Integrated water-space heating combination devices will be evaluated as if they were an instantaneous water heater with at least a 93.3 Annual Fuel Utilization Efficiency (AFUE) rating.(e)
Equipment efficiency requirements are based on either the listing by ENERGY STAR®, the directory of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), or other third-party certified list approved by the Director.(3)
Wastewater Heat Recovery Device is a device designed to recover thermal energy from household wastewater streams for the purpose of returning a portion of this energy to the dwelling’s domestic hot water system. Field performance data submitted to and approved by the department will be the basis for tax credit qualification. The following rules also apply:(a)
The system must meet all plumbing code requirements for vented double-wall heat exchangers;(b)
The system must not interfere with the proper operation of the dwelling’s wastewater system; and(c)
Energy recovered must be re-introduced into the dwelling’s hot water supply system.(4)
Sealed Duct Systems must meet the following requirements:(a)
Have all work must done by technician with a current or valid certification with Performance Tested Comfort System (PTCS), ACCA Quality Installation or approved by the department as equivalent.(b)
To apply for a sealed duct system tax credit, the following information must be submitted on the department approved application form:(A)
Certification that Bonneville Power Association’s Prescriptive Duct Sealing Specifications have been completed; and(B)
Itemized invoice identifying costs.(5)
Energy Recovery Ventilators (ERVs) are devices that provide balanced fresh air ventilation for homes with the ability to transfer energy from the outgoing air stream to the incoming air stream. ERVs must:(a)
Be tested, rated and certified through the Home Ventilating Institute (HVI) Division of the Air Movement and Control Association (AMCA) International, Inc., and listed in the HVI directory;(b)
Be capable of at least 30 percent Latent Recovery/Moisture Transfer (LRMT) at 32 degrees F when operating on the lowest fan speed. LRMT is the moisture recovered to the ventilation supply air stream divided by moisture being exhausted, corrected for cross leakage, if any. For example, LRMT = 0 would indicate that no exhausting moisture is recovered for the incoming supply air stream. LRMT = 1 would indicate that all exhausting moisture is recovered for the incoming supply air stream;(c)
Have a maximum EUI of 1.10 watts/cfm at the lowest fan speed for which performance data is published in the HVI directory; and(d)
Have a minimum Sensible Recovery Efficiency (SRE) of:(A)
75 percent at 32°F/0°C when operating at the lowest fan speed; and(B)
67 percent at 32°F/0°C when operating at the highest fan speed.(6)
Heat Recovery Ventilators (HRVs) are devices that provide balanced fresh air ventilation for homes with the ability to transfer energy from the outgoing air stream to the incoming air stream. HRVs must:(a)
Be tested, rated and certified through the Home Ventilating Institute (HVI) Division of the Air Movement and Control Association (AMCA) International, Inc., and listed in the HVI directory;(b)
Have a maximum EUI of 1.10 watts/cfm at the lowest fan speed for which performance data is published in the HVI directory; and(c)
Have a minimum Sensible Recovery Efficiency (SRE) of:(A)
75 percent at 32°F/0°C when operating at the lowest fan speed; and(B)
67 percent at 32°F/0°C when operating at the highest fan speed.(7)
High Efficiency Air Source Ducted Heat Pump Systems are devices that use heat pump technology to create heated or cooled air, for distribution through ductwork. An air source ducted heat pump device consists of one or more factory-made assemblies which normally include an indoor conditioning coil, compressor and outdoor coil. These devices must:(a)
Have all work done by technician with a current or valid certification with Performance Tested Comfort System (PTCS), Proctor Engineering CheckMe!, ACCA Quality Installation or approved by the department as equivalent;(b)
Be tested and rated in accordance with the USDOE Appendix M test procedure in effect at the time these rules are adopted, and be certified by, and be listed in the directory of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) that is in effect at the time these rules are adopted;(c)
Consist of a matched outdoor unit and indoor unit (air handler and coil or furnace and coil), as tested, rated and listed in the AHRI directory;(d)
Have a minimum USDOE Region IV HSPF rating of 9.5 or greater; and(e)
Systems must be installed and attested to the protocols of tested and serviced as needed to confirm correct refrigerant charge and air flow by a technician authorized by the department and by an approved Performance Tested Comfort System (PTCS), Proctor Engineering CheckMe!, ACCA Quality Installation or approved by the department as equivalent.(8)
High Efficiency Furnace Systems are devices that heat and distribute air through the dwelling using a system of ductwork. A high efficiency furnace system is determined by its Annual Fuel Utilization Efficiency, (AFUE). These devices must:(a)

High Efficiency Ductless Air Source Heat Pump Systems are air-source heat pumps consisting of an outdoor unit connected directly to one or more indoor units through which conditioned air is delivered directly to the room or zone of a home rather than through a central furnace. These devices must:(a)
