How to Properly Size a Water Heater for Your Home 1

Understand Your Household’s Hot Water Consumption Habits

Before getting into the specifics of sizing a water heater for your home, it’s important to understand your household’s hot water consumption habits. Consider how many people are living in your home and their daily hot water usage. For instance, you should consider the number of showers taken per day, how long those showers last, and the time at which hot water is used (peak hours). Another thing to consider is whether the dishwasher and washing machine are used frequently, and whether more than one appliance is being used at the same time.

Determine Your Households’ Peak Hourly Demand for Hot Water

After considering your household’s hot water usage habits, you can determine your household’s peak hourly demand for hot water. This should be calculated based on the number of people in the household and the total hot water used during the busiest consumption period in your home. Generally, peak hours of hot water usage are in the morning and evening.

Determine Your Tank Size Requirements

Once you have an idea of your household’s hot water consumption habits and peak hourly demand for hot water, you can begin to calculate the size of the water heater required. There are two options for sizing: storage tank water heaters and tankless water heaters. Generally, storage tank water heaters are less expensive upfront, while tankless water heaters are more energy-efficient.

For a storage tank water heater, multiply your peak hourly demand rate by the number of gallons of hot water required during the two busiest hours of hot water usage. Add 10 percent of this number to account for immediate usage. The final number will be the minimum size of the storage tank water heater you need to meet the hot water needs of your household.

For tankless water heaters, the sizing calculation is a bit different. Calculate the flow rate and temperature rise required for hot water in your household and use that information to consult the manufacturer’s specifications to find a unit that meets your household’s needs.

Consider Your Household’s Available Fuel Source

Another important factor to consider is the fuel source you have available in your home. Most hot water heaters come in either an electric or gas-powered model. If you have natural gas available, it is generally more cost-effective to opt for a gas-powered model, since they have lower energy costs. Electric water heaters are more expensive to operate but are less expensive to install, and they may be your only option if you don’t have natural gas available in your home.

Consult With a Professional

While you can use these guidelines to get a general idea of what size water heater you need, it’s always a good idea to consult with a plumbing professional. They can take into account your specific home’s needs and provide more tailored recommendations. Additionally, a professional can ensure that your new water heater is installed correctly and safely.

In Conclusion

Properly sizing a water heater for your home is important to ensure that you have enough hot water for your household’s needs without overspending on energy bills. By understanding your household’s hot water consumption habits, determining peak hourly demand, considering fuel sources, and consulting with a professional, you can ensure that you choose the right size and type of water heater for your home.
