Get a focused repair option when a technician confirms the heat exchanger in your Hayward H200FD heater needs replacement. This genuine Hayward assembly transfers heat from combustion to circulating pool or spa water, replacing the exchanger rather than the complete heater.

It is designed for the 200,000 BTU/hr Universal H-Series Low NOx FD platform, including H200FDN natural gas and H200FDP propane models. Check the full model number and service-parts diagram before ordering; older H-200 Millivolt, ED1 and ED2 heaters use a different assembly.

• OEM replacement: A manufacturer-identified part helps you match the replacement to the compatible H200FD configuration.
• Plastic header: The assembly has the plastic header configuration listed for this heater platform.
• Targeted service: Replacing the exchanger can leave other serviceable heater components in use after professional inspection.
• What’s included: One replacement heat exchanger assembly; the complete heater, burner assembly, gas valve and electronic control system are not included.
• Product size: Listed product weight is 33 lb, with shipping dimensions of 30 × 18 × 8.5 inches.
• Technician installation: Have a qualified pool heater technician follow Hayward’s service instructions and inspect related connections, seals, safety components and heater condition.

Ask your technician to identify the cause of exchanger damage before reassembly. This replacement does not increase the heater’s rated capacity or correct unrelated operating faults, so it’s best suited to a confirmed exchanger repair.
