Things to Know Before You Buy a Generator for House
Introduction
Power outages can be both inconvenient and disruptive, particularly when they occur unexpectedly. Whether you live in an area prone to severe weather, face regular electricity supply issues, or simply want to be prepared for any emergency, investing in a generator for your house can be a wise decision. In this comprehensive guide, we'll explore the key factors to consider when purchasing a generator for household use. From understanding the types of generators available to sizing your generator correctly and estimating costs, this article will equip you with all the information you need to make an informed decision.
Types of Generators for Households
Before delving into the specifics, it's essential to understand the different types of generators available for household use. The two most common options are portable generators and standby generators.
Portable Generators
- Portability: As the name suggests, portable generators are designed to be moved easily. They're often mounted on wheels, making them suitable for a variety of applications.
- Fuel Type: Portable generators can run on various fuels, including gasoline, propane, or diesel. The choice of fuel impacts the generator's runtime and efficiency.
- Power Output: Portable generators typically provide a lower power output, ranging from 1,000 to 10,000 watts. This is suitable for running essential appliances and lights during a power outage.
- Affordability: Portable generators are generally more affordable compared to standby generators.
Standby Generators
- Permanent Installation: Standby generators are permanently installed on a concrete pad near your house and connected to your home's electrical system.
- Fuel Source: These generators often run on natural gas or propane, ensuring a continuous power supply during extended outages.
- Power Output: Standby generators are capable of delivering higher power outputs, ranging from 5,000 to 20,000 watts or more, enabling you to power your entire house.
- Automatic Operation: Standby generators are equipped with an automatic transfer switch, ensuring a seamless transition to backup power when the main power source fails.
Assessing Your Power Needs
Determining the appropriate size and capacity of your generator is crucial. To ensure that you select the right generator for your household, consider the following factors:
- Load Calculation: Conduct a load calculation by listing all the appliances and devices you want to power during an outage. Determine the wattage requirements of each item and add them up to get the total load. Ensure your generator can handle this load.
- Essential vs. Non-Essential Items: Differentiate between essential items, such as refrigerators, heating/cooling systems, and medical equipment, and non-essential items like TVs and entertainment systems. Your generator should prioritize powering the essentials.
- Start-Up Surge: Some appliances, like refrigerators and air conditioners, require extra power when they start up. Be sure your generator can handle these surge loads.
- Sizing for Future Needs: Consider potential future needs when sizing your generator. A larger generator can accommodate expanding power requirements.
Generator Fuel Type
The choice of fuel for your generator can significantly impact its performance, convenience, and cost. The main options include:
- Gasoline: Gasoline generators are readily available and can be a cost-effective choice. However, they require proper storage and can go bad over time.
- Propane: Propane generators offer a clean-burning fuel source and are less likely to degrade over time. Propane is typically stored in tanks on your property.
- Diesel: Diesel generators are known for their fuel efficiency and longevity. They are suitable for long-term backup power solutions.
- Natural Gas: If your house has a natural gas supply, a natural gas generator can be a convenient and low-maintenance option.
Automatic vs. Manual Start
Consider how you want to start and operate your generator during a power outage:
- Automatic Start: Standby generators are equipped with an automatic transfer switch that seamlessly activates the generator when the power goes out. This is a hands-off solution that ensures uninterrupted power to your home.
- Manual Start: Portable generators require manual operation. You'll need to start them, connect them to your home's electrical system using extension cords or a transfer switch, and manage the fuel supply.
Generator Placement
The location of your generator is critical for safety and functionality. Here are some key considerations:
- Local Regulations: Check your local building codes and regulations regarding generator placement, noise restrictions, and fuel storage.
- Ventilation: Generators emit exhaust fumes that can be harmful if not properly ventilated. Ensure there's adequate space and ventilation to dissipate exhaust gases safely.
- Distance from Home: Place your generator a safe distance from your house to prevent carbon monoxide from entering your home. Consult the manufacturer's guidelines for the recommended distance.
- Elevated Platform: Consider placing the generator on an elevated platform to protect it from flooding or standing water during heavy rain.
Noise Level
Generators can be noisy, so it's essential to consider the noise level when choosing one for your household. In general, standby generators tend to be quieter than portable ones. However, the specific model and manufacturer can influence noise levels. Some generators come with noise-reduction features like sound-insulated enclosures.
Maintenance and Service
Regular maintenance is crucial to keep your generator in good working condition. This includes oil and filter changes, battery checks, and ensuring the fuel supply is stable. Additionally, you should have a service plan in place to address any issues promptly.
Generator for House - Cost Considerations
The cost of purchasing and installing a generator for your house can vary significantly based on several factors:
- Generator Price: The cost of the generator itself depends on its size, type, and brand. Standby generators are generally more expensive than portable ones.
- Installation Costs: Professional installation is recommended for standby generators. The installation cost can be influenced by factors like the complexity of the installation, required permits, and local labor rates.
- Fuel Costs: Consider ongoing fuel costs, especially if you opt for natural gas or propane generators.
- Maintenance Expenses: Factor in routine maintenance costs to keep your generator in optimal condition.
- Total Cost of Ownership: Take into account the total cost of ownership, which includes the initial purchase, installation, and ongoing operating costs.
Backup Power Duration
The runtime of your generator on a single tank of fuel is an essential factor to consider. This will determine how long your generator can sustain your power needs during an outage. Be sure to choose a generator that can provide sufficient backup power based on the potential duration of outages in your area.
Warranty and Support
Look for generators that come with a manufacturer's warranty and reliable customer support. A good warranty can give you peace of mind and save you money on potential repairs or replacements.
Conclusion
Investing in a generator for your house can provide peace of mind and comfort during power outages. By considering the types of generators, assessing your power needs, choosing the right fuel source, and evaluating factors like automatic vs. manual start, placement, noise level, maintenance, and costs, you can make an informed decision. Ensure that your generator purchase meets the specific needs of your household, keeping your family safe and comfortable even when the lights go out.
