Weil-McLain Furnace Replacement Parts
Weil-McLain is a respected name in the HVAC industry, known for its high-performance heating equipment and system components that prioritize reliability, efficiency, and long-term use. Core elements such as control boards, circulator pumps, and igniters are vital for effective heat distribution and system safety in both residential and commercial boilers.
Furnaces depend on components like flame sensors, thermostats, and gas valves to regulate output and ensure smooth operation. For oil-fired systems, the Weil-McLain Gold series is supported by specially engineered hardware that enhances fuel combustion and thermal transfer. AquaBalance units, designed for compact installations, rely on high-efficiency assemblies that manage both heating and hot water delivery. Cast iron gas appliances from the CGA line benefit from tailored solutions that maintain steady operation and meet safety standards. Likewise, gas-powered systems depend on precise controls such as pressure switches and fuel regulators to optimize energy use and maintain consistent temperatures.
At PartsHnC, we stock a complete range of Weil-McLain heating parts, gaskets, blower gaskets, orifice assemblies, & ignition control modules with full specifications and rapid shipping. We also provide trusted parts such as burner gaskets, water level gauge kits, actuators, water top pipes, and more.

Where is the Weil-McLain model number?
Your heating professional should have the CP number ready before contacting Weil-McLain technical support. The CP number is printed on a small rectangular barcode sticker located on either side of the boiler jacket.
What are the estimated costs for replacing a Weil-McLain boiler?
Typical replacement expenses range from $3,000 to $7,000, depending on the model, size, and installation complexity. For precise pricing, it’s best to consult a licensed heating professional.
How to tell a Weil-McLain boiler’s age?
To find the age of a Weil-McLain boiler, enter the 7-digit CP/serial number that begins with the letters "CP" to get the manufacturing date and related details. If the CP number has only 6 digits, add a leading zero after "CP" (for example, CP0123456) before entering it.
