There have been a number of posting recently about gravity HW systems which
I have read with interest, having put off the job of upgrading the current
layout year after year. After doing a good search on google I think I have
all the concepts, and think that the way to go is just to stick a valve on
the cylinder.

Can anyone help me out, and let me know if there is a
simpler/easier/better/more efficient etc etc option before I buy the bits.

I have stuck details on my system on a webpage, so you can see how it is all
plumbed together, any thoughts, comments, recommendations would be
gratefully recieved. I rather be 110% clear on what I am doing, and get it
right first time, than fiddle and have no heating at all!
