Performance Data
ARI-ISO (WLHP/GLHP)
Table P1: ARI-ISO WLHP and GLHP Performance
Rated in accordance with ISO Standard 13256-1: 1998 (Water Loop Heat Pumps and Ground Loop
Heat Pumps).
Certified conditions are 86°F EWT, 80.6°F DB/66.2°F WB EAT in cooling and 68°F EWT, 68°F DB/59°F
WB EAT in heating. Data shown is for application performance only, as these conditions are typical
for WSHP systems.
Models with capacities greater than 135,000 BTUH are not included in the ARI water-to-air and
brine-to-air heat pump certification program.
