Welcome to ECONAR® Energy Systems
Manufacturer of GeoSource® Geothermal Heat Pumps
ECONAR has been producing GeoSource geothermal heat pumps in Minnesota
for a quarter of a century. Minnesota’s cold winter climate has driven
the design of ECONAR’s heating and cooling equipment to what is known
as a “ColdClimate” geothermal heat pump. This cold climate
technology maximizes the energy savings available in heating dominated
regions without sacrificing comfort, thus making ECONAR the leader in
cold climate heat pump technology. Extremely efficient cooling,
dehumidification
and optional domestic hot water heating are also provided in one neatly
packaged system.
Residential and Commercial - Heating, Cooling and Hot
Water
GeoSource Heat Pumps can be used in residential or commercial applications.
Common geothermal applications include: homes, churches, banks, schools,
car washes, fish farms, ice rinks, swimming pools, restaurants, and anywhere
heating, cooling and hot water is required. Check out the variety of geothermal
applications presented as

fits your needs.
Safety and Performance Certified
Safety and comfort are both inherent to, and designed into ECONAR’s
geothermal heat pumps. Since the system runs completely on electrical
energy, your entire home will have the safety of being gas free. ECONAR,
through installation of its heat pumps, has contributed significantly
to the reduction of global warming through the elimination of fossil fuels
in many homes and businesses. All of ECONAR’s products are safety certified
and its heat pumps are performance certified by internationally
recognized third party testing laboratories.
How Geothermal Works
Geothermal can be used to providing heating or cooling services. In each
instance the process is similar.
Geothermal Heating
In the heating mode, the water circulating in the earth loop is
colder than the surrounding ground. This causes the water to absorb energy,
in the form of heat, from the earth. The
water carries this energy to the heat exchanger in the pump. In the
heat exchanger, refrigerant absorbs the heat energy from the water. The
water now leaves the heat exchanger at a colder temperature, and circulates
through the earth loop to pick up more energy.
The refrigerant gas, which contains energy gained from the earth loop,
travels from the heat exchanger to the compressor. In the compressor,
the refrigerant temperature rises to 160°. From the compressor,
the superheated refrigerant travels to the air heat exchanger. Here, the
heat pump's blower circulates air across the air coil, increasing the
temperature of the air, which is blown through ductwork to heat the home.
After refrigerant releases its heat energy to the air, it then flows to
the earth loop heat exchanger to start the cycle again.
Geothermal Cooling
In the cooling mode, the water circulating in the earth loop is warmer
than the surrounding ground. This causes the water to release energy,
in the form of heat, into the earth. The
water, now cooler from traveling through the ground now flows to the heat
exchanger in the heat pump. In the heat exchanger, hot refrigerant
gas from the compressor releases its heat into the water. This causes
the water to increase temperature, which it releases to the ground.
The refrigerant, which has released its heat energy and became a cold
liquid, now travels to the heat exchanger. Here the heat pump's blower
circulates warm, humid air across the cold air coil. The air is then
blown through ductwork to cool the home. The refrigerant in the air coil
picks up the heat energy from the air, and travels to the compressor.
When the refrigerant leaves the compressor, it then flows to the earth
loop heat exchanger to start the cycle again.
