1. Assess Your Household’s Hot Water Needs
Start by evaluating how much hot water your family uses daily. Larger families often need water heaters with higher capacity to meet their needs, especially during peak usage. For example:
- A single-bathroom home may require a 30-40 gallon tank.
- Homes with multiple bathrooms may need a 50-80 gallon model.
- Tankless systems should have a GPM (gallons per minute) rating that matches peak water use.
If your home has hard water, choose tanks designed to resist sediment buildup for better performance and durability.
2. Focus on Energy Efficiency
Energy-efficient models lower utility bills and reduce environmental impact. Look for models with high Energy Factor (EF) ratings, as these use less energy. Electric tankless water heaters are highly efficient, offering space-saving benefits and instant hot water delivery. Options include:
ENERGY STAR-certified models: These can save a family of four up to $550 annually.
- Heat pump water heaters: Though initially more expensive, these pay off within three years and may qualify for federal tax credits. Heat pump water heaters extract heat from the air to heat water, providing energy efficiency and long-term savings on utility bills.
Switching to an energy-efficient system provides reliable hot water and long-term savings.
3. Choose the Right Fuel Source
Your fuel source affects both cost and performance. Options include:
- Gas Water Heaters: Heat water quickly and are cost-effective for larger families. Proper venting is required for safe operation. A gas tank water heater can effectively supply a consistent amount of hot water, and switching to more efficient natural gas tankless units offers greater energy efficiency and saves space.
- Natural Gas: Natural gas models typically have lower energy costs compared to electric ones. They are efficient in terms of heating speed and provide economic benefits, though proper ventilation is necessary.
- Electric Water Heaters: Easier to install and suitable for smaller homes. However, they may consume more energy than gas models.
- Solar Water Heaters: These are ideal for reducing long-term costs and environmental impact but require a larger initial investment.
For smaller spaces or energy-conscious households, tankless systems are worth considering.
4. Consider Space Availability
Think about where your water heater will be installed. A storage tank water heater requires more room due to its size and the need to store heated water, but it is typically more affordable initially. A tankless water heater, with its compact design, is a great option for smaller spaces.
5. Plan for Maintenance Requirements

- Checking the anode rod regularly to prevent rust.
- Testing the TPR valve annually to ensure safe operation.
Tennessee Standard Plumbing offers water heater maintenance services in Knoxville, TN, ensuring your system runs efficiently.
6. Explore Features That Add Value
Modern water heaters often come with advanced features designed to enhance convenience and efficiency. These features may include:
- Digital controls: Allow you to set precise water temperatures and monitor energy usage.
- Wi-Fi connectivity: Enables remote control and troubleshooting through a smartphone app.
- Enhanced safety mechanisms: Provide protection against overheating or pressure issues.
Take the time to evaluate these options and choose features that align with your budget and household needs.
7. Work with a Trusted Professional
Consulting a professional can help you choose the best water heater for your home. Tennessee Standard Plumbing provides expert advice tailored to your household’s requirements, along with reliable installation and maintenance services.
Factor in Long-Term Costs and Savings
Beyond the purchase price, think about the long-term costs of owning and maintaining a water heater. This includes:
Energy Usage: Efficient models may cost more upfront but provide significant savings on utility bills over time.
- Lifespan: A well-maintained water heater typically lasts 10-15 years. Investing in a durable model can reduce the frequency of replacements.
- Maintenance and Repairs: Regular maintenance prevents costly repairs and ensures the unit runs efficiently.
Planning for these factors can help you make a more informed decision and avoid surprises down the road.
