5+ Best-Rated Electric Tankless Water Heaters for Limitless Hot Water


5+ Best-Rated Electric Tankless Water Heaters for Limitless Hot Water

A tankless water heater is a device that heats water on demand, without the need for a storage tank. This can save energy and space, and can provide a more consistent hot water supply than a traditional water heater. Electric tankless water heaters are powered by electricity, and are typically more efficient than gas-powered models.

There are many benefits to using a tankless water heater. They can save you money on your energy bills, as they only heat water when you need it. They can also provide a more consistent hot water supply, as you don’t have to wait for the tank to refill. Additionally, tankless water heaters are more compact than traditional water heaters, so they can be installed in smaller spaces.

If you’re considering replacing your old water heater, a tankless water heater is a great option to consider. They can save you money, provide a more consistent hot water supply, and take up less space.

1. Flow rate

The flow rate of a tankless water heater is one of the most important factors to consider when choosing a model for your home. The flow rate determines how much hot water the heater can deliver per minute. If you have a high demand for hot water, such as if you have a large family or if you frequently use multiple hot water appliances at the same time, you will need a heater with a high flow rate. Otherwise, you may run out of hot water or experience a drop in water pressure.

To determine the flow rate you need, consider the following factors:

  • The number of people in your household
  • The number of hot water appliances you use simultaneously
  • The size of your home
  • The climate in your area

Once you have considered these factors, you can use the following table to estimate the flow rate you need:

| Number of people in household | Number of hot water appliances used simultaneously | Size of home | Climate | Flow rate (GPM) ||—|—|—|—|—|| 1-2 | 1-2 | Small | Mild | 2.5-3.5 || 3-4 | 2-3 | Medium | Moderate | 4.0-5.0 || 5-6 | 3-4 | Large | Cold | 5.5-6.5 |

It is important to note that this is just a general guideline. To determine the exact flow rate you need, you should consult with a qualified plumber.

Choosing the right flow rate is essential for getting the most out of your tankless water heater. If you choose a heater with too low of a flow rate, you may run out of hot water or experience a drop in water pressure. If you choose a heater with too high of a flow rate, you may be wasting energy and money.

2. Energy efficiency

Energy efficiency is an important consideration when choosing any appliance, and tankless water heaters are no exception. The EF of a tankless water heater measures how efficiently it converts energy into hot water. The higher the EF, the more efficient the heater is.

There are several benefits to choosing a tankless water heater with a high EF. First, it can save you money on your energy bills. Second, it can help to reduce your carbon footprint. Third, it can extend the life of your water heater.

If you are looking for the best electric tankless water heater, it is important to choose a model with a high EF. A heater with an EF of 0.90 or higher is considered to be energy efficient.

Here are some examples of energy-efficient tankless water heaters:

  • Rheem RTEX-18 18 kW Electric Tankless Water Heater (EF: 0.93)
  • Stiebel Eltron Tempra Plus 24 kW Electric Tankless Water Heater (EF: 0.94)
  • Bosch Tronic 3000 T 24 kW Electric Tankless Water Heater (EF: 0.95)

By choosing an energy-efficient tankless water heater, you can save money, reduce your carbon footprint, and extend the life of your water heater.

3. Size

The size of a tankless water heater is an important consideration, especially if you have limited space. Tankless water heaters are much smaller than traditional water heaters, so they can be installed in tight spaces, such as under a sink or in a closet. However, it is important to make sure that the heater you choose is the right size for your home. If the heater is too small, it will not be able to meet the demand for hot water in your home. If the heater is too large, it will be inefficient and waste energy.

  • Hot water demand: The size of the tankless water heater you need will depend on the hot water demand in your home. Factors to consider include the number of people in your household, the number of hot water appliances you use, and the size of your home.
  • Flow rate: The flow rate of a tankless water heater is measured in gallons per minute (GPM). The higher the flow rate, the more hot water the heater can deliver. You’ll need to choose a heater with a flow rate that is high enough to meet the demand for hot water in your home.
  • Energy efficiency: The energy efficiency of a tankless water heater is measured by its Energy Factor (EF). The higher the EF, the more efficient the heater is. Look for a heater with an EF of at least 0.90.

By considering these factors, you can choose the right size tankless water heater for your home. A properly sized heater will provide you with a reliable supply of hot water while also saving you money on your energy bills.

4. Warranty

When choosing the best electric tankless water heater, it is important to consider the warranty. A good warranty will protect you from costly repairs in the event that the heater breaks down. Look for a heater with a warranty of at least 10 years.

  • Peace of mind: A long warranty gives you peace of mind knowing that you are protected from unexpected repair costs.
  • Quality assurance: A long warranty indicates that the manufacturer is confident in the quality of their product.
  • Extended lifespan: A long warranty can help to extend the lifespan of your water heater. If the heater breaks down during the warranty period, you can have it repaired or replaced for free.
  • Higher resale value: A water heater with a long warranty is more likely to have a higher resale value.

By choosing a tankless water heater with a long warranty, you can protect yourself from costly repairs and extend the lifespan of your water heater.

5. Price

When considering the price of a tankless water heater, it’s crucial to evaluate it in the context of its long-term benefits. While the upfront cost may be higher compared to traditional water heaters, tankless models offer substantial energy savings over time. This cost-saving potential makes tankless water heaters a financially viable option in the long run.

  • Energy Efficiency: Tankless water heaters operate on-demand, heating water only when needed. This eliminates standby energy losses associated with traditional water heaters that continuously maintain a reservoir of hot water. The high energy efficiency of tankless water heaters translates into lower energy bills, especially in areas with high energy costs.
  • Lifespan and Durability: Tankless water heaters typically have a longer lifespan compared to traditional models. Their compact design and lack of a storage tank make them less prone to corrosion and other issues that can shorten the lifespan of traditional water heaters. The extended lifespan of tankless water heaters further contributes to their overall value and return on investment.
  • Environmental Impact: The energy efficiency of tankless water heaters not only reduces energy costs but also contributes to environmental sustainability. By consuming less energy, tankless water heaters reduce greenhouse gas emissions and contribute to a cleaner environment.
  • Government Incentives: In some regions, government incentives and rebates are available for the installation of energy-efficient appliances, including tankless water heaters. These incentives can further offset the upfront cost and make tankless water heaters even more cost-effective.

In conclusion, while the price of tankless water heaters may be higher initially, their long-term energy savings, extended lifespan, positive environmental impact, and potential government incentives make them a worthwhile investment for homeowners seeking energy efficiency and cost savings in their water heating systems.
