What would be considered an acceptable heat gain in your glycol loop. In the glycol reservoir we are at 25-26F. By the time the header reaches the fermenters, the temp is up to 33-34F. Like so others, we cannot crash our fermenters the past few weeks with the heat and humidity so high.

The least amount of heat gain in your lines possible is the most acceptable. Insulate them so they are as nearly air-tight as possible, with at least 1" of closed-cell foam. Use contact cement and insulation tape to seal them. Heat gain from condensation is very significant.Timm Turrentine

Hi,
If you have a well insulated piping system you should not see any heat gain.
With that heat gain you loose a lot of energy and it will cost you a lot of money each month to run your system. That will be less profit on your beers.
For example if we would install 400 ft. of COOL-FIT ABS Plus header piping in 3" diameter and we would pump 119 GPM of 25 F Propylene glycol with a concentration of 35% through this system and our ambient temperature would be 104 F then our media temperature in the end of the 400 ft. would be 25.16 F.
So it is very important to install a well insulated piping system because the cost for that is only once but if you try save so money up front and take some shortcuts you will pay for it every month and it will end up costing you way more money in the end.
Please don't hesitate to contact me if you have any questions
Cheers!

Def check your pipe insulation. The thickness of your pipe insulation depends on material the pipe is made of, the temp of the liquid going thru the pipe, and the extremes of the ambient temp in the surrounding area. I have spent the last two years replacing old moldy half inch insulation from our header. Two problems, the insulation was not thick enough, and was not sealed near well enough for the humidity we have in the Ohio Valley.Joel Halbleib

What is the diameter of your cold glycol header? I've seen headers as small as 3/4" in use, which is another cause of excess heating. The larger the diameter, within reason, the lower the surface area to volume, making it much easier to insulate.Timm Turrentine
