We all love a warm, cozy house on a chilly day. Space heaters are a reliable source of warmth that’ll keep you and your living space warm.
But, not all heaters are safe for extended periods of heating. So, if you want to snug in the warmth when sleeping, you must find a safe heater to leave overnight.
Heaters suitable for overnight use have safety features to prevent overheating and accidental fires. This article will guide you on what to look for when buying a space heater for overnight use and the safest space heaters to consider.
What Makes Heaters Safe for Overnight Heating?
According to the Consumer Product Safety Commission, electric space heaters are involved in around 50 deaths yearly. The National Fire Protection Association estimates that space heaters cause 32% of home fires. They cause about 80% of the deaths associated with home heating.
Here are things to consider when buying a space heater for overnight use.
Type of Heaters
- Electric Heaters: These heaters use an electric heating element to generate heat. They come in different types, including radiant, fan-forced, and convection. Old electric heaters are unsafe for overnight use because the heating element can overheat. But modern models come with overheat protection, adjustable thermostats, and tip-over switches.
- Ceramic Heaters: Ceramic heaters use ceramic heating elements that heat up quickly. They distribute heat evenly, have built-in safety features, and are often compact and portable. Ceramic heaters are safe to leave on overnight.
- Oil-filled Radiator Heaters: These heaters contain diathermic oil, which is heated and circulated through the fins. They produce consistent heat, even after they’re turned off. They often come with overheat protection and have a cool exterior, making them suitable for overnight heating.
- Infrared Heaters: Rather than heating the air, infrared heaters use infrared radiation to heat objects and people directly. They produce instant heat, are energy efficient, and have built-in safety features suitable for overnight heating.
Tip-Over Protection
The safest space heaters have tip-over protection that automatically turns it off if accidentally knocked over. This minimizes the risk of the heater causing accidental fires and other hazards when it’s not upright.
Overheat Protection
Look for a heater with an overheating protection feature. The heater detects when the temperature reaches unsafe levels and automatically shuts off. It’s a crucial feature, especially when the heater operates overnight.
Safety Certification
The heater you’re considering should be certified to show that it has been tested and meets the safety standards. Check for certification marks like UL, CSA, and ETL.
Thermostat Control
Heaters with thermostat control let you set your desired temperature. Once the ideal temperature is reached, the heater will cycle on and off to keep it at that level. This prevents excessive heat buildup and maintains a consistent temperature.
Cool-to-Touch Housing
A cool-touch exterior is necessary, especially if you have pets or small children. Even when the heater is running, the outer surface is still cool to the touch. This minimizes the risk of accidental burns.
