How to recognize circulating hot water system

jalecjalec Posts: 2Member
Hello -

My apartment has baseboard heating units in the bedroom and living room, with

2 separate thermostats.  Inside there appear to be one large and one smaller copper

tubes, with aluminum fins on the larger tube. I have been told that this is electric baseboard heating but it looks to me like it must be circulating hot water. How can I tell which it is?   Thanks in advance, my first post.
