FAQ, GENERAL INFORMATION & OPERATING TIPS
Is maintenance required for the earth loop?
No regular maintenance is required. However, if you notice air noise within the piping or if your loop is ever damaged by
excavation, contact your WaterFurnace dealer.
Should I use the Continuous Fan mode?
In Continuous Fan mode, your blower operates constantly, even when the unit is not heating or cooling. The
Continuous Fan mode (selected on your thermostat) can reduce hot spots or cold spots throughout the home by
constantly mixing the air. Indoor air quality is also improved due to continuous filtration. Using Continuous Fan mode in
units equipped with ECM blowers is very inexpensive. However, using Continuous Fan mode in units equipped with PSC
blowers is considerably more expensive and will noticeably increase operating costs.
What about units using well water?
An adequate water supply to the unit is very important. Do not let anyone disrupt the water supply by rerouting the supply
line or tapping into it without first checking with your WaterFurnace dealer. If the well pumping system requires service or
is inoperable, your unit should be turned off or placed into emergency heat until an adequate water supply is restored.
Depending on the water quality, some maintenance is usually required with a well water system. Without scheduled
checkups, minerals and other particles in the water may eventually begin to clog the heat exchanger in the unit. When
this happens, the efficiency and capacity of the unit is decreased, eventually to the point where failure may occur.
To minimize the potential of this happening, a heat exchanger cleaning schedule should be established with your dealer.
The frequency will depend on the specific quality of your well water. Some homeowners find that they can go a few
years between cleanings while others may need to have the heat exchanger cleaned yearly. In order to achieve optimum
performance, energy savings and long system life, it is necessary to have your dealer perform this service as needed.
Remember — preventive maintenance is less expensive than replacing major components.
The cleaning procedure requires special equipment and chemicals. Therefore, do not attempt to clean the heat
exchanger yourself.
