WATER/GROUND SOURCE MODELS
APPLICATIONS:
The water/ground source heat pump
can be used for hydronic heating
and cooling applications. The IVS-
095-W model is for water source
applications and the IVS-095-WLB is
for ground source applications.
Hydronic Cooling Capacities:
(IVS-095-W Model)
Graphic: Ground source models are installed
indoors.
