What temperature should my tankless water heater be set at?

You’ll want to shoot for 100-115 degrees Fahrenheit for your water to be heated. If your groundwater temperature is 60 degrees and you want your shower at 110 degrees, that’s going to be a 50-degree rise.

What is tankless water heater temperature rise?

Temperature rise is the difference between the hot-water temperature you desire and the temperature of inflowing water. The flow rate of a tankless water heater (no matter its size) is the maximum GPM of hot water that it can supply on-demand by factoring the temperature rise.

Why is my tankless water heater not getting hot?

The Air Supply or Exhaust Is Blocked At times, your exhaust or air supply might get blocked, which can cause your tankless water heater to stop heating. Many water heaters will automatically shut off as a way to protect the appliance and help prevent other safety hazards that could result.
