RV On-Demand Water Heaters

Atwood RV On-Demand Water Heater

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.

Even more Benefits
    ▪    No Recovery Time - There is no tank to run out of hot water so you can shower all day if you want.
    ▪    Energy Efficient - only heats water when you need it..
    ▪    Saves weight - eliminates up to 150 lbs. of dead water weight.
    ▪    Fits rough opening of all other brands of water heaters.
    ▪    Flanges on both sides to fit 12.5" to 16" and adapter plate for 10 gal. openings (16" high)
    ▪    No Anode Needed - No tank means you never have to worry about corrosion eating away at the tank.
    ▪    No By-Pass Valve Needed - No storage tank to by-pass when winterizing the unit.
