Aqua-Hot Heating Systems, Inc. was founded in 1984 by Harold “Hap” Enander as Vehicle Systems, Inc. which manufactured and sold various RV accessories. Hap, being an RV enthusiast, was always looking for better RV solutions, one being a better way to heat his coach and water supply. He wanted quiet, evenly distributed heat and unlimited hot water when he had a continuous supply of water available. Because he was not able to find what he wanted, he designed and created his own system.


The Aqua-Hot hydronic RV heating system uses tubing to run hot liquid into heat exchangers that disperse heated air into living areas. Coils, with potable water running through them, wrap around the boiler to transport hot water to faucets and appliances. A variety of heat sources are used depending on the system, but all use some combination of the vehicle's engine surplus heat, diesel fuel or propane and AC shore power.


Aqua-Hot also produces the Work Ready™ line of hydronic heating systems for commercial fleets, school buses, industrial and oilfield applications. These systems are designed to accommodate diesel and alternative fuel vehicles (e.g. propane and natural gas) reducing engine wear, maintenance costs, and emissions while they abide by anti-idling laws.
