Filling Alde Water Tank ( after sanitizing/ De- Winterizing Process)

in Heating/Plumbing & Winterizing
I just finished  sanitizing  my fresh Water tank  ( for 2016 MAX S tab) . I winterized it by the Line Blow Out method and so did not have to flush any AF from fresh water tank or pre-tap lines.  It is now in Camping Mode. The instructions I am following advise to fill Alde water tank by opening any hot water tap and let it enter Alde water tank. However I  do NOT  use hot water from the Tab while camping. So can I just skip filling the Alde?  I assume it will still work for heating the cabin using the glycol fluid.  I assume I will have full access to unheated water once I hook it up to water source or use fresh water tank.  If I skip this last step then I don't have to  deal with  emptying the tank in the  late fall when Winterizing.

    If this was my rig . . . would just leave the Water System in Winter Mode . . .
    with Alde Hot Water Tank by-passed.  Adle will still generate 'cabin heat'.

    That said,
    why not fill the tank and have Hot Water when camping . . . is easier than boiling water.
    And since you use the Air-Blow Method to winterize having water in the Adle 'tank' is no big deal.
    Just drain it (yellow over pressure valve) then air-blow out all the hot/cold line water    .

    I'm not sure...but I'm curious as well.  I have always preferred to have water in the system when the Alde is 'on'.  I assume there is some type of thermal switch to prevent the water heating elements from turning on if no water is present...but again....I'm not sure.  

    In any case, I would agree with @MuttonChops.  It's probably not a bad idea to run water through the water heating system once in while to keep it functional and flushed.

    I would fill the Alde tank so you don't have a large air spring in your water system.  Otherwise, when you turn on cold water then shut it off, it will take longer for your water pump to bring the system up to pressure and shutoff.  Same thing you may experience when you're filling the system after winter blow out and there is still air in the lines.  You'll notice the pump taking longer to pressurize the system and shut off.

    Not correct.
    The Alde Heating Elements (electric or gas) only contact the Glycol 'cabin heat' liquid.
    Water, if present, is heated by Heat Transfer from the Glycol.
