EER is boosted up to 12% over the existing ClassMate HE for integrated part-load values up to 16.1. The CF microchannel evaporator coil replaces a much larger coil traditionally used in these types of systems.
New to the lineup are small floor-mount units (less than 24” high and 30” wide) in 9,000, 12,000 and 15,000 Btu/hr. Also new are the 7,000 Btu/hr. compact-cassette and slim-duct models.
The 16 SEER heat pumps feature a full metal jacket, polyester urethane finish, copper tube and aluminum fin coils. A high-pressure switch protects against excessively high system pressures and a liquid line filter-drier is included for field installation.
Exceeding ASHRAE 90.1 efficiencies, it comes in a two-piece chassis/cabinet design. It has a 20° F to 120° F range of operation and an EarthPure (HVC-410A) zero ozone depletion refrigerant.
In past columns, we’ve discussed geothermal water-to-water heat pumps and air-to-water heat pumps via hydronic heat sources. Both can be a great match to low-temperature hydronic distribution systems.
A. O. Smith launches its newest hybrid electric water heater, the Voltex 50-gal. heat pump as an extension of the existing Voltex line.
The Stiebel Eltron Accelera 300 heat pump water heater can extract up to 80% of its energy requirements from the energy around it.
WaterFurnace introduces the 5 Series 502W12 high-temperature hydronic heat pump. Capable of 150° F water output
