Remanufacturing Information

Aqua-Hot Heating Systems, leader in on- and off-highway vehicle hydronic heating, introduces a new program covering many of its Aqua-Hot and Hydro-Hot products that were manufactured over the past 30 years.  Now, coach owners can have their Aqua-Hot units remanufactured with improved technology, at a cost significantly lower than a new system

The remanufactured Aqua-Hot system is given a new serial number. It includes many replacement components, such as the tank and cabinet. The new tank is equipped with a low emission burn chamber, reducing emissions by eliminating up to 80% of total hydrocarbons. This provides a smoke- and odor-free environment for coach owners and their neighbors.

The burner is rebuilt. An improved temperature tempering valve and internal coil improve heat transfer providing enhanced hot water performance. All other components are checked for functionality. The remanufactured units are zero-pressure systems that use safer propylene glycol.

Once completed, the units are thoroughly tested and inspected for all operations. A new one-year Aqua-Hot Heating Systems factory warranty is included.
