The Hydro-Hot Motor Coach Heating System is an on-board Hydronic
Heating System (heating with hot water) that provides a continuous, on-
demand supply of domestic hot water, as well as interior zone heating where
and when it is needed. Both heating features are accomplished by a unique
Diesel-Fired Burner and an AC powered Electric Heating Element (120 VAC).
These two heating sources maintain the temperature of the Hydro-Hot's
solution of water and antifreeze. In addition, the Hydro-Hot has been
designed to preheat the vehicle's engine prior to starting (HHE-200 Model
Only). This optional feature provides easy engine start-up whenever cool
weather conditions are present. Be sure to review Figures 1 and 2 for
complete component overview.
