5 out of 5 stars review

Runs my whole house!

I'll be ready for the next extended power outage with the WGen14500tfc! I piped it up to natural gas and it started on the first attempt. After the 5-hour break-in period, I tested it to see if it would run my entire house and it did easily. This includes my 5-ton central A/C (with soft start), but I didn't run my electric oven or dryer, which I wouldn't do in a power outage anyway. Very happy with the purchase!

I expect the best from Westinghouse

I took delivery today. I was hoping to have a clear path to hooking up to Natural Gas but my plumber says that he can't provide a NG hookup until he gets more info from gas company because there is no included spec for the potential BTU output included with the documentation. No problem using other fuels.

Great generator (beast)

I just purchased the Westinghouse WGEN12000DF generator After my electrician visited to install my transfer panel, I hooked everything up and started my generator, Everything was wonderful. 60g 4500W hot water tank, 12000btu ductless heat pump, kitchen light and small round stove, TV and computer all worked like a charm with the low THD -5%. I'm ready for the next storm and the next power outage. Just one problem, have some friends with you so you can get this generator out of its wood create. Be careful when you connect sensitive electronic devices such as a heat pump you cannot use the low idles. Variation with the Herz. This should be indicated on the product sheet.

Great Generator for whole home hurricane

I live in florida and bought this after IAN. I have used it twice since during helene and Milton. It ran my whole house minus one or two rooms to i clude a 4 ton ac, two refrigerators, a deep freezer, microwave, 3 bedrooms and living room. It was flawless. Propane and gas switch over is easy. The best part is an oil change is so simple with the extended hose. The nrst home purchase i ever made.

So far so good......

Just received and setup the generator. Overall its a very nice unit. Had my electrician put a hookup on my home to plug this into when power goes out....and I say "when" because it happens too often. Fairly quiet for the engine size, looks good, lots of connections. After setup I ran it for a bit just as a test. My electrician is coming back to test it on the house once my adapter cord arrives. A few items that I noticed while getting this setup which need to be addressed by the design/development team at Westinghouse..... 1. The oil funnel provided is OK but hard to get the angle to the engine fill and oil can spill back out of the provided funnel because the angle is so flat. Why not put an oil fill tube for easier access/filling for a unit at this price point 2. The oil dipstick is difficult to pull and then even more difficult to insert back without a gap that allows leaks. The wire handle is flimsy and this could be so much easier with a better design. 3. The assembly for wheels requires flat washers as spacers between the plastic wheels and step on the axle shaft. However, there is NO space to fit the washers and get the clevis/cotter pins installed so I had to leave the washers off. Just a bad design on this item. 4. Connecting the battery is a pain. The positive was connected already but the ground was not. However, you have to lay on your side on the ground and try to fit your hands inside the frame and feel for the bolt hole to assemble the nut and tighten it down. There is no room for this unless one has lady hands. Moving the battery outward would allow better and easier access to connect the battery ground. Just a few items that I noticed. None are deal killers and some are one time tasks unless/when you have to change the battery. Overall I really like the unit and looking forward to testing on the house this next week. My expectations are high for a quality unit to have as a backup generator.

Powerful Generator

Bought last month to prepare for hurricane season here in the Houston,Tx area. Connected to natural gas and ran a test on the house and was able to run both ac units without soft starts and whatever else was on in the house. The generator kept up with the load and never bogged down. I am ready for the next power outage.

Great power and features

I bought this generator over a year ago, and didn't run it until about two weeks ago. I mostly use it to operate a Hobart 250-volt Mig welding machine. I use the propane feature, which supplies sufficient current to operate without hesitation. I really, really like this generator.

THE ONLY GENERATOR YOU WILL EVER NEED

THE BEAST IS WHAT THIS IS. ALL 432 LB'S OF HER. AFTER ATTACHING THE WHEELS AND MANEUVERING THIS THING OFF THE CRATE, IT WAS AN EASY PROCESS TO GET THE BEAST READY FOR FUTURE POWER GRID FAILURES. BOLTED ON THE LIFT BAR, FILLED THE CRANKCASE WITH THE 1.6L OF SUPPLIED OIL, CONNECTED THE BATTERY TERMINALS, ADDED SOME GAS, PAIRED THE REMOTE START FOB. THE BEAST STARTED ON THE SECOND TRY AND RAN WELL. I WILL ADD AS I READ QUESTIONS/ANSWERS ONLINE ABOUT THIS UNIT, I SAW NEW OWNERS SAY THAT AN OIL FILTER WAS NOT DESIGNED ON THIS TWIN MOTOR. I FOUND THE FILTER LOCATED FORWARD FROM THE MUFFLER ON THAT SIDE, LOWER SECTION OF THE MOTOR AN OIL FILTER RESIDES. THIS GENERATOR WILL GIVE MY FAMILY A GOOD SENSE OF SECURITY WHEN THE NEXT HURRICANE HIT MY AREA OF FLORIDA.

Well Built

After our loss of power generation due to extended freezing weather in February 2021, I knew I was going to buy a solution. It took a couple of months to evaluate needs and choices, then another month to compare retail prices and availability. I was happy to find this U.S.-engineered Westinghouse packed with features and exactly what I need. An electrician installed a 200 amp, double throw transfer switch and 50 amp receptacle for this generator. This will allow me to switch over to generator power and add load incrementally. It handled my largest power users without a quiver. I am very happy with it.
