Harver Africa



Induction heating explained

The Harver geyser relies on a combination of processes to recover heat and produce hot water which are explained below.


It relies on the unique characteristics of radio frequency (RF).

When an (AC) is passed through electromagnetic power generators located on either sides of the geyser eddy currents are produced at frequencies of between 100 to 400 kHz (on average 4000 times higher than the conventional resistive element operating at 50 Hz) and generates precise and localized heat faster and more efficiently than a conventional resistive type geyser.


On top of that, additional heat is produced within magnetic parts of the geyser (heating coil and tank sides) through hysteresis – internal friction that is created when magnetic parts are subjected to an oscillating electromagnetic field.


Because the Harver geyser operates by combining different processes of heat generation we are of the opinion that it cannot be classified solely as a conventional resistive geyser, but rather as a heat recovery geyser/appliance, which is similar in combining a conventional geyser with a solar panel, but in this instance the solar panel being replaced by radio frequency energy as a heat recovery / transfer process.
