The team of professionals from Seattle Plumbing, Drain and Rooter Pros has repaired and replaced thousands of hot water heater units. We discussed with our master plumbers some great tips to consider when you’re replacing a hot water heater, there are key factors to consider. Size, energy efficiency, fuel type, cost considerations, and installation requirements all play a role. In our experience, these are the most important variables homeowners should be considering.

You’ll need to determine the right size for your needs, choose an energy-efficient model, decide on the fuel type that suits your preferences, weigh the costs involved, and ensure you meet the necessary installation requirements.

By considering these factors, you can make an informed decision and find the perfect replacement for your hot water needs.


When replacing a hot water heater, first determine the appropriate size by considering the number of people in your household and their hot water usage. This is crucial because a water heater that’s too small won’t meet your needs, while one that’s too large will waste energy and money.

Start by calculating the peak demand, which is the maximum amount of hot water used during a busy hour. You can estimate this by considering activities such as showering, dishwashing, and laundry.

On average, a person uses around 10 gallons of hot water per day. Multiply this by the number of people in your household to get a rough estimate of your daily hot water usage.

Energy Efficiency

To maximize energy efficiency, consider the rating and fuel type of the hot water heater you’re replacing.

The rating of a hot water heater is typically indicated by its Energy Factor (EF). The higher the EF, the more energy efficient the unit is. Look for a water heater with a high EF to ensure lower energy consumption and reduced utility bills.

Additionally, consider the fuel type of the hot water heater. Electric water heaters are generally more energy efficient than gas water heaters, as they don’t require a pilot light. However, if you have access to natural gas, a gas water heater may be more cost-effective in the long run, as gas is typically cheaper than electricity.

Carefully evaluate your options to make the most energy-efficient choice for your needs.

Fuel Type

Consider the fuel type of your hot water heater to determine the most cost-effective and efficient option for your replacement. The fuel type plays a crucial role in determining the overall performance and energy efficiency of your hot water heater. There are several fuel options available, including natural gas, propane, electric, and solar. Natural gas and propane heaters are known for their high efficiency and affordability. They can quickly heat water and are suitable for larger households.

Electric water heaters, on the other hand, are more expensive to operate but have a lower upfront cost. Solar water heaters are the most environmentally friendly option, as they use renewable energy from the sun. However, they may require a larger upfront investment. Consider your budget, availability of fuel sources, and environmental impact when choosing the fuel type for your hot water heater replacement.

Cost Considerations

One important factor to consider for cost considerations is the heater’s lifespan. When replacing a hot water heater, it’s crucial to evaluate how long the new unit is expected to last. Generally, a higher quality and more expensive heater tends to have a longer lifespan. While the initial cost might be higher, it can save you money in the long run by reducing the frequency of replacements.

Additionally, you should take into account the energy efficiency of the heater. A more efficient unit may have a higher upfront cost, but it can significantly lower your monthly energy bills.

It’s also important to factor in the installation cost. Hiring a professional plumber might be necessary, and their fees can vary.

Lastly, consider any potential maintenance costs, such as regular servicing or repairs, over the lifespan of the heater.

Installation Requirements

When replacing your hot water heater, it’s important to understand the installation requirements. These requirements ensure that your new water heater is properly installed and functions efficiently. First, you need to determine the location for the new heater. It should be installed in a well-ventilated area, away from flammable materials. Next, consider the size and capacity of the heater. Make sure it can meet your household’s hot water demands.

Additionally, you need to check if any modifications are needed for the plumbing and electrical connections. It’s crucial to hire a professional plumber or electrician to carry out the installation. They’ll ensure that all safety codes and regulations are followed.
