Today, we put on the insulation panels around the number 4 Energy Module. We inserted at least 300 mm thick of insulating boards, more like 350mm to 380mm thick!

We did forget to drill down underneath the tank and insert our conduit pipe for the temperature probe so instead, we pushed it (the conduit) directly underneath the insulation layer so it will at least give us some idea of what the temperature is doing in the sandy soil underneath the module. Oh Well!
We then put on 300 mm to 350 mm thick layer on top to form the lid.

Tomorrow, we will put in the two usual conduits for the water “high” and “low” fill points and the two temperature probes for those same points. Then we will push the final sandy soil around and on top of the module.
