Atwood GCH10A-4E
Gas Combo (electric) Heat exchanger 10Gal 4th version Electronic Ignition
Atwood GEH16-EXT
Gas Electric Heat Exchanger 10gal tank but 16gal equivalent (due to high temp and mixing valve)
Suburban SW10DEM, SW12DEM, SW16DEM
Gas/Electric in 10,12 or 16 gal tanks with Motor-Aid and electronic ignition
Heat Exchanger/Motor-Aid
1/2" tube attached to tanks that Hot Engine Coolant flows thru heating the water as you drive
2 hrs drive time will yield roughly 130*F water temps
*longer drive times doesn't cause HIGH water temps....1/2" tube/coolant flow can only transfer just so much heat)
