Key changes proposed by EPA include:
- New requirements for
water-to-water heat pumps
- More stringent efficiency levels
for water-to-air and direct exchange systems
- Third-party
certification by AHRI (or other organizations as approved by EPA) for all
Energy Star qualified products effective Aug. 1, 2010
- Requirement to offer rather than automatically include a means to provide domestic water heating through the use of a desuperheater, integrated demand water heater, or stand-alone demand water heating system
