Operating efficiency
Aquazone water source heat pump
(WSHP) units are designed for quality
and performance excellence over their
lifetime. Units offer standard cooling
EERs (energy efficiency ratios) up to
13.5 for boiler/tower systems and as
high as 21.3 for geothermal applica-
tions. Heating COPs (coefficients of
performance) are as high as 5.1,
among the highest in the industry.
