I got a $58k bid to do geothermal at my farmhouse in the Driftless. I think $30k was drilling. Can't get an itemized bid to save my life, but it hardly matters when the geothermal bid comes in at my whole budget for HVAC and solar. That bid is rich people shit, or at least young people shit. In the grand scheme of things, a minor heartbreak, but a heartbreak nonetheless. Rooting for Dandelion so hard.
I loved this episode! I am so heartened to see brilliant, motivated, future thinking, right minded people working to save this planet in spite of all the work the current administration is doing to negate as much progress as they possible can. I wish them every success.
Kathy sort of avoided the questions about whether their, or any, GSHP would get better treatment from a utility other than various stacked incentives.
However, for the developer of those subdivisions, in CO, where the extreme winter air temps are regularly -10F, I'm sure Lennar with GSHPs is being charged less for the entirety of electrical service from Xcel than if it built all these homes with ASHPs, which might have twice or more the anticipated electrical draw at that extreme morning peak.
Sounds like Dandelion has been making some sound decisions about markets and design. I'm having fun imagining Sven and the crew in Sweden "taking them under their wing." Oh the poor Americans, they really have not been making much progress in 20 years.
Also, regarding other antifreeze than propylene glycol. The Euros have been using "brine" solutions for a long time. More corrosive but I think almost no viscosity penalty at low temps.
Another "we can't have nice things;" one of many "non-tariff barriers" protecting the US/Canadian HVAC & plumbing industries.
Hi David, liking your work. Listened to you ground source heat pump episode. You may not be away if this UK company and product which is perfect for retrofitting difficult to address urban areas where installing ground loops is not very feasible/ super expensive. Take a look. ( I have no interests in this company) I just like tech that works. https://kensa.co.uk/networked-heat-pumps. I think it’s potentially a much cheaper solution for multiple homes too.

Go Dandelion! a big breakout is what we need and hopefully the Lennar win gets it started.
A single bore hole and a trench to the house is way less invasive than the massive field it took when geothermal was installed at my place. Nice job.

Great episode! I had a few questions… and I think chatgpt had pretty good answers. In case anyone is interested ….https://chatgpt.com/share/682360c1-6da0-8008-b03b-c3b3e4e054d8
