System Overview
The Aqua-Hot 200 Diesel Series is a Hydronic (water-
based) Heating Systems that can provide heat and tank-less,
continuous hot water in one small, easy to install package.
The Aqua-Hot Heating is a 2-in-1 System
1. Interior heating system: provides moist, quiet, comfortable
interior heat and even temperatures. It is equipped with
one thermostatically-controlled temperature zone.
2. Tank-less hot water system: provides a flow of continuous
hot water. It produces 90 gallons per hour (1.5 GPM).
The system uses one or a combination of heat sources to
heat FDA-approved “Generally Recognized As Safe” (GRAS)
propylene glycol based antifreeze solution contained within
the Aqua-Hot boiler tank.
The 250-D03 uses a 12-volt DC powered diesel burner
as the primary heating source. The diesel burner should be
used as the primary heating source for hot water and interior
heating needs. The 250 also has one 120-Volt AC 1000-Watt
electric element for use (when shore power is available) as a
supplemental heating source. Once the tank has been brought
to operating temperature by the diesel burner, the electric
element can be used to maintain this temperature, as well as
provide hot water and interior heat for light-duty applications.
The burner and the electric element can be used together or
separately.
For continuous hot water or heat in colder conditions, it is
recommended to utilize the diesel burner. The electric heating
element will provide heat only in mild conditions and provide
light duty hot water needs.

NOTE:
For networked control of the Aqua-Hot Controller,
Aqua-Hot requires system integrators ensure that individual
commands are received and processed. Aqua-Hot requires
that commands be repeated or confirmed so that if a
single message were dropped, or if there is a brief network
disturbance, the Controller would get into the correct state
as soon as the disruption was removed.
The Aqua-Hot Controller monitors the heating system and
handles all logic relating to safeties and heating control.
As such, the system integrator is required to display all
pertinent status information but not use that information to
lock out operation or add additional safety layers that could
impact the end of operation if a message from the Controller
was missed.
NOTE: The Aqua-Hot LCD Screen is optional. The coach
may be equipped with a coach LCD with the RV-C network
communication. Either will work with the Aqua-Hot system
and the display screens will be similar. The screens will be
referred to as “LCD Screen” or “interior/coach control panel”.
