Welcome to our electric water heater sizing guide! Finding the right water heater size is crucial when it comes to replacing your existing one. Fortunately, we’re here to help you navigate through this decision with ease. With our water heater size calculator and expert advice, you’ll be able to choose the perfect water heater size for your needs.

At Home Service Plus, we offer a range of water heater sizes, including 30-, 40-, 50-, and 75-gallon natural gas water heaters. To determine the best size for your household, consider factors such as the number of family members, bathrooms in your home, and whether you use an automatic dishwasher.

For example, a family of two with one bathroom and a clothes washer may find that a 30-gallon water heater is sufficient. If you have additional bathrooms, we recommend adding 3-1/2 gallons for each one.

Another important consideration is the first-hour rating, which tells you the amount of hot water the water heater can deliver in one hour. By following a simple procedure based on your hot water usage during the hour of highest demand, you can determine the first-hour rating that suits your needs.

Factors for Sizing Electric Water Heaters

When it comes to sizing an electric water heater, there are several important factors to consider. By taking these factors into account, you can ensure that you choose the right size water heater for your household’s needs. Here are some electric water heater sizing tips to help guide you:

1. Number of Family Members and Bathrooms

The size of your family and the number of bathrooms in your home play a crucial role in determining the right water heater capacity. As a general guideline, adding 3-1/2 gallons to the tank capacity for each additional bathroom can help meet your hot water needs.

2. Automatic Dishwashers

If you have an automatic dishwasher, it’s important to account for the additional hot water usage. You should add an extra five gallons to the total tank capacity to ensure an adequate supply of hot water.

3. First-Hour Rating

The first-hour rating is another important consideration when sizing an electric water heater. It refers to the amount of hot water the water heater can deliver in one hour. To determine the right first-hour rating for your household, consider the hour of the day when you use the most water. Use an activity chart to calculate the hot water usage for each activity during that hour, and find a water heater with a first-hour rating close to your total hot water usage.

Remember, it’s crucial to consider both the tank capacity and the first-hour rating when determining the right size for your electric water heater. By considering these factors, you can ensure that your water heater meets the hot water demands of your household.

Choosing the Right Water Heater Size

When it comes to finding the perfect water heater size for your home, there are a few key factors to consider. First and foremost, you’ll want to think about your household’s hot water needs and your personal priorities.

The number of people living in your home, their showering habits, the presence of bathtubs, and the use of other hot water appliances should all be taken into account. This will help determine the optimal size that can meet your daily hot water demands.

Storage capacity and the ability to quickly reheat the water in the tank are also crucial considerations when choosing a water heater size. If you frequently need to fill a large bathtub or have multiple showers running at the same time, a tank water heater with ample storage capacity might be the best choice for you.

On the other hand, if you require a continuous flow of hot water for sustained use, such as multiple back-to-back showers, a tankless water heater could be more suitable. These compact units provide hot water on demand without the need for a storage tank, making them a space-saving option.

Keep in mind that larger storage tank water heaters may require more space for installation, so consider your available space when making your decision. Lastly, it’s important to note that a water heater alone cannot provide instant hot water. However, features like built-in recirculation pumps can help deliver hot water more quickly.
