Maximum Water Side Pressure Drop	15 205 10 PSI
Optional Selections Below
Custom Water Flow Rate Optional	PPH GPM Check to allow flow rate to track firing rate. Enter the water flow rate ONLY if the flow rate will differ from the boiler capacity flow rate. This feature is for economizers used in a non-traditional installation such as process water heating. If your application is a typical boiler economizer arrangement then leave this cell blank and leave units on PPH.
Two-Stage Economizers Optional	Check to Select Two-Stage Economizer Unit Enter Second Stage Water Inlet Temperature PPH % Make-Up Enter Second Stage Water Flow Second Stage maximum Water Side Pressure Drop: 15 20 5 10 PSI Check to allow flow rate to track firing rate. Enter the water flow rate ONLY if the flow rate will differ from the boiler capacity flow rate. This feature is for economizers used in a non-traditional installation such as process water heating. If your application is a typical boiler economizer arrangement then leave this cell blank and leave units on PPH.
Condense-O-Mizer Optional	Select Condense-O-Mizer dedicated exernal condensing economizer with ID Fan.
Stacked Economizers Optional	Do Not Stack Units Double-Stack Units Triple-Stack Units Stacking economizers is a way of increasing heat recovery by placing two identical units inside of a common casing.
Targeted Flue Gas Exit Temperature Optional	Enter Target Gas Exit Temperature deg F Stay with Model Selected Increase Model Size If you need a unit to meet a specific flue gas exit temperature enter the value in the above data field and Bruce will manipulate various designs to come as close as possible.
Stainless Tube Override Optional	Override ON Override OFF By default units with deaerated water will be supplied with carbon steel tubes, all other applications and all Shorty units have stainless steel tubes. Should you wish to override the carbon steel tube selection for deaerated applications and utilize a stainless steel tube click the button above.

Manual Unit Selection / Bypass Bruce - For Experienced Boiler Technicians Only:
AutoPick ON
AutoPick OFF - Manual Selection below
Experienced boiler professionals may bypass Bruce's AutoPick software and manually select a maximum gas side pressure drop from the selection chart below. Just because a data page will be printed out means HeatSponge confirms that a manually selected unit will work on a given boiler. Excessive backpressure will seriously impact boiler operation.

This feature is also a very good way to compare the performance of a competitive unit to a HeatSponge. If you are comparing units and the competitive unit has a higher gas side pressure drop than our AutoPick selects use this feature to see how a HeatSponge would compare to the competitive selection. Some competitors will try to sell a smaller unit with an excessively high backpressure simply to offer a lower price.
Select Maximum Allowable Backpressure: 0.05 0.06 0.07 0.08 0.09 0.10 0.12 0.15 0.17 0.20 0.22 0.25 0.30 0.35 0.40 0.45 0.50 0.55 0.60 0.65 0.70 0.75 0.80 0.90 1.00 1.25 1.50 1.75

Flue Gas Mass Flow Calculation Override - For Experienced Boiler Technicians Only:
Experienced boiler professionals may custom select the flue gas mass flow rate. You must both enter the mass flow number to use as well as check the override checkbox.
Enter the custom mass flow rate in pph in this box
Bypass checkbox required

Final unit selection could be affected by other operational constraints. HeatSponge reviews all selections for accuracy prior to placement of any purchase order.
