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.
