Robertshaw Heating Parts & Accessories: A Century of Precision Controls

When a furnace refuses to fire, a water heater runs cold, or a gas valve needs replacing, technicians and serious DIYers alike reach for Robertshaw — and for good reason. Heating parts and accessories represent the very heart of what Robertshaw has done since its founding in 1899, when Frederick W. Robertshaw invented one of the first thermostatic controls for gas water heaters. That heritage of precision and safety engineering runs through every product the company makes today.

What Sets Robertshaw Apart in Heating Controls

Robertshaw is not simply a parts supplier — it is a global engineering and manufacturing company whose entire product philosophy is built around safety, reliability, and efficiency in thermal management. With more than a century of manufacturing experience behind them, Robertshaw's heating parts are designed to meet the exacting demands of both residential and commercial systems, including gas furnaces, water heaters, boilers, and space heaters.

Their engineering team has remained focused on meeting government regulations for intricate heating system components while delivering solutions that service technicians can trust in the field. The result is a lineup of heating parts that professionals specify by name — not just as generic replacements, but as the preferred choice for long-term performance.

Key Heating Product Lines

Robertshaw's heating parts catalog covers the critical components that keep gas heating systems running safely and efficiently:

• Gas Valves: Robertshaw's Unitrol series gas valves are industry-recognized controls used to regulate and isolate gas flow in furnaces, water heaters, and boilers. Models are available with or without a gas cock, in regulated and non-regulated configurations, with standard features including pilot outlet, pilot gas filter, and pilot adjustment. The 1751 Series Add-on Pressure Regulator Kits even allow technicians to convert OEM gas valves from natural gas to propane in the field.
• Gas Thermostats: The GS Series snap-acting hydraulic thermostat provides temperature control by interrupting gas flow to the burner and is suited for a wide range of applications including space heaters, warming cabinets, and fryers. The BJWA Series combines a gas cock and bypass thermostat in one unit, allowing gas activation and temperature setting with a single turn of the dial.
• Hot Surface & Ignition Controls: Robertshaw offers hot surface igniters, spark ignition modules, and universal ignition modules designed for reliable burner startup — critical components that, when they fail, bring an entire heating system to a halt.
• Electric Water Heater Thermostats: The 5600 Series electric water thermostats combine automatic cycling and high-limit protection in a single compact housing, designed for straightforward replacement on domestic and commercial water heaters. The WH9 Series electric thermostat is a surface contact device for tanks heated by electric heaters or solar systems.
• Flame Sensors & Transformers: Robertshaw's flame sensors and Class 2 transformers round out their heating accessories lineup, providing essential safety and power-supply components for modern HVAC and ignition systems.

Trusted by Technicians, Engineered for Longevity

Robertshaw thermostats are built with nickel-plated brass housings for durability, and programmable models include energy-saving setpoints that help reduce fuel consumption over time. Many controls are engineered as "Uni-Kit" universal replacement solutions, meaning a single part can cover a wide range of OEM configurations — reducing truck-stock requirements and speeding up service calls. Whether you are a professional HVAC contractor or a homeowner tackling a DIY repair, Robertshaw's heating parts deliver the precision and dependability that a critical home system demands.
