Geothermal systems are the most efficient heating and cooling systems available and because they have few moving parts, are not prone to a lot of repair. However, one major concern regarding repairs to geothermal system is leaking from the ground loop. The good news is that geothermal systems are not prone to leaking; secondly, should a leak develop with your geothermal ground loop, there is a way technicians can detect it fairly easily.
The first reason geothermal systems aren’t prone to developing leaks is that the tubing is very durable: it is made of a high density polyethylene material that is extremely durable but also allows heat to transfer easily. The average lifespan of a ground loop is 25-50 years, so it’s safe to say that ground loops are made to withstand the elements. Additionally, all joints are fused, strengthening the loop throughout.
In the case of a geothermal loop leak, the entire loop doesn’t have to be extracted from your yard. The process for detecting a leak in a geothermal loop is quite simple: a technician will inject dye into the loop and wait for it to circulate; once the dye reaches the leak, the solution from the loop, with the dye, bubbles to the surface of your yard. A couple of days after injecting the dye, the technician will inspect your yard for the dye so he/she knows where to dig. Once the dye is found, he/she will dig down, seal the leak, and re-cover the loop.
If you have concerns about your geothermal loop leaking, it’s good to be aware of the signs that can indicate a leak has developed:
- Soggy/wet spots in your yard where loop is buried
- Noticeable decrease in performance
- Problems with the heat pump
