How does HydroNova save energy relative to immersion heaters?

HydroNova uses a revolutionary new “Phase Change” technology to provide heat. When the element is charged electrically, the materials in it change “phase” from a liquid into a solid.  This “charging” process itself requires very little energy relative to heating an equivalent volume of water in a Immersion Heater.

When cold water is passed through the heat exchanger, the material changes phase back into a liquid. Heat Energy is only released at the is point.  So the element – after charging – can remain in solid form for a very long time, without ever releasing any heat at all. This saves additional energy that immersion heaters consume even when they are not used.
