Does anyone have a generator that runs their triangle tube boiler? Looking to buy one after our recent power outage. Type and brand. Thanks in advance

    Best to have a generator properly sized to match the electrical load you want . I have a Kohler generator that works fine serving an entire house.
    You can use a portable generator as well.

    I heard that triangle tubes did not run on certain generators, I was hoping someone that has a triangle tube has a set up that they could share.

    Never heard that one. I have had them on different generators.

    I will be following this thread closely to see where it goes.

    Any of the better modern small investor generators should be able to power the Triangle Tube. Get one which advertises low total harmonic distortion -- the better ones do. I like Honda, but Ryobi is perfectly good too.

    Be sure to add up the loads you expect to plug into it, and make sure that the generator rating is adequate -- don't overload it.

    Also be sure to figure out a safe way to connect it to whatever you are using it for.

    And it may seem obvious, but it warrants saying: the generator should sit OUTSIDE the house, not in the basement.

    Keep the generator away from all windows and any air intakes & exhausts.


    Also, Jamie means INVERTER generators, not "investor". Autocorrect strikes again!

    It is not only Triagle Tube that can have problems with "Dirty voltage" if Your Sine wave is clean that is half the battle..
    Viessmann does not allow for off grid systems.We would install a good UPS between the generator and the boiler and never had any issues. :)

    That is a good ides. A good UPS.

    That reminds me of a girl in High School.. We used to call her Federal Express. When she came to a party, She Absolutely, Positively, had to stay there overnight.

    After you make that expensive repair and you still have the same problem, What will you check next?

    Um... sort of. The UPS should help with cleaning up the power -- but not entirely, and it would be happier fed cleaner power to begin with. It's not a big expense, so don't cheap out on it.

    I suggest we identify the problem before you start throwing money at it.
    I think the rumored Triangle Tube - Generator problem you heard of is more likely to be caused by neutral and ground not being bonded in the generator. Most portable generators are not bonded. Grid power and permanently installed home stand by generators are bonded. Easy enough to bond a portable generator. But people forget this step.
    What else would you like to power in an outage? Do you have a well?
    Sizing the generator is critical. Too small, and voltage and Hertz will drop every time a load (sump pump, fridge, well) kick on. Too big, and you make many trips to the gas station. Starting amps are much higher than running amps for motors.
    Generators are loud. Some are really LOUD. This can get annoying after a while, to you and your neighbors.
    A UPS is probably not necessary.
    If you could give us some more details of your situation, we can make some suggestions. What kind of circulation pumps are on your heating system?

    Whats wrong with keeping my gas generator in the basement?  This way I stay warm when I have to refill with the gas cans I keep next to the gas water heater!!!!
    Ha ha ha.  JUST KIDDING EVERYONE but I have seen this firsthand... No Common sense.  Mad 🐕 Dog

    I remember vaguely during training for the Munchkin boiler that there was a problem with a sine wave harmonics that interfered with the Munchkin's performance and the solution was a line conditioner.

    When choosing a generator, choose one with the lowest THD (Total Harmonic Distortion) of the sine wave.
    If the manufacturer doesn't list it, choose another manufacturer that does. I chose a generator that advertised a THD of less than 5%. The power company's THD is about 2-2 1/2 %.

    My home has a Triangle Tube Instinct 155 Combi Mod-Con boiler. I also have an 8000w Generac portable standby generator. They have played well together many times. The generator is connected via a proper transfer switch.
