I read the other Geo articles referanced. Not sure I agreed with all that was stated. I researched it for about 3 years before building a new house 4 years ago. I have 5 acres with a 1 acre pond built for Geothermal heating and cooling. It works very well. We have 6 tons in the house and 10 tons in the shop. there is over 300 feet of 3/4 PE 3408 tubing per ton and is manifold together separately for each system. The home unit we had subcontracted out and I built the shop system. I only use the shop unit for heating because we put in radiant heat in the shop floor when we built it. Our heating bill is about $300 a month in the winter and about $140 total a month for cooling and all the electric we use.
I have an aeration system in the pond with the tubing and never had a problem as stated in the other blogs. If the tubing is anchored properly it will not float. We do have two aeration points in the pond. One in the middle and the other beside the dock in 4 foot of water. In the winter I shut of the one in the middle and let the shallow one run to keep the pond from freezing over. Water temp at the bottom is a good 40 plus degrees.
The tubing is tied into coils where apparently the CC span. If the eggs drop down the larger fish will not be able to get to the eggs. (did not know this when building and installing the tubing.
It sounds like I need to add more LMB and or HSB. I guess I need to buy some large ones. How large do I need to have them to survive and how many would you put in? There is a lot of small RE and HBG in the pond also.
When I get a chance I will post photos of the pond, the coil system and the geo systems in the house and shop. I will be glad to share whatever information I have on the systems. They do work very well, but you need someone experienced to calculate the system and pumping size to have an efficent system.
Share your doubts about where it all started, then again dosen't matter to me.
Unfortenatly there is a big loby (political) arguing against geothermal energi.
It's clearly a environementel friendly (sustaiable) alternativ, wich makes some X? against it.
Here in Norway I see (glimse) a funny or weird aliance, politcans (environemental friendly?) argue against small privat run or operated geothermal projects.
Try to put restricstions, registrations and limit them in the most peculary and odd ways.
How can that be ? Well my conclution (for now) it is wery hard to put tax on a self sustained,comunity/home, wether it comes to energy and or food production.
So in a way the odd aliance right/left wing politcans walk hand in hand with oil/hydro/wind/any... producer including giant food producers/importers/distrbuters.
And some how these aliances manage yo keep us
(the people/voters/consumers) buisie agreeing with one side or another, instead off exploring and utieleasing this and other opertunieties.
Anyhow I'll add another link on the subject even iff it's a bit off the heading off thread, it fits the developement?
http://www.heatspring.com/downloads/intro/GeothermalSurvivalKit.pdfIts a bit more pinpoint towards small housholds and more up to date, still old (2008) in this field, enormues developement here worldwide.
I'll throw upp another link as well, its a spinoff but still related? or opertunety to pond management. Maybe it should have been posted under RAS?
Good reading (basics) and links to get/dig deeper iff interested.
