Heat exchanger sourcing for gas water heater OEM programs
The heat exchanger is a critical component for heat transfer, water-path compatibility, and long-term service performance. Buyers should compare more than material names: dimensions, tube arrangement, connection position, wall thickness, weight, burner match, and the intended water-quality conditions all matter.
What to confirm before sampling
- Heater capacity range and forced or balanced exhaust design
- Copper material option and required coating or surface treatment
- Overall dimensions, tube layout, inlet/outlet position, and mounting points
- Sample approval method, leak testing, and packaging protection
- Expected annual quantity and replacement-parts demand
We can review a drawing, original sample, or heater model before preparing an OEM component quotation. Product selection and final testing should be completed against the target heater design.
