Number of Fixtures
The number of fixtures that the tankless water heater can supply simultaneously is another critical factor. You'll want to ensure that the water heater can handle the demand of all the fixtures in your home, providing hot water whenever you need it.
Factor Consideration Fuel Type Propane, natural gas, or electric? Power Output Choose a unit that matches your heating needs. Flow Rate Determine the gallons per minute (GPM) required. Number of Fixtures Ensure the water heater can supply all your fixtures simultaneously.

Non-condensing tankless water heaters, on the other hand, do not have a secondary heat exchanger and do not recover heat from the exhaust gases. While they are still energy-efficient compared to traditional tank-style water heaters, non-condensing models may have slightly lower efficiency ratings. These units are often more affordable and may be suitable for homes with lower hot water demands.
In summary, when choosing a tankless water heater, consider the type that best suits your needs: gas or electric, indoor or outdoor, condensing or non-condensing. Each type offers its own advantages and considerations, so take the time to evaluate your hot water requirements and choose the right tankless water heater for your home.
Choosing the Right Size Tankless Water Heater
When selecting a tankless water heater, it is crucial to choose the right size to meet your hot water needs.
