• OT but useful; Reset Button on Water Heater

    It just stopped working one day. I called in a heating engineer; he took
    two minutes to get it working again, and just charged me his minimum
    call-out fee. He said it must have just overheated, and that if it
    happened again I'd need a new unit. That was a couple of weeks ago, and
    it's working fine, used probably ten or so times daily ever since.
    I then googled around and found out the heater has a "reset button"
    inside it.

    Well you evidently got a decent plumber this time around. Keep his name and number.

    Ed,

    It strikes me as highly likely that most modern types of heaters
    have the same.

    Here in Europe they are mandated. Depending on the apparatus some will
    reset by themselves, some need user intervention, and others are
    single-use..

    Be glad that your heater could be reset, as over-temperature protections triggering normally means that something went quite wrong - especially in
    the case of a Water heater (boiler).

    Observe and learn; and don't get scammed by unscrupulous plumbers!

    I'm not sure if you are referring to the "heating engineer" there, but he
    could have made the situation look way more serious, wasting his time
    fiddeling around doing nothing, and charged you a lot more money than he
    did...

    Also, he would be taking quite a large gamble thinking you would call him to install a new water heater (and not try to find the cheapest one to do it)

    If I wanted to be unscrupulous I would change something in there to get it
    to fail in a few months and than charge you for a costly fix, only to have
    it fail a few months later - again needing a costly fix - and only after
    having squeezed you for a number of times "reluctantly" have told you you
    would need to replace it.

    IOW, you have little to go on to distrust the guy.

    Also, he would have been a rather stupid unscrupulous plumber to forget that almost everyone can google like you did.

    if it happened again I'd need a new unit.

    You could worse than to contact him and ask him why.

    He was recommended by a locally living friend (here in Europe) who told
    me he'd installed a complete heating system in his house a year ago; and
    he's a nice guy.
    He turned up on time, had an intelligent, outgoing personality, engaged socially and easily; so I let him in.

    There aren't enough innards to that box of tricks for him to have
    sabotaged. I did notice that he'd switched the dial down from hot to
    eco, so I phoned him and asked if it was ok to switch it back to hot. He
    said yes, so I did.

    Than I have no idea what made you post "Observe and learn; and don't get scammed by unscrupulous plumbers!"

    ....ahhhh... You just wanted to make us aware of that reset button, and
    where not trying to lay suspicion on that heating engineer.

    In that case, my water heater came with a manual, and it described how to
    reset it (selecting the right modus and press the button for a few seconds).
    I had to use it a few times in over a decade (the "booting" got stuck half way).

    Your own "lets google the device" approach also works. :-)

    At my previous House, I installed a Hydro-Thermal (or some-such) Hot
    Water System. In theory, as long as the outside temperature was above
    -10C, the Hot water system could produce Hot water by using the outside temperature to "boil" a fluid (in the panels around the tank) turning it
    into Gas, Then a compressor was used to convert that Gas back into a
    liquid and the energy gained was used to heat the water.

    But, it seemed to me, if the compressor started up at, say, midnight
    when the outside Temp might have been only 0C, the system would use a
    LOT of energy getting the water back up to 50C or so, costing me more
    than I might have otherwise saved.

    So I plugged in one of those Time-operated Power Switching devices so
    there was only Power available between 6:00a.m. and 6:00p.m. On the odd occasion, the system must have been heating the water at 6:00p.m. when
    the Power cut off so that caused the Circuit breaker to trip meaning the
    power to the Hot Water system was cut off.

    Being on my own, the 300ltr of hot water did me for several days but, eventually, I'd notice the Hot Water wasn't so Hot .... so I'd know I
    needed to re-set the Circuit breaker.

    I'll see your off-topic and raise you.

    I have a Philips DVDR with hard drive (and digital TV tuning) that I had
    to get when tv in the US went digital. I think that was 15 years ago
    and I used it about 5 hours a day either to record or play or both at
    the same time almost every day, until it broke almost a year ago. (All
    that time the HDD was spinning plus hours it was on but not being used.)

    Finally it totally broke.

    I bought an identical one on Ebay and when I plugged that in with all
    its cables, I unplugged the first one. I opened it up, thought it was
    the power supply since nothing lit up. Didn't use a meter but it
    "looked" fine. Looked around, found a short little black rubber
    cylinder 1 to 2mm in diameter and 3-4mm high. Like it was Wt Paint sign
    I coudln't resist pushing it down, and everything came to life.

    I still haven't connected it to a tv, but all the buttons that make
    changes on the display seem to work.

    IOW a reset button like on your WH.

    Wish I'd found it before buying the replacmeent. I wonder how many
    other electonic devices have them inside. On ngs, Carlos, from Spain,
    says he's seen them, or maybe read about them.

    It strikes me as highly likely that most modern types of heaters have
    the same.

    I have a central water heater, and I notice that the water temp varies.
    from not too hot for me even when not mixed with cold, to too hot when
    not mixed. I don't think it's seasonal and it shoudlnt' be since most

    Hello Americano. (:-
    I've never heard the expression "at-the-sink" used; and I don't think

    It's the same for my bathroom shower. A heating box, pipe in, pipe out;

    I just made it up, and now that you mention it, I don't think the ones

    that's what I have. There's no storage tank involved.
    It's the same for my bathroom shower. A heating box, pipe in, pipe out;
    and the water goes in from the mains supply.

    So you are talking about what I should have said. Fairly common here.
    I otoh have to wait so long for hot water, my hands have usually been
    washed already. I thought about putting in the other kind but it meant
    running electricity in addtion to the plumbing. For a bath or shower,
    waiting is worth it, but at the sink it's annoying . I insulated the
    basement pipes when I first got here, but there is more pipe going up to
    the 2nd floor and when you live alone and only use the bathroom sink no
    more often than 4 hours and usually more, the water cools off anyhow.

    I have a Philips DVDR with hard drive (and digital TV tuning) that I had
    to get when tv in the US went digital. I think that was 15 years ago
    and I used it about 5 hours a day either to record or play or both at
    the same time almost every day, until it broke almost a year ago. (All
    that time the HDD was spinning plus hours it was on but not being used.)

    Finally it totally broke.

    I bought an identical one on Ebay and when I plugged that in with all
    its cables, I unplugged the first one. I opened it up, thought it was
    the power supply since nothing lit up. Didn't use a meter but it
    "looked" fine. Looked around, found a short little black rubber
    cylinder 1 to 2mm in diameter and 3-4mm high. Like it was Wt Paint sign
    I coudln't resist pushing it down, and everything came to life.

    I still haven't connected it to a tv, but all the buttons that make
    changes on the display seem to work.

    IOW a reset button like on your WH.

    Wish I'd found it before buying the replacmeent. I wonder how many
    other electonic devices have them inside. On ngs, Carlos, from Spain,
    says he's seen them, or maybe read about them.

    It strikes me as highly likely that most modern types of heaters have
    the same.

    I always associate "reset button" with "reboot"; ie there's a microchip controller involved. I can see how a VCR would have one, but a

    It just stopped working one day. I called in a heating engineer; he took >>> two minutes to get it working again, and just charged me his minimum
    call-out fee. He said it must have just overheated, and that if it
    happened again I'd need a new unit. That was a couple of weeks ago, and
    it's working fine, used probably ten or so times daily ever since.
    I then googled around and found out the heater has a "reset button"

    Good point. But it's not the button but that they keep it a secret. I
    forgot to mention that the owners manual said nothing about this button,
    and the service manual for something similar had nothing about it
    either. It's like it's designed that it appears to break at some time,
    and when you bring it in for repair, he waits until you leave, pushes
    one button, and charges like it took time.

    I've seen "reset button" used to refer to a thermal circuit breaker. I
    remember one on the water pump my grandparents used to have when they
    lived on a farm.

    Probably called a "demand heater". My grandparents had one in the
    1930's - it was over the sink - the trade name was "Geyser". It ran off
    mains gas, the electricity supply was never man enough to drive such a
    thing.

    There are now electrical equivalents but they need dedicated wiring
    because they take up to 20kW.

    You must be talking about an at-the-sink water heater, right?

    I have a central water heater, and I notice that the water temp varies.
    from not too hot for me even when not mixed with cold, to too hot when
    not mixed. I don't think it's seasonal and it shoudlnt' be since most
    of the water sits in the large tank for hours before it's used. Because
    I live alone, unless I take a bath, it's days before much is used.

    I don't think it's me, either.


    It depends on the type of water heater, as to the expected behavior.

    And the buildup of lime scale, affects some design details more than others.

    But overall, in a perfect world, the heaters are thermostatically
    controlled. How the water distributes itself in the tank (convection),
    is a mystery. I have no idea, how long it takes uneven heating,
    to "even out". All sorts of things we design, have "stratification"
    issues, which is why I can't really guess as to whether your
    observation is influenced by stratification.

    Maxwells Demon, likely taught the water heater how to sing.

    https://en.wikipedia.org/wiki/Maxwell's_demon

    "The second law of thermodynamics ensures (through statistical probability)
    that two bodies of different temperature, when brought into contact with
    each other and isolated from the rest of the Universe, will evolve to a
    thermodynamic equilibrium in which both bodies have approximately the
    same temperature.[6]"

    We rely on these laws, to have a good shower.

    If it had SMART, you could pull the drive and cable it
    up to the PC and check the SMART power-on-hours and see
    just how long it's been spinning.

    Spinning does not have to be bad for a drive.

    Back in the day, the drives had ball bearings, and
    the drive would get "noisy" as a metric for how worn
    it was.

    The drives today use FDB motors, and those have
    been "relatively perfected". Initially, there
    were some problems with the seal and oil loss,
    but that seems to be fixed. An FDB motor should
    be able to run for a very long time.

    The second issue is flying height of the heads.
    As long as the tolerances aren't too tight,
    there should not be any platter surface degradation.
    This could be why my "heroic" 500GB drive has
    lasted so long. Decent flying height. FDB motor.

    Some very recent drives, they have added back
    the "jiggler" behavior, to prevent the heads from
    staying over one track for any period of time.
    They have had to do that in the past, then removed
    it, and it's been added back for the biggest drives.
    The flying height on the highest capacity drives
    is quite low now. While the patents say "3nm",
    I assume that's bullshit. The surface finish of the
    platter, appears to have a roughness of 2nm or so.
    And if the head touches, it does not touch metal,
    as there is a polymer coat over the polished disc
    which is the first point of contact.

    You know, some of the older drives did us a disservice.
    I opened up a worn out 250GB drive, and it had NO LANDING RAMP.
    The bloody heads were found resting on the platter next
    to the hub. Apparently the platters are laser-patterned
    near the hub, to cure the stiction problem. I did not
    know the idiots were still using stiction designs,
    in the 250GB era. I am now concerned that when I
    open up one of those 0.8" high Seagate 500GB that
    gave me so much trouble, I will find the same practice.
    For such drives, it is better for them to keep spinning!

    There was an AV webpage forum that discussed it. I haven't read the
    stuff for about 14 years but iirc the one included is 50gigs or
    sometthing, and people on the forum posted instructions on how to
    replace and format a new one if the old one failed. I think it would
    take up to 100 Gig. But I'm bad remembering numbers and I coudl be way
    off.

    Ah, I found one of the pages: https://www.avsforum.com/threads/philips-dvdr3575h-37-160g-hdd-dvd-recorder-w-atsc-tuner.830253/page-174
    It came with 160Gigs and I think can take 500Gigs I was closer than I
    thought I was. Anything that big probably does have SMART, but I'm not
    going to take the drive out just to check the hours!

    If I take the cover off again, I can see what make drive it has.

    If it had SMART, you could pull the drive and cable it
    up to the PC and check the SMART power-on-hours and see
    just how long it's been spinning.

    Spinning does not have to be bad for a drive.

    were some problems with the seal and oil loss,
    but that seems to be fixed. An FDB motor should
    be able to run for a very long time.

    The replacement DVDR I bougth was the same model and probably as old,
    though I don't know how much it was used. it was very clean, but those
    ebay people seem to be able to clean things up really well.

    I'm using it right now, and I expect the next problem won't be the HDD,
    but some hidden timer that will make it totally break and only
    repairable by pushing that button.

    The second issue is flying height of the heads.
