AERCO is a leading manufacturer of cost-effective, commercial condensing boilers and water heaters for a variety of industries including Education, Healthcare, Hospitality, Government and Military, Industrial, Multifamily Housing, Office Buildings and more. Our system-design approach enables us to provide customer-specific solutions that deliver superior building performance at a lower operating cost while assuring uptime reliability.

It all started with a vision.

When Henry Angelery founded AERCO as Angelery Engineering Research Company in 1949, his goal was to deliver on-demand temperature-controlled water heating without storage. That vision became a reality when AERCO introduced an innovative design for an indirect-fired water heater – and it revolutionized the water heating industry.

AERCO continued to innovate and in 1988, introduced the first condensing and fully modulating boiler and water heater to the commercial market. The modulating capability of these products, still unsurpassed more than 30 years later, matches the equipment’s output to real-time heating demand, ensuring the units draw no more fuel to operate than is absolutely necessary. This not only saves precious energy, but also ensures money doesn’t needlessly disappear “up the stack.”

AERCO differentiates itself through a solution-based model, leveraging decades of engineering experience and industry application expertise to understand each customer’s unique needs. By partnering with customers and end-users to understand their project-specific requirements, AERCO provides tailored application solutions that are comprised of original product technologies including high efficiency products, compact footprints, high turndown ratios, unique fuel delivery, leading control systems and proprietary design elements that combine to deliver up to 99% efficiency.

In 2011, AERCO relocated its corporate headquarters to Blauvelt, New York in a 163,000 sq. ft. state-of-the-art manufacturing facility with a 12,000 sq. ft. AHRI accredited Engineering Laboratory. AERCO’s world-class operation supports differentiated manufacturing competencies, including highly specialized brazing and welding, driving superior product performance and increased design flexibility. AERCO has built its operations around the Lean Value Stream concepts, where cross-functional teams focus on adding value in the most efficient manner.

AERCO’s success and engineering strength is a direct reflection of its people. In addition to a large product development team, we have manufacturing and quality engineers on the shop floor and throughout the company’s sales and executive staff. We have a dedicated team of union employees who build and manufacture our products on site. AERCO also has a nationwide network of highly skilled sales representatives to help customers leverage the advantages of AERCO equipment through the overall system design.

“Engineering Research” is embedded in AERCO’s name, identity and philosophy. Throughout its 70-year history, AERCO has continually striven for excellence which has resulted in a number of industry firsts and cemented its position as a technology leader.
