Questions and answers
- Which is better for running a furnace and fridge during an outage?
- Both handle it. The Westinghouse's 9,500 running watts cover a typical furnace, fridge and lights for far less money. The DuroMax gives more headroom and cleaner power if you add electronics.
- Is the DuroMax worth the extra cost?
- Only if you need inverter power or the extra 1,000 running watts. The Westinghouse does the same 50A backup job for about $1,650 less.
- Which lasts longer on a tank?
- The Westinghouse, up to 15 hours on 6.6 gallons. The DuroMax runs 10.8 hours at 50% load on 8 gallons.
- Can both connect to a 50A inlet or interlock?
- Yes. Both have a 14-50R outlet and are built for transfer switch or interlock hookup.
- Which is quieter?
- The DuroMax is rated 66 dB at 25% load. Westinghouse does not publish a noise figure for the WGen9500DFc, so compare in person if noise matters.
