About two years ago I built a new home and installed a Bard Geothermal Heat Pump. I am using my well as the source for water and using my pond for the dump of water. The system works great! My bills from my utility company have been lower than 50.00 per month in the coldest month here in Michigan. Im heating a home 2800 sq.ft. However, I do have a couple concers and would like some advice or opinions to kind of ease my mind.
As with any well you have the risk of it going dry so this is always been a concern. My well guy said I was pumping 12-18 gallons a minute but I have read a couple articles saying the geothermal unit uses like 2500 gallons a day. Is that true?
Also, my well supplies water for daily use. Showers, laundry, cleaning. This means my well pump kicks on every time the Geo starts up or when there is a lack of pressure. Does the well pump kick on everytime the pressure tank kicks on? This is also a concern because will I need to be buying a new well pump every five years?
Since I have an open loop system do I need to flush the pump for cleaning? Im concerned about build up or sediment.
Please let me know what you think regarding my system. Because of all the water and well and concerns I have I was researching a pond loop. Let me know what you think.
