Thank you so much. Came home today and no heating. Realised boiler pressure had dropped. The user guide was useless. But your video helped sort the problem out. Very much appreciated.
Excellent, clear and very informative. Quite simply a tutorial that doesn’t overwhelm but gives all the necessary information to acquire knowledge along the way - n and solve the problem at hand. Marvellous! You’re a star Mark!
I just moved into a house that has this boiler and the previous owners didn't leave the manual behind, nor was the manual I found online very helpful. This video helped me to get things set up really quickly. Thank you for taking the time out to show people how to use this!
Excellent vid. I am a non DIY man. I know the difference between a hammer and a nail but that's it!!! With your vid, I just sorted out my boiler. Now, thanks to you I know what to do. Thank you. You da man!!!
Thank you for the video, my boiler was using £1 to £1.50 a day on standby, I did not understand why until I found this video. The comfort setting was on .british grass fitted it and did not go over the functions 3 years ago :)
Omg you have helped me so much, my pressure was low & had no clue which button to adjust. Was planning on phoning in sick as I couldn't imagine going to work without bathing. I followed your how to steps & now my water is hot again. Thank you so very much🥰
Scotland, today it's getting cold now, I'm 70 & scared to adjust my boiler settings. Hot water is easy to understand but central htg what is correct temperature. I live in a 2 bedroom bungalow. Also it's summer, htg off, hot taps not running, my boiler fires up for minutes for no reason? Ok, done the tutorial at the boiler & now I know why it fires up as said - COMFORT! its now off. Set hw & will see how that goes & raise or lower. Htg, also now set at 55c & will monitor. Only thing is my rads also have a adjuster for them, not too sure on that, maybe Tango Mark can help there too. I was going to call the council house people but no need now & they wouldn't know as much as Mark. Glad I Googled this, the wonders of the internet. Thanks Mark (can you tidy my house?!).
Thank you Mark for this straightforward and informative tutorial - much better than the DVD that came with my Vaillant Ecotec Pro 28 back in 2013. I knew most of it but you have cleared up a couple of issues. Well done.
Thank you. I was looking to shave diwn the gas bill (aren't we all!) and i found this very helpful. I found the heating set to a whopping 75 and the comfort button on... now set to your recommended levels and i can see how it goes. Thank you!
I read that if the water is not over a certain temperature there is risk of leggionnaires disease ! “Yjd primary method used to control the risk from Legionella is water temperature control. Water services should be operated at temperatures that prevent Legionella growth: Hot water storage cylinders (calorifiers) should store water at 60°C or higher.”
Brilliant video, turns out my Vaillant ecotec pro28 has been in comfort mode since I've been in this house in 2015, and I'd always wondered why it was turning on randomly night and day! Even the plumber didn't know
Thanks this is my exact boiler though I do have the manual 24 hr time clock as well. I found you when I was looking for how to control the preheat function. You explained it very well.
Fantastic tutorial ,clear and concise.Thank you. One question ,what temperature would you set for UFH ,i have ceramic tiles for best heat conduction ,but set at 43 thermostats never seem to get to temperature .is there a band of acceptable temperature range to set boiler to dependant on outside temperature ?
Great video, but I'm missing the installers menu where in my opinion sits the most important setting: d000 - output power. This is the real money saver. It's default set to the maximum power consumption. I've set to 6kw which still keeps my house warm but only cost me 5,7 m3 gas per hour. Also, like others mention, do not set the hot water below 55 c degrees
First at all thanks for this video which I found very informative on how to operate the boiler. I recently had an Ecotect Sustain installed and I found that the boiler wakes up when opening any cold water tap in the house. The fan starts to spin up, you can see the flame symbol for a short seconds and then disappears and eventually the fan stops spinning. I have never seen or expected this behaviour with previous combi boilers, Is this normal?
Great video and really helpful. We don't have the silver Flexi hose below ours, just a yellow tap with a + and - . Would that be to fill the system do you think?
I realy learned something about heating the right way thank you! I just have the same boiler and sometimes there is a blinking sand watch left from the temperature indicator any idea what that means?
Heyy Mark. I've just moved into a property with one of these boilers & there is no thermostat. Do you know if the boilers come with no thermostat? Do you know if there's any I can buy that would work with this boiler. Thank you.
This is the perfect tutorial for those with an engineering degree. For those of us with mild to full dyslexia and poor retention of systems where pressing the same button does different tasks depending on the data you have retained from the initial instruction... it is mind numbing. The little tap symbols and backwards and forward arrows and ladder with a little Top Hat.... it doesn't make it clear at all. My previous boiler had a thin manual and was clear. This is a boiler for techies, a boiler for call out charges, a boiler that expects all who use it to understand its jargon and a 34 page instruction book.... and why in summer when the heating is off and my Danfuss timer is off to stop the water heating up while away, does it not work when I switch it back on a Friday night when I return only to find I have to use a costly emersion heater to heat my water... and that I can't get an engineer until Monday, that's if there isn't a massive queue of others with the same problem! I have one word for the manufacturers of this device.....SIMPLIFY!
If it was anymore simpler he’d come round and do it for you…. If you can write a well thought out and worded whinge on UA-cam you can slow yourself down and listen to what the man is saying. Stop being a victim and get on with things. ☮️👍🏼
I found it very useful..69 year old female.. I just need to find out how to reduce the pressure bar as mine is higher than that shown . Subscribed for more useful info . 👍🏼
Thank you for the video, so that I know something about my boiler, my timer is not working, what timer I want to buy any particular model please advice.
Amazing video thanks! My boiler has a clock on it and it makes a ticking sound, which is really annoying. We have a thermostat and I was wondering if a qualified person would be able to remove the panel with the clock and replace it with the one in your video ? thanks
My valiant eco tec plus has been off for central heating for the 3 or so months of summer. Hot waters been fine with no pressure loss or faults. I turned the central heating dial last night and it started but the pressure dropped to zero. I hit the flame button while turning the taps on underside and heard a like a loud switch click noise and fired up, closed the taps and pressure dropped again. So I turned the central heating dial off put the pressure back in the system and hot water works and holds pressure but if I turn that heating dial the pressure goes and I get F75. I pushed the pressure vessel valve in and water shot out.
Great video with clear instructions for the “lay person”. Do you have a similar vid for a Vaillant ecoTec plus 624 linked to a Megaflo hw cylinder and an Honeywell EvoHome controller (with no gateway). I want to reduce my summer time hot water temperature.
HI Mark , great tutorial , I have a problem that after the time hot water became cold and time to recover it was advised to adjust Cylinder temperature D006 could you show how to do this ,thanks
If the water temp is set to 55 (for example) but you want your washing machine to do a wash at 60, will it work, or does the water temp need to be at least the temperature of the water you want the wash at?
THANKYOU , i have a vaillant eco tec pro its quite old maybe 2007 and its a council boiler they are extremely reluctant to advise and each time its checked they turn the radiator and water dials up , i have my rads on around 55 to 60 and water is around 44 so not hot but comfy to wash hands without worrying about being burnt , had this since it was installed , the digital dial doesn't show a c at all so does that mean i don't have pre heat or i don't have an option to turn it off and on . many thanks
The hot water tap icon is on my display screen (without a flame) and it is 9am but the hot water is programmed to come on between 6am and 7am. Any idea why the tap icon is on my screen now please?
Hello my minus button and the button above it for the tap icon don't seem to respond when I push them, my water temperature is a bit and I can't seem to reduce it. Could I have locked the buttons somehow?
There's been a few gas engineers out to fix the gas but they can't seem to find a problem. I've got a flashing water symbol that won't go off so I'm stuck with no heating, only hot water. Sometimes it goes off itself and the gas will work, but when the symbol appears, the gas goes off again. Do you have any idea how to turn this off?
Is there a way to turn on the heating from the boiler itself without using the Heat Link? My Heat Link isn’t working no lights on it at all. I’ve tried holding the button down we’re but won’t come on. Any help would be appreciated 😊
Please assist, don’t know what we have pressed, the pressure gauge drops from 3 to 1.3 and continued to drop, How to increase the pressure again? I watched the video, however sorry I still not get it. Please accept my foul and have further explanation to this 🙏🏻🙏🏻
Hello, thank you for the information. I turned off the confort mode as water is cheaper than gas ;) I'm concidering the idea to use an electric boiler of 50 liters, that will be heated with solar energy, that is connected to the cold water inlet of the Vailant ecotec Pro.. Is sthis something that is possibe? So you feed in water at 50°C so the vaillant boiler sences the temperature and just sends it straight to the outlet without extra heating.
Yes, I have seen this as a proper installation. Mains cold into a tank heated by solar panel, then that tank feeds the cold mains into the combi boiler, so the boiler I will not need to fire app if the water is to temperature that the boiler is set to. if the water in the tank is not quite hot enough the combi will heat it to what is needed👍👍. very good idea.👍👍
Hi Mark my boiler have a flash sight of the heating on the screen and it make some noise in the house ABOUT the bathroom and my Vailan only 4 years old is a Eco tec plus 430 can you tell me what WRONG please THANK you.
I was going to clean my filter the one shown in this video I turned the valves off but when I opened the filter cover water kept dripping out I wanted to empty the filter because I was trying to add some inhibitor fernox but when I emptied the filter with a sponge I could hear more water come in does this mean I have faulty valves the ones with black knobs
Hi Mark It's a very interesting and informative My boiler ecotec pro 24 start flashing tab with out running any tab plus gas flame on time by time too what's is happening I am very confused please any help .thanks
My filling loop has an open exit in between the 2 valves, when I open the valve under the boiler, the water comes out of the exit, and doesn't go into my boiler, I don't understand.
Thank you so much. Came home today and no heating. Realised boiler pressure had dropped. The user guide was useless. But your video helped sort the problem out. Very much appreciated.

My boiler technician had me raise the temperature on the tap water. He said it was a better choice if you want to avoid listeria.
Can I just say your a life saver !!! Iv had a pressure issue for days and Youv just got my heating back on !!
Scotland, today it's getting cold now, I'm 70 & scared to adjust my boiler settings. Hot water is easy to understand but central htg what is correct temperature. I live in a 2 bedroom bungalow. Also it's summer, htg off, hot taps not running, my boiler fires up for minutes for no reason?

Thank you so much. Now I know so much more about my boiler. Will be enjoying it being more efficient.
Very good tutorial on setting the temperatures on the boiler. Easy to understand and follow, as explanation is clear and detailed. Thank you.
Been in my house for a while and never really understood some of this so thank you.
Thank you Mark for this straightforward and informative tutorial - much better than the DVD that came with my Vaillant Ecotec Pro 28 back in 2013. I knew most of it but you have cleared up a couple of issues. Well done.
You’re absolute life saver. Thank you for this clear tutorial
Great!! It worked. Thank you fir an easy to follow and informative video. Plumbers in general are no good. They guess and most under qualified.
Thank you. I was looking to shave diwn the gas bill (aren't we all!) and i found this very helpful. I found the heating set to a whopping 75 and the comfort button on... now set to your recommended levels and i can see how it goes. Thank you!

Even the plumber didn't know
It's summer, htg temp room dial is off, hot water taps off, yet my boiler fires up for no reason for minutes?
Many thanks, I've saved money thanks to you, I hope you will keep doing kind of videos😊
Thanks a lot Mark, this has helped tremendously.
Thanks this is my exact boiler though I do have the manual 24 hr time clock as well. I found you when I was looking for how to control the preheat function. You explained it very well.
And thank you so much for your easy video in understanding my boiler its so helpful tgank you.
This is my boiler! Thank you very much for helping me to adjust it and Save ze Moneys ! : )
Absolutely awsome video sir,thankyou,😊😊
Thank you for your video,I am new to these boiler,you have solved my problem.Thank you very much.
Thank you soooooo much how you did explain to the uk public
Thanks again

Thanks so much, helped a lot with an issue with our boiler 👍🏻
Just got a new boiler installed and had no idea what to do so ta!
Thank you for your help today I have hot water because of you
Excellent video, best 'tutorial' I have seen / used on any device
Brilliant this is what I really want to see. Thanks for the tutorial 👍
First at all thanks for this video which I found very informative on how to operate the boiler. I recently had an Ecotect Sustain installed and I found that the boiler wakes up when opening any cold water tap in the house.

I have never seen or expected this behaviour with previous combi boilers, Is this normal?
Thanks Mark just reset my hot water.
Thanks so much Mark, you helped me to figure out how to turn off the comfort function
If only they had a button switch on off for Comfort, that's too easy of course!
Great video and really helpful. We don't have the silver Flexi hose below ours, just a yellow tap with a + and - . Would that be to fill the system do you think?
I realy learned something about heating the right way thank you! I just have the same boiler and sometimes there is a blinking sand watch left from the temperature indicator any idea what that means?

Heyy Mark. I've just moved into a property with one of these boilers & there is no thermostat. Do you know if the boilers come with no thermostat? Do you know if there's any I can buy that would work with this boiler. Thank you.
I’m also in this situation, did you find a solution?
Very Clear Instructions , Thank You
Excellent video, very clear and helpful. Thanks
I have the eco tec pro 28 it was installed in 2012 and it has dials for the hot water and flow temperature
Do you have a video about the other, more advanced options of the boiler? Pump speed etc?
Thank you- I'm getting an hourglass flashing on the display, what does it mean?
Great video, easy to understand. Many thanks for making it simple !

It's said simply & I need simple, but I understand your needs, get a friend neighbour to help you understand Mark's instructions.
If it was anymore simpler he’d come round and do it for you….
If you can write a well thought out and worded whinge on UA-cam you can slow yourself down and listen to what the man is saying.
Stop being a victim and get on with things. ☮️👍🏼

they start ticking as they get old. the clock just pull straight out. any programmer can be fitted
Thanks
Great video, thank you! How do you reduce the pressure if it’s above the recommended values?
Bleed a radiator

Than you for this video but how can we put heating on timer with same boiler .
Thanks in advance
Hi Mark, I have this boiler and your video is very informative..
I have a egg timer on the screen can you explain what and how to remove …many thanks
Eggtimer fine. It's just pump over run
Pump overrun?
May i ask for what?
Boils eggs too? Mine doesn't!😊
Thanks for your video. It was really helpful.
Thank you for this video
Appreciate it.
Thank you so much for the advice

Sorry no video as yet. The Honeywell EvoHome sorry cant help with that only. Only seen it a couple of times
HI Mark , great tutorial , I have a problem that after the time hot water became cold and time to recover it was advised to adjust Cylinder temperature D006 could you show how to do this ,thanks
Love this video
Do you work around London
Well done, Mark!
Mark , any explanation about Boss boiler controller
If the water temp is set to 55 (for example) but you want your washing machine to do a wash at 60, will it work, or does the water temp need to be at least the temperature of the water you want the wash at?
Thank you so much

Thank you this video was very useful 👍
What is the meaning of the “temperature that the boiler is at now” (as shown in the display) ? Is it the temperature of the return or the flow?
Best tutorial.
Hi Mark does the Vaillant eco tec 424 have a permanent on setting?
Good video, but my boiler is slightly different display, and I just wish I could ring someone to ask
Thank you. Useful.
Hello.. how do put the central heating on only without the heating? Really struggling
Thank you Sir 🎩
The hot water tap icon is on my display screen (without a flame) and it is 9am but the hot water is programmed to come on between 6am and 7am. Any idea why the tap icon is on my screen now please?
Brilliant instruction.. thanks
Hello, am I right in thinking this boiler doesn’t have a timer? Thanks
Hello my minus button and the button above it for the tap icon don't seem to respond when I push them, my water temperature is a bit and I can't seem to reduce it. Could I have locked the buttons somehow?
Curious! My comment - that my Vaillant eco tech is *not* like yours, was removed .........
What temperature should I set to heat my apartment? I'm currently at 50°C
When I switch the on button on the for the boiler my heating turns on with it. Which means it’s continuously on. How do I fix this? Thanks
Excelent, thanks mate.
Hai do we need to switch on the main power on button always
Hell the heating is not working using the thermostat or app can I turn the heating on and off from the boiler manually?
There is no mention of the timer symbol? The ‘hour glass’ symbol.
Any plans for a Glowworn Betacom 4 30c?? The plus/minus arrows just say no.
There's been a few gas engineers out to fix the gas but they can't seem to find a problem.
I've got a flashing water symbol that won't go off so I'm stuck with no heating, only hot water.
Sometimes it goes off itself and the gas will work, but when the symbol appears, the gas goes off again.
Do you have any idea how to turn this off?
Is there a way to turn on the heating from the boiler itself without using the Heat Link? My Heat Link isn’t working no lights on it at all. I’ve tried holding the button down we’re but won’t come on. Any help would be appreciated 😊

What if your hot water is on 65 and still not hot enough while having a bath?
I was going to clean my filter the one shown in this video I turned the valves off but when I opened the filter cover water kept dripping out I wanted to empty the filter because I was trying to add some inhibitor fernox but when I emptied the filter with a sponge I could hear more water come in does this mean I have faulty valves the ones with black knobs
Hi Mark
It's a very interesting and informative
My boiler ecotec pro 24 start flashing tab with out running any tab plus gas flame on time by time too what's is happening I am very confused please any help .thanks
Not sure what your asking . You may have hot water preheat on if it's randomly coming on
My filling loop has an open exit in between the 2 valves, when I open the valve under the boiler, the water comes out of the exit, and doesn't go into my boiler, I don't understand.
👍great explained
Perfect ty
How do I off the radiator? Please it summer I need to off it
