Optimmersion is a proportional controller that diverts surplus electricity to heat water in the immersion tank. It only uses surplus electricity - electricity that is not being used in the house, so it is effectively giving you free hot water. Free hot water; Your surplus solar power is used to heat water in your existing immersion tank. Save money; Drastically reduce your hot water bills as excess electricity is diverted to the immersion heater. Total control; Ability to change controller settings and monitor your home's electricity activity to view real results. Automatic solution; The intelligent controller gets to works whether or not you are in the house, meaning you automatically get free hot water. Increase efficiency; The range of Energeno products ensure all of your ‹Å“home-grown electricity is used, minimising what you pay your electricity supplier. Maximise return on investment; The display of information shows users how much of their own generated electricity they are using and by how much they are cutting their energy bills. The Optimmersion system ensuring all of this household's generated electricity is used in the house with the surplus diverted to the immersion tank

It diverts free electricity to the immersion heater when surplus power is available. Simple to install, it supplies variable power depending on the excess electricity being generated. It automatically harvests surplus electricity and all of it is used to heat water and maintain temperature level. It is installed between the immersion tank element and the mains, no modification to the existing immersion element, hot water cylinder or pipework needed. 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.
