How many hours will a 7000 watt generator run....

2 250 watt heat lamp bulbs? 5.5-6 gallon gas tank. I am thinking 12 hours.

  • If you run any gas generator underneath or near your trailer (as pictured), the fuel supply is unlikely to expire before the occupants do.
  • you are asking about a 7000 w.My generac is 7500 and will use 3/4 a gal. per hour under full load.
    Is this what your are looking for?

    The best way, is to read the manufacture's spec. My Yamaha 2000 states 9 hours in the eco mode, and I think, I said I think as I did not locate my manual, it says 4 hours full load
  • I made an extended run tank for my 2000 using a marine gas tank from Wal Mart and some fittings. Aux tank is 6 gals and it will run the Honda at full load for a couple DAYS.

    My 2KW Honda EU2000i generator will run for around 7 hours with a pretty good load...

    If your 2KW model is a HONDA EU20001 they do sell an extended run tank. The EU2000i generator has its own built-in fuel pump so this will work with almost any extended fuel tank you might come up with...

    Just another thought perhaps...

  • I need it to run all night. It is at our schools farm and did not want to get up at 2 am to refuel. I have a 2500 and a 2000 but I would have to refuel.
  • Just as an off-topic factoid, my little 650 watt Honda will run a couple of 250 watt bulbs for around 5 hours using about one-half gallon of gas. You have to look for this genny used, however.

    500 watt is no real "load" for a 7Kw gen..

    Typically the run time is given for HALF LOAD which will be the size of your tank.. You will be less than half load so I would guess you can use the half load number..

    That is a awful big gen for that small load.. I would suggest finding a smaller gen that would match better and save on a lot of fuel.. A 2Kw gen would easily use 1/4 of the fuel..
