Engine Block Heaters For RV Generators

There are several types of generators made. An RV generator must be used in any enclosed compartment. RV generators are set up with a cooling system, air intake, and exhaust system to follow code restrictions for RV’s. Stand alone generators can not be used in RV’s. There are a variety of companies that make RV generators. I will refer to Onan in this article. Other makes use similar designs. There are 3 fuels used for generators: gasoline, diesel, or propane. Gasoline and propane use a very similar and sometimes identical engine. Diesel generators are typically larger, use a larger engine and have a higher electrical output. Gasoline and diesel generators are matched to the RV’s engine fuel. Propane generators are typically used in diesel coaches to keep costs down. (Propane generators are much less expensive than diesel generators) RV Generators in motor homes typically use the coach batteries for power. They have an electric starter and usually a remote start panel inside the RV. Once started, they have a DC charging system to charge the coach batteries. The DC charging system has a low amperage output in comparison to the coach engine’s alternator.
