Engine Heat Exchange System
The engine heat exchange system allows a motor home to heat the water while traveling. This convenient
option allows you to arrive at your destination with hot water. Operating a pilot or electronic water heater on
gas while in transit is a dangerous practice.
This system consists of a U-shaped aluminum tube that is attached to the outside of the tank with welds. SAE
hoses are attached to both ends of this tube and are spliced into the engine coolant system.
When the engine is running, the hot coolant flows past the tank through this tube and by means of heat
transfer through the welds, heating the water. The design of this system will not allow the water to reach a
boiling point.

• When Aftermarket heating elements are inserted
into the drain plug, customers are more prone not
to flush their tanks. Not flushing the tank
accelerates tank corrosion on both our pilot and
electronic ignition water heaters creating a situation
where the tank may have to be replaced.
