Has my hot water cylinder coil broke?

Fill the boiler up to 1 bar once the cylinder has stopped draining does the cylinder start running with water

Thanks.

Currently the cyclinder is still running at a slow pace into the washing up bowl which I keep emptying. Water slightly browned.

To fill up the boiler I guess I just need to open the cold water isolation above the tank (which will fill the tank again) but t will also provide water to the filling loop which is above the tanke (which I need to use to raise the boiler to 1 bar) Is that right?

Have you got a pic ?

Here you go. Thanks

Open a hot water tap to allow air in and help drain the pipework. (The glugging sound on the video is the clue that this is needed.)

Ive had the nearest hot tap open througout the drainning

This slight flow that has been draining out from a short refill has just finished. Took a long time, and cant help but feel more water than what I let back in the tank just to wash ip up again.

Ive tried tried to do this. Went abit past 1 bar, but in using the filling loop water was coming into the tank anyway and yess it did drain down (hot water tap was open not sure if it was meant to be)

I have refilled the tank completely now, its full but some pressure is returning to the boiler 0.2 Bar to 0.7bar, the filling loop valve is shut.

How can the CH pressure increase by filling the DHW tank if they are separate systems? Is this not a sign that there is A breach i.e. coil split/perforated

So you filled the ch sys to 1 bar then opened / left open the cylinder drain and water came out and the boiler pressure went down ?

 

[Dave18183]

So, the tank refill was complete, central heating and hot water


I’ve still not opened the filling loop to fill the boiler/central heating system but the boilder pressure

So you filled the ch sys to 1 bar then opened / left open the cylinder drain and water came out and the boiler pressure went down ?

yes, as above. Ive tried tried to do this. I did go a bit past 1 bar in filling back, but in my configuration, opening the filling loop and the col water valve (on the picture I put that you asked for) water is also going into the empty tank at the same TimE (not sure that is what you intended.

I began to drain the tank/cyclinder, opened a hot water tap to let air escape, drained the cylinder totally and the pressure at the boiler dropped to as it was ealrier in the day when emptied (about 0.2 bar) the water was a little discoloured.
