Current Eligibility for SDHW

• pre-retrofit evaluation performed prior to October 1, 2009– collectors that meet CSA F378 or equivalent, – regardless of capacity– Validation: collectors or systems

• Select collectors from the ‘Glazed Water Heating Solar Collectors – Flat Plate Collectors’ or ‘Glazed Water Heating Solar Collectors – Evacuated Tube and Concentrating Collectors’ sections of the List of Accepted Solar Collectors found at the ecoENERGY for Renewable Heat Web site: http://ecoaction.gc.ca/ecoenergy-ecoenergie/heat-chauffage/collectors-capteurs-eng.cfm

• pre-retrofit evaluation performed on or after October 1, 2009 – Systems that use CSA F378 or equivalent collectors AND– meet the 6 GJ minimum capacity requirement (as per CSA F379)– Validation: systems

• Multi-residential building– CSA 378 collectors – 3 Gj per residential unit– Divide by 6 Gj – whole number multiplied by $250 = eligible grant

• Systems used for more than DHW– Eligible

• System must comply with program requirement of:• System must provide domestic hot water

– Not eligible• Systems use for pools or systems used for space heating only

Systems

Systems

Determining System Capacity (MURB – other application)

• Option 1- if system is listed on CanmetENERGY Performance Directory of Solar Domestic Hot Water Systems

– use the Annual Performance Rating for the system

• Option 2- If collectors are used in a system that is listed on CanmetENERGY Performance Directory of Solar Domestic Hot Water Systems

– Estimated system capacity must be noted on client invoice

• Option 3- If option 1 or 2 does not apply, collectors must be part of the list of collectors from the ‘Glazed Water Heating Solar Collectors – Flat Plate Collectors’ or ‘Glazed Water Heating Solar Collectors – Evacuated Tube and Concentrating Collectors’ sections of the List of Accepted Solar Collectors found at the ecoENERGY for Renewable Heat Web site Collector used by system from table 1.2

– run a TRNSYS simulation to validate capacity

Future

• CSA 379 certification for systems– 2010

• CSA installation

• Energy Star – 7 Gj
