I worked on a geothermal well or two.

Bump a hole a mile deep and get water @55F.

Geothermal does not heat the building, it offers a buffer.

I do not see their temperature expectations manifesting without a nearby caldera.

They're talking about 176F. Superheated.

Not true.

You can use a heat pump to boost the heat out put of geothermal systems and for the most part this is how most of the systems in the north are set up.

But a 176 degrees F you wouldn’t need the heat pump. That is more than sufficient to heat a building if there is enough water to circulate.

What I do notice in the article there was no mention of the pay back period for this system.

With that kind of money just for drilling the hole I would imagine it will be in the range of 15 years or more depending on the size of the building and future energy cost.

This is more or less a demonstration project and a political stunt aimed at the Green Party.

Geothermal energy available is not consistent across different areas.

At 5300 feet deep (Vertical Hole) the temperatures average about 175 degrees F.. At 11,000 feet they average around 300 deg. F.
