How long have Hydroheaters been around?
The technology behind direct steam injection was developed in 1911. Inventors John White and Roy Miller patented heating equipment using steam to precisely control water temperature in 1927. Manufacturing industrialist, Harry Schauer invented the Hydroheater in 1934 for use in a paper mill in Wisconsin.

Today, more than 80 years after the Hydroheater was invented, Hydro-Thermal has taken the technology and expanded its application across diverse industries.
