  • Reduce space usage with compact corrugated plate design ideal for tight installations

Superior build quality with 306 steel and brazed edges for high-pressure performance. Highly efficient heat transfer for energy savings in residential heating. Easy, tool-free installation into existing plenums.

Copper pipes may show minor water stains from manufacturing process. Requires cleaning water pipe cavity every 2-3 years and draining unused water. Needs 10-minute preheat with steam before fan startup to prevent damage.

Welcome to the premier destination for GPOAS heat exchangers, where efficiency meets durability in water-to-air solutions for forced air heating. These specialized coils, featuring 1-inch copper ports, are engineered for seamless integration with outdoor wood furnaces and residential heating setups, helping you maintain consistent warmth while maximizing fuel efficiency.

Why GPOAS Stands Out in Heat Exchangers

GPOAS has built a solid reputation for crafting robust heat exchangers that prioritize longevity and performance. What sets them apart is their use of high-grade copper tubing, which ensures superior heat transfer and corrosion resistance compared to standard materials. Whether you're upgrading your HVAC system or outfitting a new outdoor furnace, GPOAS products deliver reliable operation in demanding conditions. Their designs focus on ease of installation and minimal maintenance, making them a favorite among homeowners and HVAC professionals alike.

Key Features to Look for in GPOAS Heat Exchangers

When shopping in this category, prioritize these essential attributes:

  • Size and Capacity: Available in 20x20 and 12x15 dimensions to match your ductwork and heating demands.
  • Copper Ports: 1-inch connections for optimal flow and durability.
  • Construction: Robust coils built for water-to-air conversion, ensuring efficient heat exchange.
  • Compatibility: Tailored for forced air systems and outdoor wood furnaces.

These features make GPOAS exchangers versatile for residential applications, from supplemental heating to full-system replacements within broader building supplies.

Comparing GPOAS Models: 20x20 vs. 12x15

GPOAS offers two core models to suit different needs. The 20x20 heat exchanger provides greater surface area for higher heat output, ideal for larger homes or spaces requiring substantial BTU delivery. It's perfect for bigger outdoor wood furnaces where maximum efficiency is key. In contrast, the 12x15 model is more compact, fitting smaller setups like cabins or modular homes without sacrificing performance. Both share the same 1-inch copper ports and forced air design, but choose the 20x20 for expansive coverage and the 12x15 for space-constrained installations.

To see alternatives, explore options from brands like VEVOR Heat Exchangers or ALECOIL Heat Exchangers, which offer varying capacities within our Heat Exchangers collection.

Common Use Cases for GPOAS Heat Exchangers

These units excel in scenarios where hydronic heat needs conversion to forced air. Homeowners with outdoor wood boilers use them to distribute warmth through existing ductwork, reducing reliance on electric furnaces. They're also popular for garage workshops, greenhouses, or off-grid cabins. In residential heating, they integrate smoothly with boilers, providing zoned comfort. For those expanding into full tools & home improvement projects, GPOAS ensures your HVAC upgrade performs reliably year-round.
