Therm image proof of Ground loop performance

Here is the proof in field testing of Ground loop free heat from intake ground loop to HRV

Outside air intake of HRV ground loop -2 degrees Celsius

Inside of House HRV ground loop temperature + 9,5 a difference of 11,5 degrees from out side air temp

Exhaust Air of HRV of stale air from House 9,6 degrees only 0,1 degree difference  from intake air
