Why You Should Never Sleep with the Heating On

Date Published: 18/11/2024

Due to poor EPC (Energy Performance Certificate) ratings affecting about 8 million UK homeowners, vulnerable individuals may resort to leaving their heating on overnight to beat the chill. However, as our heating experts have discovered, leaving your system running overnight may result in some serious adverse results. 

Continue reading to learn why experts recommend never leaving your heating on at night and how British homeowners can stay warm at night.

8 Million Households Struggling

Even during the warmer months, homeowners with a lower EPC rating may rely on their heating systems to stay warm. The staggering number of British homes rated below band C for energy performance is an overwhelming statistic that underscores the nationwide issues of inefficient heating and inadequate insulation. 

Despite the warmer temperatures, these homes struggle to retain heat due to inefficient insulation and outdated heating systems. Due to this, occupants may resort to using their heating to achieve a comfortable and temperate environment, even during milder weather.

Health Issues

Leaving the heating on during the night may seem like a comfortable and cosy solution, however, it can cause a number of financial and health-related problems. Apart from the evident increase in energy consumption and bills, leaving the heating on can cause dry air. 

This is because prolonged use of your heating system removes moisture from the air, often resulting in a stuffy room, which can make it harder to breathe. Often, this can lead to dry coughs and sore throats which can disrupt your sleep.

Not only this but excessive heating can also strip the skin of its natural oils, causing dryness and irritation.

Mould

Another undesirable effect of leaving your heating on overnight is that it can contribute to moisture buildup which can manifest into mould growth. This not only poses serious health risks but can also lead to structural damage in your home.

Fleas and Bedbugs

Unpleasant pests like fleas and bedbugs thrive in warmer environments and running your heating system overnight can cultivate a favourable habitat for these nasty neighbours. If you need to sleep with the heating on, consider using natural deterrents such as peppermint oil to maintain a bug-free sleeping space.

Insulation Tips

Overall, feeling the need to use the heating in warmer weather highlights the importance of addressing underlying issues such as poor insulation and outdated heating systems. Investing in home improvements such as insulation upgrades, double or triple-glazing, and draught-proofing your home will reduce the need for continuous heating. 

Ultimately, this will lead to improved energy efficiency, reduced year-round reliance on your heating, cost-savings, and improved comfort for homeowners, regardless of the time of year.

Expert Advice

We advise shutting the heating off about half an hour before you head to bed as this allows your home to gradually cool, making for comfortable sleep. If leaving the heating on is still a necessity at night, we recommend lowering the temperature to 17-19ºC to prevent the issues outlined above.

For those relying on heating oil systems, it is crucial to keep an eye on your oil levels, especially if you need to use your system throughout the night. Consider installing one of our remote tank monitors to easily track your oil supply. This way, you can ensure you always have enough domestic heating oil to keep your home comfortable, particularly during the colder weather.
