Settings and terminology

Mixergy tanks are designed to work around your needs - be it fuel types, tariffs or schedules. Here you'll find information on some of the key settings and terminology.

How to achieve the most from your cylinder

To get the most out of your Mixergy tank, we recommend download the Mixergy App. This will enable you to take full advantage of the smart features, machine learning and customisable settings. To find out more, see the our guide to the Mixergy App. 

Mixergy terminology key

• Hot water level: the % of usable hot water available, or state of charge.
• Draw event: any amount of hot water discharged from the cylinder.
• Heating event: a scheduled heating instruction set in the Mixergy App (e.g. 
  heat to 50% at 7am on Monday).
• Maintain levels: You can set your cylinder to maintain a state of charge between a minimum and maximum level. If the level of hot water drops below the minimum level, your cylinder will automatically heat until the maximum level is reached. We recommend a level of 15% (min) to 20% (max) (electric/gas) to cover any small draw event (e.g. washing dishes). For heat pump cylinders, it is recommended to set the maximum to 100%

Fuel type

Flexible tariffs with price volatility (e.g. Octopus Agile, Economy 7 or Economy 10)

• Best time to heat: You’ll want all of your heating schedules to run when electricity is cheapest, during the set-off peak hours.
• How much to heat: If possible, you’ll want to heat enough water to cover your expected usage for the entire day in one heating event. 

Flat tariffs with no price variability (e.g. electric flat rate, indirect sources such as gas boiler)

• Best time to heat: The time you heat won’t affect how much you pay for the energy. To minimize heat losses, we suggest setting your cylinder to heat to the required amount just before the first expected draw event.
• How much to heat: Set your cylinder to heat enough water at the times you need it. Be sure to put your cylinder in 'indirect mode' through the App to ensure gas is used if it is cheaper than your electricity tariff.

Automatic schedule control

It can be tricky to know exactly how much hot water you’ll require on a daily basis, and that’s why we’ve produced an intelligent machine-learning algorithm, which will select the best possible heating schedule for you. This algorithm will optimise your energy use, so you’re always saving as much money on hot water bills as you can. 

Before the machine learning kicks in, your actual hot water usage will be monitored over a short period. You should either set a manual schedule yourself to begin with, or your cylinder will run a default schedule – heating to 100% at 3am.
