      What about hard water areas - Does limescale affect Recoup's WWHRS?

      WWHRS and hard water compatibility

      No. WWHRS does not get into the limescale depositing temperature range, as the incoming Cold Water Main is only preheated up to around 25-28 °C.

      The WWHRS exchanger is made from a smooth 50mm internal diameter copper pipe on the waste side, so is essentially like any other piece of copper plumbing pipework, and should be expected to last 40-60 years.
