Installation Placement

Equipment can be placed inside or outside of the home.

Installation Placement
Maximum Input BTU

The maximum amount of heat that the unit can produce. The amount delivered into the space will be the input minus the efficiency loss also know as the output. For example a 100000 btu furnace at 80% efficiency will give you 80000 out btus of heat. The same size furnace at 95% will give you 95000 btus of heat.

Maximum Input BTU
237000 BTU
Minimum Input BTU

The amount of heat produced by the unit at the lower stage of heat. Having two stages of heat will allow for more consistent operation and greater comfort in the home.

Minimum Input BTU
19000 BTU
Gallons Per Minute
9.8 GPM
Hot Water Capacity Range

The gallons per minute of hot water that the unit is rated to provide. The actual amount of hot water generated can vary depending on your ground water temperature.

Hot Water Capacity Range
0.6 - 9.8 GPM
Thermal Efficiency

The percentage of the heat generated by combustion that goes into heating. The remaining percentage goes out the flue. The higher the efficiency rating, the lower the cost of operation.
