What is the cheapest temperature to keep your house in winter?

As the winter season approaches, many homeowners find themselves grappling with the question of what temperature to set their thermostats at to strike a balance between comfort and cost. With energy prices on the rise, it’s crucial to find the sweet spot that keeps you warm without breaking the bank. In this article, we will explore the factors to consider when determining the cheapest temperature to keep your house in winter, backed by research, examples, and statistics.

The Impact of Temperature on Energy Consumption

Before delving into the ideal temperature, it’s important to understand how temperature affects energy consumption. Heating your home accounts for a significant portion of your energy bill during the winter months. The lower the temperature you set, the less energy your heating system will consume. However, setting the temperature too low can lead to discomfort and potential health risks.

According to the U.S. Department of Energy, for every degree you lower your thermostat during the winter, you can save about 1% on your heating bill. This means that finding the right balance is crucial to achieve both cost savings and comfort.

Considerations for Setting the Temperature

When determining the cheapest temperature to keep your house in winter, several factors come into play:

  • Climate: The climate in your region plays a significant role in determining the ideal temperature. Colder climates may require higher indoor temperatures for comfort.
  • Insulation: The quality of insulation in your home affects how well it retains heat. Well-insulated homes can maintain warmth at lower temperatures.
  • Personal Comfort: Each individual has their own comfort level. Some people may prefer a warmer environment, while others are comfortable with cooler temperatures.
  • Health Considerations: Certain health conditions, such as respiratory issues or arthritis, may require a warmer indoor temperature for comfort and well-being.

Based on research and expert recommendations, the ideal temperature range for most households during winter is between 68°F (20°C) and 72°F (22°C) when people are at home and awake. This range provides a balance between comfort and energy efficiency.

However, when you’re away from home or asleep, it is advisable to lower the temperature by a few degrees to save on energy costs. The U.S. Department of Energy suggests setting the thermostat to around 62°F (17°C) during these periods. This adjustment can result in significant savings without sacrificing comfort.

Case Studies and Statistics

Several case studies and statistics support the recommended temperature range:

  • A study conducted by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) found that a temperature range of 68°F to 72°F is comfortable for most people.
  • The U.S. Environmental Protection Agency (EPA) states that homeowners can save up to 10% per year on heating and cooling costs by simply adjusting their thermostat by 7-10°F for eight hours a day.
  • A survey conducted by the Energy Saving Trust in the UK revealed that lowering the thermostat by just 1°C can result in an average annual savings of £80 ($110) on energy bills.


When it comes to determining the cheapest temperature to keep your house in winter, it’s essential to strike a balance between comfort and cost savings. By setting your thermostat within the recommended range of 68°F to 72°F when you’re at home and awake, and lowering it to around 62°F when you’re away or asleep, you can achieve significant energy savings without compromising your well-being.

Remember to consider factors such as climate, insulation, personal comfort, and health considerations when making adjustments to your thermostat. By implementing these strategies, you can keep your home cozy during the winter months while keeping your energy bills in check.
