End of Run Cold Room

PTN

What are some thoughts about keeping a room warm at the end of a hydronic baseboard heating loop (single loop system). The 1967 raised ranch house is heated with a natural gas furnace and has two zones (upstairs and downstairs). The furnace is downstairs against the south wall behind slatted sliding doors in a finished basement which is kept around 70.

The upstairs room in the northwest corner is always too cold when the rest of the upstairs is set at 70. The unheated garage (west wall has the garage door) is directly below this room which doesn't help.

The T-Stat is located on an interior wall of the dining room which is on the southeast side of the house.

Would moving the stat to the hallway (more centered) help balance, or would it just make the south end too hot?

Seems that being on the north facing side with an unheated garage below and at the end of the heating loop are too many things to easily overcome.

Any suggestions would be apreciated. Thanks

Base board

How long is the run of fin tube in the upstairs zone. Maybe two zones for the up stairs is needed. Many possibilties out there but need more info on your set up.How much fin tube is in the room and has this problem be an ongoing thing.

Closing or part closing some/all the louver on the baseboard(s) at the *beginning* of the loop (in the warmest rooms) would cause these room(s) to be cooler while the room(s) at the end will be warmer. Alternately, covering some of the fins at the beginning/in warmer rooms with aluminum foil would also achieve the same result.

Basically you get a little less heat delivered to the hotter room(s), while the same, or a little more even, is delivered to the cooler rooms.

Moving the thermostat probably won't help, just cause a different room to be at setpoint temperature, while th ethe early rooms will be warmer, and the later rooms cooler.

A potentially much more complicated solution may be to split the loop in the middle, adding a new line to feed it hot water there, and let it return from both ends. Yet another solution would be to create two separate zones from the one and add a second thermostat.

garage insulation?

how well is the garage ceiling insulated?

you could reverse the flow in that loop.
