Hi all
I've just spent ages looking at what I've got - and I think its all
clicked and I understand it. The cylinder has 4 pipes (excluding
pressure/temp releif) - boiler in/return; cold feed and hot out.
The boiler in/return is linked via an electric valve to the heating
system, so this circut is under about 2 bar pressure controlled with
its own pressure vessle/release valve.
So - I reckon I could loop the boiler feeds, and put a stop-cock on
the cold feed and the hot water out. This would mean I could have
cold water and heating and not worry about the cylinder - and okay -
no hot water.
In which case, I'd be 100% confident of ripping out the cylinder
without doing any damage.
Assuming a replacement of a vented (aka thermal storage) system - from
what I've found on the web, I'd just need to connect up the right pipe
to the right hole and I'd have hot water again. Is it as LOGICALLY
easy as that? (I know how to de/repressurise the boiler/heating
loop).
Any comments welcome, and I've got a few more questions below. Don't
worry about running before walking, I never jump too quickly! Also -
if I'm right about the issolation bit - its okay as we don't need hot
water as we can go to the local swimming pool for a swim and shower
every day!!! 
SO I can take my time!
Some questions if I may be so bold
1 - is my understanding logically okay?
2 - any recommended systems / suppliers (UB or SL area)
3 - do systems normally come with all fixings and instruction
manuals!!!?
4 - a phosphor de-scaler was noted in this thread. What is this and
where does it fit?
5 - whats the thing I have on the boiler feeds on the tank. Red thing
with long white wire. Is it a flow switch? If so - whats it for and
whats its current purpose?
6 - any recommendations for websites to look at appreciated
You have all been unbelieveably helpful - and are giving me some
confidence to undertake this (only replacing with the storage type!!).
IF I could get a plumber I'd be happy to pay, watch and learn, but
they are just so busy they aren't interested!
Any comments welcome - and if you want to talk to me directly you can

THANKS AGAIN!

See my post on the Pandora. This looks like what you need. Simple, no
overflow and only 4 pipes require connecting. Less work replacing with this
than with a new unvented cylinder.
