Induction Geysers: are they a green option if you have no sun?

induction geyserThe Gorgeous Green House outbuildings are in deep shade. Their distance from the main house means that running water from the solar geyser is not viable.  I’ve been looking into an induction geyser as an option just for the outbuilding.

How it Works

Using a magnetic induction process, the water is heated more rapidly than conventional water geysers.  The electrical supply to the generator in the unit is converted into a magnetic field which heats the water.   There is no direct alternating current (AC) in close proximity to the water, which makes the unit safe.  Quality unit includes a high density thermal insulation layer, to sustain the water temperature.  multiple protection measures usually in place: dry burn, overheat, low/high voltage, surge and overheat protection

Electrical Usage

  • To heat a conventional 150L geyser from 20’C to 65’C takes two and a half hours and uses approximately 7.8kw of electricity
  • To heat the same amount of water via an induction heater will take approximately 1 and a half hours and uses approximately 3kw of electricity
  • Operating cost Approximately 1/3 of the cost of a conventional geyser
    Substantial water saving due to location of the unit


  • Easy to install
  • Quick access to hot water
  • Only uses power while heating
  • Saves water
  • Saves electricity
  • Saves space
  • Exceptionally safe
  • Requires a 15 Amp wall plug – just plug in and switch on


  • The unit needs to be placed close to the are of use as heat will be quickly lost through the pipes.
  • If the unit is at a distance, water pressure will also be impacted


I need to purchase a 75L geyser as I will be operating a shower for one person everyday and a second shower for occasional visitors.  The cost is aprox. R6 000.00 ($700.00).  Much the same as a conventional geyser.

Looks like an easy decision to make!
