What is a reverse indirect? I just googled it and came up empty handed.

    indirects

    is everybody still installing indirect water heaters... how come there are no anode rods in them... and how come everyone that i see doesn't at least have di-electric unions on the hot and cold line... i guess that why they are short live or is it just cheap material... i like my aquaboosters... anyway i just felt like saying something. have a good day everybody i have to go back to work...

    Hey!

    I just put Dialectrics on mine cause my installer had these long brass T's and I wanted to be different.

    Hey Steve

    you should try installing quality indirects. We do them all the time and only have to replace the lower quality units.

    We use Super-Sote with great results. Stainless steel tank with no anode or Die-electrci. We gone through this before and I don't see a need for them.

    I quit installing indirects...

    Now I install reverse indirects.

    Even when I was installing indirects, I didn't HAVE to use dielectric unions because I was using stainless steel tanks...

    And even if I DID have to install dielectric unions, I wouldn't, and if you have ever had an occasion to look inside of one that has been in service for even just a few years, you wouldn't use them either!

    I also don't use unions because the consumer views them as "velcro" and it invites trouble. If you don't know how to solder or thread pipe, maybe you shouldn't be messing with it. I treat dis-similar metal mixes with a neutral component called brass fitting or valve. Works MUCH better than a dielectric union.

    Aren't you from Colorado?

    Turbomax, Ergomax...

    You run the boiler water through the tank and the potable through the coil, hence reverse indirect.

    99% efficient heat exchanger that keeps a condensing boiler in the condensing mode even when it's making DHW.

    I'll take two!

    SOLD .. I like that idea is there a dealer in Utah or maybe I can talk someone to be an authorized dealer.

    Dielectrics.

    I know the deal with them. Can't figure out why there are not more brass options. Like a 6" Female to Male adapter. Anyhow, I figure there are three Unions on a TRV so whats two more. Im toying with a Female union mounted on a 6" brass nipple.

    Brass unions

    I usually use brass FPT x sweat unions on my water heater, and indirect installs.

    Re: Brass or dialtectric, we switched to brass appx 15 yrs ago,

    tired of leaks on the lousy dialectrics. We usually use a brass nipple and tee w/ drain then a MIPxswt union or just sweat union off that then copper on the indirects.
    Mark, ?? Is the Turbomax a steel tank w/ glass lined, that's what I seem to remember. Just wondering. Also what do you see in a stainless indirect after a few years that bothers you? Tim

    T-Max tank is mild steel, no glass lining.

    What irritates me most about the majority of the indirects on the market is their poor performance. 180 degrees F to generate 140 degrees F potable water temperatures, and an extended amount of time to get'er done causes the hair to stand up on the back of my neck.

    I have had numerous cases, even with the tank within a tank design that were slow in satisfying a 140 degree set point. With the RI, you only need to generate water 5 to 10 degrees hotter than your target potable temp, and when it locks into a continuous load, it LOCKS IN. The boiler is not cycling on the high limit due to the inefficiency in heat transfer of the dinky heat exchanger in most indirects. With the RI, when it gets a call for DHW, It's on and stays on producing useable energy.

    You'd have to see it in operation to believe it. Once you try it, you won't go back to a conventional indirect.

    Even had

    An inspector (who is now retired) go on a kick with installing them on HW boilers! Talk about leaks!. I despise dielectrics!
