What to Look for in a Generator for an Electric Water Heater

Starting Wattage vs Running Wattage

An electric water heater draws a high startup surge, often 3–5 times its running wattage. A typical 40-gallon unit may run at 4,500 watts but spike to 12,000 watts on startup. You need a generator that delivers enough peak wattage to handle that spike without tripping. Models like the Westinghouse 14500 Peak Watt Tri-Fuel Home Backup excel here with 14,500 peak watts.

Running wattage matters for sustained operation. Once the water heater is running, it draws less power, but you may also power other appliances. Aim for a generator with at least 5,000 running watts to cover the heater plus a few lights or a fridge.

Fuel Type Flexibility

Dual fuel or tri-fuel generators let you switch between gasoline, propane, and natural gas. Propane stores indefinitely and burns cleaner, ideal for emergencies. Natural gas offers unlimited run time if connected to a gas line. The DuroMax XP13000HX 13,000-Watt Dual Fuel runs on gas or propane, giving you options during shortages.

Consider fuel availability in your area. If you have natural gas, a tri-fuel model like the Westinghouse 14500 Peak Watt Tri-Fuel provides the most flexibility. For camping or RV use, a smaller dual fuel inverter generator may suffice.

Noise and Portability

Open frame generators are louder but often cheaper and more powerful. Inverter generators run quieter and produce cleaner power, safe for sensitive electronics. If you plan to run the generator near living spaces, look for models under 65 dBA. The 8H Run Time, Ultra-Quiet model is rated below 59 dBA, ideal for neighborhoods with noise restrictions.

Portability features like wheels, folding handles, and lightweight designs matter if you need to move the generator from storage to use. Compact inverter generators like the WEN 3600-Watt Portable Inverter Generator are easier to transport than large home standby units.

Safety Features and Transfer Switch Compatibility

CO detection, automatic shutoff, and overload protection are essential for safe operation. Many modern generators include CO Watchdog or similar sensors that shut down the engine if carbon monoxide levels rise. For whole-home backup, choose a generator that is transfer switch ready, like the Westinghouse models with remote electric start.

Proper installation with a transfer switch prevents backfeeding and protects utility workers. If you are unsure about wiring, consult an electrician. For more on choosing equipment, see our guide on evaluating power needs.

Final Thoughts

Choosing the right generator for your electric water heater comes down to matching peak wattage with your heater’s startup surge and picking a fuel type that fits your situation. For whole-home backup with maximum flexibility, the Westinghouse 14500 Peak Watt Tri-Fuel Home Backup offers outstanding peak power and tri-fuel capability.
