Boiler Antifreeze Gold or Pink?
Auqua Hot hydronic system needs to be topped off. Which antifreeze do I use? Choices are Gold or Pink and do not know which one. HELP.. What is the difference?

The pink is Camco and available most everywhere in concentrate form for about $15 a gallon and makes 2 gallons of fluid.
The "gold" (actually yellow) is Century, hard to find, used as is (not mixed with distilled water) and I've seen it in RV stores for over $50 a gallon.
But, don't mix the two. Luckily my AquaHot came with the Camco.

Thanks for the response guys..... not sure what is in the system right now, so am going to have it serviced by an Auqa Hot Tech on Thursday. At least I will have a base to start from for future ref..... Thanks again for you rapid response.

All - AQ system uses the PINK stuff. The oasis uses the yellow stuff. Don't put in the yellow stuff in an Aquahot. It comes in two flavors, concentrate which is mixed 50/50 with DISTILLED water, or the pre-blended version in gallons. According to AQ you don't need to ever change it but will darken over time, and thicken. So I would change it at the 8-10 year point, you don't need to get all of it out, but let it run into a catch basin until it stops flowing. Close valve and then refill with new cap in place. Use the overflow bottle to get it all the way up to where it quits taking fluid out of the overflow bottle, then top that to between the cold and hot line. Amazon most likely has both kinds and is most likely cheaper than many places

Ok, then they changed what they are using, since mine is 07 unit. I stand corrected. Good thing to know as mine only takes the pink stuff. When went for tour/service school, even the new unit they were talking about, used the pink stuff, it was CSA approved. But have not been back to school since 2010.

My 2013 oasis had the pink stuff. Newmar tends to switch every few years or so, so be sure and check your system.
