Whole house generator

   / Whole house generator #31  
We purchased a(LP whole house) 17kw generac (air cooled)two years and could not be happier.From what my generac dealer/installer told me the key to longevity of the air cooled engine was to change the oil after the generator has run for a period of time(say 2-3 days).He also stated to use full syn.oil 5w-30 which I do.coobie

Oh and by the way I was suprised to learn that those propane generators burn lots of fuel, I can't remember exacts but it was at least a gallon and hour FYI
I have to disagree with this statement.Our 17kw generac whole house generator (LP )only used 7% in 3 day run time(24 hours per day)under 30-50 % load.

7% of what?

I'm curious as to why you would want a 20KW generator. It seems like a huge investment for the number of hours that you would actually use it. And when you do use it, it sucks down a lot of expensive fuel.

Where I'm at, a 5000 watt generator is plenty to run essentials until the power is restored.

Travel during the winter so wanted a unit that would start automatically & be able to handle the essentials - heat, water, sump pumps, appliances, etc.
Have lived through several outages in differing locals of 2 weeks or more (at minus 30 degrees during the ice storm of 99).
20KW actually isn't enough to run my whole household due to the draw of my geothermal unit so only have the backup electric heat hooked up (good enough to keep the house above freezing should we be away during the outage).
Was going to buy a 14KW unit, but my builder got the 20KW for same price. Since we were building the extra cost of installing the unit wasn't that great.
Also use propane for the stove & probably a future propane fireplace when/if I finish the basement.

Sorry 7 % gal. of propane.We have a 500 gal.tank.According to the gauge on the tank we used 7% of propane for 3 days running the gen. 24 hours a day.coobie

I'm looking to install a whole house auto start up unit before winter myself. I'm trying to decide between 14kw and 17kw being run on NG. It will be either Kohler or Generac. Any pro's or cons of one brand over the other?

So 35 gallons over 72 hours - or JUST under 1/2 gallon per hour. Not bad...

Hm, according to generac web site, this gen set at 50% use = consumes 1.6 gal/hr and 2.57 g/h at full use. you must have just been ideling hehe

We had a power outage for 3 full days recently. I thought I was protected with an 8kw Dyna (Winco) genset. I was, sorta. However, if you happen to have a number of motors starting up simultaneously, the instantaneous current draw can do some bad things. I lost my expensive dehumidifier and my oil burner and refrigerator sounded a bit weird at times. Most likely due to low voltage at that time. I felt 8kw was ample, but keeping that genset would necessitate my taking some things like our freezer, dehumdifier, and a couple other things off to make sure I don't have a brown voltage situation again. It is also why I'm considering a 14kw unit now. It's a commercial diesel, very well built, and if I project another 10 years ahead with it, it will still have low hours and be worth nearly what it's worth now. It does not seem like a bad investment for me now, all things considered. Still, 3600 bucks ain't cheap, but as I said, it's not gonna lose much value and no function with whatever in the next decade.

I believe in my first post I said between 30-50 percent most of the run time.Just the wife and I at home.I was not there most of the time as I am a electric lineman and was putting the power on for 7 plus days(ice storm) for all of the good souls who did not have a generator.Wife at home by herself = little load used.I guess if you don,t believe that I don,t know what to tell ya.coobie
