Standard series

You can buy an Atwood water heater with one of the three lighting options, all of them with advantages and disadvantages:

  • Atwood RV water heater with the electronic ignition lights the heater by using the simple switch, which is located inside the RV, for convenient use.
  • Pilot re-light ignition - has to be manually lit while it automatically re-lights when extinguished by the wind.
  • Pilot ignition - has to be manually lit also, when the destination has been reached. It takes half an hour to have the water hot.

There are two tank sizes (capacity) you can choose from; 6-gallon and 10-gallon and the heaters are using the gas burner with the gas input of 8,800 BTU and 10,000 BTU and if combined with the electric heating, there is 1400 watt heating element installed.

Atwood RV water heater is mainly using propane gas or LP for heating. They can also operate from an electric source, off an electrical hook-up or a generator, with the RV's engine-cooling system and combining two fuel sources.

Great advantage is when the water heater is using the heat from the engine, since this is the "anyway" or wasted energy which heats the water in this case. Most of the time your hot water is ready when you arrive at the destination, plus you save on energy/propane.
