AHE-100-02S
This service and parts manual is designed to aid
trained and qualified service technicians with
the process of troubleshooting and servicing the
Aqua-Hot AHE-100-02S Hydronic heating sys-
tem.
The Aqua-Hot AHE-100-02S heating system features a 12
Volt-DC powered diesel-burner and a 120 Volt-AC, 1650
Watt electric heating element. These two heating sources are
used in conjunction with an antifreeze/water heating solution
in order to provide a continuous supply of domestic hot wa-
ter, interior/fresh water tank heating, independent interior
zone heating, and engine preheating. Be sure to reference
Figures 3 for a complete component overview.
Please note that all Danger, Warning, Caution, and Note box-
es, appearing as needed throughout this manual, must be
reviewed and adhered to during any service procedure in
order to avoid potential hazards, which could result in injury,
product damage, or property damage.
Should additional assistance be needed, please contact the
technical support department at 1-800-685-4298, Monday
through Friday, between the hours of 7:00 AM and 4:00 PM
Mountain Standard Time.

Understanding the Aqua-Hot AHE-100-02S Major
Systems:
The basis for the Aqua-Hot heating system’s functionality is
the antifreeze and water heating solution, which is comprised
of water that is distilled, de-ionized, or soft, as well as anti-
freeze. Through this solution’s ability to maintain and trans-
fer heat, the Aqua-Hot’s three major systems: the domestic
water system, engine preheat system, and interior heating
system, are able to function effectively. This antifreeze and
water heating solution is contained within the Aqua-Hot’s
boiler tank and is heated by the diesel-burner when its oper-
ating criteria are met and/or the electric heating element
when its operating criteria are met. In order for the diesel-
burner to be considered as a heating source by the Aqua-Hot,
it must have an adequate fuel supply, receive power from the
fuse block, and be selected as a heating source from the inte-
rior switch panel. In order for the electric heating element to
be considered as a heating source by the Aqua-Hot, it must
receive power from either a generator or from shore power
and be selected as a heating source. Once the antifreeze and
water heating solution achieves operating temperature (as
determined by the Aqua-Hot’s control thermostat), the do-
mestic water system, the engine preheat system, and the inte-
rior heating system are permitted to operate as needed.
Domestic Hot Water System:
When hot water is requested, domestic water from the motor
home’s fresh water tank is transported through a copper coil
around the Aqua-Hot’s boiler tank where heat is transferred
from the heated antifreeze and water heating solution to the
domestic water flowing through the copper coil. The heated
domestic water then flows through the tempering valve to be
mixed with cool water from the fresh water tank to achieve
an appropriate temperature before it flows to the faucet re-
questing hot water.
