The Most-Economical System
Aqua-Hot 375-D
Want warm interior heat and continuous hot water, but don’t have a
need for engine preheating? This is our most economical unit,
which has the ability to keep the interior of your
home-away-from-home warm and provide continuous hot water using
power from both its diesel burner and its electric element.
Although the electric element can be used by itself for light use
during mild temperatures, for continuous hot water and heating
during chilly temperatures, this unit relies on its diesel burner to
meet these needs. If you’re looking for an economical heating
system without engine preheat and have diesel fuel readily
available, this is the unit for you!
