I

NTRODUCTION

 

The Aqua-Hot Heating System is a Low Emissions Hy-
dronic Heating System (heating with hot water) that sig-
nificantly improves your level of comfort, is good for the 
environment and adds thousands of dollars in value to 
your RV. 
 

The Aqua-Hot Heating System is actually four sys-
tems in one:

 

• 

Interior heating system providing quiet, comfortable 
interior heat with independent temperature zones that 
provide cabin-wide even temperatures. 

• 

Bay heating system keeps pipes and tanks from 
freezing in the bay storage area. 

• 

Tank-less hot water system provides a steady flow of 
continuous hot water. 

• 

Engine preheating system reduces engine wear 
caused by cold starting by preheating the engine 
from 30°f to 90°f in one hour. 

 

Your Aqua-Hot System is powered by TribridHot

 

technology, using one or a combination of sources:

 

• 

The Vehicle’s Engine: When driving or idling, the en-
gines surplus heat is transferred to the Aqua-Hot pro-
viding interior heat and limited hot water without 
burning any other fuel.   

• 

The 120v AC Electric Element: When plugged into 
shore power, the electric element lets you use the 
power you are already paying for to provide interior 
heat and meet your light duty hot water needs. 

• 

The Diesel Burner: The Aqua-Hot’s most powerful 
heat source provides all of your heating and hot wa-
ter needs in really cold temperatures or when dry 
camping. 

 
You can even combine power sources. TribridHot

. It’s 

technology at it’s warmest.
