Hello Mike, I have had a gledhill pulsa coil for about just over a year now I’ve had no hot water for about 3-4 days now, an engineer has inspected the boiler and everything seems to be working the boiler does work when I wire my booster switch to the main element as that has power all the time which is great for a temporary fix but it is still not heating up overnight which is my main problem really struggling how to sort this, any ideas?

Yeah they don’t tell you how much energy it takes to boost these heaters throughout the night, it’s like boiling a kettle continuously for 7 hours!

As soon as I let go of the top knob to turn it, the pilot goes out. It doesn't matter how long I hold it in for.

What are you saying?

What does 'you only get one chance at this ' with a laugh mean ?

Love it!

Hi Mike the powermax 155 frequently lock out .heating is working well unless

We have a glow worm boiler. We had a service, the fan went a few weeks later and had a new one fitted. Ever since it’s been making an awfully high pitched noise. Getting complaints from neighbours. Could this be the gas valve from reading previous comments? Shouldn’t this have been picked up in a service?

Whatever made you do these videos, I can only thank from the bottom of my wallet... spot on advice that instantly worked (topping up header tank!!)

Mine is only fitted newly today and is making that noise 😢 and it was to replace a bad warmhaus boiler that gave hassle for two years 😢😢😢😢

Either change or clean the injector and replace the blue o ring at the top of the Venturi, cheapest option at first.

Hey Mike, I'm having issues keeping the hot water going. The boiler needs to be depressed every time before using and then only runs for maybe a minute before shutting off. Just wondering if you had any ideas

Mine is doing this too! It’s only three years old! It’s doing my head in.

Such a great help. Sure enough the spindle was solid. Got a big enough screwdriver in there that would fit the slot & managed to free it. Turned it over a few times, fired it up & now I have a warm house. I thought for sure I was going to need a new pump. The water where I live is hard & I haven’t used the central heating system in more than 6 years, so I’m very grateful. Thank You🙏

Hello Mike. Not sure if you're still there. My Netaheat MKIIF from 1985 won't spark and light the pilot. Any ideas? I can light it manually with the front off then it follows the correct sequence. Do I need a new 'generator ' circuit board? Probably not the PCB box because it otherwise fires up normally when manually lit? Thanks!

Hello, great video. I seem to find both my day and night ones keep tripping after a week. I reset them on a weekly basis. What is the issue? Thanks

Wasn't the gas valve on mine with exactly that noise. Ended up being a loose bafflle plate in the burner unit.

Hello Mike. I have a Boilermate 2000. The heating and the living room thermostat switched off,but the radiators still warm. And looks like the pump spinning,running constantly. Could you help me please?

Hi Mike do you have to have the heating off before you undo the screw

Thanks

Baffle plate inside the burner housing

What is the cause and the solution to this problem?

My powermax 155x makes singing noise like in your other video. If I touch the spinning fan blades, the singing noise becomes lounder,is it a failing fan or the gas valve?

The total rating doesnt add up with your rate 1 and 2 rates. Scottish power telling me that total rate is my storage heating rate ?

Hi just got back from my holiday from plus 30* to minus 2* and fixed my hot water from your video. Very helpful & Thanks. Will call you next time l need a boiler engineer

Thank you! You've saved me with this video.

With Respect! Not helpful In a caravan when it's been off for ages and won't go on!!!

Hello, thank you for explaining. I've moved into a flat with economy 7, when I use my appliances during the day (I work from home) and lights/heating etc is this drawing electricity from the night rate when the tank has already heat up. Or while I'm working from home are my appliances drawing electricity from the day rate please?

gas valve for sure

I so wished you lived closer Sir , my ancient j25-32 Modairflow heating system has a problem, the burner will light for 10 seconds approximately, but fan does not kick in. If I turn the full heating system off on the wall socket then back on the fan will run for a few seconds.

Thanks a lot mate

It’s the bottom thermostat

Thank you! very helpful

Thanks for the video! I have similar pump (model - grundfos ups15-58fc) but it doesn't have the screw and I have to take the whole black cover off to get a glimpse of what's inside. All I see is a metal covering? that takes up most of where the screw should be. Any tips or do I need to take the whole pump apart? I'm thinking the shaft just ins't turning. Thanks!

Do you need to add water pressure to this type of boiler? I’ve never seen one of these before

Thank you for the helpful video. I have followed advice and understand but in the morning I check that if the water is hot but it isn't, do you have any idea what the problem might be?

Hi Mike. I want to thank you and didn’t know how to so here I am on this video because I hope you get to read it (this video is not related to my issue BTW). My vented bungalow central heating boiler pipes started making horrible gurgling, sloshing sounds about a week ago, it started completely out of the blue. It’s been quite worrying, all sorts goes through your mind (expense and worst case scenarios) and I can’t get a plumber out so have been frantically trying to understand how everything works myself because I turned everything off two days ago. It sounded that bad. This morning I found a piece you wrote about how systems work with an idiot proof diagram and issues where the Fill and Expansion tanks can evaporate dry over time with the ball cocks sticking. That’s EXACTLY what I found about an hour ago. I reckon these long scorching summer months haven’t helped. So, I pushed the ballcock down and filled up the tank. Fired up the oil boiler and all was whisper quiet again. FANTASTIC!! I have satisfied myself the ballcock works ok it just needed a wiggle to break the scale off. So, thank you, thank you, thank you. UR a ⭐

Cheers! Fixed my boiler!

We have two of these, damned fine machines both from 1987.

Engineer replaced the gas valve but the same issue reappeared

Hi Mike I'm just trying to find out how to relight my potterton promax combi boiler I have tried to put it back on but the flame will not light can you please help me with this may thanks x

Hello May I ask you? why my powermax 155 burned 3 amp fuse and when I replaced fuse again cuts the power in 30sec. Doesn't show any live. Thank you Thank you

Just moved into new home with same meter as in the picture. Not sure why but it has 3 meter readings plus total ? Also not sure what the orange boost button is for ?

Please can you help me? My ideal boiler is making this noise. At first there is no noise but it starts about 25 minutes after turning on the radiators. I have turned the dial to water only as I am worried about keeping it on with this noise - I assume it’s dangerous to keep it on with this noise? There are no fault codes showing and nothing in the appliance guides refers to it. I have someone booked to come and look at it next week but in the meantime I am very cold. I have rheumatoid arthritis and am recovering from sepsis so I feel the cold very much. Is there anything I can do in the meantime to enable me to put the heating on for a while?

I changed the gas valve and it was good for about a day, so then i changed the fan assembly....and voila! All good. No more loud whining noises

Can you recommend where to get a new fan from

Same here,brand new boiler 2 months old..so annoying..is there anything I can Try myself at home to stop it before I call someone out?

Hi Mike. I had some problems with patterton Suprima HE boiler. It working when he want. Can be a pressure in Radiators? I live in West Barkshire

Hi there, I am really hoping you will respond to this. I live in a council flat. I have had to endure this noise for hours on end every winter for over three years now. The council has sent engineers out to look at the boiler, who waited around for a couple of minutes to see if the boiler made the noise. It didn't, so I played a video of it to them and they claimed that they didn't know what it was, then left. What can I do? Because honestly, by this point, I am ready to just stop using the boiler altogether and give up. I'm getting to the point I'd rather just be cold than listen to this any longer.

Boiler going inwards from left side, told 2 replace it, its 18 years old, can it be repaired?
