at the lengths some people will go to to "save money on heating".

Went to do a tune up for a new customer today......found this. 3" water heater flue runs downhill for about 10' to the connection you see.

Will be replacing the water heater with a side arm, fixing the flue and doing some minor repairs. The boiler itself seems to be in pretty good shape at least!

    I've heard of Magic Heat units before but this is the first time I've seen one in the wild!

    Must be magic to make the flue gases go down then back up like that lol

    Oh I have a hard-headed cheap customer with one on an oil burner flue pipe.
    “Heats the whole basement for 'free'”.
    I posted the pic before...
    I make him take it off and remove the wiring before annual pm.

    This is a diy job. He solved the ghost flow issue by installing zone valves on each circulator zone.
    Won’t pay to clean up any controls/wiring/piping.

    There was an error rendering this rich post.

    And all three circulators are vertical, no insulation, pipes corroded by flux not removed.........Hope he got a deal.

    Replacing the WH with a sidearm, somebody is going go be very disappointed with their 7 second showers before they run out of hot water

    @SlamDunk the antiques they have in that house are amazing, radios and cameras mostly, his hobby seems to be fixing old 1920s and 30s radios, house is filled.

    @GroundUp Why do you say that? an IDWH will make a hell of a lot more hot water than the 20 year old WH that is there....

    @delta T I say that because a sidearm has the BTU exchange of a BIC lighter. There was no mention of an indirect until now- at which point I am on the same page.

    @GroundUp I gotcha, yeah I meant an IDWH, in my neck of the woods, the two terms are interchangable. Are you talking about an everhot or similar heat exchanger?

    Funny how we all have slightly different terminology. I had a distributor get rather angry and upset with me when I tried to order a PRV (Which is what I call a Pressure Reducing Valve). He insisted that a PRV was and could only ever be a Pressure Relief Valve. He actually got so upset about it that he hung up on me :/ I thought I was being pretty nice about it....guess he was having a bad day Lol>

    Hi @GroundUp , Watts, who invented the temperature and pressure relief valve calls it a T&P relief valve or T&P. Your distributor must have been having a bad day, cuz he had it wrong. o:) Now for pressure relief only, they call it "water pressure relief valve", "safety relief valve" and "boiler pressure relief valve". It could get confusing!

    Yours, Larry

    That darn terminology! What I refer to as a sidearm, is literally a "side arm" HX on a tank style WH, basically a pair of tubes inside one another where boiler water runs between the inner and outer via a couple tees and domestic on the inner tube via reducers at the end. Most often used (here anyway) in outdoor boiler applications with constant circulation and create a thermosiphon to keep the tank hot with no additional circ. The output is very low however, so the picture I had in my head was just a 4ft long copper log hanging in place of a tank hoping for on-demand heating like a plate HX would provide.

    @GroundUp yeah I've seen a few of those, usually on old solar systems. We call them tube exchangers. Yeah, don't think my customer would be to happy with that lol!

    I find those stack robber's, tend to soot up modern Boilers. Too low a stack temp.
