Default Kohler 20RESCL

Does anyone have first-had knowledge of this current model Kohler for whole house backup? It is being recommended by a couple of local installers.

Thanks,

Dave Pratt

One of those 20kw 3600 RPM resi units I’ve been told (by a dealer) is pushing the engine a bit much and consumes oil. I don’t remember the exact model, and it was from years ago so they may have updated the design since then. If you’re looking at getting one I can make a call tomorrow and find out for sure which model was the problem one.

It is a big air cooled v-twin at 3600 RPM.

Kohler is a good brand, the only one that really supports their dealers. Make sure you are buying from a real dealer with real service ability.

While air cooled 3600 RPM have become the de facto standard for home standby, liquid cooled 1800 RPM are still worlds better. Adjusted for inflation they cost about the same as they ever did. (A lot more than air cooled)

So if it really needs to work when the chips are down, you know what to do.

I have so far found three in this category - Generac, Cummins, and Kohler. In my investigation thus far, the Kohler has the best reputation. This gets down to a judgment call - for an area that gets 1-3 outages per year, it is hard to justify the higher cost of the 1800 rpm unit - although I don't think anyone would argue that this is is the way to go if cost is not a factor.

Bill, I would appreciate any information you can get on this, I need all the help I can get.

Thanks to all who have replied. I'll try to make an informed decision.

Cummins or Kohler, stay away from the Generac and others that sell mystery engines.

Look for used Up scale stuff too.
Onans are nice.
Liquid cooled Kohlers with automotive based engines are good.

Onan is all but gone. The Cummins products of today share almost nothing with the good old Onan of yesteryear. Their air cooled products have been nothing but a thorn in my side. Although I have not seen one of the latest crop yet.

Not trying to pile on the argument but if somebody else is reading and on the fence.

20 years ago it was liquid cooled or nothing and there would not even have been a question about this.

If somebody needs a generator then I advise them to get a real generator. Especially 20 kw+.

That being said, Kohler does make their own engines, they are used in commercial applications as well and the 14 and 20 are hydraulic lifters unlike the others and seem far and away better engines to me, and I see a lot that are going the distance as prime power in my business.

Some, but not all.

Most of the utility engines are Chinese and compatible with most other clones for parts ( that's a good thing cheap easy to fix ).
