Most homes feel comfortable and safe with the heat set somewhere around the upper 60s to low 70s Fahrenheit (about 20–22 °C) when people are awake and at home.

Good default settings

  • For general comfort when you’re home and awake, a thermostat setting around 68–72 °F (20–22 °C) works well for most people.
  • Many energy-efficiency guides suggest aiming near 68–70 °F in colder weather to balance comfort and heating costs.

At night or away

  • For sleep, many experts recommend a cooler bedroom, often around 60–67 °F (about 16–19 °C), as long as you have adequate bedding and clothing.
  • When you’re away from home in winter, turning the heat down a bit (for example into the low–mid 60s °F) can save energy while keeping the home safe from issues like frozen pipes, depending on your climate and insulation.

Health and safety notes

  • Health guidance generally considers indoor temperatures of roughly 64–75 °F (18–24 °C) safe for healthy adults with normal clothing.
  • Vulnerable people like infants, older adults, or those with heart or breathing problems may need slightly warmer rooms, often at least about 68 °F (20 °C).

How to fine‑tune it

  • Start around 68–70 °F and adjust 1–2 degrees at a time until everyone at home feels reasonably comfortable.
  • Consider factors like drafty windows, upstairs vs. downstairs rooms, your bedding, and what you’re wearing indoors, since these can matter as much as the exact number on the thermostat.

If you tell more about where you live (climate), who’s in the home (kids, elderly, etc.), and whether your bill is a big concern, a more tailored range can be suggested.
