[QUOTE="John Roberts, post: 113406, member: 126"] Re: Incandescent Lightbulb "ban" 2014 I can imagine there being huge variability due to local ground geology. Ground water or soil moisture will affect thermal conductivity. Near the surface the soil is like a RxC so like a low pass filter with lag (sorry I think in terms of electricity).. This time lag is useful to take advantage of the earth's thermal capacitance to use residual winter coolness in the summer and delayed summer heat in the winter. You need to go something like 30' deep to get away from surface weather variation, and when you go deeper you start picking up heat from the core... This temp rise can be as small as 1 degree per 100 feet, so you can warming but not much cooling down thousands of feet. ===== With a new build, I would be very tempted to go overboard on insulation to reduce the amount of heat/cooling you need. A fairly cheap incremental investment at that stage. I doubt I am the only one with energy cost increases so expect it to keep going up. Of course you could get lucky and hit natural gas while drilling a water well. :-) JR PS : I wonder if combining a septic system with heat extraction system has any merit. It might be nice to recapture some heat/cool from waste water. I wouldn't want to deal with service calls. [/QUOTE]
