The importance of heat alarms in your home

Fire Safety

20 January 2025

Did you know that over 50% of domestic fires in the UK start in the kitchen?

Kitchens, garages, and other high-risk areas are where traditional smoke alarms might not perform optimally due to false alarms from fumes or humidity. This is where heat alarms step in to provide reliable protection. Unlike smoke alarms, heat alarms are designed to detect rapid temperature increases, ensuring safety without the hassle of nuisance triggers.

Let’s explore why heat alarms are a vital addition to your home’s fire safety measures.

Why Install Heat Alarms?

1. Designed for rooms with fumes or dust

Heat alarms are ideal for kitchens, garages, utility rooms, and lofts—areas where dust, fumes, or steam can cause standard smoke alarms to malfunction.

2. False alarm prevention

These alarms detect sudden temperature rises rather than smoke, avoiding false alarms caused by everyday cooking or humidity.

3. Fast detection saves lives

Advanced technology, like FireAngel’s Thermistek or Thermistor systems, detects fires early, giving you critical extra time to act.

4. Complementary to smoke alarms

For full home protection, combine heat alarms in high-risk rooms with smoke alarms in living areas, bedrooms, and hallways. Interlinked alarms ensure that if one sounds, they all do.

Where and how to install heat alarms

  • Best Locations: Kitchens (near cookers), garages, utility rooms, and lofts.
  • Placement Guidelines: Install alarms on the ceiling, ideally in the center of the room, at least 300mm away from walls or light fittings. Avoid wall mounting.
  • Professional Installation: Mains-powered models must be installed by a qualified electrician.

Maintenance for long-term safety

  • Weekly Testing: Press the test button to ensure the alarm is functioning.
  • Quarterly Cleaning: Use a vacuum or soft cloth to remove dust and debris. Avoid solvents or cleaners.
  • Replace When Needed: Check the alarm’s replace-by date to ensure sensors remain effective.
