Extra Efficiency model GSWD Ground-Source Heat Pump

to Ground Source Heat Pumps
 Radiant
floor heating systems in residential applications can decrease cost
while increasing comfort for the owner or occupant. A ground-source
water-to-water heat pump and radiant floor system utilizes the earth's
energy to move heat from within the ground, into your home. Similar
to a small reverse cycle chiller, a water-to-water model GSWD, heat
pump contains a source-side and a load side water-to-refrigerant
heat exchanger. During the refrigeration cycle, heat is transferred
from the source-side heat exchanger to the load-side heat exchanger,
or vice-versa. The source for the water-to-water-heat pump may be
connected to a ground-source (geothermal) loop system, allowing
the system to economically provide conditioned fluid (hot or cold)
to a mechanical device such as radiant floor heating, hydronic fan
coils, or fresh air ventilation systems.
