Immersion Tripping RCD

Eh?
The link you have provided shows this system being adapted to be used in home brewing, not that it is an item intended for brewing.

The picture shows it is clearly installed in a plumbing system.

It is a standard immersion heater installed in a small copper sleeve, the small volume of water is heated and then travels out via convection and in to the hot water storage tank. Cold water is drawn in to the small unit at the same time from the bottom of the hot water storage tank.

Now back to the point of this topic: the immersion be broken, replace it or get it replaced.

Edited now (new link)

Why replace the entire unit when you can just replace the immersion heater?

Because it is not a normal element, it's more intricate like a heat exchanger

It is a normal immersion heater! How many time would you like me to say it?

Have you looked at my (edited) link? The company who patented and manufacture the heater (Willis) state that it should not be used in hard water areas - not an everyday element.

In that case you fit an element more suited to hard water.
They are a bit dearer than the standard ones.

Arrrgh, the op does not have the unit featured in your link! He has one which is a copper cylinder with an immersion heater boss at one end and two pipe bosses, there is a perfectly normal 11" immersion heater fitted in to the boss.

Not being suitable for hard water areas is due to the fact it has a copper element. All copper immersion heaters are unsuitable for hard water areas, incalloy or titanium elements should be used in hard water areas. That's pretty basic knowledge for someone doing domestic electrics isn't it?

I realise that incaloy is appropriate for use in hard water areas - my point is that the company advise against this (link) because of its rapid heating quality, not the fact that it's made of copper.
The Willis heater is very common in Northern Ireland (OP location) so why do you think this is not one of those? I read in another forum that elements are a different size/diameter that Redring manufacture before I posted about it being perhaps not standard - I unfortunately can't locate that again (though not necessarily fact).

Oh, and I am choosing not to respond to this part of your post.

I said it is not the heater featured in the link, look at the pictures for a start!

The unit in question here is much older than that modern version, and it contains a standard 11" immersion heater to the best of my knowledge. The last one if those I had dealings with did and if I ever come across one again I'm sure it will.

Now can someone please pass me a brick wall for percussive frustration relief

 

[davesparks]

And the op changed the immersion 2 years ago so I'm pretty sure he already knows what element to buy.

I think you will find it was the stat he changed 2 years ago

Apart from the shiney new label on the one I linked they both appear exactly the same to me
