What generator capacity works best for a 2,000 square foot home?

A 2,000 square foot home typically needs 15,000-20,000 watts for whole-home coverage. The actual requirement depends on your HVAC system type—homes with heat pumps need larger generators than those with gas furnaces. Proper sizing considers your specific well pump, heating system, and appliances rather than square footage alone.

Can a 7,500-watt generator power an entire home?

A 7,500-watt generator powers essential circuits only—well pump, refrigerator, gas furnace blower, and lights—but not whole-home coverage. You won't have hot water, internet, or the ability to run multiple appliances simultaneously. Most homes need 10,000-15,000 watts for comfortable living during outages with heat pump systems and all typical appliances operating.

What's the reason for maintaining generator distance from your home?

Portable generators should be placed outdoors 20+ feet from your home for carbon monoxide safety. Generator exhaust contains deadly carbon monoxide that can seep into homes through windows, doors, and foundation cracks. This distance protects families from carbon monoxide poisoning, which causes dozens of deaths during power outages every year.
