2015 Anthem, Aquahot maintenance, how much boiler fluid to buy when changing?
Good Morning. I'm planning to change out my boiler fluid this winter. I am unable to find a boiler fluid capacity for the 450D system so I know how much to buy. Does anyone know how much boiler fluid a classic Anthem holds? Aquahot 450D. Also the RecPro brand fluid appears to be about half the price of Century. Not sure why. Thanks.

Might be able to do a search on the Entegra site. I did mine back in about 2018 and posted about it. From memory I think I used about 10-12 gallons for both Aquahot loops and the boiler tank.
I changed my 14 Anthem in 2016 due to numerous issues posted. I switched from the Yellow boiler fluid to red Camco boiler fluid. It was about 25% of the cost. I sold that RV in 2021 and the red fluid looked as good as the day I put it in.
The caveat is they yellow and red fluid cannot be mixed. I used 30 gal of distilled water to flush the old out before adding the Camco fluid. (It’s like $.99/gal at supermarket)
