TEMPERATURE RISE CHART
The chart below illustrates the maximum flow rate and temperature rise that can be achieved for the different AH Models. Most people shower at a temperature of between 98F and 104F. The chart is based on a 240 volt input voltage and maximum flow rates are listed for various incoming water temperature levels. If your home or business has less than 240 volt power (208v), your maximum flow rate will be lower. Simply look up your incoming water temperature and desired flow rate to determine your model choice. Don't forget that incoming water temperature may change throughout the year depending on the season.
