As we plug away on this earth battery aka climate battery for the geothermal heating, we laid out the pipes and started the process of putting the dirt back in.
It took 3 days to excavate and 2 days to put 177 tons of dirt back in.
Here you'll find all collections you've created before.
I like your idea of combining the PEX pipe with a solar hot water heater and the climate battery.
I'm currently designing a climate battery and deciding between using culvert pipe or barrels for the manifold. Barrels would be way cheaper!
