Do electric tankless water heaters work in the midwest?

The problem with electric tankless water heaters is when you have a temperature rise over 70 degrees. In the Kansas City area, we have several weeks out of the year where the incoming water supply is just to cold for an electric tankless to keep up.

When reading online reviews of tankless water heaters online, be sure to factor in the areas with warmer climates will have a much higher flow rate than in cooler climates.

What is the temperature rise?

The temperature rise is the difference in temperature from the water that feeds into the water heater and the temperature is must be heated to. In Kansas City the temperature rise is usually 70 – 80 degrees.
