Ann Kay. - Karl just talked me through setting up my Duoheat night storage heaters. I am so grateful to this guy! He is so knowledgeable and helpful and explained everything clearly and simply. Thanks Karl.

people like you are real heroes! I wanted to break this thing and chuck it away, but you saved the night!

Thanks Carl. you are bookmarked in my favourites. Every year I forget how to set them up and every year i check out your video. Thanks.

Just spoken to Karl, can’t thank you enough for all your help, made things clear for me to use my Dimplex duo storage heaters 😬

Thankyou Karl for all of your advice re my dimplex heaters, you are very knowledgeable in your field and your after service is amazing! I don't know what I would have done without your help! Not once but twice! Trust you implicitly! Have a lovely Christmas Susan🙂

Thanks very much Karl, this is just what I was looking for. You simplified the instructions, I’m now able to understand the settings. Thanks again!👍🏻

Carl your video has help us so so much thank you ... ours was set on the front panel for 3 weeks & pushed our bill up over £300 , your amazing & we thank you for re setting Our heater & our bills 🤩

Hello, just phoned Karl regarding this video...i now know i have been using my heater wrong and using a lot of electricity...thanku for helping me understand how to operate it correctly..and most of all being so patient and kind to this old age pensioner, keep safe many tks..isobel

Thanks Karl your a star, I now know how the storage heaters work!

Thanks so much Karl... I could just do with you taking a holiday in Dorset and coming to sort out the one that doesn't work at all and you'd make my year!

Cheers Karl, just bought one cheaply because not lot20 and only using in the middle of my house to take off the morning chill with the cheap tariff. I was concerned about the front GLP heat which I don't want, but you cleared that up more easier than the instructions, so leaving with blue LED on brilliant!

Karl you are amazing. Thanks for all the help. Karl, you are a superhero. Thank you !

I'm so grateful to Karl Brooks of Tack Electrical for his wonderful video explaining the set up procedure for the Dimplex DuoHeat storage heaters, in which he clearly explains how to do this. I subsequently spoke to him raising a few queries I had, and he was extremely pleasant and helpful. Thank you again Karl - you're a star!!

Very good video and the best thing is about you can call to the number to ask if need help to use dimplex heater. Thank you sir for your help. 👍👍👍

I just want too say a big thanks too Kyle! What a top guy he is. It turned out it was a faulty radio teleswitch and my energy company repaired it yesterday and ny storage/background heating is booming out lovely. Thank you again Kyle!!!!! Gary.

Thank you for this video it's almost making me understand their systems at my mum's. I am confused by the sockets next to each radiator. It has two switches, 1st is labelled 'On Peak Heater' and the 2nd is labelled 'Controller'. I never see any lights on the night storage unless I have the 1st switch on. With the 1st switch on I can do all the actions you explain in the video. However I don't want the radiator to use on peak power, I only want night storage. Will it only use on peak power if I change the bars to more than 1 when it's not flashing?

Hi, thank you so much for this video! You are great! My problem is when i set it up it was no blue light, any way i manage to set it up but from then i cant reset it, not to get off the key, not to regulate up and down, also after 12 it starts clicking until i push + and - and after few mins it starts again clicking i dont know what to do

brilliant thanks Karl

Great video thanks alot

Thanks Kyle, yes I will ring my energy supplier and see what they can do for me! Although I only lived in this flat 1 week before I had my meter changed.

Cheers Karl!

thankyou so so much ...now know what the problem is at least and can look into fixing it .....thanks again your a star :-)

Hi Karl, Thanks for the video. Quick question; any thoughts on how to mend our DuoHeat that had a towel left on it for 20mins to dry and now shows all the lights flashing. We can't alter the temperature at all (appears stuck on full). I suspect it has over heated but we aren't sure how to mend it! Many thanks in advance for your help.

Hi thanks for the video. Could you please tell me how to boost this heater in case if the stored heat completely finish by evening and still need warmth?

many thanks Karl, I thought it worked similar to how econ7 boiler systems worked and I only needed to have one switch on and the second switch was just a boster.

this video was a God send : ) ! just a question ..do you have a video on how to operate the wall timer ?

Hi Karl great video. My problem is that all lights are flashing when I power it on. I followed your other video on this issue however and get LED No.8 flashing on the self diagnostic. However when I push any button at this point it goes back to all LEDs flashing. Any seem to get into the heat setting stage for either comfort or off peak. Any help appreciated. Thanks.

Hi Karl. Is the background setting the amount of heat stored up over night for the next day when the front panel is on low? Cheers

Hi Karl I have two different models one model does exactly what you showed on the video but the other radiator doesn't seem to be able to turn the front convector off...i tap the button down to the lowest setting after setting the night storage level but it just stays at one bar in red instead of turning off Is this right? I'm not sure which rad is the 400i and which one is the 400n... Thanks

Hi Karl, I have a question, I'm not sure if I have the 400 or 500 model, and have 3 heaters in my flat. All three have power to the storage and front panels, and they work overnight and when switched on, but none of the controls work, all I get when pressing either + or - buttons is a clicking noise, and no movement up or down. Have you come across this problem before? Many thanks.

Wow I just moved into a flat that has these with no manual, I have a dimplex wall controller too, do I just leave that on and then follow your guide here? I was really scratching my head trying to figure out how to set the night time mode, thank you 😁

I have four of these (independent) 400n heaters in a house and have a number of questions/issues... i) the background setting controls the level/amount of heat that is generated (and stored in the bricks) overnight but not the rate at which it is released during the day, correct? I think it is a simple case that if the bricks have greater heat stored in them overnight, they will remain warm longer into the day. ii) I've read that these heaters might have a thermostat in them than means the storage heating may not come on in 'milder weather'. If so, this could in theory mean some heaters come on while others don't (if there is a temperature difference between rooms). Is that correct and can this be controlled/overridden (i.e. to come on even when the weather is mild)? iii) one of the heaters (storage part) seems to be running very hot and stays very hot well into the day. Is it possible for the storage heating elements to become 'stuck' on? If so, is this likely to be an element, controller, thermostat or other issue? iv) two of the heaters are generating storage heat but the other two appear to have stopped working (although all panel heaters work). The two that aren't working also make a clicking noise for a few seconds after being switched-on at the wall, although it stops after a while. Could this be related and what could be the cause of the clicking noise (I think coming from the controller area)? Thanks.

Hi,the PCB Board-exactly the capacitor on the board looks to be faulty cause it makes noise after we turn on the storage heater.I do not really want to pay 80 euros for the whole PCB Board I am trying to buy the capacitor separately,but I cant find it anywhere.It is an VISHAY Capacitor 275V MKP 338 2 Series.Any advice where I can get one ?

Moved into a flat with two of these. When I hold down the button nothing flashes and there’s also no blue light. It also doesn’t do any sort of instant heat when I press the plus button. There’s a thermostat on the wall which I think is broken as nothing comes on the screen. I left it on overnight to see if it charges but it didn’t work at all

Hello we've moved into an old property with what must be the earliest release of DuoHeat as there is no frost symbol on the membrane. After much searching I believe this is the 'I' model which has a key symbol not a padlock symbol ('N' model). Have you ever come across these, and do they have a reset button? Thank you.

Thanks for the video, do I need to set the background heat every single night?

Also how do I set up the wall timer

Thanks to Karl for calling me back with some excellent information about these heaters.

Hi Karl, we have a cheap rate Ev tariff and would like a small less than 2ke ie duo 400 n and just turn the storage part on at night can it do that not through an economy 7 tariff juat hard wired into normal circuit or would the fan heater keep coming on instead or as well as? Thanks

Hi Karl, thanks for the video upload mate! I have just moved into a flat with with of these heaters and I set the background setting too 6 bars yesterday afternoon and woke up the next morning and no heat as been admitted from the heater... Both switchs was turned on and the comfort setting was set too the 1st blue bar after I set the background? Can you help please. Thank you Gary

Hi Karl, I am new to this heating system. I can really do all what you explained the only problem is I don't know which switch to turn on, I have three switches, one with a light on which is the main power and then two other switches with no lights on. Don't know which to leave on for the storage heater. I tried last night with all on but no heat in the morning, do I need to do anything in the morning to get the heat from the storage heater or will the heat come out automatically?

Hi thanks for your podt do you have any idea about dimplex XL125 its digital control, no lights come on no boost no heat at all..Thankyou

Hello Karl thanks for this video but after setting it all up do I turn it off from the wall at any point or does it just stay on? And how do I know if heat is stored at nyte and released during the day and not just reheating

I have another question about the controller. The instructions that I have say that the heating comes 'on' between 7 and 9 in the morning and 8 to 10 at night. But this is not the night storage hours. What does it mean by 'on'? Does it mean that during these hours the front element will be heated by the heat in the back storage blocks?

How does it just come on? Iv set the background for about three bars..Then at night when it's warm from the main heat bars set mid way, i turn it off to the blue light...Do you ever turn them off at the wall? I'm finding these hard to understand and i don't want a massive bill hahaha

Hi, my child lock stay ON on my Duo 500i... even if I press it for the 3 second. Can you help?

Hello karl,do these heaters automatically cut of when fully charged at off peak?,also once fully charged (10 red lines)cam you control the amount of heat let out of heater?heater seems to let out constant heat throughout the day,when really I want to keep the hear fir the nightie, thanks mitch

Me and my housemate have this heating system and we are so confused with it! We ended up racking up a huge bill last winter so want to get it right this year! Would you be able to explain it a little more to us?

Hi! The flat I am living now has 3 of these. I have been able to set one but the other two stays at max power and produce a clicking noise when pressing the plus or minus button. The slider doesn't move when I click. Is there anything that I can do from my end or I need the landlord to fix them ? Thanks!

Karl when I leave the blue light on before bed, when blocks are heated in morning, blue light is still on, guy housing say each day I has to press to highest heat, hold switch until one light flashing, then it automatically lights up all along, then fades, then he say set temperature, one to bars light and so on, I'm confused, I have to do this every day all winter, and at nearly 70 gets bit much!

Hi Karl, I have a dimplex duoheat 500i which went through a phase of the red lights ticking when changing over to the off peak period. This has stopped but the led heat level controls are stuck on 5. The child lock isn't engaged. From looking online it looks like I'll need a new circuit board but there are three different ones. 2 for the power supply and one for the heat level controller. Assuming it's the heat level controller one I need. Any advice?

hi so so helpful ......but now it won't stop clicking and the red panel lights won't turn off they're just flashing .. .any advice would be greatly appreciated . thanks :-/

My heater is not going past the min it won't go up what do I do

Hi Karl, when i turn mine all the way down I don't have a blue light. Mines still red. If its red and all the way down does that mean its turned off or is it still using electricity still? (there's no heat but still got the red light) I'm confused 😕

Hi Karl, Loads problems heater, electrician very patronising! He say it's not working cos it's set on 1, I had not touched it since last electrician took panel off 10 days ago and reset it! So how did it go from working okay, then stopped and ended up on setting of 1? Then he set it on front panel I wanted it on back panel, he say its on back panel now, but I will order you a new one, take 2 months can't get them, or parts! As when he orders it, they make me 1 heater at factory build it?? I'm sure they must have a newer model that updates the douheat 500n! Rang dimplex they say stockists all over UK, some have 50 to a 100, some less! What new one will replace this one? Is it Quantum. Thanks Su

Hi Karl, my heater was working okay! It stopped working nightie! It's set at 5 blue light I leave on! Since it stopped coming on at night, if I switch the switches on the wall, it comes on daytime? I was thinking it overheated and that's why it did not come on through the night as normal!

I don’t get it I have set it up, but when i put it on number one the blue one, it’s goes cold and iv got no heat and no stored heat but when I put it on number 5 it gets warm but still no stored heat, does the the first heater come on by its self or do I adjust that as and when needed and does the storage side come on by it’s self because so far I feel like I’m just wasting electricity and money

Hello if the front panel is on blue as if off but the panel is hot what is the fault? Thanks

Hello . Now april has hit us with the increase of prices . With theses heaters can we turn both the plug off at the walls without causing any damage until this winter ?

Hi I am having a few problems. All set up as explained but all my 4 radiators are cold unless I increase comfort mode.

Hi, does anyone know what time the heat comes on once the storage heater has been set up?

I have 2 switches on the wall, one brings the lights on the other doesn’t. What’s the difference?

Hi there I have this system at home one of my radiators is nit getting hot atall I have turned it right up still nothing any ideas I can look at would help cheers

No blue light comes on mine. I just keep switching both switches off because I have no idea which switch is which :/

Hi there I have a Duo500i how do I set it up? Thank you Gary

When the it comes 8 am the storage lights all go off and there is no heat from the rad please help

I'm really struggling with mine. Any chance I could give you a call? Thanks Karl!

Is anyone else’s storage heating costing €6/7 a night?? Or am I doing it wrong I only use the storage heat so I don’t understand

If I press my + button for 20 seconds I still don't get this option !!

In this video he shows to leave the blue light at the end. This goes against all the dimplex installation and user manuals and you will have no comfort heat !! Misguiding

No problems Sean Alway on hand to help others how did you get on? All working or did you need a new meter?
