Coming home to a cozy, warm house during winter is comforting. Provided that you find a heater, you can always leave it on.

An unsafe heater can cause fire hazards, dry skin, irritation, and allergies. Another significant concern is heaters that aren’t energy efficient, resulting in high heating bills. 

Fortunately, modern heaters are energy-efficient and have safety features to prevent accidents. Ensure the heater you’re considering comes with these features and meets standard safety requirements.

Things to Consider When Buying a Space Heater

If you need a heater that runs throughout, look for these features.

  • Energy Efficiency: Prioritizing energy efficiency minimizes your power bills. Look for a heater with features that optimize energy consumption, such as precise temperature control and a programmable thermostat. Check if it offers a low heat mode with a lower wattage and an energy-saving mode (ECO) for reduced consumption.
  • Tip-Over Protection: The longer the heater is on, the more the risk of tipping over. Tip-over protection automatically shuts off the heater if it’s accidentally knocked over, minimizing the fire risk.
  • Overheat Protection: This feature prevents temperatures from reaching dangerous levels, which can cause fire and damage. 
  • Cool Exterior: A heater whose exterior remains cool-to-touch when on means there’s less risk of accidental burns. This feature is vital for safety if you live with pets and children.
  • Thermostat Control: Opt for a heater with a precise and programmable thermostat to maintain a consistent and comfortable temperature. Heat regulation prevents unnecessary energy use and balances between warmth and efficiency.
  • Safety Certification: Look for heaters with recognized certifications, such as ETL, UL, and CSA. Such heaters undergo thorough testing and meet safety standards for use over extended periods.

All the heaters in this list have met these conditions and can be left on continuously. Your choice depends on your budget, the size of the space you want to heat, and your preference.
