Last 3 winters had terrible connection problems with the LP20RF & DT20RF the engineers have fitted new ones of each , re-set the boiler , changed the frequency, switched off and on again , changed batteries no end of times . After 8 years of no issues the last 3 years has been awful . The heating firm has now told me they will either fit a comfort2RF or will install a wired system. I think I'm a victim of technology development... Still at least I have a spare DT20RF & LP20RF in my tool box to look at .

If Mon-Fri is set different to Monday, Tuesday, Wednesday individual days, which takes priority?

Had a new Vaillant at my old home, so much easier to use

Thanks for the video. I almost gave up when I couldn't figure why the key on my Worcester Bosch 25si wasn't closing off the water when I tried to fill it. As instructed the arrow on my key was aligned with the lock marking but water was flooding out when I opened the white tap. Oddly on my boiler it transpires that the key has to be facing me irrespective of where the arrow mark is aligned.? So obviously something different . So if you get the same problem as me follow Aquaheat's instructions but then try what I did.

Whats the use if we cant see the display get closer

Any suggestions for if the display is not coming up?

Top man!!!thanks

Useful video. On re filling my boiler - greenstar highflow 550. I noticed a drip coming from the inlet valve. Is it possible to replace just the filler loop inlet valve without draining the system? (Top filler valve) - Just turn mains off and replace? Thanks

Thanks so much! Saved my (cold) bacon!

Tried this but getting a code 63??

my key just keeps turning it dont lock like that in the video. i used to have this boiler but now i have the newer one with the digital display, but the pressure valve underneath is the same as the boiler in this video. what do i do, just keep turning? i must of turned it about 10 times

Another £100+ saved for this single mum thanks to generous men on the Internet. AND I'm getting quite proud of my self sufficiency! 🙏

Great video, so easy to follow. Gives you all the information you need. Thank you.

Brilliant mate. That's been a huge help today.

how old is this boiler? when did boiler release

How do you turn the hot water off altogether? i need to use the hot fill pipe for my garden hose and I can't get the hot water to turn off

Thank you. Nice clear and easy to follow video which I just used to do the job!

Found this useful, thanks.

I was very struggle with my boiler thank you very much.

I am considering replacing a 30+ year old Potterton Kingfisher RS 50 CAT 1N boiler. The hot water tank iis gravity fed with an overhead tank. Thermostatically controlled power shower require such a tank. Any advice on selecting an external central heating pump and a 3-port control valve? Many thanks!

I turned the white nob beside the key and no water went into the tank, turned it quite a good bit round but was worried I'd pull it out if I turned it to much, but no water seemed to flow so aborted the mission, any ideas why that would be? Also my boiler says pressure low its at 0.9 but the warm water and heat still works so just wondering if that's the reason for the water not going into the boiler? Any help would be appreciated.

Did this in the morning back in the red by dinner time

Thank you 🙏🏾

Thank you. Very easy to follow. Job done.

Life saver 👍

Vvv

Why the temperature is not going beyond 18. I set the temperature for 29 and now the room temperature is showing 17.3 and 18.1 after that it's not going up. What to do ?

I can't see my comment. About a year ago i were here first time and I keep visiting. Thank you so much.

Is there a manual mode in it? I don’t need a programme as I don’t have a schedule

What is the temp dial (the one on the right) for is it for the heating or water

I would like to know what you have to do when you plug the receiver into the boiler how you connect the timer and when you do connect the timer to the receiver how do you get it to come on and go off and what is the life span of the batteries and can you use rechargeable batteries being a disabled pensioner all the technology is overwhelming to a lot of people and not all of them are disabled and a pensioner the old manual timers are far easier to use

How did you take the lid from underneath off so easily? Mine won't come off ! The manual says release the catch and pull forward..I don't see a catch to release anywhere!

Cheers bud 👍

Easy looking, but why don't you specify to turn of the electric switch on the wall 1st( you just said "turn heating off")? Also when I've followed this procedure just now, putting the key to the padlocked position and turning the white nut anticlockwise, I don't hear the sound of the boiler filling nor get any change on the arrow in the red on the clock for pressure increase/decrease. So, back at square one!

This video was of much help. Many thanks for your video. You really simplified it for me.

Top work, slow and clear. Helped a lot.

Thank you so much! Bosch website was telling me just to turn the key, not mentioning the knob!

Doing this on a Celsia boiler and the grey cap just comes off when I attempt to turn it so not able to try and release the pressure

Very clear & helpful Thanks

Thank you , my keys just snapped in the boiler is it safe in there until I have a boiler check ?

My heating has just started not to come on i usually did it manually from the therostat but that is not working, I've noticed the temp to kick the heating on is 5c and I can not change it on the boiler I don't get the option to set the temprature when setting the times, some one plzz help me

Water sign displayNa?

Thank you for this video, i had an issue with my water heating up - i reset all my settings from the menu and it sorted it

Filled pressure back up to 1.5, turned white knob to right, filling key to left, REMOVED KEY, WATER IS CONTINUING TO RUN OUT THE BOTTOM......?? PLEASE ADVISE

I've watched 2 demos by staff so far, and neither tells us how to just switch the radiators on and off rather than putting them on a timer? 🤔 This is frustrating as I just want to know how to switch my radiators on and off when I want them on and off 😒

Was looking for the loop and this man has just saved me hours from looking more and then thinking of installing one 😂 thank you 🤠

The installer showed me, but I'd forgot. Cheers

Thanks so much - was struggling to understand the on/off temperature settings! You made it simple. Cheers.

No Useful Information, simply an advert for installer's company!

Excellent!
