In brief – Smoke Alarms will alarm when smoke is detected by the sensors within the unit whereas Heat Alarms will alarm when they detect a rapid rise in temperature in the atmosphere around the device. Heat Alarms have been specifically designed for areas with fumes and high humidity e.g. kitchens where cooking fumes are present and attics or garages where there is lots of dust and usually high humidity.
Over 50% of fires start in kitchens in domestic properties – installing a heat alarm in this room will mean you’re rapidly alerted to danger.
A Heat Alarm is perfect for detecting fires like those caused by faulty white goods, as they usually create a ‘blast’ of fire that’s very hot. Heat Alarms won’t false alarm to a dusty or humid room which makes it perfect for kitchens, utility rooms and garages where these items are usually found.
