Anode rod

[vandave]

Looking at a new class A and when they showed where the water heater door was I noticed there was not a place for an anod rod are they no longer needed?

Whether a water heater needs an anode rod depends on the materials used in its construction. As noted above, different manufacturers use different materials.

Some new rigs do not have a tank, but are continuous demand water heater.
make and model of rig you are looking at.

There is always a place for an anode rod.....they go in the drain hole.

But as noted Atwood doesn't require one even though aftermarket has them for sell.

Anode rod is a sacrificial rod of magnesium (Suburban OEM Rod) or aluminum (Suburban Optional Rod). Suburban requires them because of STEEL Tank that is glass-lined.
Atwood doesn't require them because of Aluminum Tank clad with zinc alloy

Suburban water heaters require an anode rod, Atwood water heaters do not.
