Add a Zone or Change Thermostat Location? (floor, heating, bathroom)

[clutchrider]

I realize there is a greater expense in adding a zone for heating. But the issue is that our heat is baseboard radiant hot water and our thermostat for the upstairs is at the top of the stairs in the hallway and the upstairs is open to the first floor so the heat from downstairs comes up a bit. This causes our master bedroom and bathroom to not warm up enough when I set the temp.

I could turn up the thermostat but is prefer not to waste unnecessary heat. Any thoughts or ideas?

When I lived in a two story house (with hot water radiant heat on the first floor with baseboards upstairs), the upstairs thermostat had to be kept a few degrees higher or the upstairs bedrooms would be cold.

It was a rental, so I wasn't free to make any changes. But, in your case relocating the thermostat would be easier/cheaper than doing anything with the zones. However, you do have another option - a thermostat with a remote temperature sensor. The sensor could be located in your master bedroom area and would resolve your issue.

I had a house once where the thermostat was directly across from the front door.
I moved it out of the draft within a month.

I believe moving the thermostat would give you the results your looking for.
