So a year or two ago I tried something simple to see if it worked, I put a sump pump out in the creek in my back yard. Hooked a water hose to it and ran it through a window in my house that attached to an old car radiator. Then ran the other end of the radiator back out to the creek. With a normal box fan on the radiator it could cool my house down almost as good as the window a/c I have. I used it for a week or two but ran over the hose with a lawnmower and never bothered to fix it.
So I am thinking now that I acquired a new toy
I am wanting to redo this system but make it a bit more permanent and better working. The plan is to dig a really big hole in the yard at least 6ft deep so it is below the water table in my yard and put a large tank of some sort in the ground. I am thinking of a 500 gallon tank. I can fill the tank with water and it will pretty much stay at ground temp of 55 degrees F. From there I can pump the water through a car radiator/fan setup in the house somewhere and cool the house with very little electric required.
a 3/4" pipe should be more than big enough for the amount of flow I figure and a small pump is all that will be needed since there will be no lifting of the water, just pumping it closed loop. All of that is just a wild guess but it seems like it should work. If it does work it would be really cheap to keep the house nice and cool all summer. The house is 25'x40' with 7ft high ceilings and no insulation at all, just some blow in insulation added to the attic. If anyone has any experience with something like this and would know of what size tank and flow I actually need let me know.
I could insulate the house but it costs me like $300 a winter to heat it so it really isn't worth the trouble. If this works I have some strange ideas to try for solar heating
