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 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 commerical applications.
