Geothermal Part 2

The geothermal installation is almost complete. As usual with these things, it went over schedule a little, so the system won't be turned on until tomorrow. But the trenches have been filled back in, and it's mostly a matter of making the final connections and setting up the zoning system.

Here are some more pictures.

Taken from the roof, this shows 4 of the 5 trenches with the loops in them. Each trench is 150 feet long, 3 feet wide, and 6 feet deep.


Here I am standing in a trench.

Artistic. Taken from the back of one of the trenches facing towards the house.


Here is the yard after the trenches have been filled back in. It will take 6 months for the ground to fully settle, after which it will have to be regraded and then we can plant grass in the spring.


DTE gives a reduced electrical rate for geothermal systems, so we'll be getting a separate meter just for that.


Here's the tubes from the loop field coming into the basement (the entry into the house is shallower than the actual field, presumably to make it easier to work with). Also visible is the second electrical panel for the geo equipment.

The geothermal furnace is on the left, and the water heaters are on the right (there's one behind the visible one there). Also installed but not visible here are the humidification system and the electronic air filter.
