Introduction to Tankless Water Heaters: Best Electric Tankless Water Heater 2021
Tankless water heaters are revolutionizing the way we heat water, offering a more efficient and convenient alternative to traditional tank models. These innovative systems provide hot water on demand, eliminating the need to heat and store large volumes of water. This efficiency translates to significant cost savings and a smaller environmental footprint. This overview delves into the core concepts of tankless technology, comparing it to traditional tank systems, and highlighting its advantages and disadvantages.The fundamental difference lies in how hot water is produced.
Tank water heaters heat and store a large volume of water in a tank. Tankless units, conversely, heat water directly as it’s needed, eliminating the energy waste associated with maintaining a large volume of heated water at all times. This instantaneous heating method is the heart of their efficiency.
Key Features and Benefits
Tankless water heaters offer a range of advantages, making them a compelling choice for modern homes and businesses. These include: superior energy efficiency, reduced water waste, and enhanced convenience. They eliminate the standby losses associated with traditional tank systems, which continuously heat water in the tank. This leads to considerable savings on energy bills.
Comparison of Tankless and Traditional Water Heaters
The table below highlights the key differences between tankless and traditional tank water heaters, focusing on energy efficiency, cost, and installation complexity.
| Feature | Tankless | Traditional |
|---|---|---|
| Energy Efficiency | Generally more efficient, heating water only when needed. Can save 20-60% on energy costs compared to a traditional tank water heater. This significant efficiency gain comes from eliminating the energy lost to maintaining a large volume of hot water. | Less efficient, constantly heating water in the tank. Energy is lost through heat dissipation and maintaining the water temperature. |
| Cost | Initial cost tends to be higher than traditional tank models. However, the long-term savings in energy costs often offset this initial investment within a few years, particularly in areas with high energy rates. | Lower initial cost but higher ongoing energy costs due to constant heating. |
| Installation | Installation can sometimes be more complex, requiring careful plumbing considerations and potentially more space for venting. Professional installation is recommended for optimal performance. | Installation is generally straightforward, requiring less specialized expertise. |

However, careful consideration of key factors is paramount to achieving optimal performance and cost-effectiveness.
Water Pressure Requirements
Adequate water pressure is essential for tankless water heaters to function effectively. Insufficient pressure can lead to reduced hot water flow or even complete failure to deliver hot water. The minimum pressure required often varies depending on the specific model and the design of the water heater.
BTU Output and Household Water Usage
Determining the appropriate BTU (British Thermal Unit) output is critical. This capacity must match your household’s hot water usage patterns. Consider peak demand times and the number of people using hot water simultaneously. Overestimating capacity leads to unnecessary expenses, while underestimating it may result in insufficient hot water supply during peak demand periods. For instance, a family of four with multiple showers and frequent hot water usage for cooking might require a higher BTU output than a smaller household.
A professional evaluation can help determine the precise needs of a particular home.
Fuel Type Comparison (Gas vs. Electric)
Tankless water heaters are available in both gas and electric models. Gas units often offer higher efficiency ratings and lower initial costs, while electric models provide greater control and flexibility. The choice between gas and electric will hinge on local utility rates, gas availability, and personal preferences. Gas models may be a more cost-effective option in areas with favorable gas pricing, while electric models may be preferable in locations with limited gas infrastructure.
Technology Comparison (Heat Exchangers and Burners)
Different tankless water heater models utilize various technologies. The most common include heat exchangers and burners. Heat exchangers transfer heat from the fuel source to the water, while burners directly combust fuel to heat the water. Understanding the differences in these technologies is crucial. Heat exchangers often deliver a more stable flow of hot water, while burners might offer slightly higher output for high-demand situations.
Comparing the specific features of different models is essential to selecting the best technology for your requirements.

Tankless water heaters, while often perceived as a higher initial investment, can actually lead to significant long-term savings, thanks to their energy efficiency and potential for rebates. Understanding the upfront costs, long-term savings, and energy efficiency ratings is key to making an informed decision.
Upfront Costs vs. Long-Term Savings
Tankless water heaters often have a higher initial purchase price compared to traditional tank models. This difference stems from the advanced technology and components within tankless units. However, the long-term savings can often outweigh this initial investment. Consider this: a tankless water heater might cost $2,500, whereas a traditional tank model might be $1,000. But over time, the energy efficiency of a tankless unit can lead to substantial savings on utility bills.
Energy Efficiency Ratings and Utility Bills
Energy efficiency is a crucial factor in determining the long-term cost-effectiveness of a water heater. Tankless water heaters typically boast high efficiency ratings, often expressed as energy factor (EF) or annual fuel utilization efficiency (AFUE) ratings. A higher rating translates to lower energy consumption and, consequently, lower monthly utility bills. For instance, a tankless unit with an EF of 0.90 will use less energy than one with an EF of 0.80, resulting in significant savings over the lifetime of the unit.
This translates directly into lower monthly energy bills for hot water.
Potential Cost Savings Over Time
The long-term cost savings from a tankless water heater can be substantial. Lower energy consumption means lower utility bills each month. Over the life of the water heater, the cumulative savings can significantly exceed the initial investment difference. For example, a household using 100 gallons of hot water daily could see a substantial reduction in energy costs, translating into hundreds, perhaps even thousands, of dollars saved over the lifetime of the water heater.
Rebates and Incentives
Rebates and incentives can significantly reduce the overall cost of installing a tankless water heater. Many utility companies and government programs offer rebates for energy-efficient appliances. These rebates can offset the higher upfront cost, making tankless water heaters more accessible and cost-effective. Research local programs and check for current rebates and incentives.
