Water heater question

The argument against the drain valve is that it has to be removed to flush out the crud that collects inside the heater.
Of course, the crud does not have to be flushed out but the heater works better. Same as the water heater in the stick and bricks house.

On Edit: No answer is the only answer to rudeness.

Worse case scenario you could hit Harbor Freight and buy a large socket and extension. Then take an old hose and cut it 2 feet long. Keep both in your "tools" storage of your trailer. It makes draining and cleaning an RV water heater pretty darn quick and painless.

Thats assuming the Atwood wont work for you.

Do you struggle to thread the anode rod into the heater? I could see it being unpleasant if you had arthritis or some other issue to decrease dexterity.

I love my propane heater. My campground electric is $.24 KWH $$$$$$$ Gas is cheaper. Power goes out during a storm I got hot water. Wet thru hurricane Charlie in 05 for 10 days with no electricty. If you don't want a anode your probably gonna pay more $$ for an Atwood.

It sounds to me like you're basically looking for a small non-RV electric water heater. Most do have anode rods, however, but not attached to the drain plug. All I've seen have a hand valve for draining. They're radily available in various voltages and wattages. (Do bear in mind that a 120V 1.5 kW heater is not going to heat water super quickly.)

Per your no anode rod requirement you are looking for an Atwood (now Dometic) as they have an aluminum tank and no anode rod. Link

Unfortunately all the Atwood water heaters are also propane fired. As suggested above about the only thing you could do is install an Atwood and just not hook up to Propane.

You might try searching the Dometic site for non RV water heaters to see if they have anything you could use. But what you find may not fit in the standard water heater sized opening.

Atwood water heaters don't have Anode rods. They have a plastic plug. Just don't use the gas part.

You can jsut remove the anode rod, I don't know why but you can. You can also pull the drain plug and install an extension and a drain valve. Almost any water heater could be modified to meet you requirements.

You will probably NOT find one without an anode. Remove it and install a plug.
