Westinghouse vs Champion Home Standby: Which to Pick?

What home standby generators do

A home standby generator is permanently installed outside your house, connected to your electrical panel through an automatic transfer switch. When utility power fails, the generator starts itself within seconds and feeds electricity to selected circuits. Unlike portable generators, standby units run on natural gas or liquid propane, so you do not need to refuel during an outage.

Both Westinghouse and Champion offer standby generators built around air-cooled engines, rated in kilowatts (kW) of continuous output. The size you need depends on which circuits you want to back up, not on the size of your home alone. A typical approach is to prioritize essentials: refrigeration, heating system blowers, well pumps, lighting, and electronics. See what size generator for home backup for a load calculation method.

Because a standby generator is wired into your home, installation is not a DIY task. A licensed electrician must install the transfer switch, connect the generator to your fuel line, and often obtain a permit. The manual vs automatic transfer switch article explains why automatic operation is the standard for standby systems.

Power output: matching capacity to your load

Westinghouse and Champion both publish generator ratings in kilowatts for natural gas and for liquid propane. A generator's output is lower on propane than on natural gas because of the fuel's energy density. When comparing models, check the rating for the fuel you plan to use.

For a typical home backup scenario, a generator in the 10 to 14 kW range can run a refrigerator, a few lighting circuits, a furnace blower, and a television or computer. A larger unit in the 16 to 22 kW range is needed if you also want to power central air conditioning, an electric water heater, or a well pump. The best home standby generators guide supports larger installations.

Westinghouse's larger standby models emphasize peak output during motor start events. Champion's lineup focuses on steady, rated output at a lower cost. Either approach works; the key is to compare rated continuous output on the fuel you intend to use. The generator running watts vs starting watts article explains why motors need extra starting power.

Transfer switch options and installation

Every home standby generator requires a transfer switch so that generator power never back-feeds into the utility grid, which is dangerous for line workers and can damage your equipment. Westinghouse and Champion standby models are typically sold as kits that include the generator, the automatic transfer switch, and a control panel.

The transfer switch may be a load center style that replaces your main breaker panel, or a subpanel that moves selected circuits onto generator power. A load center switch is simpler if you want the generator to back up the whole panel, but it must be large enough to handle your entire electrical load. A subpanel approach lets you choose a smaller generator. The article on generator transfer switch types explains the differences.

Also consider the transfer switch's amp rating. A 100-amp switch supports a larger generator and more circuits than a 50-amp switch. Both Westinghouse and Champion provide switches sized to each generator model, but verify the rating before purchase.

Fuel: natural gas vs liquid propane

Most home standby generators are dual-fuel, capable of running on natural gas supplied by your utility line or on liquid propane from an on-site tank. Natural gas is convenient because it is piped directly to the generator, and it does not require tank refilling. Liquid propane stores well and can be kept in larger quantities, but you must monitor the tank level. The propane vs natural gas generators comparison covers both in detail.

The U.S. Energy Information Administration notes that natural gas is a fossil fuel composed mainly of methane (source: EIA). When you connect a generator to your natural gas line, the utility supplies the fuel continuously as long as the gas system is intact. During a widespread outage, natural gas service often remains available, which is a major advantage over relying on a propane tank that could run empty.

Champion and Westinghouse both design their standby generators for either fuel, but the output rating changes with fuel type. Check the spec sheet for the fuel you plan to use. If you have a large propane tank already, either brand will work; if you have natural gas at your home, confirm the generator is set up for that connection.

Features and controls: monitoring and maintenance

Westinghouse standby generators include a controller with an LCD display, exercise timer, and remote monitoring via Wi-Fi. The mobile app lets you check generator status, see fault codes, and run a manual test from your phone. Champion's controllers tend to be simpler, with a digital display and physical buttons, but they may lack remote monitoring on some models. If you want to check your generator from a distance, look for a model with Wi-Fi or cellular connectivity. The generator remote start systems article discusses monitoring options.

All standby generators are designed to run an exercise cycle, typically once a week, to keep the engine and battery ready. The controller starts the generator, runs it under load for a set time, and shuts it down automatically. This keeps the battery charged and the engine lubricated. See the generator exercise schedule guide for how to set one up.

Battery maintenance is critical because standby generators start automatically, often during a storm. A weak battery can leave you without backup power. Both brands use a standard 12V battery that the controller charges during operation. The generator oil change interval guide covers a maintenance timeline.

Safety: CO detection and installation rules

Carbon monoxide safety is non-negotiable. Standby generators are installed outdoors, but CO can still enter a home through windows, doors, or vents if the generator is placed too close. The U.S. Consumer Product Safety Commission warns that generator exhaust contains carbon monoxide, a poison that can incapacitate and kill within minutes, and recommends never operating a generator indoors or in garages, basements, or sheds (source: CPSC generators page). The CDC advises operating generators outdoors, more than 20 feet away from windows, doors, and vents, and installing CO alarms on every level of the home (source: CDC CO basics).

Westinghouse and Champion standby generators may include a built-in CO sensor that shuts down the engine if CO is detected near the unit. This is a useful layer of protection, but it does not replace home CO alarms. Install battery-operated or battery-backup CO alarms near sleeping areas and on every level. The generator CO sensor requirements article explains the standard.

Also follow the manufacturer's installation clearance requirements. A standby generator must sit on a level surface, away from building openings, and with enough clearance for exhaust and air intake. The generator safety checklist outdoor use guide provides a practical list.

What to pick for your use

Questions

Can a Westinghouse or Champion standby generator run on natural gas?

Yes, both brands offer standby generators that run on natural gas or liquid propane. Output is lower on propane, so check the spec sheet for the fuel you plan to use.

Do I need a transfer switch for a standby generator?

Yes. A standby generator is permanently wired through an automatic transfer switch, which isolates your home from the grid during an outage and prevents dangerous back-feeding. The switch is included in the generator kit.

How do I decide between 12 kW and 20 kW?

List the circuits you want to back up, then add up their running watts. A 12 kW generator covers refrigeration, lights, and a furnace fan; 16 to 20 kW is needed for central air conditioning or an electric water heater.

Do Westinghouse and Champion standby generators have CO sensors?

Many models include a built-in carbon monoxide sensor that shuts down the engine if CO is detected. Always install separate home CO alarms on every level and outside sleeping areas, per CPSC and CDC guidance.

Can I install a standby generator myself?

No. Installation requires connecting to your home's electrical panel and fuel line, which must be done by a licensed electrician and often a plumber or gas fitter, following local codes and the manufacturer's instructions.

Which brand is more reliable?

Both use proven air-cooled engine designs. Reliability depends more on correct sizing, professional installation, and regular maintenance, such as weekly exercise runs and annual oil changes, than on brand alone.
