Recent installation

Here are photos of an installation at my own home. I am testing a small heat exchange matt of my own design to attempt to reduce the overall ground needed for a loop installation. Other research and geothermal air conditioning companies have already shown that a small compact design heat exchanger will work. My plan is to reduce the ground needed by 1/2 to 2/3 what would be currently needed. I will be testing it for a full year over summer and winter. Already it has shown to be effective beyond original calculated expectations. Now after nearly 3 years it has given me sufficient results to design a smaller loop area if needed.

 

This is the ground loop of a future 9kw unit to go into an extension of an existing home. Here we bury 1200m of 25mm pipe in a slinky fashion in trenches 2m deep. Each trench was dug one at a time, pipe laid and backfilled before the next one was done. A drip irrigation line is laid with the pipe and will be connected to a rain water tank to help maintain moisture on the loop for better heat transfer, mostly for summer. Three trenches were dug with a total area of 54m2.
