Finally, you’ll want to read customer reviews to see what other people have to say about the water heaters you’re considering.

Consider Your Hot Water Needs

The first step in choosing the best whole house electric tankless water heater for your home is to determine your hot water needs. This will help you choose a water heater that is the right size and capacity for your home. To do this, you’ll need to consider the following factors⁚

• The number of people in your household⁚ The more people in your household, the more hot water you’ll need.
• Your hot water usage habits⁚ Do you take long showers? Do you wash dishes by hand? Do you have a large family that uses a lot of hot water?
• The size of your home⁚ A larger home will require a water heater with a larger capacity.

Once you’ve considered these factors, you can use the following formula to estimate your hot water needs⁚

Hot water usage (gallons per day) = (number of people in household) x (average hot water usage per person per day)

The average hot water usage per person per day is about 20 gallons. So, for example, a family of four would need a water heater that can provide about 80 gallons of hot water per day.

Once you know your hot water needs, you can start shopping for a water heater that is the right size and capacity for your home.

Choose the Right Size and Capacity

Once you know your hot water needs, you can start shopping for a water heater that is the right size and capacity for your home. The size of a water heater is measured in gallons per minute (GPM). The capacity of a water heater is measured in gallons.

The GPM rating of a water heater tells you how many gallons of hot water the water heater can deliver per minute. The capacity of a water heater tells you how many gallons of hot water the water heater can store.
To choose the right size and capacity for your home, you’ll need to consider the following factors⁚

• Your hot water needs⁚ The higher your hot water needs, the higher the GPM rating and capacity you’ll need.
• The number of people in your household⁚ The more people in your household, the higher the GPM rating and capacity you’ll need.
• Your hot water usage habits⁚ If you take long showers or wash dishes by hand, you’ll need a water heater with a higher GPM rating and capacity.
• The size of your home⁚ A larger home will require a water heater with a higher capacity.

Once you’ve considered these factors, you can use the following table to choose the right size and capacity for your home⁚

| Number of people in household | GPM rating | Capacity (gallons) |
|—|—|—|| 1-2 | 6-8 | 20-30 |
| 3-4 | 9-11 | 30-40 |
| 5-6 | 12-14 | 40-50 |
| 7 or more | 15 or more | 50 or more |

If you’re not sure what size and capacity you need, it’s always best to err on the side of caution and choose a water heater that is slightly larger than you think you need.

Compare Energy Efficiency Ratings

Once you’ve chosen the right size and capacity for your home, you’ll need to compare energy efficiency ratings to find a water heater that will save you money on your energy bills. The energy efficiency rating of a water heater is measured by its Energy Factor (EF). The EF is a ratio of the amount of hot water the water heater produces to the amount of energy it consumes.

The higher the EF, the more energy efficient the water heater is. Water heaters with an EF of 0.90 or higher are considered to be high-efficiency water heaters.

To compare the energy efficiency of different water heaters, you can use the EnergyGuide label. The EnergyGuide label is a yellow and black sticker that is attached to all new water heaters. The EnergyGuide label shows the water heater’s EF, as well as its estimated annual operating cost.

When comparing energy efficiency ratings, it’s important to keep in mind that the EF is only a measure of the water heater’s efficiency at producing hot water. It does not take into account the water heater’s standby losses. Standby losses are the amount of heat that the water heater loses when it is not in use.
Water heaters with a higher EF will typically have lower standby losses. However, it’s important to compare the standby losses of different water heaters before making a decision.

You can find the standby losses of a water heater in the product specifications. Standby losses are typically measured in watts. The lower the standby losses, the better.

By comparing energy efficiency ratings and standby losses, you can choose a water heater that will save you money on your energy bills.
