I neve thought I will watch an entire video about a boiler, but let me said, thank you so much. It did help me pretty much. Thank you very much. Very helpful
Very useful to know about eco mode! I was wondering why my boiler kept firing up at random points of the day (and night). I have an electric shower so don't need much hot water so this will definitely save me energy!
Your videos are Sooooo helpful. You should do a video for all new boilers, to explain the lowdown on them in your clear and concise manner for the user. Downloadable and of course for a fee. Be worth every penny. Better than any poorly worded and written user manual. Thanks for your efforts.
Thank you for showing me how to turn the eco mode on, I wondered why the boiler made noises all the time and it's only me on my own so there's no point having it do that amazing thanks
Thanks That was brilliantly simple to allow me to warm up & have a shower on a cold day. The explanation was also interesting and crystal clear : And a reminder that my service is a bit overdue !
Thanks. Great helpful and clear video. Had an F.28 error which indicated a frozen condenser pipe. Sure enough insulation had come off. Defrosted pipe with boiling water, reset boiler as you showed, and all working again. Thanks.
This video helps a lot. It's annoy when I try blow radiators because the air in them . Boiler loosing pressure so I can't properly sort the radiators . They are not hot as they should .(Some half way cold ) And this increasing using gas and put my bill up because heating need to be some days all day long because room are cold .
Really clear instructions, but my boiler just displays 'no' when I press the + or - buttons. It also won't let me switch off eco mode, nothings changes when I press both for 5 seconds. It is the Ultimate 30c, but identical control panel to this one.
Thanks so much, Mark! Had my radiators come on whenever they want while on ECO mode, and with the hot weather coming, need to be in full control. Thanks for the clear explanation. Take care! :)
Key point for people whose Glow Worm boilers come with a timer on the right: If the little round switches are outwards, it means the boiler will come on at that time.
I've a Betacom4 30c, no eco symbol pops up when I hold down the plus & minus buttons, perhaps I don't have that feature, never really looked at my boiler since it was fitted a few years back, just now checking it out, out of shere boredom lol
Thankyou Mark, Thanks for your description of the eco setting and related noises from the boiler. I now understand that when I turn on the hot tap when the central heating is also on I get those noises. I can now relate this to my wife and possibly save my marriage. Phew ;-)
Thank you so much. this was brilliant. Ive been trying to find how to adjust radiators. They were red hot and were set to 72. i have been able to lower thanks to this
Thank you very much I thought something wrong with my boiler but it s turned out that I accidentally touched the mole button so heating icon disappeared so I’ve hot water but no heating . Now I know why . Thank you very much .
Magic intelligent and helpful!!! Tap positions when increasing pressure was tricky as difficult to see and tap positions was confusing. I assumed "in line" with pipes would be correct for "on" but no way of seeing pipe direction as its more like a " knuckle "but your pic of black taps being horizontal prior to adjustment helped big time. Yellow knob being vertical during use was noted also it only has a + - icon Glow worm manual diagrams are not colour coded or easy to interpret as they are small and complex to understand even with a magnifying glass and wasn't much help. You saved the day after a F28. Still getting a service though as you mentioned it was a gas issue. I had to bleed radiators to lower pressure from 1.9bar to 1. 2 bar when not firing because I overdid the pressure increase method initially. Would 1.9 bar for 30mins damage boiler during resting mode ( ie) no taps on or radiators? Many thanks.
If your boiler says ‘no’ when trying to adjust the flow temp the way shown in the video, you can only adjust it by accessing the diagnostic codes. Hold mode for 7secs. 00 will display. -/+ to 96. Press mode to confirm. d.00 is shown. -/+ to d.71 then press mode. -/+ to your desired temp. If you allow the value to flash for 3 secs the setting is automatically confirmed. A tick will display for 1 sec. Press mode for 3 second to finish. This is all in the installation and maintenance instructions manual 😊 Hope this helps someone.
My mother has this exact type of boiler. The heating water is set to 70C. But when we try turning it down the display just shows 'no'. The house has a ClimaPro2 controller which I think means some of the settings can't be changed on the boiler. Glowworm came out and were totally useless. Completely daft as the house gets far too hot, but we've never been able to find anyone that knows how to adjust the heating water temperature.
@@astralgary. We gave up with the ClimaPro2 controller. This controller is just useless junk (suspect it was a freebie that the house developers went for). My mum got a conventional thermostat controller installed this year and it has transformed things. Boiler heating water is now set at a sensible temperature and it no longer runs at 'nuclear heat'. Hope you get it sorted, but I think the best (only?) option is to bin the ClimaPro 2.0.
This is great - so much clearer than the manual. Only thing that isn't working for me is turning off the eco setting. Pressing the plus and minus button together is doing nothing.
Hi great video thank you. Have just moved and have this boiler. After seeing this wanted to check radiator temp as room never seems to warm. When I had radiator icon on only I tried both plus and minus buttons and both just say 'no' in the display. Not even giving the current temperature. Any ideas please? Thank you 😊
The manual for some models says "The preheating function is made available by a suitably specialised installer." Which suggests to me that some instalations may not have the ECO mode enabled.
Great vid mark. One Q though, my CH temp is displayed and I’ve reduced it to 65 from 75 but can’t seem to access the water temp section (the book doesn’t help either) GLOWWORM EASICOM 3 25r
Do you have a thermostat by any chance? I had the same issue. If your boiler is linked to a thermostat you can adjust the water temperature from that thermostat - You can also call the glowworm hotline, they can talk you through the menu as I had to with my glowworm for the flow temperature. you need to press the buttons in a certain order if you want to do it directly from the boiler
If anyone has had this problem with their boiler ECO mode not turning off even after holding plus and minus it’s because your hot water Temperature is set below 55c and it has to be 55 for ECO mode to be off then if you try eco mode with plus and minus it will work with plus and minus
Yes i had exactly the same problem. I was told the temp can be set to 40 and still be able to turn ECO on or off but i could not do this but when i set it to 51 it went off. Only if i adjust back to 40 then ECO will stay on.
Thank you Mark very helpful and unfortunately Glow warm brand is not so reliable it takes too long to heat the tap water anyway I will have to replace my boiler after 3 engineers trying to figure it out and replacing parts there is no solution in my case I like instant (less than 30 seconds to have hot water) Tks a million for the video 👍
Thank you for the video. I'm trying to turn down the hot water temperature. For some reason this doesn't seem to work for hot water though. I cycle through the modes to hot water and then press '-' and nothing happens. It's fine when I select the heating. I can adjust this fine. Just not the hot water. Any ideas why this would be anyone? Thanks again
I am unable to edit the temp of hot water . Whilst the boiler pressure bar is displayed , I press once and that shows the water icon. If I edit the temp with + and - nothing happens. press the mode button I can see water and radiator icons .if I press + and - then I can set the temp of radiators . So wondering how to adjust the water temp ?
@@tomray3590 hello! I did some research around this . This boiler is a condensing system and relies on hot water tank (megaflo) for boiling water . The megaflo has a screw to adjust thermostat underneath the grey covers. This adjusts the hot water temp. Note- The hot water tank should have a minimum temp of 55-60 degrees centigrade to prevent the growth of legionella and other pathogens . Ours was set to 55 degrees C by the installer.
The internet amazes me how there's practically a video for almost any problem. Thank you for making this video! You legend.
I neve thought I will watch an entire video about a boiler, but let me said, thank you so much. It did help me pretty much. Thank you very much. Very helpful
Brilliantly clear to those of us who aren’t experts in boilers. You give confidence to make the adjustments necessary. Thank you.
Thank you Mark. You made it so clear for me. Really grateful to you for making things so clear, and of course saving me money.
As a woman in her own, I know understand my boiler! I can manage the basis problems. Thank you
Thank you Mark.The manufacturers should be asking you to write their instruction manuals. Your videos are great.
Thanks Mark! This was extremely helpful!
Thank you Mark. As others have said, so much clearer than the manual, watching this was time wells spent.
Brilliant video. Clear, concise and really helpful. More helpful than the fitter who put it in!
Very useful to know about eco mode! I was wondering why my boiler kept firing up at random points of the day (and night). I have an electric shower so don't need much hot water so this will definitely save me energy!
Thank you so much! I went to go do washing up and found that my hot water had gone. You have rescued me from a cold shower in the morning.

I've watched a couple of his videos and they have ALWAYS helped me out... cannot fault him 10 out of 10 THANK YOU
Thank you Mark.
We have this new boiler today and couldn't figure out how to have hot water.
You save our lives!
What a blessing that you are to all us homeowners!! Thank you
Thank you for showing me how to turn the eco mode on, I wondered why the boiler made noises all the time and it's only me on my own so there's no point having it do that amazing thanks
Thanks for the video got the glow worm 25c installed and still used your tutorial. Done a great job 👍
Thanks
That was brilliantly simple to allow me to warm up & have a shower on a cold day. The explanation was also interesting and crystal clear :
And a reminder that my service is a bit overdue !
Thank you so much. You have saved me having to call out an engineer. The way you have explained everything makes sense and you have saved me money.
Thanks Mark saved us having cold showers this Christmas. Bleeding the radiator knocked off the boiler.
I just had this boiler fitted & made the changes you recommended. Thanks
Thanks Mark. A comprehensive guide to the control panel. At a perfect pace too!
Thanks. Great helpful and clear video. Had an F.28 error which indicated a frozen condenser pipe. Sure enough insulation had come off. Defrosted pipe with boiling water, reset boiler as you showed, and all working again. Thanks.
Thank you Mark, you spoke clearly and simply, I gave. Geeked my temperatures all good, and reset my boiler
Now I finally know what the eco mode is doing. Thanks Mark.
Legend, thank you! Snowy night and husband is out, my and my little one nice and warm now :)
Many thanks for this easy to follow guide. I am now trying ECO and will report back!!!
Thanks mate you just saved the day❤

Very informative. I'll check my boiler settings in the morning.
Key point for people whose Glow Worm boilers come with a timer on the right: If the little round switches are outwards, it means the boiler will come on at that time.
Simple clear instructions for everyday people. Thank you.
Thanks for this Mark you just saved me the cost of a callout. Skipper
Thanks for the advice.. have a Glow Worm 35C and its a great boiler.
Thanks, finally able to turn on eco mode. Can’t waste gas at these prices

Not sure if anyone will see my comment but I cannot adjust temperatures as when you press plus or minus buttons it says 'no'!!
Did u managed to solve this problem I also facing the same.
I have also got that "no" problem for 3 months now...
Same here as well. I think it’s something to do with the installer’s code.
Me too I have the same problem
I have the same issue with the No
Thank you Mark
You are a start save my day the best video on TH-cam
Thank you Mark this has helped me become a adult
Thanks, very helpful and easy to understand.
Many thanks for explaining how to toggle the Eco mode, as this doesn't seem to be documented anywhere (not even in the manual).
This is so helpful thank you so much Mark

Brilliant thanks mark

the eco setting seems to be a bit random. Not got to the bottom of it yet.
I’ve had the same problem here too I have the BetaCom 4 it won’t turn off with holding plus and minus button together
Your boiler water heat is set to 50c or lower it has to be 55c anything below that will turn on ECO mode
@@AgentRidge how do you change the water temp. My betacom 4 just says no when I click on the +/- buttons.
