    Default Water Heater Dilemma with a Tankless Question

    Bear with me as I try to take you through my scenario. I am currently on my third tanked water heater in 44 months!! Come to find out, the water softener I have seems to eat up the anode rod really fast and this was confirmed by independent studies that were sent to me by A.O. Smith.

    My family definitely likes the soft water but we can't afford to keep paying $300 in labor to have a new heater installed, plus the $300 for the new heater when the warranty runs out!!

    It seems to be that a tankless system would be the way to go whenver this heater, we just had put in, bites the dust.

    I've done some research and see that there are 2 options, gas or electric. Of course, there are pros and cons with both systems. Correct me if I'm wrong, but the gas systems are more expensive to buy and to install, but save you more in efficiency than the electric systems.

    My question is, which option would benefit me over the long haul, assuming I am in a house that I plan to be in for at least 10-12 more years?

    Thanks for your expertise, time, and patience.

    Jack

    Got a link that you can share? There are a few folks in the softener forum that swear up and down that a softener doesn't contribute to corrosion.

    My gas water lasted 10 years on my softened water. When it came time to replace, a rental made the most sense. Free install and free replacement.

    Resizing the gas line and testing the gas supply along with the high cost of a tankless killed that option.

    LL,

    Got to run out the door, but when I get back, I will post the pdf links here. Not sure what you mean by rental, but I am curious and open to hear about all my options. Be back later this afternoon/early evening.

    Thanks LL,

    Jack

    The rental agency takes care of installation and all servicing through a network of contractors. The local contractor affiliated with the rental agency is who sold me my original water heater 13 years ago and was willing to sell me another one. After doing the math on install cost, possible out-of-pocket expenses on warranty work, and replacement cost, the rental worked out cheaper.

    When you get a warranty replacement, is there any out-of-pocket expenses? With the rental, I don't incur any cost to get warranty work done.

    I have to pay for all the labor.

    Those only mention faster deterioration of the anode, not accelerated corrosion of the tank. Now granted, if all of the anode is consumed, the protection from it ceases but as long as you replace the anode, the protection should last. I don't know what the timeline was for your 3 tanks in 44 months but if equally divided, 14 months per tank is implausible for complete anode consumption.

    Here is a link to info about corrosion and soft water.

    http://www.ndhealth.gov/wq/gw/pubs/mineral.htm

    Here is a link to Environmental Engineering by Joseph A. Salvato
    The info in the report above comes from this book on page 312 under the heading of “Hardness” and goes to page 313.

    http://books.google.com/books?id=dBz...rosive&f=false


    Here is a CDC site and it discusses corrosion of low hardness water under the heading of
    “Water properties influencing corrosion”

    Water has the nickname of universal solvent for a reason...while it may take millenia, few things are immune to its long-term effects and some will succumb much faster.
