MicroHeat Technology uses electrical energy to generate continuous flow hot water. This water heater booster technology exploits the electrically conductive properties of fluids that allow the fluid to be ‘directly energised’. Directly energising a fluid electrically causes the fluid to heat up – this is a process called ‘Direct Energy Transfer’. This process heats the fluid without the use of heat exchange technology (heating elements), rather passing energy directly to the fluid using a set of robust, inert electrodes. Directly energising ‘conductive’ fluids (e.g. water, glycol) in an infinitely controllable manner provides an energy-efficient and highly effective means of producing continuous flow electric hot water.
When applied to water heating, as is incorporated in the Continuous Flow Electric Water Heater (CFEWH), the ‘Direct Energy Transfer’ Technology provides an extremely energy and water efficient hot water booster solution with additional benefits such as accurate and safe temperature control and no scaling.
The continuous flow water heater has demonstrated the effectiveness of the Technology application by delivering market leading stable hot and warm water temperatures safely and continuously. This is achieved via a microprocessor controlled digital system that repeatedly monitors and reacts to changes in the characteristics of the water being heated, 100 times a second.
The CFEWH design and digital control accurately calculates the amount of electrical energy to be supplied to heat the water by emulating the Thermal Heat Equation. The accurate transfer of energy is made possible by the fact that our continuous hot water systems do not use heating elements (heat exchange) and as a result does not experience “Thermal Inertia” .
Using electrodes to transfer the energy into the water stream means that the electrical energy is applied directly, not via heating elements which are significantly hotter than the water. Applying the energy directly results in the electrodes being the same temperature as the water being heated in the continuous flow hot water heater and hence does not suffer from scale and stress corrosion as heat elements (either bare or sheathed) do today.
 Thermal Inertia – The degree of slowness with which the temperature of a body approaches that of its surroundings and which is dependent upon its absorptivity, its specific heat, its thermal conductivity, its dimensions, and other factors.
