@dwynwen as I thought it goes nowhere.  Very diligent of the installer to insulate it!

Please let me know how you get on with reducing the hot water.

I think I have asked abut all I can re the washing machine.  I did suggest you disconnect the hose and see what the pressure is like by putting it into a bucket.  That would probably be my next step as it will likely tell you whether its the w/machine or the feed to it thats the problem.

re the noise is something vibrating on the floor upstairs or is it coming through the pipework.  I think you need to try to eliminate some sources.

 

Re getting the the heating working again, once you have read up about it if you could post

1. A picture of the handheld thermostat

2. The current values of all the 'Field Setting Values' starting 20 which you will have in the installer settings screen, the meansings of these are described on page 26 of the second (Samsung) manual referenced below, but for now we just need the values.  You may need to enter a password which is probably 0202. 

 

If you can do this I can provide a process to set it up to run efficiently (hopefully)

 

(Incidentally I think this is the Joule dumbed-down manual for your system, which we may need to refer to in conjunction with the Samsung manual because Joule (suppliers of the cylinder and I suspect the whole package) have, unfortunately,  added some of their own electronics)

 

In case you haven't got it there is a very useful Samsung manual here https://renewableheatinghub.co.uk/forums/postid/11828   This explains all the intricacies of the installer settings.  You dont need to know them all, but the ones on pages 26-29 are key.  Samsung manuals can be confusing to say the least so, if you understand it first time (or even second) I will be jolly impressed.  You don't really need to understand it at all, just be aware of it.

Hope that helps please post back with info/outcomes.  Given what you have told us about your background you can easily nail this, it just takes a bit of time to understand but once you do understand it its really quite simple.

re the noise is something vibrating on the floor upstairs or is it coming through the pipework.  I think you need to try to eliminate some sources.

It might be a pipe bracket transferring vibration into a floorboard.

Simply touching the bracket with fingers would cause the noise to change.

Once we have more idea of

  • the source of the noise
  • how it's being transferred/amplified

... I can then suggest remedies.

Solutions tend to be simple and straightforward.
You are unlikely to be facing much in the way of costs.

Save energy... recycle electrons!

@transparent I have this issue but all the pipework is under the water cylinder if the pipe touching the brickwork isn't the solution as we have already discussed. 

Fingers crossed this year I get to the bottom of all of it 😅

Your insight is invaluable

UPDATE

After another many more weeks someone is finally coming round today. 

They emailed me 30 mins prior to the appointment....... Luckily I had a day off. 

Seems they didn't want to sort it out as they had jobs on making money instead of sorting their existing customers problems out.

Will update on what that means afterwards.

So today went well 😁👍

1 lad came round to check things I have mentioned before.

Then later 3 lads come round to sort out some minor issues

I now have a warm radiator that was previously always cold.

They performed a massive system flush.

Auto air bleed valve that was leaking since day 1 replaced.

Pipe going through wall fully insulated now instead of concrete touching copper. 

To be continued
