Aqua-Hot Heating Systems Inc. (formerly Vehicle Systems, Inc.) was founded in 1989 when our company's owner had a vision of creating a superior heating system which did not yet exist in the RV market. Being an RV owner himself, he knew that many RV enthusiasts had higher expectations for their RV lifestyle and saw the need for another method of heating, which offered such creature comforts as unlimited hot water and quiet, evenly-distributed interior heat. His vision became a reality when his first heating system, the Aqua-Hot, was introduced to the high-end RV motorhome and coach conversion market in 1989. Within a few short years, the Aqua-Hot was standard or optional equipment on many high-end motorhomes from several major RV manufacturers of upper-end coaches. The success of the Aqua-Hot created a demand for a similar but smaller product that would meet the needs of the of class A diesel motorhomes where storage space was less generous. The Hydro-Hot (now our Aqua-Hot 450-D) was introduced in 1998 to meet this need. We foresee more growth in the future as we have some exciting innovations just around the corner.
