can't find my feed and expansion tank

[timbristlin]

Morning all. Looking to replace a rad and trv in my house ( 60's bungalow). I have an aga for the heating linked to an immersion. However I just can't find the expansion and feed tank anywhere. Cold storage tank for immersion in loft but for the life of me I can't see the f and e.

As stated in previous post you probably have a prismatic cylinder.
PRIMATIC Auto correct can't spell

Wasnt taking a pop in the other post, just didnt realise they dont cover different types of system.

Make sure its not the heat leak you are sticking the trv on.

As above, solid fuel needs a heat sink. Leave one rad open at all times ,preferably a big one.
