When my Alde system turns on for hot water it has a loud hum or droning coming from the unit. I don't remember it being that loud before. Is that normal?

    What year TaB and model?  Is it the Alde 3020?  Have you checked the glycol level?  Have you checked the glycol pump setting?  It should be 2 or less.  Are you using the fresh water tank and water pump or a city water connection?

    2020 Tab 400 Boondock Lite w/3 way fridge. Alde 3020. Glycol level good. Pump on 3. On fresh tank now. Same thing on city water. Turned down to 2. Now it's really quiet! Thank you very much. Very little info from dealer or Nucamp. Closest manual I could get was 2018. Still looking for Air8 literature.  Thanks again.
