Steam-To-Water Heaters

In 1949, AERCO’s founder, Henry Angelery, had an idea for a water heater that offered accurate temperature control without storage tanks. From this idea, he designed and manufactured the world’s first compact, tankless water heater – paving the way for the thousands of semi-instantaneous and instantaneous heating units that are available today. Based on Angelery’s original concepts for the heat exchanger design, fully modulating steam input and temperature-control approach, this time-tested design has been consistently improved by AERCO to meet the needs of a wide variety of commercial applications.
