Product Description


Optimmersion is a proportional controller to add to a Solar Power installation. It diverts free electricity to the immersion heater when surplus power is available.

Optimmersion uses both current transformer and voltage sensors to constantly measure the power being generated by Solar PV and also power in use in the home. The clever Optimmersion system regularly calculates the excess electricity which varies the power to the heating element. The advanced electronics provides a true variable output.

Save money on bills and reduce payback time on your Solar PV system as your hot water is essentially free. Works alongside existing Wattson Solar Plus, Wattson Professional and original Wattson systems.
