OT- Hot Water Tank vs. Tankless -OT

    I installed a chilipepper pump over 15 years ago when we had a tankless heater installed.

    The design and control mechanism have changed of course.  

    It worked well but when it ran it would vibrate and sound louder than a shopvac! Not sure if current one has improved. Eventually had to remove it because the one-way valve integrated with the unit ceased to function, i.e. allowing hot and cold water to mix. Took me months to realise why the hot water temp would fluctuate at random.  Meant to install a one-way valve into the circuit to fix the problem but never gotten around to it.

    If you search for "instant hot water pump" on Amazon, there are all kinds of options.

    I don't think it has been mentioned. If you have hard water or a lot of minerals you may have problems with a tankless.  I did some basic research awhile ago and came across that concern.
    This is true ... the heat exchange tube will scale fast
    that is a scare for me to trying to switch from electric to gas.  we have very hard water here. 
    Look, not like that won't create issues for the hot water tank as well, you will get scale on the bottom (inside) the tank ... unfortunately with most scale around 40'C (around 110F) is about the worst place to operate (gypsum especially).  The thing with the tankless though, there is a fairly doable procedure to clean the scale, you have a small heating tube to clean ... the water tank on the other hand ... good luck.

    Not that it's apples to apples...we have no access to gas, but we replace our electric water heater a couple years ago.  Water heater , $400, plumber, $250 cash.  Your plumber seems expensive...

    If that was for me, as far as expensive, I get it. I watched numerous videos on Utube and one was from IL, 2 years ago, from a plumbing company that for the same Navian 240a was 3600. I had an estimate in the meantime, different tankless, 4k. So, anyway I do know that I might get it cheaper somewhere elsewhere but I'm on limited time and given what I've seen I'm comfortable. God love you DIY guys and if you're certified for warranty purposes and can do it for less in Cumming, GA, DM me.

    Love my tankless, plus it freed up a bunch of space in the middle of my basement.

    When my builder grade 40 gallon died a few years back, I bought two quick recovery 50 gallon tanks. I plumbed them so that I can run each independently, or in series (used most of the time). I have five in the family, and a few family members that take incredibly long showers. The water never runs out. In fact you never have to adjust the heat on the shower. I’m not sure i will consider tankless in the future based on this experience. Gas is cheap (here in Utah). Tankless technology eventually pays for itself, but much like solar, the gravy years are when the product is near replacement.
