What Does DSI Mean in an RV Water Heater?

What Does DSI Mean in an RV Water Heater?
A recreational vehicle is a great option for those who enjoy spending time outdoors but don't want to give up the creature comforts of home, including warm water. Most RVs come equipped with a propane gas water heater that can be lit each time you set up camp or a by direct spark ignition (DSI).


DSI means the water heater can be automatically lit by an electric switch inside the RV.


The switch activates the burner, which heats the water until it reaches a predetermined temperature. The burner will go out once it reaches this temperature and will only reignite when warm water is used inside the camper.


Direct spark ignition is safer and easier than using a pilot flame as the circuit board closes the gas valve immediately upon reaching the predetermined temperature. Most RVs are manufactured with this technology.


Many RVs are equipped with Atwood or Suburban direct spark ignition water heaters, and most range is size from 6 to 10 gallons.


For proper use, make sure there is water in the tank before use. It is also highly recommended that the switch remain in the off position during travel and periods of nonuse.
