The Propane-Powered System
Aqua-Hot 375-LP
Love the features of the hydronic heating
systems on the Class-A diesel motorhomes, but have a gas-powered
recreational vehicle, towable, or park model? This economical and
propane-powered heating system has the ability to keep the interior
of your home-away-from-home warm while also providing continuous hot
water using power from both its propane 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 propane
burner to meet these needs. If you’re looking for an economical
hydronic heating system without engine preheat and have a
gas-powered RV, towable, or park model, this is the unit for you!
