Consulting with a professional installer can also provide valuable insights and help you determine the most cost-effective options for your specific situation.
Analyzing the Energy Efficiency and Cost-Savings of Tankless Water Heaters
When considering the installation of a tankless water heater, it is important to evaluate its energy efficiency and potential cost savings. Tankless water heaters are designed to provide hot water on demand, which eliminates the energy consumption associated with constantly heating and storing water in a traditional storage tank. This results in higher energy efficiency and lower utility bills over time.
The energy factor (EF) is a key metric used to measure the efficiency of tankless water heaters. The EF represents the percentage of input energy that is converted into hot water. Typically, tankless water heaters have higher EF ratings compared to conventional storage tank water heaters. This means that a larger proportion of the energy used is directly converted into heat, resulting in less wasted energy.
To further illustrate the energy savings provided by tankless water heaters, let's consider an example:
Annual Operating Cost Electric Tankless Water Heater $75 - $300 Gas Tankless Water Heater $175 - $500
As shown in the table, the annual operating cost of electric tankless water heaters generally ranges from $75 to $300, while gas tankless water heaters have a higher range of $175 to $500. These estimates are based on factors such as the energy consumption of the unit and the cost of energy.
By choosing a tankless water heater with a high EF rating and comparing the potential energy savings to the cost of the unit and installation, homeowners can make informed decisions about investing in energy-efficient hot water solutions that align with their budget and environmental goals.
Finding the Right Size Tankless Water Heater
Choosing the right size tankless water heater is crucial to ensure a sufficient supply of hot water for your household needs. The size of the tankless water heater is determined by the flow rate (GPM) and the temperature rise (ΔT) required to reach the desired hot water temperature. By considering these factors, you can select a tankless water heater that meets your specific requirements and avoids any issues with inadequate hot water.
Flow Rate
The flow rate, measured in gallons per minute (GPM), indicates the maximum amount of hot water that the tankless water heater can provide at a given time. To determine the appropriate flow rate for your home, consider the number of appliances and fixtures that will be using hot water simultaneously. For example, a shower typically requires a flow rate of around 2-2.5 GPM, while a dishwasher may require 1-1.5 GPM. By calculating the total GPM required, you can choose a tankless water heater with the appropriate flow rate.
Temperature Rise
The temperature rise (ΔT) refers to the increase in water temperature required to reach the desired hot water temperature. Depending on the groundwater temperature in your area and the desired hot water temperature, the temperature rise can vary. For example, if the groundwater temperature is 60°F and you want your hot water to reach 120°F, the temperature rise would be 60°F. It's essential to consider the temperature rise when selecting a tankless water heater to ensure it can provide the necessary heating capacity.
Size Selection Example
Let's consider an example to illustrate the process of selecting the right size tankless water heater. Suppose you have a home with two bathrooms, a kitchen, and a laundry room. Assuming that you may have a shower running in one bathroom (2 GPM), a dishwasher in the kitchen (1 GPM), and a washing machine in the laundry room (1.5 GPM) simultaneously, the total required flow rate would be 4.5 GPM. Additionally, suppose the desired hot water temperature is 120°F, and the groundwater temperature is 60°F, resulting in a temperature rise of 60°F. Based on these factors, you would need to select a tankless water heater that can provide a flow rate of at least 4.5 GPM with a temperature rise of 60°F to meet your hot water demands adequately.
Number of Bathrooms Number of Appliances/Fixtures Required Flow Rate (GPM) 2 Shower 2 Dishwasher 1 Washing Machine 1.5 Total Required Flow Rate 4.5

Pairing a tankless water heater with solar panels can further enhance the environmental benefits. By harnessing the power of the sun, solar panels provide clean and renewable energy to heat water, reducing reliance on fossil fuels. This combination contributes to even greater energy efficiency and sustainability.
Maintenance and Longevity of Tankless Water Heaters
Regular maintenance plays a crucial role in ensuring the optimal performance and longevity of tankless water heaters. By following a few simple steps, you can keep your system running efficiently for years to come. One important maintenance task is descaling, which involves removing mineral buildup from the heat exchanger. This can be done using a descaling solution recommended by the manufacturer. Performing regular checks for leaks and ensuring proper ventilation are also essential for preventing any potential issues.
Tankless water heaters generally have a longer lifespan compared to traditional storage tank water heaters. With proper care and maintenance, tankless models can last up to 20 years or more. This longevity is due to their durable construction and the absence of a storage tank, which eliminates the risk of tank corrosion and leakage. However, it's important to note that the lifespan can vary depending on factors such as water quality, usage patterns, and the specific model of the tankless water heater.
When it comes to maintaining your tankless water heater, it's always a good idea to refer to the manufacturer's recommended maintenance guidelines. These guidelines will provide you with specific instructions tailored to your specific model. By following these guidelines and performing regular maintenance tasks, you can extend the life of your tankless water heater and ensure it continues to provide efficient hot water for many years to come.
