Help needed to identify what this unit is and it’s purpose Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

I have a project in a home with an old gravity central heating setup.
I found this unit behind a panel in the dining room and I have no idea what it is or it’s purpose. It is mounted on an external wall but there is no outlet or vent on the outside.
Any ideas?

Hi foolishhart
When you lift the lid and look inside what do you see?

Looks like a radiator?
If so, can only assume that it was no longer required at some point and boxed in rather than removed?
