Get the model number and serial number off your Aqua Hot and then call the folks at Aqua Hot, They will be able to tell you exactly what your specific unit uses... Also take note as to what your filler cap looks like... The type cap is another tell tell. The older units used regular antifreeze the newer units use boiler antifreeze... Which ever your unit uses you can add a 50-50 mixture to top it off...
My unit was built in 2003 and uses regular antifreeze, my coach is a 2004 model..Not sure when the cut over was...

The OP has a 2008 model. Propylene Glycol is what is used. Doug
