RV On-Demand Water Heaters
The Atwood On-Demand Water Heater Ensures There Will Always Be Enough Hot Water
Hot water, like the air we breathe, is easy to take for granted, that is, until you don’t have it. Especially in those moments in the shower. When, after a few minutes the water stream wimps out and morphs from cozy and warm to painful and icy. This is especially true in mobile situation where space and efficiency makes for smaller capacity water heaters.
Hot Water When and Where You Need It
With an Atwood on-demand water heater in your RV, trailer, or 5th wheel you will have hot water on demand in unlimited supply. High output burners instantly heat your water. Simply turn on the hot water faucet like you would normally, but rather than storing it in a tank the water passes through the heat exchanger of the tankless water heater heating it to your specifications. Hot water comes out of your faucet. Of course water is hot as it leaves the heat exchanger but standing water in the lines must be voided before hot water is felt at the tap on the next use.
How it Works
1. A hot water tap is turned on.
2. Cold water enters the heater.
3. A water flow sensor detects that water is flowing.
4. The microprocessor based circuit board automatically ignites the burner.
6. Water Circulates through the Heat Exchanger.
7. The water is instantly heated to the set temperature.
8. When the tap is turned off, the unit shuts down.
9. All on-demand water heaters operate only on LP gas.
