yeah you can do that. I am not sure myself how to do it but the individual who answered above me seems to know what he is conversation about. I enjoy seen it within several houses.

I think rather more information would be needed to answer your question. Is it forced hot hose down from a boiler? Is it electric? Why do you need a thermostat if there's already a control on the baseboard? Do you tight-fisted to install a temperature measuring device to tell how hot the dampen is in the pipe?

Additional details:

The solitary way I can consider to do it is with a column voltage thermostat. Either you can run a cable from the heater itself or from the underground room (if on the first floor) or attic (if on the top floor) to put a thermostat, in series, where on earth you want it. This can be rather involved if it necessitate snaking a cable through a wall, but if its run on the surface (such as in cable mold or a baseboard cover) it could be fairly straightforward I'm not sure on internet sources, but I would be in motion directly to the electrical code or an electrical handbook to find out the code requirements within your area (most predictable NEC).

That being said, you should probably high an electrician if you have any doubts.

Answers:    bring a thermostat that uses line voltage and basically wire it into the fundamental hot wire going within. Yes it is safe and allowed. The wiring may requirement to meet local codes and they oscillate. Call your local building dept.
