Why does my heat alarm keep going off?

General

23 April 2026

Heat alarms trigger at temperatures between 54 and 65 degrees Celsius. If your heat alarm triggers frequently, check that it is not positioned directly above a hob, oven or toaster where concentrated heat rises. Reposition the alarm further from the heat source while keeping it on the ceiling. If the alarm continues to trigger without an obvious heat source, it may be faulty and should be replaced.
