How do I know what size generator I need?

• <div><p>When <a href="https://www.angi.com/articles/what-size-generator-do-i-need.htm">choosing the right size generator</a> for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:</p><ul><li><p>Refrigerator: 600 watts</p></li><li><p>Large dehumidifier: 700 watts</p></li><li><p>Large window air conditioner: 1,400 watts</p></li><li><p>Water heater: 3,000 watts</p></li></ul><p>Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. </p></div>

Q: How much horsepower do I need?

• <div><p>If your home already has a grinder pump and you&rsquo;re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.</p></div>

Q: Do you need a permit to install a whole-house generator?

• <div><p>In many cases, you&rsquo;ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.</p></div>

Q: What size generator does my house need?

• <div><p>You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. </p><p>A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you&rsquo;ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.</p></div>

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. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.</p></div>

Generator Install questions, answered by experts

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together.

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace.

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.

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