Angelery Engineering Research Company (AERCO) is a leading supplier of boilers and water heating products, and the originator of semi-instantaneous water heating.
AERCO was founded in 1949 to design an indirect fired water heater that heated water on demand without storage and at a controlled temperature. This innovation predicted the future of water heaters. With continued improvements on this design, our engineering people have been able to maximize the recovery of latent heat energy and accurately predict the temperature of the sub-cooled condensate.
