Hi. I recently moved to a new house and with the heating season started we are experiencing too much heat in one bedroom to the point that occupant cannot sleep there even with fully closed enclosures. I made a full baseboard plan (attached), all pipes are in the basement ceiling and coming up through the floor to each room right into the baseboard and then leaving to the basement the same way.

Bedroom #2 is the troubled room. My question is, if i can convert that one room to monoflo-like system (option #1, with TRV valve after the supply split and diverter tee at the return split).

But i also saw that there is another work-around exists (option #2, with adding 1 size smaller bypass around the baseboard), both options are described in another attached drawing (sorry for the messy sketch).

I'm reading conflicting information here and there, some sources say that this would add too much resistance, mess up the flow and that eventually the circulator pump may overheat and die.

The goal is not only make the room colder, but give some sort of basic control of how much heat the room can receive with outside temp changing throughout the season, without spending ridiculous $$$ (i.e. making this room a separate loop with it's own thermostat & pump).

Kindly please help!
