[@barbara7784]

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.

[@JohnM-oo7io]

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!!!

[@scarlett7864]

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!

[@InternallyCoherent]

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!

[@laurasafont3229]

Thank-you Mark, you are a very good boiler tutor!

[@kikitsar295]

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🥰

[@tommylawton6253]

Can I just say your a life saver !!! Iv had a pressure issue for days and Youv just got my heating back on !!

[@stevenolivero5207]

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 :)

[@nohandle-01]

Been in my house for a while and never really understood some of this so thank you.

[@nakhan3658]

Your video helped me a lot on this very cold day. Thank you

[@oliviabfb]

Thank you so much. Now I know so much more about my boiler. Will be enjoying it being more efficient.

[@pcplumber01]

Very good tutorial on setting the temperatures on the boiler. Easy to understand and follow, as explanation is clear and detailed. Thank you.

[@aliciaelhigazi307]

You’re absolute life saver. Thank you for this clear tutorial

[@Johnny-qn7jh]

Thanks Mark you explained it so well Appreciate your time and effort

[@sarasartori6285]

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.

[@fetabrown]

Thanks so much. Moved into a new house and this was a godsend!

[@johnmichaelrichards]

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.

[@christinesmyth5491]

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!

[@sarasartori6285]

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.”

[@deeindu6616]

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.

[@Pye143]

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

[@seltaeb3302]

It's summer, htg temp room dial is off, hot water taps off, yet my boiler fires up for no reason for minutes?

[@bemnettesfay5890]

Thnk you its very help full

[@Minpher123]

Thank you for the reply concerning the need for an engineer. Much appreciated!

[@metincakiroglu5057]

Many thanks, I've saved money thanks to you, I hope you will keep doing kind of videos😊

[@willyfindlay4398]

Thank you , now I have replaced a radiator thermostatic valve and depressurise the system. It seems to be working 😊

[@lizdennis8092]

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.

[@MrJonpeters]

Thank you so much for this. I learnt a lot from it!!!! Keep up the good work 👍

[@migsy2115]

This is my boiler! Thank you very much for helping me to adjust it and Save ze Moneys ! : )

[@seltaeb3302]

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?!).

[@christinestephensoncleveleys]

Excelent, thanks mate.

[@Chris-vc1dh]

Is it a good idea to replace water in my central heating to get better results?

[@lesley-annreay5096]

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.

[@look_its_dan]

I’m also in this situation, did you find a solution?

[@davidtitz2346]

Hi, great video! Quick question, what does the flashing egg timer sign means? Also whe when I have connected hive thermostat, the pressure shot up to 3.1 and the screen started flashing.... Am about to call an engineer, just curious what does the flashing egg timer sign means.... Also, I have the version with the timer. Thanks

[@keverton123]

whats the ladder and top hat for if you press both bottom buttons

[@4amenah]

Love this video Do you work around London

[@nigelpallatt]

Thank you- I'm getting an hourglass flashing on the display, what does it mean?

[@micoko76]

Mark , any explanation about Boss boiler controller

[@luckystrike656]

Do you have a video about the other, more advanced options of the boiler? Pump speed etc?

[@patelharish7752]

How do you sort out the problem of water mixing in boiler

[@Lostanddelirious-qj3tq]

⭐⭐⭐⭐⭐. Very helpful video!

[@SezginYesiltas]

Bu video'yu seyreden herkes gibi birazdan ben de gidip comfort ayarına bakacağım ve hemen off yapacağım :))) Bu PRO'larda SensoROOM bağlantı noktası yok galiba. Aslında onu öğrenmek için gelmiştim. Neyse yarın servisi gelince bağlayacak bakalım nasılmış öğreneceğim. Teşekkürler

[@tajudeen6060]

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.

[@ammukuttu2756]

Hai do we need to switch on the main power on button always

[@barryhalstead5759]

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 ?

[@teamjiri]

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

[@MarkBallardLTDHeatingEngineer]

they start ticking as they get old. the clock just pull straight out. any programmer can be fitted

[@TheFord1612]

How do you open the front of this boiler?

[@sheriefgerges7789]

Great video

[@lazyeejay]

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?

[@dangerscouser]

Perfect ty

[@erwinvaneynde227]

Verry helpfull

[@cnoriga]

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?

[@Noname4now2025]

Hello,how can i change to max power heating ,from service mode?

[@supershah8111]

Hello.. how do put the central heating on only without the heating? Really struggling

[@melwinsunny2321]

Should I off the boiler to save energy or let it on...

[@davidbrewster5309]

Hi Mark does the Vaillant eco tec 424 have a permanent on setting?

[@constructioneerful]

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?

[@ramonennik2536]

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

[@jhansikamal]

How can I start or switch on the boiler when thermostat is not working

[@PreciousOsagie]

How do I off the radiator? Please it summer I need to off it

[@DadandDaughterReviews]

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.

[@1971pippin]

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
