What is the temperature of your incoming water? This will
help determine which unit you will work best for you. It is
called the ambient water temperature.
- You will need a meat thermometer or candy thermometer or
any thermometer that will measure down to zero degrees
Fahrenheit.
- Make sure you are not running any appliances such as
dishwasher or clothes washer.
- Go to your kitchen sink and turn on the the cold water and
let it run about a minute. Hold the end of the thermometer
into the cold water for another minute. This will tell you
what the ambient temperature of the water coming into your
house is.
In the northern climates of the US, it is normal for the
ambient temperature of the water to be between 42 and 54
degrees all year long. In the lower southern states or coastal
states it can be as much as 70 degrees.
