About Marley Engineered Products

For more than four decades, Marley Engineered Products has been a cornerstone name in electric comfort heating and ventilation. Marley Engineered Products operates its manufacturing facility in Bennettsville, South Carolina, with regional sales representation spanning the entire United States and an administrative office in Burr Ridge, Illinois. As a business unit of SPX Technologies, Marley carries forward a legacy of engineering reliability and energy efficiency that architects, contractors, engineers, and homeowners have depended on since the brand's founding.

Trusted Brands Under One Roof

Marley Engineered Products is the parent company behind several industry-respected sub-brands. QMark® is recognized for high-quality electric heating and ventilation products designed for both residential and commercial spaces, with a focus on efficiency and long-term durability. Berko® brings a similarly broad portfolio — from baseboard and wall heaters to infrared units — earning a reputation for reliability in demanding commercial and industrial environments. Fahrenheat® and Leading Edge® round out the lineup with specialized portable heating and commercial ceiling fan solutions respectively, ensuring Marley has a product suited to virtually every application.

A Complete HVAC Component Ecosystem

What sets Marley apart from many heating brands is its depth of engineered components beyond the finished heater. The brand manufactures and supplies the critical internal parts that keep HVAC systems running at peak performance. At the heart of many Marley unit and wall heaters are purpose-built HVAC blower motors engineered for consistent airflow delivery and quiet operation across multi-speed configurations. Complementing these are dedicated HVAC heater fan motors matched precisely to Marley's own heater models, making OEM replacements straightforward and reliable.

Precise temperature control is equally central to Marley's philosophy. The brand offers a range of line voltage thermostats — including single-pole and double-pole configurations — designed to interface directly with their electric heaters for accurate, energy-conscious comfort management. Supporting the electrical infrastructure within these systems, Marley's transformers provide dependable voltage conversion and power regulation, while their HVAC relays — including 24V fan relays and fan auto-relays — ensure safe, responsive switching between heating modes and fan operation.
