Tankless Hot Water Heater vs. Tank?

Check out more about each to decide which type of hot water heater is best for your home.

Most people know they have an option of either a Tankless Water Heater or a Traditional Water Heater for the water maintenance in their homes. However, most people don’t fully understand the difference between the two, and how to determine which one is best for their house.

To begin the process, you need to first identify how much water your house needs. Are you a family of 4, or is it just you and your dog? Next, you need to determine the ground water temperature in your area and figure out if you live in an extreme weather condition area or not.
