Thank you so much but I want to try and make the system like it was before So far the installer did the following mistakes 1) Restrict the pipework by putting a stupid bend around when there is in fact space for it to drop and enter in the cylinder without any movement of cylinder 2) Use a...

God I feel your pain - That must have cost a bomb to fit - I m sorry I do not have much to add but these Viessman are meant to be the best of the best

I tried to understand this as well about pumped system but did not get a crystal clear answer - First I thought it was airlock then I thought it was pipe being restricted - As well i dont know whether my system is pumped or hybrid so when I speak to engineers I can at least tyr to introduce...

Thank you - Just to repeat myself - The previous owner must have spent thousands installing this - I ve never seen big bore pipework like this in a house On the boiler is a British Gas ticket so this must have been installed by BG many years ago when engineers at BG were the rolls royce And...

MNW67 - Yes that is my picture...Wish I could repipe it but cant at the moment afford to

Yes that is my system - I tried to lay it out as best as I could 1 flow and two returns

DP is almost correct There is one flow pipe (28mm copper far right which then connects into 2 inch / 3 inch steel pipe) for the whole house and hot water. Pump is on return - The magnafilter only cleans half the return sadly There is one dedicated return for the hot water cylinder which you...

Thank you so much. Is a more powerful pump in place of what I have at the moment (dab 65/130) swapped for a 8m head also not an option. I asked before and I was told no. I want to double check this. In my mind the water must be flowing quite fast to climb another floor so should be able to...

Thank you dp and the others. It is so difficult to accept that I have wasted hard money on a cylinder and plumbing I am sorry to repeat myself but this is the final time I ready the question. If I rebend the pipe after the two port valve so there is always a slight fall will gravity push it...

Hi - I read your post a few times and I understand the principle of hot water rising - But I am not experienced as you If the cylinder was gravity is it not the case that the hot water from boiler would flow around teh coild in cylinder and be pumped back through the white pipe? Therefore I...

Hi - Is brown water from magnaclean not the result of sludge and dirt from old steel pipes in the house? Raising the cylinder would achieve what exactly?

Thank you - I will be asking someone else to do the task but not many people understand the system as its complicated I had people suggest an unvented cylinder! And also a combi boiler so I want to make sure I know what to ask them to do The 2 port valve was always there even before the...

In Thank you - I am just looking forward when the flow will go through the cylinder - The two port valve should switch on when temperature is achieved and avoid boiling water in the cylinder That is the reason it is there surely ?

Thank you dp and harry. @DP did you suggest removing the two port valve in its entirety ? Isn’t that necessary to shut off when water is at temperature ? Or as harry suggested after the two port valve ?

@DP - If you can share any thoughts I would be really grateful - You seemed highly experienced and I hope the further picture of the cylinder would help What are my options at this stage? 1) Is a pump after the two port valve the only thing? 2) Rebending wont work - Is that certain and not...

Thanks - I thinkI am so close to finally understanding my system - Would be really great to get a handle on it I think its pumped up the flow and then gravity drops to downstairs radiators because I can see in the loft the pipework being run at an angle to help wanter flow It has caught...

In my small brain (and I know nothing) I have fully pumped system by virtue of pump and big bore pipework - I know this is not straightforward but I feel likely to get to th ebottom o fthis on this forum rather than with engineers who will suggest repipeing house : ( I really appreciate your help

A very solid explanation - Thank you - The boiler has one flow pipe but two returns - The hot water cylinder has a dedicated return pipe straight to the boiler - I am 100% sure of that There is one shared flow pipe and one return for hot water and one return for radiators Does that change...

Thank you - I think this is my problem - I do not know the terminology used for my system to research what I can do - I wish I would have repiped the system in 22mm speedfit pipework but I have just redecorated the whole house sadly and I dont have the money left to that - I wanted to change...

If it helps to narrow my options this is the old culinder I am confused because I thought I have fully pumped already. I have a pump on the boiler return which shoots water up the white flow pipe and the hot water is the first tee of that Would a more powerful pump replacement make any...
