Most of the industry use ECM motors in high-efficiency heating and cooling systems. We have found them to be very reliable. This video is designed to help technicians troubleshoot an ECM motor if a failed motor is suspected. As always, remember a failed component is the symptom, not the cause of the failure. Thanks for watching Geothermal University!
In this video, we’re going to discuss installation, setup, features and benefits of the Geo-Flo variable speed flow center using the Grundfos Magna Geo 32-140 pump. The Geo-Flow Installation operation Manual or IOM is on Geothermal University along with this video. We recommend having the publication at hand while watching.
A leading HVAC manufacturer found that nearly 30% of all "returned as failed" compressor were misdiagnosed and still working. A leading compressor manufacturer reported their analysis showed less than 5% failed because of a manufacturing defect. It's important to remember, the compressor failure is a symptom, not the failure. If the system is not thoroughly checked, the replacement compressor will also fail. Thanks for watching!
Welcome to Geothermal University online training by Enertech Global. Antifreeze levels are crucial for reliable operation of geothermal systems in cold climates. This video shows how to calculate antifreeze in gallons for closed loop geothermal systems. Be sure to download the attached worksheet (Excel file) to help with your calculations. Thanks for watching!
