There are certainly lots of levels of craftsmanship out there when it comes to mechanical work. We pride ourselves in making sure our mechanical subcontractors do neat and organized work. Having said that I’ve seen so many “ugly” PEX jobs that you are not alone.

Typically glycol is used when a portion of the radiant system is exposed to freezing temperatures. It’s actually quite common especially when basements are heated, garages, walkways, things of that nature. The only thing I don’t like about it is your can’t get as much efficiency out of the boiler.

I recently moved to Central NY and purchased a home that was built in 2003. I have no experience with biolers or radiant heating. This house has radiant heating through out powered by a propane boiler. The “boiler room” looks like a 3 year old threw spaghetti everywhere. Red tubing going this way and that, in no way does it look like your photos. The boiler is filled with Eythlglycol? or a mixture of water and glycol? Is that normal? Especially since my hot water heater is a boiler transfer style.(Big blue cylinder, hot liquid heats water from the well)
