It’s hard to guess which is the best temperature to heat your home, while being budget friendly. Does turning up the thermostat at a high temperature for a shorter amount of time work? Or should you go for a lower temperature for longer?
There also isn’t one correct answer. On the one hand, some professionals argue you should keep your heating on low throughout the day.* On the other, you should only turn your heating on when necessary.
What’s the best temperature for my central heating?
According to the Energy Saving Trust**, the best temperature for central heating in the UK is between 18°C and 21°C during the winter, (with a small 18°C boost in the early, colder days of spring and autumn if you feel you need it).
Much higher than this won’t be efficient. It’s a common misconception that the higher you set your thermostat, the quicker your home will heat. This isn’t true - it’ll just be warmer and will burn more energy to fill your home and heat your water.
What key factors can influence the temperature of a room?
There are numerous factors that can influence a room temperature from the size of the room to how many people contribute to the ambient temperature. Below are a few other factors that can influence the overall temperature of your home.
- Air temperature is a measure of the hotness or coldness of the air, which is influenced by how hot or cold it is outside of the home.
- Radiant temperature is heat that is expelled from items within the room like an oven.
- Air velocity is essentially air moving through the room caused by factors such as open windows and draughts. This can also be improved by adding curtains, shutters or draught-proofing.
- Humidity is the moisture within the air, the more humidity in the air the easier it is to maintain a warmer temperature. If the moisture level is low, the temperature inside your home should be warmer.
What's the ideal room temperature? ***
Taking into consideration the above factors each room within your home will still have an ideal room temperature for optimal comfort. Purchasing smart heating controls, like thermostatic radiator valves (TRVs) and smart thermostats will allow you to adjust the temperature in each room, so each room is set to its optimal temperature, providing you with more energy efficient heating.
Adjusting each room’s temperature individually and turning off areas in the home that are not being used, will not only save you money but ensure each area is suited to the room and the user's needs. Find out more about central heating controls here.
