  • The Hotspot is retrofitted to your existing geyser.
    It is shaped like the finger of a glove and fits neatly over the element.
  • The accelerated heating result is due to the thermosiphon effect where hot water is channelled to the outlet for the first-heated-first-used principle, allowing for shorter geyser heating times.
  • The product has a one-year warranty, but has an average lifespan of two years.
  • If the element is changed, the Hotspot must be replaced.
