Do Electric Space Heater Produce Carbon Monoxide

How do I know if my heater is producing carbon monoxide?

According to the CDC, carbon monoxide is a silent killer that takes hundreds of lives per year. Unfortunately, you cannot tell just by looking at your furnace whether it is leaking carbon monoxide. You need a carbon monoxide detector or other special equipment to test the levels yourself.

Can electric heaters cause carbon monoxide poisoning?

Do Electric Space Heaters Produce Carbon Monoxide? No. Only heaters that burn a combustible fuel to create heat can cause carbon monoxide build-up in your home. An electrical heater works by having electricity flow through a metal heating or ceramic heating element to produce heat.
