Q: Can you switch fuel types for a whole-house generator?

• <div><p>In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel.

Generator Install questions, answered by experts

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

1,000 sq ft: 6–9 kW
1,500 sq ft: 7–10 kW
2,000 sq ft: 10–14kW
2,500 sq ft: 12–16kW
3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

The distance reduces the noise coming from the generator into your home.
It increases efficiency because you won’t have a voltage drop from this short of a distance.
Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

A 1,500 square foot home will likely need a 15kW to 20kW generator.

That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
