immersion heating

[Plumbbob]

I've been asked to replace an immersion heating element , when I had a look at the hot water storage cylinder to get so starts of element it had non on it so I'm not to sure what length to get , is there any way you can tel what length you need without takingIit out, I would like to have replacement to hand so I can be in done and gone

 

[Reg Man]

Is it in the top or in the side of the HW Vessel? What size is the HW Vessel?

mmmmmmmmmm u not nmaking much sense but take a long one and short one with you think they are 27" and 11" normally if it is an unvented cyl, replace with manufacturers own kit

 

[Dotty]

Vented or unvented?

What size cylinder?

Have you the appropriate electrical supply?

 

[Centralheatking]

We always keep short ones in the vans and if nec call back and replace with the right lenght
at least it keeps their hot water on ! CHK

Of course you'll need a G3 ticket if it's an unvented cylinder. For the hard of thinking: remove the thermostats & measure it, stick a straightened wire coat hanger into the thermostat pocket to double check the thermostat length.

why measure thermostat length if your replacing an immersion for a new one

From what i can decipher he is talking about replacing the thermostat

 

[lame plumber]

Bletchley Park did a good job of breaking German enigma code during the last war, bet they couldn't break this one, this is one heading for the album, you know distinctively when something's going to go wrong. No Tamz he said element that's what I though he saidhement

It is an open vented single pipe system . I have never done one before normally taken out and new system put in. I was wandering if there is any relationship between the height of the cylinder and the length of the em erosion heater

 

[happyflyer]

What as the length of an immersion heater got to do with an open vented system, I think others have answered you above.

I will try an easy way for you:

make sure the water is turn off I suggest all the water to the house, cold water stop tap, run the hot water off a the downstairs tap, the lowest and when the water has stopped you should be able to remove the immersion heat ONLY IF IT IS IN THE TOP OF THE CYLINDER, you will need some old towels there will still be some water in the cylinder to the level of the heater connection.

Remove the heater and take it to your local shop and tell him you want one the same length.

Now, if by some chance someone has installed a short heater and the cylinder will take a longer one, its up to you.

Better still do you know a good local plumber, it will take him about 30 mins.

 

[Plumbbob]

I know why your happy flyer . You fly in start the job fly out to get parts. Missing for hours fly back finish and charge the earth.rip off man

 

[Centralheatking]

WRONG - NEVER drain down 1st ALWAYS loosen up the immersion heater with the water in the
cylinder - gently tap your immersion heater spanner with a hammer is good. Then drain down the water. and remove the immersion etc

If you dont an empty immersion is very weak and you can crimp/twist the copper - then its
new cylinder time been doin these for years......... Centralheatking

Thank you

CentralHeating King, Hope when he tries to loosen the Immersion heater nut he doesn't sheer it off, never heard that a pressure of 6ft would tighten up a cylinder that you could swing on immersion heater spanner, I am certainly not too old to learn not that I am likely to be undoing any immersion heaters in the near future, this is a lot of fuss over an immersion heater.

 

[Plumbbob]

I'm sure it is happy flyer but that what they want. And the only fuss is coming from you going on and on . Advice is what I asked for , opinions you can stick where the sun don't shine
