    • Awesome Product (5 STARS)
Style: 28000 Watts - Tri Fuel - CO Sensor
Just plain awesome. Just a couple of days in... This thing is large and heavy and you will need help getting it off of the pallet it is delivered on (an overhead crane or engine lift would be VERY helpful) It will for sure take care of whole house power when needed. It is a bit loud but for myself I do not care, it will take care of power requirements in an emergency. I cannot speak about fuel efficiency yet as it is too new, but If gasoline (17-gallon tank) is used as a backup for propane or natural gas (I prefer these over gasoline so carbon is not built up in the cylinders) I believe it should operate great for many hours. It was very easy to put together having only to install the wheels, lift bar and hook up the negative post of the battery. After assembly, I hooked up my propane bottle and opened the valve, set the fuel source to propane, turned on the battery, pressed the remote start button and it started right up. I look forward to having this generator set up as a permanent fixture to power our home when needed. We lose power around here too often. ... show more

    • Westinghouse WGen20000TFc- What a beast!
Style: 28000 Watts - Tri Fuel - CO Sensor

Review Image by Brian
Our WGen20000TFc arrived on time and in Preston’s condition. I was worried when I saw it was shipped from Amazon via Ceva logistics based off all of the negative reviews but I experienced excellent service and delivery from them. The generator is a beast of a machine and you will definitely need some method to get it off of the pallet once the wheels, handle and lifting bracket are installed. I’m lucky and have a tractor with a front end loader, if you aren’t that fortunate you may have to solicit some help from some very strong friends or build some sort of ramp. Had a little trouble getting the wireless remote synced , the instructions don’t mention pressing a red button on the side of the control panel but a quick call to their customer support and we got it synced. Started right up with no difficulties and I let it run for the five hour break in period alternating loads as the instructions indicated. Had to install a soft start in order for it to run my heat pump, when the compressor kicks in it draws about 70 amps and would trip the 50 amp breaker on the generator. After the soft start it ran my heat pump just fine. Now we can enjoy a warm house, cool, wash clothes and even take a hot shower thanks to this generator. For about 25% of the cost of an automatic whole house generator I’m quite pleased. Things to consider, this thing is very loud, used a decimeter all around the generator from about 10 feet away and it averaged 85 decibels, I live in the country so not a big deal but if you lived in town or in a subdivision your neighbors would not like you. Also this thing sucks down the gas, based on my estimates I would probably have to fill it twice in 24 hours if I ran it continuously. Looking into possibly getting a 120 gallon or larger propane tank just for the generator. Do love that it has the capability to run on gasoline, propane or natural gas. During our last outage propane was in short supply but gasoline was available. All in all very pleased with my purchase but will some day invest in an automatic whole house, this thing is very difficult to keep fueled with 5 gallon gas jugs. ... show more

    • runs our whole house
Style: 28000 Watts - Tri Fuel - CO Sensor
This thing is a beast and easy to use. You'll want help getting it off the palate when it arrives but it's very easy to put the wheels on and get it going. Comes with easy to follow instructions too. We just got it through the 5 hour break in period and we hooked it up to our 2100sqft home for a test run, and it works as expected. It runs our house like we're connected to the grid. This includes our AC. I hope I never need it, but I feel good knowing this thing has the power to run the house. 10/10 would recommend. ... show more
