Restore heat transfer in a compatible Hayward H-200 pool heater with this genuine Hayward heat exchanger assembly. It replaces the heater’s water-heating component, helping address a failed exchanger without replacing other serviceable parts.

It is designed for H-200 Millivolt, Electronic ED1, and Electronic ED2 heaters. Before ordering, have a qualified technician match your heater’s complete model and generation to the correct parts diagram.

• Genuine Hayward replacement: This model-specific assembly provides an OEM option for servicing compatible H-Series equipment.
• Targeted repair: Replace the heat exchanger when a technician identifies it as failed and confirms the rest of the heater is suitable to keep using.
• Compatibility matters: It is not for every heater marked H200, Universal H-Series FD heaters, or other heater sizes.
• One assembly included: This is a replacement part, not a complete heater; confirm any additional components needed for your heater revision.
• Shipping size and weight: 8.5 × 17.5 × 26 inches; 36.76 lb.
• Replacement-part warranty: 1 year, subject to Hayward’s terms.

Professional installation is recommended because replacement involves a gas-fired appliance, water connections, and safety components. Before fitting the assembly, the technician should investigate the original failure and assess water chemistry, circulation, and heater operation. Follow Hayward’s service instructions and verify proper operation before using the heater again.
