Best Temperature for Heater in Winter in Brisbane

The ideal constant temperature for your heater

Rather than cycling your heater on and off at high temperatures, “it’s better to find the ideal constant temperature and keep it running” for efficiency. It’s recommended to set temperatures around 20 degrees Celsius in winter, or as low as 18 degrees for home use.

Every degree you add to your heating system may lead to a 10% energy increase, while reducing temperature by 7-10 degrees for eight hours daily could decrease electric bills by up to 50%.

  • Adding winter rugs
  • Managing curtains and blinds to maximize solar warmth

What You Should and Shouldn’t do During the Winter

Do:

  • Schedule regular professional maintenance
  • Set consistent on/off times for efficient operation

Don’t:

  • Instantly raise temperature to maximum settings
  • Frequently turn heating on and off (allow full 3-hour cycles minimum)

Should I Consider a Reverse Cycle Air Conditioner?

Reverse-cycle systems are the best choice for Australian homes, offering both heating and cooling capabilities with 20-year potential lifespans when properly maintained.
