Is my CH/HW fully pumped? Is it two-pipe?

You have a 2 pipe fully pumped system which in all honesty could do with upgrading the old girl is in her twilight years and not very fuel efficient. Regards kop

That's very sound advice, I think, which I will probably follow in the near future. However, I am confused by the images attached to your post. Are they relevant? Thank you.

Before and after pictures of a system the same as yours which i upgraded, if you should decide to replace your old boiler and cylinder this is what you should expect . Kop
