VEVOR Water to Air Heat Exchanger, 14 x 14 in Finned Tube HVAC Heat Exchanger Coil with Copper Tubes & Aluminum Fins, 65K BTU Output for Outdoor Wood Furnace, Hydronic Heating & Cooling Systems

Aluminum Fins and Copper Tubes for Optimal Heat Transfer Effectiveness

The VEVOR water to air heat exchanger uses aluminum fins and pure copper tubes. This unit transfers thermal energy from water to air with little loss because copper conducts heat more quickly than most metals. As a result, your space will stay warm and comfortable without your heating system working extra hard.

The aluminum fins increase the contact surface between the coil and the flowing airstream by firmly encircling the copper tubes. With this arrangement, the exchanger efficiently extracts the most energy from the hot water passing through the tubes and transfers it to the air. This copper-and-aluminum design provides reliable heat-transfer performance year-round, whether you operate a commercial or residential setup.

Water to Air Heat Exchanger with 65K BTU Capacity for Strong Heating Output

With a heating capacity of up to 65,000 BTU per hour, this device is among the most capable choices for light commercial and residential applications. That production level easily handles large farm shops, roomy garages, and open-plan commercial floors. Even when the outside temperature drops considerably, you still get quick heat-up periods and long-lasting warmth.

The 65K BTU rating reflects real-world performance under typical operating settings, not just peak laboratory statistics. To extract as much energy as possible from the circulating water, the water to air heat exchanger uses the full surface area of its 169-fin coil. When you combine it with an appropriately sized boiler and pump, you get a heating system that continuously and effectively operates at its rated capacity during the heating season.

Water to Air Heat Exchanger: 14 x 14 with 169 Fins and 3-Row Copper Tube Design

This exchanger has a large surface area, enabling strong airflow interaction across the entire coil face, thanks to its effective heat-transfer area of 14 x 14 in. The unit produces hundreds of narrow air channels that significantly increase the thermal exposure between the heated coil and the airstream by packing 169 separate aluminum fins across that surface.

Three rows of 3/8-inch seamless copper tubes, arranged to maximize contact time within the coil, run through the fins. By eliminating weak spots along the tube walls, seamless construction reduces the risk of leaks under pressure. This three-row design keeps your system operating at maximum thermal efficiency by ensuring that water passing through the exchanger releases as much heat as possible before returning to the boiler.

Epoxy-Coated Aluminum Fins for Long-Term Durability and Scale Resistance

VEVOR uses high-hardness epoxy-coated aluminum fins to directly address scale accumulation, one of the most frequent causes of heat exchanger failure. Between the fin surface and the water vapor or minerals that flow through the system, the coating forms a protective barrier. This feature helps the unit maintain steady airflow and thermal performance after years of operation and keeps the fins cleaner for longer.

This unit can withstand both freezing winters and high-output heating requirements without material fatigue, as its operating temperature range is -40 to 356 degrees Fahrenheit. The exchanger has a long-lasting construction profile thanks to the combination of epoxy-coated fins and pure copper tubing. You spend more time enjoying the benefits of a system that consistently performs well season after season and less time on maintenance.

High-Pressure Vacuum Brazing for a Sealed and Leakproof HVAC Heat Exchanger

VEVOR manufactures this HVAC heat exchanger using high-pressure vacuum brazing technology, which uses a controlled vacuum to fuse copper tubes to aluminum fins. Compared to conventional soldering, this technique produces stronger, cleaner joints and eliminates voids or weak areas. To ensure you receive a product ready to perform under pressure right away, every unit also undergoes extensive leak testing before leaving the facility.

This exchanger can confidently handle demanding hydronic systems due to its maximum operating pressure rating of 2.5 MPa (362.6 psi). Heating system leaks result in water damage, pressure drops, and costly efficiency losses. The vacuum-brazed construction eliminates that risk and provides a sealed, reliable unit that maintains pressure without requiring regular checks or urgent repairs.

Wide Compatibility with Outdoor Wood Furnaces, Hydronic and Forced-Air Systems

One of the most adaptable coils in its class, this water to air heat exchanger works with a variety of heating configurations. It is compatible with forced-air heating systems, greenhouses, large farm shops, outdoor wood furnaces, hydronic heating systems, and hybrid systems integrating multiple heat sources. Without the need for specialized adapters or significant modification, the 1.1 x 1.4 port size connects to regular plumbing lines.

This item is simple to integrate into current systems for both installers and do-it-yourself homeowners. It can fit into narrow duct layouts while maintaining full output performance thanks to its compact dimensions of 19.3 x 14.0 x 3.5 in. Its weight of 12.6 lbs makes it manageable and easy to position without bulky equipment. This exchanger delivers the output, build quality, and installation flexibility you need for reliable heat distribution over a wide area.
