What is UL1118?

UL1118 is a widely recognized technical standard in the industry. It sets out criteria and requirements for electrical heating appliances, such as electric baseboard heaters, radiant heaters, and convector heaters. These criteria cover safety, performance, and energy efficiency, ensuring that consumers are protected and that products meet specific quality standards.

Safety Requirements

The safety requirements outlined in UL1118 are designed to prevent hazards such as electric shock, fire, and overheating in electrical heating appliances. This includes rigorous testing procedures to evaluate the impact of fluctuations in power supply, insulation resistance, temperature control, and protective measures against short circuits and other potential risks.

Performance Standards

In addition to safety, UL1118 also specifies performance standards for electrical heating appliances. This includes evaluating factors such as heat output, temperature control accuracy, uniform heat distribution, and energy efficiency. By adhering to these standards, manufacturers can provide reliable and efficient heating solutions to consumers.

Energy Efficiency Rating

UL1118 introduced an energy efficiency rating system to help consumers choose appliances that save both energy and money. Appliances are tested for their ability to convert energy into heat effectively, minimizing energy waste. The rating scale from A++ to D allows consumers to compare products based on their energy consumption and choose appliances that align with their eco-friendly goals.
