Section 8: Plumbing System
 Tankless Hot Water System: Provides a steady flow of continuous hot water.
The Aqua-Hot system utilized one or a combination of the following heat sources:

Burner: This is the Aqua-Hot’s most powerful heat source. The burner must be on
for the Aqua-Hot to provide continuous hot water. The burner must be on for the
Aqua-Hot to provide interior heat in colder conditions.

120VAC Electric Element: When plugged into shore power, the electric element
lets you use the power you are already paying for to provide heat in mild condi-
tions and meet your light duty hot water needs.
Your Aqua-Hot hydronic heating system heats a propylene glycol antifreeze and distilled
water solution that is stored in the Aqua-Hot’s boiler tank. This water and antifreeze solu-
tion must be up to operating temperature before the Aqua-Hot will provide interior heat or
comfortable hot water. To bring the Aqua-Hot up to temperature, turn the Burner to the ON
position. Depending on the ambient temperature, it may take up to 10 minutes for the Aqua-
Hot’s water and antifreeze solution to reach operating temperature. Once the tank is up to
operating temperature, the electric element may be used to maintain the operating tempera-
ture and provide light duty hot water and interior heat. For continuous hot water, or for heat
in colder conditions, it is recommended to utilize the burner.
Tank-less Hot Water System
For hot water use, select and turn on one of the heating
modes on the Aqua-Hot switch. Be sure there is power to the Aqua-Hot appliance and water
in the system. Allow sufficient time for the appliance to heat the water for your needs (ap
-
proximately 10 minutes). To run water at the faucets, make sure the 12 volt pump is on or the
city water connection is hooked up, the tank fill/city fill valve should be set to city fill, and
the supply faucet is in the ON position. For continuous hot water the burner should be used.
Heating System:
Select the mode you wish to use on the Aqua-Hot control switch.To de-
termine which mode you wish to use, consider that the Aqua-Hot Burner will provide more
BTUs for heating in colder weather while the electric can warm the unit in cool temperatures
that require less demand for heat. To utilize this heat mode, turn on the thermostat and set the
furnace mode to the temperature you desire. In cold weather, you may need to use the Aqua-
Hot Burner mode to bring the heating temperature up to heating temperature. Note that, in
extreme cold temperatures, the Aqua-Hot Burner may be needed to supplement heating of
the antifreeze heating solution.
The electric element is the secondary heat source and can be used when plugged into shore
power. The electric element provides heat when moderate outdoor temperatures exist (50°F
or higher) or if there is a low demand for hot water. It is activated by turning the Aqua Hot
Electric switch on.
Operating Instructions
The Aqua-Hot Heating System provides interior zone heating as well as a continuous, on
demand supply of domestic hot water. Both heating features are accomplished by a 12 Volt-
DC powered Diesel-Burner and a 120 Volt-AC powered electric heating element, which
maintain the temperature of the Aqua-Hot’s antifreeze and water heating solution.
Activating the Aqua-Hot Heating System
Turn the Burner switch
ON
. This will activate the Burner and the indicator light on the
burner switch. Allow 10-20 minutes for the Aqua-Hot System to reach operating tempera-
ture. Note that the Diesel-Burner is the
primary heat source
for heating both the interior
and the domestic hot water (when cool ambient temperatures exist and/or when there is a
high demand for domestic hot water).
Electric Heating Element
™
NOTE: Must be plugged into shore power or have generator running to
operate.
