Hot Water Cylinder Replacement.Help needed !?!

[Fly100]

Need to replace the hot water cylinder cos its just about to start leaking big time..

However I see there are loads of diffrent ones...direct , indeirect , vented and unvented...

So let me discribe my system then someone could tell me what I have.

1 hot water copper tank fed via the bottom from a cold water tank.

The tank its self has the following pipe work outlets..

to the rear of the tank two pipes these feed to the the boiler so im guessing these bring hot water from the boiler into some sort of coil (im guessing this is the indirect part)
Two other pipes are also present...one coming out the top (feeds the hot water taps ) this one has a T in it and an overflow into the cold water storage tank.The other pipe is at the bottom and feeds from the cold water tank.The electric water heater fits in the top of the tank but im guessing thats a standard thing.

Relly the only bit of info I need is what type of system is this Vented or Unvented?

Also the tank im guesing will be 10 years old or so will i need to change the fittings as the threads and sizes might be diffrent??

Cheers for any help in advance.

You have got a vented indirect hot water cylinder

Standard open vented cylinder - measure it and ask in the merchants for the necessary fittings for the tappings.

Remember the insulation adds a couple of inches to the width - quoted dimensions are for the metal - not hte lagging.

Will I have to change the fittings on my exsisting pipe work?

Cylinder is a YorkiLag

Yes it is very very rare that a new cylinder will fit existing pipe work

How can you say what it is ?????
Could be a single feed.
How many cold water tanks in loft or wherever ?

I think OP has given a very clear description of what he has

Read it again and that could be a single feed cylinder...............................

I take your point

 

[Dan Robinson]

By single feed to you mean Primatic?

if so I would have thought that:

will be 10 years old

should eliminate that - I've never seen one that recent anyway.

You don't do much plumbing then

 

[Dan Robinson]

too much...

 

[ollski]

The way it reads is that the op has a cold water tank (f&e) and a cold water storage tank kind of ruling out a primatic. I wouldn't rule them out due to age though I could show you 200 primatics fitted on wau circs fitted within the last 5 years from my window here.
