Heating Products

Heating certification from the world’s safety science leader 

The heating industry is evolving with a push towards smart and sustainable technology. These changes create complex challenges for equipment manufacturers who need to balance the competing priorities of bringing heating products to market that are high-performing and energy efficient, without sacrificing safety, security or sustainability. 

As environmentally friendly and connected technology advancements continue to reshape heating regulations, our commitment to evolving with the industry never wavers. Our experts actively participate in industry associations that set standards for quality, safety and performance, including the International Electrotechnical Commission (IEC), American Boiler Manufacturers Association (ABMA), National Fire Prevention Association (NFPA), Saudi Standards (SASO) and many others worldwide. With a deep understanding of the heating industry, our technical experts help you simplify certification and comply with relevant regulations and standards while meeting demanding go-to-market deadlines. 

Work with us for the highest level of service in heating equipment safety testing, energy efficiency certification, product performance verification and cybersecurity certification.

Low GWP services

Refrigerants with low global warming potential (GWP) may be more environmentally friendly, but they’re also considered mildly flammable. Consequently, regional regulations increasingly require HVAC appliance manufacturers to reduce their products’ greenhouse emissions. Flammable refrigerant testing is becoming a central part of the HVAC/R equipment benchmarking, testing, assessment and certification process.

Key standards and regulations for HVAC/R products using low GWP refrigerants:

• UL/IEC 60335-2-40
  UL 60335-2-40 describes the requirements for electrical heat pumps, air conditioners and dehumidifiers, and is an ANSI/SCC-accredited U.S./Canada binational consensus safety standard. It is based on IEC 60335-2-40, the international standard that currently serves as the basis for evaluating, testing and certifying HVAC equipment designs using low GWP refrigerants in Europe and elsewhere.
• UL/IEC 60335-2-89
  UL Solutions recently transitioned to the new harmonized Standard UL 60335-2-89, which covers UL 412, the Standard for Refrigeration Unit Coolers; UL 427, the Standard for Refrigerating Units; UL 563, the Standard for Ice Makers; and UL 471, the Standard for Commercial Refrigerators and Freezers. UL 60335-2-89 is harmonized with the IEC and covers all current market changes, easing global market access and simplifying testing for manufacturers.

Our safety science leadership, technical expertise and global network of testing laboratories can help you demonstrate compliance with regional safety standards for low GWP refrigerants in your target markets.

Certification path for boilers up to 25% hydrogen blending

The ninth edition of UL 795, the Standard for Commercial-Industrial Gas-Fired Package Boilers, is also a binational Standard, ANSI/CAN/UL 795:2024, Standard for Commercial-Industrial Gas-Fired Package Boilers for the U.S. and Canada.

UL 795 is the first North American Standard that offers manufacturers a path to certification for boilers using hydrogen blending up to 25%, setting a new benchmark for the industry.

UL 795 provides a certification path for hydrogen-natural gas blends as well as other traditional fuel types within its scope.

UL 795 now includes requirements for gas-fired package boilers, high-pressure steam and high-temperature water gas-fired boiler assemblies for fuel gases including natural gas, hydrogen-natural gas blends (up to 25% H2 and 75% natural gas blend shall be the limit for the purposes of this Standard), LP-gas, LP-gas/air blends, manufactured gas, furnaces and air heaters (U.S. only).
