Optismart® Hot Water
The all-in-one smart solution to maximise auto-consumption

Why choose Optismart® Hot Water?

It provides automatic hot water by proportionally diverting surplus renewable electricity to the immersion heater. It starts heating water from 50W, and it gets its data using current transformers. The solution is fully automatic and can be added to any solar power installation and immersion heating system.

Optismart® Hot Water allows for standard, predictable and repeatable installation thanks to the wireless connectivity between the controller unit and the power throttle.

It has multiple timers allowing for use of off-peak tariffs to ensure the homeowner is getting the best possible rate for heating water.

The colour display shows how much electricity is being generated, used and how much surplus is being diverted to the tank.

Optismart® Hot Water can cater for multiple tanks in either a shared or cascaded formats. The incorporated Wattson technology means that homeowners can add an Optiplug to continue to make the most of their generated electricity once the tank is full.

Optismart® Hot Water has a Wattson transmitter integrated so the Wattson display will show you the amount of energy being diverted to the tank in realtime. Adding an additional Optiplug will alsogive your property a complete solution to make the best use of your spare generated electricity.
