What is HephaHeat Low Frequency Induction Heating?

HephaHeat low frequency induction heating is a patent pending method of using induction systems without the need for additional expensive power supplies.

Our systems are uniquely designed to plug directly into mains supplied AC and by utilising the 50 / 60Hz line frequency we replace the large and expensive power supplies normally required for induction heaters.

This provides simplicity, reliability and low cost with our systems - yet brings the same advantages of existing induction heating technology principles.

Principle of operation

The system works by charging a metallic thermal store to a high temperature (500 to 900°C). By using a material such as steel, which has approximately the same volumetric heat capacity as water, substantially more thermal energy may be retained than in a similar tanked volume of water.

When hot water is required, the cold water input is split into two separate branches. One is allowed to flow into the thermal store with the flow rate controlled by a standard valve. When this branch flows through the thermal store it is instantaneously converted to steam which is then mixed (via a steam injector) into the second branch of cold water.

This mix of steam to cold water allows the output water temperature to be controlled.
