BEATING THE warm WITH GEOTHERMAL COOLING

A while back, [Erich]’s oil heating system was due for a few repairs. provided the boosting cost of fuel oil, as well as a few incentives from his Swiss government, he made a decision to opt for a a lot more eco-friendly heating option – geothermal heating. The system works well in the winter, however it’s generally useless in the summer. [Erich] made a decision to put his 180 meter investment to work for the summertime heat, as well as made his geothermal heating system into a cooling system with a relatively low investment as well as very little cost.

The stock system works by pumping chilly liquid from [Erich]’s under floor heating into the Earth. In winter, the surface is always chillier than the ground, therefore heating [Erich]’s home. In the summer, the circumstance is reversed, with the awesome earth insulated by the baked surface. All that was needed to reverse the heating system was a few minor adjustments to the heating controller.

Stock, [Erich]’s warm pump controller doesn’t have the ability to run the system in reverse, so he relied on a Freescale board to turn the compressor off as well as the pump on. With the additions, [Erich] is utilizing 50 Watts to pump 1.5 kW of warm directly into the earth below, a relatively effective cooling system that’s generally complimentary if you already have a geothermal setup.
