I do not believe I am on the wrong site and as mentioned before, we all have free agency. If this thread does not interest, there is no need to be here. This is a positive, educational thread. Negativity and divisiveness is not welcome in my space. I thank you all for respecting the tenet of...

Thank you for this, Harry. Does magnetite only form in the heat exchanger or other parts of the boiler, too? If the contractor does not give the system a thorough flush, and does not add a filter and inhibitor (simply only replaces the heat exchanger), how long do you give this new heat...

I appreciate the good luck wishes.

Thank you, Jeff the gasman.

There seems to be a real issue with my interest in this topic. This site is for people who are interested in learning- otherwise it would not exist. If you are not interested in this topic and do not want to read up on it, there's no need to be on this thread.

I was thinking about when this issue started. Throughout the seven month period with the new pump the weather was warmer. Only the hot water was on for thirty minutes every morning. It is since the weather has got colder and the heating has been switched on, too, that the boiler has started...

Could you please expand Jeff the gasman?

I was very grateful to JonathanM for sticking up for me. He understood why I was here and my purpose and was very respectful towards me and one of the first responders who provided helpful assistance. I also appreciated your very detailed response MeldrewsMate which I have found immensely...

Update: without carrying out any checks, they- not exactly sure who 'they' are- have decided that the heat exchanger will be replaced. Thank you for the information about the low flow. It's very helpful.

I think the challenge is that, as an example, other than the pump being checked on the tradesman's recent visit when the boiler issue started, no other checks were carried out. In and out. Less than 10 mins. Which means none of the observations I've catalogued have been noted and none of the...

Good morning all. I think what is not being understood is that because of inattentive workmanship on the third party's side my time and energy is being consumed chasing up bad advice, followed by bad work, followed by more costs to the landlord because of the bad advice and bad work. My...

Good morning MeldrewsMate, Thank you for this very detailed response, it's very welcome and I know it would have taken time to write. I am not a professional tradesman or even an amateur one, just to assure you that nothing is being touched by myself or anyone else other than a tradesperson...

Thank you, Harry.

Good morning Harry, the list of symptoms is unfortunately not being taken into consideration. The most recent experience is of this past week when the junior contractor came out. This has unfortunately become my problem. I would like it not to be.

Good morning Jonathan, thank you very much for sticking up for me and understanding that I am conscientious alongside my purpose in being here.

Yes, it felt very much blasé at the time. In that case, do these options sound reasonable (if the other recommendations of valve opening/pump speed don't do the trick)? Either: proper powerflush then change the heat exchanger Or: proper powerflush then replace boiler I guess what I'm asking...

I understand, thanks kidgreen61. Is there an easy way for me to check this muck without accessing the loft or doing anything technical? If uneconomical to repair and it has to be replaced, what steps should first be taken about cleaning the system? I worry that a shortcut will be taken, the...

Thank you for your honesty, I really appreciate it. If they turn up the pump speed, and it works, they will ask me to stick with that but it's such a horrific noise, I just don't want to go there. I asked the supervisor if he could replace it with a quieter one when he came out to investigate...

Unfortunately, I have only ever accessed the loft with tradesmen so I am not sure if it is full of water, Mister Banks, and whether the ballcock has failed. I also don't know where the pipe feeding the heating system is and how to check it. This is the part where I stumble- checking stuff...

Thank you, this is a little more technical but I will think it over to try and understand. What I understand, though, is that potentially not enough water going through the boiler could be the problem. How should the water going through the boiler be increased to prevent this? And if this...
