The Aqua-Hot heat system is specially designed for use in motorhomes. The
Aqua-Hot is an appliance combining a water heater with a furnace. The Aqua-Hot
will provide an almost endless supply of hot water and heat the interior of the
motorhome. A 50,000 BTU diesel fired burner and a 1,650 watt AC element heats
a 50/50 antifreeze solution to approximately 200º F. The antifreeze solution is
pumped through heat exchangers located throughout the motorhome. Four pumps
are used to circulate the antifreeze solution. Three pumps supply the solution to
the interior heat exchangers. The fourth pump circulates the antifreeze solution
through the engine. Fresh water is heated when pumped through a coil tube inside
the Aqua Hot.
Chlorine bleach or other concentrated chlorine bearing chemicals can cause
failure to the Aqua-Hot’s Domestic Water Loop (copper tubing) if not properly
and thoroughly rinsed. The Aqua-Hot’s copper tubing is rated for use with fresh
water and winterization solutions only. Periodic flushing with common household
chemicals, including bleach, has little or no effect on the heating system if prop-
erly rinsed with the fresh water afterwards. Failure of copper tubing, especially
soft or flexible copper, can result if materials other than water or winterization
solutions are allowed to reside inside the piping for extended periods as during
storage or other periods of non-use. The most common cause for failure is due to
an extended exposure to chlorine, solutions containing chlorine (i.e. bleach) or
hydrochloric acid.
NOTE: The Aqua-Hot must be turned ON before using any heat
feature. One of the following switch panels is used in your
motorhome.
Diesel Burner
The diesel burner will consume approximately ½ gallon of diesel for each
hour of continuous burner operation. The diesel burner is rated at 12 Volt/65
watts. Three circulating pumps are rated at 12 Volt/12 watts each. The diesel fired
burner has a fast recovery rate. To heat the Aqua-Hot from the diesel burner turn
the switch to the ON position. The switch will illuminate when the Aqua-Hot is
ON. Allow 20-30 minutes for the Aqua-Hot to reach operating temperature before
operating heat exchangers or using hot water.
