UL Listed Space Heater

What is UL Listing, and Why is it Important?

UL listing is a system of testing and approving consumer products for general safety. The letters ‘UL’ stand for Underwriters Laboratories. Underwriters Laboratories is a not-for-profit organization whose sole mission is to test and approve chemical, mechanical, and electrical products. The organization uses nationally-recognized standards to determine the level of risks of fire and other hazards. Products that carry the small logo have been tested and found to be safe for use by consumers.

Underwriters Laboratories started back in 1894 as Underwriters Electrical Bureau in Chicago. Currently, the organization operates in more than 70 countries and tests more than 18,000 different consumer product categories.

UL listing is essential because of several reasons. First, the UL is a not-for-profit organization. As such, it does not have any commercial interest in the companies that make the tested products. Any product that carries the UL logo has been subjected to independent tests and safe for use.

Second, UL uses a comprehensive and rigorous program to ensure that companies maintain safety standards in all the products they manufacture and market. The organization conducts random visits to companies to check the production process and test other products. This approach helps prevent companies from ending up producing substandard products later after getting a few of their products approved by UL.

Is UL Listed the Same as UL Approved?

When a product has the UL listing mark, it means that the product has been subjected to comprehensive tests and safe for use. The UL listing mark on products is an assurance that the product is unlikely to cause fires and related accidents when in use.

The UL recommended mark is used for products that are supposed to be used as components. If you buy an item that is UL approved, it means that you can use it as part of a system with the assurance that the component will not cause fires or related accidents.

For products to get the UL listing or UL approved mark, they are usually tested against national and international standards. Therefore, the UL listing or UL recommended mark is more stringent than the UL approved one.

Safety Features to Look for When Choosing a Space Heater

Heating equipment, including space heaters, pose a significant level of danger in homes. If a heating device is poorly handled, it can cause home fires or burns. It would help if you were careful when purchasing and using heating equipment.

Heating equipment comes with different safety features. Here are a few things that you should look out for when purchasing a UL listed space heater for home use.

Overheat Protection

Although modern space heaters have programmable timers and inbuilt thermostats, you need additional features to protect you against overheating. A heater can easily overheat and cause considerable damages in the home. Luckily, many space heaters have a safety fuse that prevents overheating. When the heater’s temperature rises rapidly to risky levels, the overheat protective fuse breaks, thus cutting the power supply. Always go for space heaters that have this safety feature.

Ceramic Heating Element

A ceramic heating element is safer than traditional ones that usually glow red ad are enclosed in metal casings. The safest space heaters have ceramic heating elements combined with a fan. The combination of a ceramic heating element and a fan ensures effective and even distribution of heat in large indoor spaces. Additionally, the ceramic heating element is less likely to cause fire accidents and burns than traditional ones.

Tip-Over Protection

Space heaters can easily cause fires if they fall, and their heating element gets into contact with any combustible material near it. Heaters can fall if people or even pets accidentally knock them. The tip-over protection feature prevents this type of accident from occurring. A heater that has this feature automatically switches off it falls. This simple maneuver ensures that you are safe even if your heater falls accidentally.

Cool-To-Touch Exterior Body

Choose heaters that are designed to be cool even when they work for a long time. For heaters that have the cool-to-touch feature, the surface temperature remains within safe levels. If a heater’s casing is not designed to remain cool, then touching it can cause burns. Because space heaters are mostly placed on the floor, you should be mindful of kids and pets. It is better to choose a heater that has a cool-to-touch housing than one whose casing heats up.

Space Heater Safety Tips

In addition to choosing space heaters with advanced safety features, follow the following tips to ensure these devices’ safe use in your home.

  • Follow the manufacturer’s instructions. All space heaters come with detailed instructions on how you can use them safely. Read and understand all the instructions, warnings, and guidelines provided by the manufacturers.
  • Switch off the space heater when you leave the room. Although space heaters have inbuilt safety features, it is not safe to leave them unattended. Anything can go wrong when no one is watching. Switch off your space heater even if you are leaving the room for a few hours only.
  • Use your space heater for supplemental heating only. Do not try to use the heater for any other purpose apart from providing supplemental heating.
  • Install smoke detectors. Smoke detectors trigger an alarm to sound in case there is smoke in the house. These devices can help you react quickly if your heater gets into contact with combustible material in the house.
  • Plug your space heater directly to the wall socket. Heaters have specific wattage and amperage values that they need to operate properly. Heaters can blow extension cords because the cords do not supply the required wattage and amperage values. Unless you have the right extension cord, ensure that you plug the heater directly to the wall socket.
