Thank you for this and your other videos I have viewed, Mark. I struggled to correctly adjust and customise the settings on my boiler despite following the manual. Your precise and clear instructions and excellent accompanying videos have made the task easier.
Thankyou so much for your help. It’s the Christmas bank holidays, the water pressure in my boiler flashed f22 and my home was freezing. You’ve helped us stay warm and happy 🎄🥰
This has been so helpful since moving into our new home, thank you - the comfort setting has been costing us and didn't even know about it. All I need to do now is find a user manual for the Danfoss RX1 box underneath it - no idea what this is for or how to use it!!!
Great video, very useful. .I have the EcoTec Pus 418 but no comfort setting. The manual does not cover Comfort either. Looks like you dont reply to comments but if you did that would be useful . Thanks again. Easy to understand video, well presented
Excellent , and easy to understand. I have to admit, that my Vaillant ( this model ) has not been as reliable as a Rolls Royce, which is what i was told, this brand was. Regular servicing didn't seem to guarantee performance or reliability.
We keep our central heating temperature at 50°c and it slowly heats up the house just fine, we simply had to adapt our thermostat timings so that it can have more time to get to the target temperature
Great video. At night I've noticed the boiler seems to fire up every 20 to 30 minutes for 20 to 30 seconds at a time. Why is this and can you turn it off.
This is a very good video! Thanks! I have a question. On our vaillant thermostat in our living room the display says it’s in summer mode. But if I check the boiler there is no “umbrella” summer symbol. How can I change it to winter? I can’t change it on the thermostat. Thanks in advance.
Thanks for this great video. I have one question about the settings though. When following your instructions on saving temperature settings, my boiler (Ecotec plus) does not display OK and cancel on the display at any time. The temperature display continues to flash after changing it. if I press the right button it just goes to the comfort setting. If I just leave it to set itself, it never does. Am I missing something?
Great video and it help a lot to work in this boiler. Mark would like to ask you, how we can take the spanner symbol off in this boiler? Even when they are serviced or have been serviced they like to show spanner symbol and it is nightmare take the symbol off. Could you help me or us in this with One video showing the process? Thank you very much
Firstly it is a combination boiler? Do you have 5 pipes coming off the bottom of the boiler? if you only have 3 then you have a different boiler. You probable have a hot water tank. If so you need your boiler central heating set to 60 degrees. Also check the thermoset on the hot water tank. Should be set between 50 and 60 degrees.
My central heating turns itself on at all hours of the day, by itself, sometimes turns itself on at 3am. Once comfort is off, will this also stop? Thank you in advance
Us too! Our lowest temp seems to have been set by the previous owners engineers to 15°c. Does anyone know how to lower this? We don't need it st that temp when we're not in / at night.
Very knowledgeable video very well explained we t have this boiler but it seems to take an age to heat our radiators up the digital temperature numbers take an age to climb is there a reason or this our friends have the same and it heats up in no time its like our boiler stops and starts constantly can you give any advice please .
On my Vaillant system the hot water cylinder tank in separate in the garage. It’s heated by gas but is wired in also. I wanted to see the cost difference in heating on electric instead of gas but switching on the electric feed to it seems to make no difference to the gas usage. Do I need to tell the system to use electric instead of gas for the hot water?
Wow very nice video you are professional engineer 😀 can you please kindly help me on my vaillant ecotec plus 837 R1 on central heating the boiler does on go on low flame at all ? It's just goes to high flame 🔥 and cuts out to the set heating temperature ie 60°C and cuts out then the temperature drops down to 34 °C and then its start again its keep on doing this the central heating system works fine and the radiator gets hot but the boiler is not going to the low flame? Please kindly help me on this issue waiting for your reply Thankyou
I wanted to ask what is probably a stupid question, I usually turn the heating off, this time of year from the wall controller, how do I do that on the actual boiler??
Hello how much could cost new boiler installation ...we have pump now..and pump is in second floor. we think to buy in 3 bed house with 1 bathroom vaillant eco tec 830 .we wish to do vertical output.... and do your company do installation in basildon.... Thank you... Kind regards Jola
Hi, thank you for the video. I recently bought a Vaillant EcoTec plus boiler which has been set to weather dependent mode by the installer. At the moment I often have the problem that due to this setting, the temperature of the target flow is rather low which causes the room to stay half a degree below the setpoint while the pump keeps going. After a while the radiators are cold but the pump is still running because the setpoint isn't reached. Could u tell me how I can switch the control to a fixed target flow temperature like u use in the video? Thx in advance!
Hi Mark.. my boiler is vaillant ecofit pure. Need to pressurise but the valve is very tight and will not turn....😢..the hot water valve. Please anyway to loosen the valve so I can turn the know. Thanking you in advance
Hey my friend. I had a problem with low pressure but managed to sort that and increased the bar. I have hot water but no heating. My thermostat light isn't even coming on. I was thinking no water is going into the radiators.....any advice would be great
I have thus bouker but I don't have a tap sign on thw boiler anymore so I cannot follow tgise insyructions. How to make both option, tap and radiator, to c9me back 9n display.
I don't have a tap symbol on my boiker anymore. I use to have bith radiator and tap as in this video but tap symbol disappear, So I cannot follow this instructions. How can I bring it back and follow those instructions?
Excellent video, thank you. I had this boiler installed today along with the hive thermostat. I had to go to work with the engineers still in situ so I can’t prove if this worked. I set the boost function 45 minutes before I went home, and sure enough the heating was on. However, I can’t switch the heating off with the app or the thermostat. After watching your video, the only way I can switch it off is by setting the boiler temperature. The black radiator symbol is flashing. (As a footnote, they had to remove cupboard covers to enable a proper installation and they asked me if they would like to dispose of them. When I came home, they were still there along with much of the other waste that they should of disposed of). Your assistance would be much appreciated.
Hey, I don't seem to have 2 handles on the bottom of my boiler, nor is there a braided wire anywhere else on the system. I can however open 2 valves with a screwdriver, but the pressure doesn't go past 0.2 bar. What am I missing?
My Vaillant ecotec plus doesn't have loads of pipes and valves underneath. Just 2 thick pipes with a blue and red big knob on the pipes.. i tried switching it the other way but nothing Happens. So how do i top it up ???
Hi mate love the video just a quick question pls in my display on my valiant boiler the radiator sign is flashing all the will heating is on is that normal?thanks
Hi we have this boiler and today the heating is working but no hot water. In fact there is nothing on the left digital display. What could that be? Thanks
I have a EcoTec Plus 837. The rads are not getting hot enough after changing the thermostat. The flame candle on the left hand side is really low. Any ideas what it could be?
Hi, great video. Can you please tell us what those numbers 0,8 3,0 are under the bar pressure? ua-cam.com/video/cnwJZYNQoh0/v-deo.html Thanks in advance.
Amazing explanation. 👏 very easy to understand, saved me calling out a plumber/ gas engineer. Thanks so much
ABSOLUTELY BRILLIANT 🎉THANK YOU my shower was set too hot when installed but have adjusted it like you say and now 🤞🤞🤞it is not too cold 😶❤️👍🤞
Very concise and clear!! Thank you
Came here to find out why my heating wasn’t working and learnt a lot more in the process!!

What you video didn't do very well though was give directions to the donation box!
Thanks, very helpful!
Thank you! This is so helpful :)
Amazing, thank you so much
Should you not always have your hot water at 50 degrees to avoid bacteria like legionnaires?
Omg such a helpful video. Thanks soo much. 👏👏
Thank you 🙏🏾
Very informative
Super clear thanks!
How do you reduce pressure? Mine is at 3.2bar and flashing.
Thank you for a good video

Mine don’t have a tap
Can anyone help, I don't have the tap Icon in the display. What do I need to do to get it back?

Hey Mark, how do you bleed the hot water heater if there is too much pressure?
I have thus bouker but I don't have a tap sign on thw boiler anymore so I cannot follow tgise insyructions. How to make both option, tap and radiator, to c9me back 9n display.
This boiler is connected to a device that sends a WiFi signal to the thermostat does this burn a lot of energy?
I don't have a tap symbol on my boiker anymore. I use to have bith radiator and tap as in this video but tap symbol disappear, So I cannot follow this instructions. How can I bring it back and follow those instructions?
But I came here to see why I've got very high pressure, like almost maximum, how to reduce it
Same problem, why explain how to increase pressure without explaining how to reduce it?
I have the same problem it was 3.6, just bled a heater and reduced it down to 3.0
Now my boiler makes a noise when any hot water tap is turned on
@@tapen678s6 did you solve a problem? I have also high pressure but a i dont know why its hapening?
@@azathioprine3852 there is a expansion valve inside the boiler I took some air out 👍
Is this the same for the vaillant ecotec plus 615.. the display is different. 😊
I am afraid not. If you have a hot water cylinder then you need to set your heating thermostat to 60 degrees
@@MarkBallardLTD thank you 🙏🏿
Hello, i have the eco plus the same model as this but i have to put water on it every day cause always the water finish... what i can do ?

I have a Vaillant eco tec plus 418 . It only has one tap , how do I set about balancing it ?
Hi Mark, any ideas about why my thermostat keeps working or not working - even after new batteries ? Eco tec plus 837 boiler model.
How do you change mode on a Vaillant ecoFIT pure 618 non combination boiler ?
When I press the radiator button the display goes straight to pressure and doesn’t allow changed to the heating temperature, why is this?

Vaillant rather than vailliant😂
The worst boiler ever. Every year for 20 years it takes days to turn the heating off.. Please re-invent the on and off switch.
