Good day,
I am building a new home with brick walls and concrete roof. I have a wood stove on one side of the home and would like to get it to heat my master bedroom on the second story at the least. I doubt that heat going up the stairs would work.

What would be the best simplest system for this?
I considered a thermosiphon radiant floor heating system with a few coils around the top of the stove, going through the bricks and rotating back down to create a circuit. Is a tank necessary at the end of the line to let it cool down and recirculate down?
I guess a vent would also work although there would be more noise transfer from downstairs to upstairs. Is a fan necessary?

Thanks for your creativity,
Fernando

Here are the plans of the area

It’s going to be a challenge to heat the master. Just put a mini split up there.
I think another challenge is your elevation. Are there a lot of home that use wood stoves? if so what is a popular brand? The common charts here show about 40% over minimum height to compensate for your elevation. Adding any elbows increases it further increase the required height. If the home is air tight adding a freak air intake to the stove is a good idea.

With new construction insulation is your friend. Your hydronic idea is complicated. I wouldn’t bother.

I think the only way to get decent heat in the master bedroom would be a hole in the floor with a fan pumping cold air from the floor down to the stove level. It'll then be replaced by warmer air coming up the stairs. (if you do so, remember that you are making a hole in a firebarrier, so consider a firedamper or talk to your local authority of jurisdiction regarding building safety).

Otherwise, I think the stove is not going to have a significant effect.
 
I'm also a little late to the party on this thread, but you can do some tricks with insulation to get more of the upstairs bedroom heated by the downstairs stove - 1) superinsulate the attic/roof above that bedroom, 2) superinsulate the walls of that bedroom, and 3) don't insulate the floor (let heat rise through it from downstairs). I just look at current forecasted temperatures for the next 10-day period in Quito, and it doesn't look like it gets too cold there during the winter, so this may work for you.

Superinsulation is not just about getting more insulation in ceilings and walls, but also making sure that you have no thermal bridging (or minimizing that) and that your air sealing of the space is exceptional. Traditional insulation contractors, sadly, will get none of those details right so you will have to personally perform that work (my opinion based on my experience in the US).
