There are tall skirting boards within the property how can this obstacle be overcome for the Quantum heater?

Last updated on 21/09/2017

There are three ways, all of which we recommend.

1) Fit our "Quantum Tall Feet" accessory. These feet should be ordered prior to the installation being carried out. They would be fitted instead of the feet supplied with the Quantum Heater. The overall height of the tall foot is 140mm and can be ordered through your wholesalers, the part number is 080479. These come as a pair, but without fixing screws. The fixing screws that come with the product for the original feet should be used.

2) Cut away the skirting board utilising a "multi saw".

3) Batten the Quantum heater away from the wall, the same distance as the thickness of the skirting board. Dimplex will be releasing a video in the near future on how to do this.

Can the Quantum be installed within a cabinet?

Last updated on 21/09/2017

No, this would not meet the clearence allowance and would create a "micro-climate" around the heater and affect its operation and ability to sense room temperatures.

How does 'boost' work on my Quantum heater?

Last updated on 21/09/2017

The boost element will only operate if the level of stored energy taken for that day is below 50%.

Use this function ONLY if you require a room teperature that cannot be achieved from the Off-peak stored energy, and because you are cold.


If the Off-peak supply is faulty, cannot be used, or you have been advised to switch off the Off-peak so that the storage heaters core can cool down for a service engineers visit, use the boost facility to provide you with heat.

Use the boost with care, as this utilises Peak Electricity (taking the energy at day time at a higher rate).

Please note: For a service visit, which may involve accessing the core of the heater. The Off-peak must be switched off for at least 72 hours, this is due to the high temperatures that are inside the core of the heater. Switch the boost off, set the temperature to max and set the program to HAD.

What do the display messages mean on my Quantum Heater?

Last updated on 21/09/2017

Child Lock Displayed - This has locked the controls. How to unlock this is in the instructions.

Heater Disabled - This may occur if the heater has been switched off for a long period of time, (the battery in the UI has discharged). Ensure both supplies are switched on, set the time and date (this will remove the message). Set up the heater suitably for your needs, program and temperature. The product will require a new battery within the UI. Please contact Glen Dimplex Heating and Ventilation After Sales for a replacement.

School Lock Displayed - There are two situations in which this can occur. 1) Straight after installation, switch off both supplies to the heater, wait a few seconds and switch back on, If the fault has cleared, set up of the heater. If the fault has not cleared then ask the installer to reattend. 2) After one of our service agents or regional engineers has attended the customers property and reprogrammed the heaters, they will need to go back. Contact Glen Dimplex Heating and Ventilation After Sales to discuss.

Boost Displayed - This shows when Boost is in use.

How does 'extra charge' work on my Quantum?

Last updated on 21/09/2017

Firstly, what does extra charge do?

The extra charge function adds incremental minutes to the final calculation of charge required to what will be taken into the core that night. So at midnight the heater will look at historic usage, future requirements, weather adjustments and some other pieces of information and calculate a number of minutes for which charge will be taken. On a typical E7 tariff there are 420 minutes available. Say the unit calculates 300 minutes are required, but an extra charge of 1hr is in place. The unit will now charge for 360 minutes.

Using this function will always add the extra minutes. So should a minimal charge of 80 minutes be calculated in the late spring/early autumn months, the addition of the 60 minutes extra charge will produce a total of 140 minutes, having a greater proportional impact. The extra heat may be more noticeable to the user here than during heavier heating periods.  

Secondly, when should it be used?

If the heater is not calculating a sufficient charge by itself an additional charge can be ‘forced’ from the unit by selecting the extra charge function. For example:

• If you require an unusually high temperature and are experiencing a loss of heat at the end of the day.

• If you require to have a low temperature early in the day then a higher temperature through the evening, but cannot leave the temperature high overnight during the charge period.

• In a situation where under-heating would be potentially hazardous, for example due to user health requirements, and it is preferable to maintain a larger ‘reserve’ in the core. It is rare that this function be required, as in the vast majority of cases the product correctly interprets the requirements and charges sufficiently. This function simply offers a simple override function in situations where the calculated charge, for whatever reason, is insufficient.

The Selector Dial can be turned clockwise and anti-clockwise and enables the required room temperature to be adjusted. The screen colour changes for warmer and cooler settings, showing deep blue through to bright red. The Selector Dial is also used within the menu options to select and confirm your settings. Pressing the Selector Dial once will reveal the current timer mode, the software version and confirm the off-peak operation.

Can my Quantum be installed within a guard/cage?

Last updated on 01/11/2017

Yes. These can be bought from AIANO Ltd. Their contact telephone number is 0207 987 1185.

The property has conventional storage heaters with just an Off-peak Supply, are Quantum heaters suitable for this?

Last updated on 21/09/2017

Quantum heaters and their use with a single supply is still under development, at this moment in time two supplies will still be required for the Quantum. These are: Peak Supply to control the electronics, fan and boost and an Off-peak Supply for the storage core.

Please note: Our Technical Team will not and cannot comment on single supply installations for at the time of writing the company does not condone this, to reiterate both a Peak and Off-peak supply are required.
