Aqua-Hot 600D and 675D Features
The Aqua-Hot Heating System is a low-emissions Hy-
dronic Heating System (heating with hot water) that signifi-
cantly improves your level of comfort, decreases harmful emis-
sions released into the atmosphere, and adds thousands of
dollars in value to your coach.
The Aqua-Hot Heating System is four systems in one:
1. Interior Heating System
The Aqua-Hot provides quiet, comfortable interior
heat with independent temperature zones that en-
sures even temperatures when requested, and where
requested throughout the cabin.
2. Bay Heating System
Keep pipes and tanks from freezing in the bay stor-
age area.
3. Tankless Hot Water System
The tankless design of the Aqua-Hot ensures that
continuous hot water will be supplied whenever it is
requested
4. Engine Preheating System
Reduces engine wear due to cold starting by pre-
heating the engine from 30°F to 90°F in one hour
The Aqua-
Hot System is powered by TribridHot™ technology
TribridHot™ technology allows the Aqua
-Hot to heat
from one of, or a combination of the following heat sources.
1. AC Electric Elements
When plugged into shore power, or operating on a
generator, the AC Electric Elements may be utilized to
provide heat for light duty heating and hot water
needs.
2. Diesel Burner
The diesel burner serves as the primary and most
powerful heating source for the Aqua-Hot, and will
provide adequate heat for all ranges of heating and
hot water needs.
3. Vehicle Engine
When driving or idling your coach, the engine’s sur
-
plus heat is transferred to the Aqua-Hot, providing in-
terior heat and limited hot water without burning addi-
tional fuel.
