is, as moisture draws heat away from the body more quickly. Conversely, a very dry environment can cause dehydration and influence our sense of comfort.
Physical activity is another important factor. The more active a person is, the more body heat they produce, which may require adjusting the heating. A property where people engage in intense physical activities may need a cooler room temperature than one where most activities are sedentary.
General recommendations
Finding the ideal temperature for your home during winter can be the difference between a cosy atmosphere and a hefty energy bill. The World Health Organization (WHO) suggests an indoor temperature of 18°C as suitable for general overall health. During the day, it is recommended to set the heating to between 20 and 22 degrees Celsius to ensure comfort without wasting energy. This temperature range is considered optimal for most daytime activities, allowing a good balance between warmth and efficiency.
At night, needs change slightly. Lowering the temperature to between 16 and 18 degrees Celsius is recommended, as sleeping in a cooler environment can improve sleep quality and decrease energy consumption. Children's rooms, however, should be kept around 17-20 °C. This temperature is ideal for sleeping as it helps regulate body temperature and encourages deeper rest. Using appropriate blankets can also help compensate for the temperature drop and maintain a comfortable environment.
It is also important to adjust temperatures in different rooms according to their specific use. Living rooms and bedrooms used during the day benefit from warmer settings, while less frequently used areas can be kept cooler to conserve energy. These small modifications not only maintain a comfortable home but also promote efficient use of heating, reducing the impact on energy bills.
Impact on energy consumption
Correctly adjusting the heating temperature is essential not only for a comfortable home but also because it significantly affects energy consumption and, consequently, your monthly bills. Raising the thermostat by just one degree can increase energy consumption by up to 7%, making it a considerable expense during winter.
An effective way to optimise heating and cut costs is to install programmable thermostats. These devices allow you to set specific heating schedules that adapt to daily routines. For example, the temperature can decrease automatically during sleeping hours or when the property is empty, thereby ensuring efficient energy use.
Another key measure is to improve home insulation. Effective insulation in walls, ceilings, and windows reduces heat loss, so the heating system doesn’t have to work as hard to maintain a comfortable temperature. Small improvements, such as sealing draughts around doors and windows, can bring considerable savings.
Maximising sunlight during the day also helps heating by simply allowing the sun to warm rooms naturally. Adopting these practices will not only lower your energy bills but also reduce your environmental footprint, encouraging a more sustainable, responsible lifestyle.
Using air conditioning in winter
Is it good to leave the air conditioner on all night?
Leaving the air conditioner on all night has both pros and cons. On one hand, it ensures a consistently comfortable temperature during sleep, which can be beneficial in extremely cold climates. However, leaving it on continuously can greatly increase energy consumption and related costs. Additionally, some air conditioner models can dry the air, which may affect sleep quality. We recommend using the timer or programming function to switch the air conditioner off after a set period, thus balancing comfort with efficiency.
At what temperature does the air conditioner use less energy in winter?
The ideal temperature range for efficient use of the air conditioner in winter is 18 to 20 degrees Celsius. This range maintains a comfortable environment without overworking the appliance, helping to reduce energy consumption. Activating heat mode is also important, as some systems have specific settings designed to operate optimally in cold climates. Be sure to keep doors and windows closed to prevent heat loss and ensure the air conditioner operates efficiently.
In summary, managing heating efficiently is key to balancing comfort, energy efficiency, and cost savings. Correctly adjusting the temperature, using the air conditioner properly in winter, and making use of smart thermostat technology are all essential steps. These practices not only improve home comfort, but also contribute to a more sustainable lifestyle. We encourage you to adopt these strategies to enjoy a warm and efficient home.
