      NickHydro. We recently had a Solar HWS that was calcified up to the extent it would not heat, we approached Rheem with the question of circulating vinegar through the HWS to clear the calsium, they agrred & said that the Kiwis had much joy using this method. Worth a try?
      Regards Bob

      NickHydro. Further to my earlier post, when we recirculated vinegar through the solar panels the vinegar changed colour to a aqua blue with large consentrations of salt, took about 3 hrs but solar panels now work. It seems to me that the change in colour must be from the slight removal of copper fron inside the panels so this could be a consideration to get a owner to indemnify against early failure?

      I agree that you dont want to work on this yourself!
      But an (honest) plumber will use a multimeter (with the power off orf course) and check for continuity by touching the leads to both posts of the element(s) to see if the element has burst, and also he can touch the metal tank and one of the posts to see if it has grounded out to the tank.
      if both elements are good, the high limit of one of the thermostats could have “thrown”..wich usually meens a bad thermostat.
      all in all, if this thing is over 9 years…It may be cheaper to get a new one and have it serviced regularly! (flushed and anode rod inspected) especially in hard water inviroments.
