I am going to be starting work on my ground loops this weekend and was wondering if anyone had any thoughts on the ground loops that I come up with. I am located in Maine, my trenches will be 2 feet wide 6-7 feet deep. I will be putting a 5 ton units in my house. I was going to just put in 5 loops as we did for my brothers a couple of years ago, but after talking with some folks on here it was suggested that maybe 1-2 more loops would be better. I have attached a sketch of what and where my trenches will be in relationship to my house along with a sketch of the manifold. Any thoughts or suggestions would be greatly appreciated. Thanks. |

I see the diameter of the manifold increases as the volume of fluid increases. How did you determine the 1.25" diameter and 6" spacing between loop connections? Dave |

I don't want to hijack your thread, but I am curious about general loop design practice.
Should the lengths of the loops be equal? If not, are balancing valves needed?
Are isolation valves typically installed on each loop? Is there a recommended isolation strategy?
Do you flush and purge loop by loop or on the entire system at one time?

Thanks geodean. Farmboy, I don't really have any magical formula's to share. I'm not really very experienced in this, but did install one unit with my brother a couple of years ago and I have a manual to the flow controller that we used and it has some examples in it. I don't know if it is correct or not, but it recommends loops 1-3 = 3/4", 4-8 = 1 1/4", 9-15 = 2". I just thought that it would be important to keep the spacing equal between fittings to balance things out (don't know this for sure either) and alternated the order of the loops in and out, first in last out and so on.. I actaully have one trench that will be limited to about 200 feet in length rather than 250, but figured I would just keep the same amout of tubing in that trench as the others and double it up at the end until it made up the difference.
If anyone else has input on this I am very open to suggestions. Thanks again. |
