    Your instructions couldn't have been clearer. You are a total legend, Allen!

    Brilliant easy to follow video. I had my 2 year boiler serviced yesterday. This morning there was no hot water or heating. The gas boiler engineer who serviced it said it was nothing that he had done as it worked when he had left. He said his call out charge was £65. I managed to find the fault which was low water pressure and followed the video. I saved myself some money although i would not have entertained having the con man back again.

    Really helpful video, didn't have a clue how to add water to the system until watching this! Many thanks.

    Thanks a lot Allen for this useful video! I have VITODEN 222-W which sometimes has fluctuating pressure between 0.2 to 0.9 but never going above 1.0. Today I got error F.74 which I believe is low pressure. I did a restart of system and for now it's good but I thin I need to top it up as suggested in your video.
    One question though - how can I vent the system?

    Thanks for this and all your videos, I have found them very informative. I have a Viessmann Vitodens 200, 3 years old, and the pressure guage is broken. I am able to read pressure from a exterior guage, attached to the supply line. Apart from that broken gauge the system works fine. My question is whether I should replace the veissmann pressure gauge or simply reply on the supply line guage. I've sourced the part but my local HVAC wants 8 x the part cost to replace. Again, thanks for the videos. I would never attempt any repairs myself but they at least give us owners some knowledge so that when we interact with the professionals, at least we can understand what they are talking about. Cheers

    Hi Allen, thanks for your brilliant videos. We have a Vitodens 300 and the pipes are set up somewhat differently. For instance there’s no loop connecting the te pipes. Love to have your advice on recharging the boiler.

    • @schez
      @schez 9 місяців тому +1

      Mine is same model also without the loop and I've found out the pressure is filled with a blue key beside the second pipe from the left.

  • @alexandrudicu5212
    @alexandrudicu5212 2 роки тому

    Allen, please make a video with new Viessmann 050w internal components and discuss their quality and what can go wrong and how easy is to find out new parts to replace the broken ones.

    I have a vissemam w100. I had topped up the pressure to 1 but for some reason my taps in the shower and baths only give me either extremely hot or extremely cold water - no in between.. What could I do to fix this? Lowering the temp on the boiler doesn't work

    Hi Allan, general question.
    Have Potterton boiler now, replacing with Baxi 830. Do I need to replace the flue? One company says yes, one says no need... ?

    Hi....I do not have the second black lever valve at all... got the 15mm cold feed one 😕.....open the 15mm cold fill lever and nowt happening. Does the boiler need to activate a valve or something ??...stuck at the mo ....exactly same boiler as shown

    Hi Alan. Where is the drain point on them boilers, if you just want to drop just the boiler to change prv and do the vessel. Thanks

    • @AllenHart999
      @AllenHart999  2 роки тому

      Hi Jason. Thank you for the question. It has a drain off on the left-hand side near the gauge. Thanks.

  • @donien3113

    Any idea why the highest radiator in a house would keep gathering air but pressure not increasing/decreasing (and decreasing only slighty after bleeding). Wolf Combi boiler....

  • @doc9193

    HI Allen , I have a question regarding Viessman 050 , when it gets installed is it necessarily to have that black pump box on the installation or not ? Thank you in advance !

    • @AllenHart999

      not sure what you mean.

    • @doc9193

      You know the black box which is the pump for the system , is it necessary to be installed or could be installed without one

    Hi Allen, would you please do a video on why different size pipes are used, and where, on heating systems, and if specific sizes are mandatory (I was told to use 22mm everywhere for radiators). Thanks.

    • @markfernandes2467
      @markfernandes2467 6 місяців тому

      22mm is wrong on Rads, 15mm is standard & microbore (on newer houses) only uses 10mm or even 8mm pipe. 22mm is more of a heat pump size, but even with heat pumps, 15mm is fine for rads.

    Hi, I only have one black isolation valve under my boiler , turning that one alone doesn’t seem to fix pressure. Any ideas?

    • @jasonsdavison
      @jasonsdavison 8 місяців тому

      Ah I saw another of your videos where the valve was fitted in a different orientation, same as mine, that solved it. Thanks so much

    How is it possible my boiler seems to work perfectly with 0 pressure? It's not the manometer because when I use warm water it goes up slightly, then drops again.

  • @dancer11011964
    @dancer11011964 2 роки тому

    Hi. I’ve put too much water in the boiler so that the pressure is on 2 bar. How can I reduce the water pressure and is 2 bars dangerous?

    • @andrewlittlewood8057
      @andrewlittlewood8057 Рік тому

      Let some water out through the bleed valves until at the required pressure.

  • @bansh3
    @bansh3 2 роки тому

    Dude, on 050 you have a blue tap under the combi on the left side, you close the return tap and open that blue tap, check the pressure indicator and that is all... no fancy plumming.
