Tankless water heaters use heating coils to heat the water when you need it. Because they don’t keep a tank of water at a certain temperature, tankless water heaters, especially natural gas ones, are more energy efficient than tank water heaters. 

But they can provide only a certain amount of hot water per minute. So a major consideration is how many gallons per minute (GPM) your household might need and whether you will use water in more than one way at once. The higher the GPM rating, the more water the heater can produce. If you use water in multiple ways at once–showering and washing dishes, for example–then a tank water heater may be a better choice.

Common problems with tankless water heaters that lead to repairs include mineral buildup, corrosion, excessive demand, and venting problems. Hard water can cause mineral buildup, leading to inefficiency or even damage it. Corrosion, trying to use more hot water than the heater can produce, and improper venting can all trigger the water heater’s computer to shut down entirely.
