Additional Information

VKIN - Product from China arrived at lab waiting for testing. NEEA soliciting funds to conduct the test. Test method to be similar to new DHP COP testing. 9/26/17

Product is available in the Northwest and North America in general. RTF issued a “Planning” status on the Tier 4 Sanden product but it is currently challenged by the cost effectiveness. NEEA staff plan to publish the Advanced Water Heater Specification qualified products list after the working group has a chance to review the reports.

The Sanden split-system CO2 water heater is now listed on the Advanced Water Heater qualified products list.
