Water to air exchanger pictures....

Postby royerm » February 18th, 2015, 10:55 am

Hello everyone..

I'm in the process of getting/planning for a kit with Tommy and as we see a lot
of documentation/pictures of the Kit and pellet stove itself

I'm wondering if anyone has pictures of the plenum heat exchanger :roll:
and the sizing...
My Plenum is 20x20 inch.

Regards

These are pics of the 18 x 18 coil installed into the plenum of my GeoComfort forced air geo-thermal furnace. The coil fit snugly in the plenum. The 18 x18 is the size of the coil itself. The ends stick out further.

I have more pics in my other computer. I had a computer crash :oops: in the middle of the crosslink kit install. Here is where the coil came from: http://www.freeheat4u.com/Water-to-Air- ... _c_13.html Appeared to be good quality and shipped fast, My sidearm heat exchanger[domestic hot water] also came from them.

Something I am going to re-do is to add shut off valves so that the coil can be removed without loosing large amounts of the Glycol mix. I did use unions at the coil so it could be removed for cleaning or replacement if needed.

Barry....
Good idea about the shut-off valves...will include on my to do list :idea:

Are you reducing from 1" to 3/4" at the plenum ???
Do you plan to remove the air exchanger in your HVAC for the summer???
Any special reason for using Glycol????
Is your Geo-thermal coil above the coil for the CrossLink????

All my lines for the crosslink kit are 3/4. The coil for the crosslink kit is above the geo coils. It is a forced air GoeComfort furnace. The coil for the crosslink kit does not need to be removed in the summer. The reason for glycol in the system is for freeze protection should things go terribly wrong and temps in the house drop below freezing. The glycol also greatly reduces the calcification and mineral deposits in the system. The ph of the system should be checked on a regular basis just as in any boiler system.
I put lots of full flow ball valves in all the plumbing I have done in my house. Lots of unions also to allow dis-assembly and replacement of components. I also added extra temp/pressure gauges to the system to be able to monitor what is happening. The kit comes with temp/pressure gauges for input and output of the coil in the stove. I added temp and pressure gauges to after the sidearm heat exchanger and coming out of the coil in the plenum. I should add one more to monitor the water temp of my domestic hot water. I like lots of info. My Geo system came with none. I can only guess what is happening with that.

I just re-thought your question about the 1" line. The lines going in and out of the plenum coil are 1" and I reduced to 3/4" on both. I also have a screen/filter in-line before the plenum coil to prevent anything from getting into the coil.
