Hello everyone! I've been a long time lurker, and have learned a lot! this is my first question:
I have had a 4 ton geothermal lake loop system installed.
The pipe is standard 1-¼" poly pipe that is laid in a trench for about 80 feet from my home to the lake. At the lake it goes out in the water an additional 1300 or so feet. There is about a 300 foot header, then 2 parallel loops at the end of the header of 1000 feet total
the pipe is anywhere from 12 feet deep to 20 feet deep once its out into the lake.
the other day while swimming i noticed the header pipes were laying right tight against one another on the bottom, so i dove down to separate them thinking this would be better for thermal dissipation but the installer has apparently zip tied them together.
Is there any reason i should go down, clip the zip ties and separate the inbound and outbound header pipes? or does this even matter?
My thinking is that the warmer inbound pipe will be cooled by the colder outbound pipe (in a heating application) and therefor be somewhat less efficient than if the two pipes were separated by some space.
some other information:
the property is in Muskoka Canada where we will only ever use the system for heat, no AC at all.
the lake is large enough to support the system, its probably a 200 acre lake if i had to guess.. maybe more.
I hope this is a clear enough situation to get some answers on this. |
