FAQ, GENERAL INFORMATION & OPERATING TIPS
If my system includes an auxiliary heater, what does it do and why was it used?
Your system may include an auxiliary heater (mounted either internally or externally depending on the model) which is
used for two purposes:
• To supply back-up heat during cold outdoor temperatures.
• To provide emergency heat if the unit’s compressor fails.
Generally, dealers will size the geothermal unit to provide the majority of the heating requirements down to a certain
outdoor air temperature. When conditions exist that require more capacity than the geothermal unit is sized to deliver,
the auxiliary heater engages to assist the geothermal unit, (which continues to work). If the unit were to be sized to
provide 100% of the heat on the coldest day, the unit would be “oversized” every day that isn’t the coldest day of the
year. Plus, the initial cost of installation could have been significantly higher for a larger unit and additional loop. Your
dealer has determined the right combination/size of equipment that makes economic sense in terms of installation cost
and operation.
The other reason for the auxiliary heater is to provide heating in the event of a compressor failure. Switching to
Emergency Heat mode on your thermostat will provide the home with a source of heat until the compressor is replaced.
Does my unit heat water?
Some units are equipped with a “hot water assist” component. Depending on conditions, this component can preheat
water by raising the temperature by as much as 2°-10° F and then deliver it to your water heater using a small pump. The
"hot water assist" is not designed to heat water like your water heater. However, a unit equipped with a "hot water assist"
heats water much more efficiently than your water heater and can provide energy savings whenever the hot water assist
is operating. The amount of hot water generated by the "hot water assist" is a function of how long the unit is running
and what mode it is in.
What if I run out of hot water?
Units equipped with hot water generators provide only supplemental water heating. Your water heater will operate if the
unit is not heating the water adequately. If you run out of hot water, it is most likely a problem with the water heater and
not the geothermal unit.
How do I know where my earth loop is located?
Earth loops can be installed in several configurations depending on the space available. The company who installed your
loop should provide you with a layout of the loop field with measurements & locations of each circuit length based on
fixed locations (e.g. the corners of the house). Some loop contractors install metallic tape or tracer wire in the trench
to assist in future locating. Keep this document and refer to it before doing any digging or excavating in the area of the
loop. It is also recommended that you sketch out the loop location.
