DEFINE YOUR NEED AND SIZE THE HEATER TO SOLVE THE PROBLEM

You probably navigated to this site because you need an electric "fluid" heater to solve a problem. Before we can determine what heater you need you must obtain the following information.

1. Temperature of your incoming water/fluid on the coldest day of the year.

2. Temperature of the water/fluid you want to use.

3. How much water/fluid you need per minute or hour. 

Once the above information is available you can select the size heater you need from the recovery chart below by doing the following;

1. Subtract the inbound fluid temperature from the temperature you need to obtain "Temperature Rise"

2. Then, go to the appropriate "temperature rise" column on the recovery chart.

3. Move down the chart to the find the size heater you need based on your hourly or per minute usage.

FOR EXAMPLE:

1. Let's say you need 5 gallons per minute at 150 degrees and you are using ground water in the Midwest where the inbound water could be as cold as 40 degrees in January. You would need an 81KW unit to satisfy your requirements. (110 degree rise at 5 gallons per minute.)

To do the calculation on your own without the chart, you would use the algebraic formulas shown below. We use the same data from above.
