GEOEXCHANGE / GEOTHERMAL HEATING AND COOLING SYSTEM INSPECTIONS AND ANALYSIS
As geoexchange becomes more popular, many installation companies are jumping on board. Unfortunately many are not qualified and customers get saddled with systems that are often improperly designed, not installed responsibly, and thus are never properly commissioned, costing the home owners thousands of dollars in inspections and re-work.
exchangenergy has been asked to inspect and repair flawed geo systems, and in every case has been able to identify and repair deficiencies that result in a system that functions properly.
To arrange an inspection of your Geo system, please contact us.
Example #1 - "How Did They Flush?" : This installer put in undersized flush ports that are too small to properly remove air and debris from the system. Air trapped in the ground loop prevented proper circulation and the system didn't work. They also used an old auto tire to mount equipment on!
Example #2 - "Flow Meter?": This contractor did not buy the proper J-tube flow meter for the QT and instead installed PT ports (the brass fittings in the upper left hand corner) to "measure the flow". Testing showed the flow was half of specified value and the system did not work.
Example #3 - "Two Things Wrong": This controls technician did very neat work, however, the transformer is over 100va which means that the brown LVT wire is too small and not allowed without mechanical protection (class one). The controller is a low-limit control which shuts the system down when the under-sized slinky loop gets too cold (see our blog for more about slinky loops).
Example #4 - "A Fusion Joint": Clearly, this carelessly fused joint was restricting flow. We cut it out and replaced it with bigger pipe and a smaller pump.
Example #5 - "A Pump The Wrong Way": This pump is mounted in the ONLY direction the manufacturer does not allow.
