What Size Generator do i Need for a 2200 Square Foot House If you’re wondering what size generator you need for a 2200 square foot house, you’re not alone. Whether preparing for a power outage, planning off-grid living, or ensuring uninterrupted power during emergencies, choosing the right generator is crucial. This article will provide a detailed explanation to help you determine the right generator size for your home, including all the factors you should consider.
A generator ensures that essential systems, appliances, and devices in your home remain operational during power outages. In a house of 2200 square feet, your power needs will depend on several factors, including the number of appliances, HVAC systems, and your lifestyle.
Step 1: Understand Your Power Requirements
The first step in choosing a generator is calculating the wattage of the devices and appliances you want to power. Start by listing all the essential items and their wattage requirements. Here’s a breakdown of common appliances:
| Appliance/System | Starting Watts | Running Watts |
|---|---|---|
| Refrigerator/Freezer | 2200 | 700 |
| Central Air Conditioner | 4500 | 3500 |
| Electric Water Heater | 4500 | 4500 |
| Lights (10 Bulbs) | 600 | 600 |
| Sump Pump | 2200 | 800 |
| Electric Stove | 2000 | 2000 |
| Television | 400 | 400 |
| Computer | 800 | 800 |
| Microwave Oven | 1500 | 1500 |
Step 2: Add Up Total Wattag
For a 2200 square foot house, the typical starting wattage requirement can range from 12,000 to 20,000 watts, depending on the appliances you prioritize. Calculate your total wattage by adding the starting watts of all necessary items.
Step 3: Account for Surge Power
Surge power is the extra power needed to start appliances like refrigerators and air conditioners. To ensure your generator can handle surges, choose a model that provides at least 25% more wattage than your calculated total.
Recommended Generator Sizes for a 2200 Square Foot House
Here are some general guidelines for generator sizes based on power requirements:
| Power Requirement (Watts) | Recommended Generator Size |
|---|---|
| 12,000–15,000 Watts | 15 kW Generator |
| 16,000–20,000 Watts | 20 kW Generator |
| 20,000–25,000 Watts | 25 kW Generator |
For a typical 2200 square foot house with moderate energy use, a 20 kW generator is often sufficient to power essential systems and appliances.
