How to Turn on the Wall Heater?

Wall heaters are a popular heating solution for small spaces, offering an efficient way to warm a room during colder months. Turning on a wall heater may vary slightly depending on its type—electric, gas, or propane. Follow this step-by-step guide to safely turn on your wall heater.

Step-by-Step Process:


1. Check the Type of Wall Heater

  • Electric Wall Heater: An electric wall heater uses electricity to generate heat through heating elements.
  • Gas Wall Heater: Powered by natural gas or propane and may require lighting a pilot light.
  • Hydronic or Oil-Filled: Circulates warm fluid for radiant heat.

Knowing the type of heater helps determine the specific steps needed to turn it on.

2. Inspect the Heater

  • Ensure the heater is clean and free of dust or debris.
  • Check the area around the heater to ensure it is clear of flammable materials like curtains, furniture, or paper.
  • Confirm the power or gas supply to the heater is connected and functional.

3. Locate the Heater Controls

  • On/Off Switch: Typically found on the unit’s front, side, or bottom.
  • Thermostat Dial: Used to adjust the temperature.
  • Ignition Button or Knob: Found on gas heaters for lighting the pilot light.

4. Turn On an Electric Wall Heater

  1. Flip the Power Switch to the On position.
  2. Set the Thermostat Dial to the desired temperature.
  3. Allow a few minutes for the heater to warm up and radiate heat.
Flip the power switch on the wall heater to the on position

5. Turn On a Gas Wall Heater

  1. Check for Gas Supply: Ensure the gas valve near the heater is turned to the On position.
  2. Locate the Pilot Light:
    • Open the access panel or locate the pilot light area.
    • Identify the ignition button or control knob.
  3. Light the Pilot Light:
    • Turn the control knob to the Pilot setting.
    • Press and hold the knob while pressing the ignition button (if available) to ignite the pilot light.
    • If there is no ignition button, use a long lighter or match to ignite the pilot.
    • Continue holding the control knob for 30 seconds to ensure the pilot light stays lit.
  4. Set to Heat Mode: Once the pilot light is lit, turn the control knob to the On position and adjust the thermostat to the desired temperature.
adjust the control knob for the pilot light to the "On" position

6. Monitor the Operation

  • Check that the heater is functioning properly by feeling for warm air or heat emanating from the unit.
  • Ensure no unusual noises or smells that could indicate a problem.

Safety Tips

  • Electric Wall Heaters:
    • Do not cover the heater or block airflow with furniture or other items.
    • Use only properly rated electrical outlets and ensure the electric wall heater is on its circuit to prevent overloading.
  • Gas Wall Heaters:
    • Check for gas leaks before turning on the heater. If you smell gas, do not attempt to light the heater. Turn off the gas supply and call a professional immediately.
    • Ensure proper ventilation to prevent carbon monoxide buildup.

Common Issues and Troubleshooting

  • No Heat from Electric Heater:
    • Check if the circuit breaker has tripped.
    • Inspect the thermostat or power switch for issues.
  • Pilot Light Won’t Stay Lit:
    • Clean the pilot assembly and check for obstructions.
    • Ensure adequate gas pressure to the unit.
  • Burning Smell:
    • A slight smell may occur when turning on a heater after a long period of disuse. If the smell persists, clean the unit to remove dust.

When to Call a Professional

  • The pilot light won’t ignite or stay lit after multiple attempts.
  • The heater does not produce heat despite being turned on.
  • You detect a gas smell or suspect a leak.
  • There are unusual noises, vibrations, or electrical issues.

By following this guide, you can safely and effectively turn on your wall heater, ensuring a warm and comfortable environment.
