Question

Geothermal Heat pump installation


I have read a lot about Geothermal heat pumps and one thing I haven't had explained is the term "header". I was going to put a closed loop system in for my house and it doesn't say anything about a header in the installaton instructions. Tell me if I am missing something. I haven't started anything yet. Thanks for any information you can provide. Brian

I have not installed a system yet and not an expert but I suspect it will look something like this but on a smaller scale for residental installs.

My understanding is the ground loops will tie into the headers, you would have 2 headers one for water in from the loop and one going out to the loop.

a header is what distributes an single closes loop to multiple shorter loops this is recomended especialy in a verticle or angled system you wont have to drill as deep and this allows more constant temps and drecreases the posobility you will hit bedrock remember to space the loops at least 2 feet apart so the heat emitted or obsorded by one line dosnt effect the other

I found a better picture of what they look like. Mine came in and looks similar to these. Mine has a 1.25" inlet and goes to three 1" outlets for the field lines.
