Smart Heater Bypass Kit
*Certified by a third party test lab and communicated to SCAQMD for Rule 1146.2
*Savings amount based on lab testing conducted using MasterTemp 400® heater in conjunction with IntelliFlo® VSF Pump and Bypass Kit, which includes IntelliValve® controlled
by heater. Test Conditions: Pump flow rate: 50gpm. Pump run time: 3000 hours/yr. Heater run time: 100 hours/yr. Electrical Cost: $0.21 per kWh. System TDH: Heater and Bypass
Kit added to Standardized “Curve C” System Curve performance data as per California Energy Commission Title 20 Appliance Efficiency Regulations. Test conditions assume
pump flow rate of 50gpm and Constant Flow operation utilizing a lower motor RPM when flow is bypassing the heater due to lower system TDH. Actual performance and any
subsequent energy consumption/savings are dependent upon various characteristics of the plumbing system, including but not limited to, pipe size, pipe lengths, filter type, fittings,
system design, equipment run time/settings and more.
