Eemax was established in 1988 with a line of tankless water heaters for commercial applications ranging in size from .5gpm to about 1.5gpm. The original Eemax technology was patented and quickly emerged as the most flexible technology on the market.

Eemax’s first product, the 9.5 kW Flow Control, was developed in 1989 as a simple on/off device for handwashing applications. This patented modular design led to other units with electronic thermostats, adjustable flow, and up to 277 volt capacities, which expanded the market for electric tankless heaters by the early 1990s.

Eemax expanded its market leadership position throughout the 1990s by introducing the new Eemax line of Series Two and Series Three water heaters, a wider range of hot water commercial applications that covered from 1.5 up to 5 gpm.

In 2000, Eemax introduced a line of residential products so consumers could enjoy the benefits of tankless water heating. Over the last ten years Eemax has established a leadership position in the residential market to complement its commercial business.

In 2003, Eemax further enhanced its position of the dominant supplier for commercial applications with the introduction of its patented Series Six and Series Twelve family of high capacity water heaters. These products are designed for commercial and industrial applications from 6 to 25+ gpm. In addition, there are models within this product category specifically designed for point-of-use emergency safety equipment applications, including safety eye, face and shower systems.

Eemax was purchased by the private equity firm Riverside, in 2008. Giving Eemax the capability to expand its product breadth and hold on the marketplace.
