4-ton GSHP - Hydronic conversion - Page 2

You must have fairly mild winters there if you can still ride... How deep are your loops? My loops are all buried between 8 and 9 feet, our frost line usually gets down about 6 ft.

I can't see any of the photos that you have posted.

I have even gone into the "HTML" code and tried to copy and paste your photobucket image address (AKA: "URL") in my browser, to view the indicated image, and there's nothing there...

What's going on??

You are not alone, man. Something is awry with the internet of late. Post a comment in the thread about posting pictures. A few of my friends/relatives have been having the same issues. Works for me on their WiFi on my phone, not in their equipment. Don't know why.

Humm, I see all the pictures . . . .

Yeah, it's super mild. I'm in Western Washington, we rarely see anything less than 27 or 28 degrees, but that's short lived. I think our annual average temps are in the mid 40's. We get a consistent warm air current from the Pacific Ocean. I went about 6' to 8' on these test loops. We don't get frost below a foot here and actually, even 6" of frost is rare.

Most of my soil is mostly sand with a small bit of clay. It soaks up the rain and drains very well. Great for a winter MX practice track.

That's strange. Perhaps photobucket doesn't support other platforms very well? I'm using Windows 8.1 with the IE browser version 11.

Made a little more progress on the conversion project this week.
I finished up all the brazing and did a pressure test with nitrogen at 300 PSI on the refrigerant circuit. The water side (including the pump) was previously tested with compressed air at 50 PSI.

I also constructed a steel upper frame around the components I've added to the heat pump. The structure allows me to use all of the original sheet metal. I just have to come up with a 12" tall panel for each of the four sides.

I have purged with nitrogen a few times and the system sitting under vacuum, but I need to come up with a micron vacuum gauge before I release the refrigerant into the upper section. In the next few weeks I will be making all of the liquid and electrical connections. Hopefully I'll start heating up this concrete slab around the end of the month.

Yeah, I can definitely see every thing there. Everything there is wrapped in a photobuchet URL, so there's a lot of chance that permissions may not be conveyed properly.

I upload my pix to EcoRenovator, so the chain of addresses to the photo is very short.
