Ancient Electric Water Heating.

I agree with your answers elsewhere.


The book assumes an efficiency of 88 per cent in its text on the subject  (not mentioned in the question) . It uses the formula:


Gallons = kW X time in hours X 300/ Temp. rise in degrees F.


Not too difficult, even in non metric units.

  • How is the Heat Wayv different to a resistive/immersion coil?



    An immersion coil is an electrical resistance element that simply transfers direct heat into a volume of liquid. The rate of electrical current transfer in the element has some corresponding loss in the transmission, delivering approx. 99.5% of its energy into the liquid.



    However, there is dissipated volumetric loss that directly affects thermal efficiency which has to be taken into consideration when evaluating overall performance. This thermal loss equates to 1% per radial centimetre from the element during its heating phase and once temperature is attained 03% loss per radial centimetre during its stand-by reheating phase. Accordingly, an immersion coil situated in a tank with a diameter of 450mm (R225mm) would be just over 75% efficient during the high-energy consuming heating phase.



    This type of unit is ordinarily used to heat hot water only.



    By contrast, a Heat Wayv consistently maintains efficiency without operational loss and achieves the required space and hot water temperatures on-demand by using an innovative optimised three-phase heating cycle. Firstly, it fully maximises current resistance in signal generation and amplification by utilising convected waste heat to elevate the initial water temperature. Secondly, 100% of the generated microwave signal is transferred into the liquid via confined cavities and highly dielectric materials to reach nominal thermal temperature. Finally, optimal usage temperature is attained and maintained by latent heat transfer into the liquid through the use of proprietary exothermic diffusing insulation.
