splitting a baseboard zone?

[KiltLifter]

I,ve searches all the keywords I can think of, and havent found a topic like this:

I have baseboard heat in 3 zones in my house. At the far end from the boiler is the master bedroom zone which rarely comes on because the main zone keeps it pretty warm.

What I want to do is split the Master Bed zone into 2 zones - one for the attached garage and one for thr MB.

Has anyone done this?

Shouldn't be much more than a matter of plumbing it with a supply and return and another valve.
How big is the actual garage?

I added 2 zones to my boiler with only one zone pump and 2 zone control valves they heat my garage and an extra room above the garage they are ~40ft from the boiler and I only had room for one more pump in my control so there's 2 thermostats that trigger the appropriate zone valve and the single zone pump I don't remember exactly how it was wired my electrician brother took care of that part but I know it had him scratching his head

Low voltage wiring always gives electritions ahead ache.

The garage is 20x20, I just need to keep it above 40F, but I dont want to or have room for a new zone, I would like to split an existing zone if that's possible. The bedroom zone I'd like to split is 50-60 feet from the boiler.

You can add to and split an exsisting zone "IF" the pipe/tubing has enough capacity. Need to know flow of pump, line size, and btu load. You can only have so much flow (gpm) from a certain size line.

The other question is how is the master bedroom manifolded or zoned now?

Also you have baseboard, what temp is it running at? Most of the time 140 plus. What is the exit temp? I floor heat needs lower than 120 so you may need a tempering valve. Or it may work fine in series with the bedroom(after) but won't have stable control.

You'll need to do some calculations to see if it can be made to work, but off the top of my head, I wonder if you could isolate each baseboard with monoflo tees and thermostatic valves to get a pseudo-zone effect on a single loop.

I did something like that in my living room, which was always too cold, because it really doesn't have enough usable perimeter for sufficient length of baseboard (with a large fireplace and doors in the way).

My solution was to replace the baseboard with a large radiator. But to be able to maintain the floor's balance (since this has vastly different heating characteristics from baseboard), I cut it into the loop using a pair of mono-flo tees, and the radiator itself has a thermostatic mixing valve.
