Will this 22000-watt (LP)/195000-watt (NG) unit be sufficient for a 3800 sqft home house with well water and we utilize natural gas? Thank you Ella
Asked by: Ella
The size of the generator needed is dictated by the power requirements of all of the circuits and appliances you want to run rather than the square footage of the home. The power needed for many large items in the home such as air conditioners, water heaters, and other appliances varies widely. We recommend working with an authorized Generac dealer to determine the generator size that would best suit your needs.

22000-Watt (LP)/19500-Watt (NG) Air-Cooled Standby Generator with Wi-Fi and Whole House 200 Amp NEMA3 Transfer Switch is rated 4.8 out of 5 by 1499.

The motor seized on first test. Generac sent Company A to diagnose and Company A said it needed replacement. Three weeks later, I called Generac and was told that Company A lost their certification to work on Generac equipment and they emailed me a list of other local companies. I contacted Company B which promptly diagnosed the same problem and offered a quote to replace. Generac said Company B cannot do repair work, as they are only installers not repairers, and Generac would only send a motor not a new generator. Meanwhile I was invoiced $200 by Company B. Generac then sent an entirely new unit (?) to Company A (??), which apparently renewed their certification. Generac left me holding the bag for the $200 invoice from Company B, which was on the list they sent me. Numerous calls to customer service (nice people, but worthless) led me nowhere. Great machine if you have no problems -- horrible company if you have problems.

Rated 5 out of 5 by from Now I can review the product. My standby generator was installed about a week or so ago. The other night we had strong winds that blew some branches down, breaking power lines that supplied electricity to our city. About 20 seconds after our lights went out, I heard our generator crank-up & start. A few seconds later, everything came back on. My wife looked out the window & told me everything in the community was still dark." That's so cool!" Was all she said. About 3 hrs. later, I heard the generator slow down, then shut off & seamlessly everything stayed on. It was great to find out so soon after the installation that we had indeed made the right decision & a good investment by purchasing this product & this model. It was up & running before I could have reached a flashlight. It made less noise than our A/C unit & we've already had our community association reps. tell us how nice the unit looks.

Rated 5 out of 5 by from ABSOLUTELY AWESOME! I live way out in the sticks so when the power goes out, we are the last ones to get the power restored. I have the 22KW whole home system. This is the best investment I’ve ever made, by far! Our power goes out a few times a year and sometimes it’s out for 7 or more days. About 2 weeks ago, we were hit with high winds and thousands if people were without power, but NOT US! The outage lasted for 6 days and we never knew it was off in the first place. When the power goes out, it takes the generator 20 seconds to start up and it never shuts off until the power is restored. In those 6 days, it used 105 gallons of natural gas, but it was worth every single penny. If you’re thinking about buying one, just do it. I promise, you won’t regret it!!

Rated 5 out of 5 by from Piece of mind We just moved into a 15 year-old house with a sump pump and could not afford to have the electricity go out. I knew Generac's are excellent, in part because my 2 brothers and I have identical 5500 watt portable generators which have worked flawlessly for years, and in part because I have never seen a product with thousands of reviews be so uniformly recommended. In fact, the buyers actually requested I include the portable generator with the house as a condition of the sale. When we decided to protect the entire house because of the sump pump, we found a Generac preferred dealer nearby who gave us a fair price and exceptional service, and our extremely happy with our purchase. Thanks for engineering a fantastic product. Pete

Installation was quite a bit more than anticipated, but the electrician was at the house literally all day and we had to have a second company connect the propane. So I would plan on about $3k for professional install. It cost me a little more. It did include placement (more than 500 lbs, I really underestimated the size), supplying a concrete pad, in addition to all hardware. I purchased the mobilelink. First one was faulty and had to replace it, but second one works fine. Ironically, I'm in the middle of writing this review and lost power. Not sure why, but the generator kicked on just like it is supposed to. I use battery backups on all of my electronics so I would not have even known the power went off except for the UPS beeping at me. Love having this generator.

Rated 5 out of 5 by from Power outtage answer My house is all electric and for several years I've gotten by with a portable generator, but it couldn't power my entire house. The Generac Guardian 22kw is just the thing for whole house electric power. Installation took place over 5 days, pour the pad (over weekend to set) place generator & 250 gallon tank, then transfer switch install. Finally the battery was installed and unit started. My Heat Pump was turned on then; both heat & air, worked perfectly. Electric hot water tank operates normally under the generator power along with all my other appliances. Weekly 5 minute test run was then programmed; the generator started & stopped on time. Completely satisfied .

Rated 5 out of 5 by from Finally! I have been wanting a Generac automatic stand by generator since 2012 when we had a week long power outage during the hottest week of the year! The unit was just installed, and 5 days after installation we had a brief power outage and it started right up and powered the house exactly as it's supposed to. Now I can go on vacation and not worry about my basement flooding, or my beloved koi fish dying from lack of filtration and oxygen in the event of a power outage. I am also an otr truck driver, and now I don't have to worry about my wife and kids being with out power when I am gone.

Rated 5 out of 5 by from No longer dark I purchased this generator and had installed by Sentry in Birmingham. For 9 years, I have been using a Honda 2000 for power on a reagular basis about once every 6-8 weeks with power outages. Being one of 5 houses on a line that comes off main line, the power company never gets in a hurry to restore it. So nice to know, that I no longer have to worry if power outage occurs while I am at work or it is out for extended periods. I now have heat, a/c, & total power with my Generac.
