Heatrae sadia Immersion thread???!!!

[armyash]

Ok got sent to a job today.

Horizontal cylinder in the loft, leaking from immersion and going through the ceiling in to the room below.

Someone had already been and told me i need a 27inch standard immersion, picked one up this morning and went to the job. Drained the cylinder and removed old immersion.

New one would not go in at all, i thought i was doing something cack handed as i was screwing it in from the side of the cylinder and perhaps it was the weight of the long immersion causing me issues.

When i put the immersion in to the cylinder it's hitting the 'coil'. and cannot get it to even grip on the thread and screw it up. It's not actually a coil though, it's rows or columns along the top of the cylinder as it lays on it's side. The old immersion end will screw in fine but i can't check what shape it was as it's completely smashed to bits.

Do the Heatrae Sadia immersions have a different thread to standard Immersions? Must do surely.

Anyone come across this problem before?

If it's an unvented I'm pretty sure you need to use the brand specific immersion

manufacturers part required.

As above. I've been on the phone to Heatrae Sadia about other things and they're very adamant on what parts needed to be fitted.

Never seen an indirect horizontal made made by heatrae sadia? Was it one of those horizontal multipoint water heaters they do?

Bet that was a pain having to refill with the old one fitted lol!!

I left it drained, nobody drained it on the last visit so he has had water coming through for 3 days. He was very calm about the whole thing.

It's not unvented.

I didn't even look at the brand of cylinder but the old immersion was heatrae sadia. I have had jobs before where if replacing a heatrae saidia immersion then it should be another heatrae going in. Was just wondering if anyone knew that the threads were slightly different because that would confirm it.

This is the best matching diagram i can find

Where the immersion goes, it is raised.

Where the 'coil' is positioned it would explain why the immersion kept hitting.

Could try putting a shorter immersion in would take a little longer to heat but as it stands custard has no hot water at all at the moment .......regards Turnpin:smile5:

That's what i was thinking. Might have to do that, he probably doesn't use the immersion that much anyway so can always heat it off the boiler.

This drove me nuts today.

Just been looking on the website and it's saying 11" for horizontal, will go for that.
