Can I set demand heat / extra charge at night on my Quantum heater?

Modified on Tue, 27 Jun 2023 at 12:28 PM

Yes. If you select the extra charge function it will force the heater to take some charge overnight regardless of the temperature.



Series G5 G6 G7 G8 G9 Z & Y

To set see steps below-

hold menu and advance down together

highlight charging and enter 

highlight additional charge and enter

turn round dial clockwise and select hours up to 7 hours extra charge.


We advise to set the % offset rather than the extra charge. Search article: What is the "Heat Demand Offset" setting on my Quantum & how do I set it? 


Series B C D E F G

Hold round dial and extra charge function is located in that menu.

Scroll down extra charge

Select extra charge hours required and enter.


It will add that number of hours on top of the calculated charge. i.e if the heater calculated the heater wanted to charge for 90mins and you selected 1 hour extra charge it will charge for 2.5 hours.


Please note: By setting an extra charge, the heater will be using more off-peak electricity and running costs will increase, but in return for greater warmth.
