Not sure where you do your shopping but a NG conventional vent is 50% more than an electric tank. And electric water heaters have anode rods just like gas heaters.engineered wrote: ↑ A natural vent NG tank is about the same price as an electric tank and is the same or less maintenance (no anode to ever change). You also have hot water when the power is out.

You're right, electric is cheaper, between $300 on lower end and $100 on higher end. I meant to say electrode, not anode.
It's still going to be cheaper to run NG if you use lots of hot water.

BS ... you meant to say and did say anode.engineered wrote: ↑ You're right, electric is cheaper, between $300 on lower end and $100 on higher end. I meant to say electrode, not anode.
$699 electric https://www.homedepot.ca/en/home/p.perf ... 39811.html
$799 gas https://www.homedepot.ca/en/home/p.rhee ... 92346.html

You're in a hole already so let's make it deeper.engineered wrote: ↑ Please let me know where you get your drugs that give you psychic powers to read my mind. Seems useful.

As a FYI, not all natural gas water heaters do either.thriftshopper wrote: ↑ As an FYI, not all electric heaters have an anode. My new one doesn't (but it does cost more than a basic gas tank).

Seems you are the one in a dark hole. I never said NG tanks have an electrode.
Presumably all non-ferrous tanks (fibreglass) do not require anodes. Is that what you have?thriftshopper wrote: ↑ As an FYI, not all electric heaters have an anode. My new one doesn't (but it does cost more than a basic gas tank).

The term used is polybutene. It's softer than FG by the looks of it.engineered wrote: ↑ Presumably all non-ferrous tanks (fibreglass) do not require anodes. Is that what you have?

The monthly draining is recommended where water (presumably well or aquifer) is hard presumably due to the stuff precipitating and having nothing to stick to. I'll drain mine early next year to see what accumulated (over here, it looks like sediment as the water comes from a Pacific rain-filled reservoir)TomLafinsky wrote: ↑ As far as I know only the Rheem Marathon electric water tanks do not have a rod because the tank is a type of plastic. But you still need to drain a gallon per month if I'm not mistaken. Any other tank models without an anode rod?

I'm almost tempted to find an old bronze/brass tank, update the design and see how much it'd cost to get it made in China or India and shipped to/distributed in North America. The technology (ain't exactly high-tech) is there to make long-lasting heaters but there is an industrial conspiracy to make you buy a new tank every decade or so.TomLafinsky wrote: ↑ Interesting. Thanks for the info. I wish we would build things to last. I did look at the Marathon but it was twice the cost. So instead I decided to go with the traditional. I figured I can always change my mind the next time I'll need a new tank.
Well, here's a question: If the water is primarily heated by the heat pump, does the anode/tank corrode as fast, or is corrosion a function of the electric element and/or flame heating?Too bad Rheem doesn't make the Hybrid High Efficiency with the tank of the Marathon. That would be a winning combination. Btw your heating elements are titanium and they sell for US$50/each at HD USA.
