Aqua-Hot Heating Systems, Inc.

Information may not be reliable

Engineered for RVs, the quiet, economic system did indeed supply moist, even interior heat and continuous on-demand hot water when hooked to a continuous supply of water. 

It also provided engine preheating reducing wear and tear at engine start up. Hap called it the Aqua-Hot Heating System® and it revolutionized the RV heating industry. 

The story of the company’s evolution unfolds from there.

With such a great product, Hap knew other RVers would love it, so he hired additional employees and began product development and enhancement, resulting in a smaller unit a few years later called Hydro-Hot.
