well you could always go geothermal if you want to save money on electricity. bury pipes and or containers in the yard. ground is aroun 77 or so 4-5 ft down I think.
This is a serious option that I will look at. I have a pond in the back yard, oh, say 80 feet from the garage. I figure If I get down 8 feet I should hit damp soil, which should be nice and cool. With Geo, i need to have a long trench at the 8ft depth to ward off all that nasty heat. The big question is what kind of piping in the ground to get good heat transfer. I am thinking coper tubing, but I am afraid of how it may corrode over time. I would only pump freshwater through the geotherm system and put a titanium heat exchanger in the tank/tanks.
I have drawn up plans for this in the past, lots of good talk about them, question is can I get a trench deep enough at a reasonable cost?
Now I do plan on having a pool built... HUMMMMMMMMM
Wonder if I could work out a deal with them to dig me a trench... .hummmm....
The more I think, the more I like the idea of the 55 gallon barrels buried in the yard. The barrels are, say 3 fee tall, and I would want the tops, say 4 feet under. That is a 7 foot hole, at at least 2.5 feet across... how hard is it to dig a 7 foot, 2.5 foot deep hole, with a shovel...
Ok, I give, how do you dig such a system without it caving in, etc?
