GEYSERWISE Dual can be used on a regular electric geyser or with a GEYSERWISE photovoltaic water heating system. Provides full control over your energy consumption.

  • Provides clear readings of water temperature, time, day, heating mode and malfunction conditions
  • Water can be heated automatically or manually
  • Simply set up to 4 different temperature settings between 30°C and 65°C (factory setting of 55°C)
  • Programmable timer with 4 x time setting that can be set daily
  • Equipped with a mechanical thermal cut out at 90°C & notifies you of error conditions

Based in Cape Town & started in 2004 by Meinhard Fourie, Geyserwise found a need in the market for measuring, managing and minimising electrical consumption of the everyday residential electric geyser. An electric geyser represents about 40% of the power consumption of an average South African household: Geyserwise products enable tangible savings of hundreds of rands every month. Geyserwise products can also optimise the operation of solar geysers. All products are designed and manufactured in South Africa using durable materials.
