Top Considerations When Buying a Tankless Water Heater

While traditional water heaters have been an economical choice for many homeowners, they come with several drawbacks that lead to unwanted expenses and headaches in the long run. That is why as your expert in water heater repair in Murrieta, CA, A.M. Plumbing & Rooter, we recommend switching to tankless water heaters. They last longer and are more energy-efficient than other models, making them worth the investment.

Before buying a tankless unit, you will want to do research and ensure it meets your needs. To help you make an informed decision, consider the following:


While tankless water heaters are easier to maintain than their traditional counterparts, they still need regular care. The maintenance requirements for tankless units mostly depend on their fuel source. Gas-powered water heaters need more attention to ensure safe fuel combustion and remove scale buildup. On the other hand, electric-powered units only require occasional cleaning. Nevertheless, you can rely on our team for preventative water heater services to keep your unit in peak condition.


When sizing a tankless hot water heater, you should identify the ideal flow rate and the temperature rise for its application. You can calculate the flow rate by listing the hot water outlets you use during the peak hours of your day and adding up their gallons per minute (GPM). For the temperature rise, subtract your groundwater temperature from your desired water temperature. You can count on our team to do the necessary calculations and find the best size for your tankless unit.

Energy Efficiency

Consider the energy efficiency of the tankless water heater. The energy factor (EF) is based on recovery efficiency, which indicates how well the unit transfers heat from the energy source to the water, and cycling losses, which refers to the heat loss as water goes through the inlet and outlet pipes. The higher the EF, the more energy efficient the water heater is.
