Back in summer 1988 in Champaign, Illinois, I was a guest in a new house for dinner, and it used geothermal heat capacitance (or some similar term...basically i think water tubes buried a bit lower than the house) to essentially provide access to average year round temperature.
Since the climate there swings between extremes, this significantly lessened their electric/gas bills to the point of being laughably small...essentially a heat pump connected to the water tubes, if I remember.
- lambda 4y agoIt's called a "ground source heat pump". Unfortunately, they require either a very large area to dig very shallow, or they require drilling down very deep, or they require a pond. I got quotes for the drilling once, and it was prohibitively expensive.
- onlyrealcuzzo 4y agoHow long ago? Haven't there been a lot of drilling advances?
- patd 4y agoI’m in Europe. 3 drills of 75m was quoted to us at 16k€, enough for a 10kW heat pump.
