How often do you drain and flush your system with the glycol to replace the antifreeze? I honestly don’t know what maintenance they do but I’ll update as I ask. Reason why I was asking is what I read in my manual for my furnace. It says that when glycol is used in the system that it must be periodically drained and flushed. It says also the glycol breaks down over time and turns to glycolic acid, and this will damage the unit. I am a believer in draining and flushing other systems, cars trucks etc. anything liquid cooled with glycol in the system. However, my boiler system holds 250 gallons.... Not 6 gallons like my pickup, or 2 gallons like my Kubota diesel mower. I am not interested in draining and flushing a 250 gallon system, that is a huge amount of time and hazardous waste.

I have talked with 2 of the users. One has not flushed in 10 years and they had 2 loops freeze. The other flushes his every 3 years and uses an antifreeze similar to RV antifreeze and let’s it run out on ground.
