Water-to-Water Heat Pumps
Water-to-water heat pumps give the customer “the best of
both worlds,” geothermal heating and cooling, plus the ability to
enjoy the benefi ts of warm radiant fl oors. The ClimateMaster

TMW series water-to-water heat pumps provide hot
and/or chilled water. In most applications, the water-to-water unit
is connected to a buffer tank, where hot or chilled water is stored,
and the hydronic system components (radiant fl oor or fan coil
units) pull hot or chilled water from the tank. This “decouples” the
unit water fl ow rate from the hydronic system fl ow rates, giving
the designer the fl exibility of using as many heating/cooling zones as
desired. Radiant fl oor heating is known for its unequaled comfort
and energy savings; when coupled with geothermal technology, the
system is the ultimate in heating and cooling.
The THW Series is a heating only water-to-water heat pump. It is
unlike any other water-to-water heat pump on the market today.
The THW can deliver up to 145°F (63°C) leaving load water
temperature even at 32°F (0°C) entering source temperature.
The THW includes a built-in controller to control the unit and
circulating pumps. It even has an outdoor reset function to vary
the buffer tank set point depending on the outdoor temperature
to heat only as much as needed. The THW also has an optional
DHW mode for heating potable water.
In summary, with ClimateMaster’s broad equipment line, almost
any installation can include a geothermal heat pump. Forced air
heating and cooling, radiant fl oor heating, chilled water cooling, and
combinations of various systems provide customers with systems
customized to their specifi c needs. High value, high quality and
environmentally responsible products separate ClimateMaster
geothermal heat pumps from other heating and cooling systems.
