The GEM-C uses wireless technology and a single power sensor clamp for simple installation in almost any situation.

Clear LED indication shows grid import & export power, heater power and temperature.

A 1 or 2 hour immersion manual boost function is also provided.

The GEM system works by accurately monitoring the power being imported or exported and always diverts sufficient power into the hot water system in order to keep the exported power to as near zero as possible whilst at the same time ensuring that no additional power is ever imported to supply the hot water store.
