    Some folks on here will have local experience. 20 years is a pretty good run for any indirect in any area.

    You might want to think about stone lined. Really depends on water condition.

    Hi, I agree with @Zman that 20 years isn't bad. If you can change anodes as needed, a glass lined tank can last a very long time as long as pressure is controlled. I've gotten fifty years from glass lined tanks.

    Yours, Larry

    Do indirect's have an anode?

    Some do, some don't. Most stainless models do not.

    I would think glass lined indirect water heaters would have a anode rod.
    SS indirect water heaters can be destroyed by high clordies plus there are different grades of stainless steel.
    Stone lined indirect water heare from Vaugh is a good unit. Vaughn also builds a plastic indirect water heater called their Featherweight.

    Both of my original Buderus tanks went over 20 years ... one made it to 25. The new thermoglass are about 1/2 the weight and I was reading about failures -- replaced both w/ stainless. No anode in B stainless tank .. yes in the thermoglass
