When it comes to living in a 3-bedroom house, having a backup generator can be a lifesaver during a power outage. However, choosing the right size generator for your needs can be a daunting task. In this article, we’ll explore the factors to consider when choosing the right size generator for a 3 bedroom house and how to calculate the size of generator needed.
Factors to Consider When Choosing a Generator for a 3 Bedroom House
Power requirements: The power requirements for a 3 bedroom house will vary depending on the appliances and electronics that you have. For example, a refrigerator and freezer will require more power than a lamp or phone charger.
Size of the generator: The size of the generator will depend on the power requirements of your house. It’s important to choose a generator that can handle the maximum power requirements of your house.
Fuel type: There are different types of fuel used by generators, including gasoline, propane, and diesel. Each type has its own pros and cons, so it’s important to consider which type will work best for your needs.
Noise level: The noise level of generators can vary, and it’s important to consider this when choosing a generator. Some generators are designed to be quieter than others, which may be important if you live in a densely populated area.
Cost: The cost of generators can vary widely depending on the size, fuel type, and brand. It’s important to consider the cost when choosing a generator, but it shouldn’t be the only factor you consider.

How to Calculate the Size of Generator Needed for a 3 Bedroom House
To calculate the size of the generator needed for a 3 bedroom house, you’ll need to determine your power requirements. Here’s how:
Make a list of all the appliances and electronics that you’ll need to run during a power outage, including the wattage of each item.
Determine the starting wattage and running wattage for each item on your list. The starting wattage is the power required to start the item, while the running wattage is the power required to keep the item running.
Add up the starting wattage and running wattage for all the items on your list. This will give you the total power requirements for your house.
Choose a generator that can handle the maximum power requirements of your house. It’s always better to choose a generator that’s slightly larger than what you need, rather than one that’s too small.
Sample Calculation
Let’s say that your 3 bedroom house has the following appliances and electronics:
- Refrigerator: 600 watts starting, 200 watts running
- Freezer: 800 watts starting, 200 watts running
- Television: 400 watts starting, 100 watts running
- Lights: 300 watts
To calculate the total power requirements for your house, you would add up the starting wattage and running wattage for each item:
- Refrigerator: 600 + 200 = 800 watts
- Freezer: 800 + 200 = 1000 watts
- Television: 400 + 100 = 500 watts
- Lights: 300 watts
The total power requirements for your house would be 2,600 watts. To be safe, you should choose a generator that can handle at least 3,000 watts.
How big of a generator do I need to run a 3 bedroom house?
The size of generator you need to run a 3 bedroom house depends on your power requirements. Generally, a 3 bedroom house would require a generator with a capacity of at least 5,000 watts or more. However, it’s important to calculate the specific power requirements of all the appliances and electronics you want to power with the generator.
To calculate the appropriate size of the generator, you can add up the power consumption of all the appliances and electronics you want to run simultaneously during a power outage. This information can be found on the manufacturer’s label or in the user manual. Once you have determined the total power consumption, you should add a margin of safety, usually about 20% more, to account for the startup surge of some appliances.
Keep in mind that larger generators may be louder and more expensive than smaller ones, so it’s important to balance your power needs with your budget and noise tolerance. You may also want to consider the fuel type, as some generators run on gasoline, propane, or natural gas.
Consulting with a professional electrician or generator specialist can also be helpful in determining the appropriate size of the generator for your 3 bedroom house.
Conclusion
In conclusion, choosing the right size generator for a 3 bedroom house is crucial to ensure that you have enough power to run all of your essential appliances and electronics during a power outage. Or when living in areas with unreliable electricity supply. To determine the appropriate size of generator, you should consider the power requirements of all appliances and electronics, as well as the fuel type, noise level, and cost. By taking these factors into consideration, you can find the generator that meets your needs and provides peace of mind during times of power outage. Remember to always follow the manufacturer’s instructions and safety guidelines when using a generator.
