Raypak 005254F – Tube Bundle Assembly – 335 Heater Series
If your 335 heater is firing normally but taking too long to heat, leaking internally, or leaving scale and moisture inside the cabinet, the tube bundle assembly is one of the first major components to inspect. This is a common failure point when a Raypak heater is not working efficiently even though the burner side still looks functional.
This tube bundle assembly carries water through the heat transfer section of the heater so combustion heat can move into the system. When the bundle becomes scaled, restricted, or starts leaking, heater output drops and internal damage can spread. Replacing it restores the core water-side heating path inside the unit.
- Heater runs but water temperature rises slowly
- Internal leakage develops around the exchanger section
- Scale or corrosion is found during teardown
- Raypak heater troubleshooting points to heat transfer failure
What this part does: It forms the internal tube bundle assembly that transfers heat into the circulating water.
Compatibility: Designed for Raypak 335 heater series. Confirm with your model number before ordering.
- Part Number: 005254F
- Type: Tube bundle assembly
- Application: 335 heater series
OEM Value: A genuine Raypak replacement part helps maintain the intended fit and internal water path. Major exchanger repairs go better when the bundle assembly matches the original heater configuration.
