How On-Demand Works
  1. Hot water tap is turned on
  2. Flow sensor detects flow of cold water coming in
  3. The burner is automatically ignited
  4. Water is instantly heated up as it circulates through the heat exchanger and out to the tap
Endless Hot Water
No more RV Showers. Since Atwood's on-demand water heater instantly heats water, it can supply a constant stream of hot water that is limited only by the fresh water supply.
Weight Savings
An on-demand water heater does not use a tank, thus eliminates up to 115 pounds of dead water weight
Energy Efficient
  • Atwood On-demand water heaters only heat water when it is needed. No wasted energy.
  • Traditional tank water heaters must turn on periodically to maintain the stored hot water temperature.
Cold Weather Performance
  • High output burners deliver hotter water more days of the year.
  • Just because it is cold outside doesn't mean you get a cold shower.
Simple Operation, Just like home
  1. Turn on Hot water
  2. Mix in Cold to reach desired temperature

Modulation Valve

  • A flow controlled valve adjusts the burner input from 16,000 - 50,000 BTUs based on water flow rate (The slower the flow, the less heat that is needed). This provides for optimal operating efficiency.
  • Brand X will have 2 settings only at 27,000 and 34,000 BTUs. This results in not enough power on cold days and wasted energy on hot days.
One Size Fits All
Wide side flanges and an adapter plate allow Atwood's On-Demand to easily fit the rough opening for all other brands of RV water heaters
