Re: Forced hot water heat options in small pantry?
Yeah my wife said the same thing (i.e. doesn't need heat). She thinks the dryer will make the room warm but I'm not so sure. Regardless, the room is the size of a walk in closet. We were planning on keeping the pocket door closed though in case the laundry area is cluttered. Maybe we should get a door with louvers? That would also allow makeup air from the rest of the house when the dryer is venting.
We could have electric radiant floor or wall heater just in case.
Re: Forced hot water heat options in small pantry?
It doesn't need any heat. No one is living in it or taking a shower in it. Waste of money to heat it. Leave the door open most of the time especially in cold weather.
You could use an electric cabinet heater. They are small and fit in one stud bay and have self contained thermostats and can run on 120 volt. They are semi recessed usually with about 1- 1 1/2 sticking out of the wall. The cost of doing anything with HW is more than its worth
Re: Help Sizing A Multi-Zone Mini Split System - Minimum Capacity?
the manufacturer specifies what size and how many indoor unit units per outdoor unit.
if you’re doing a whole house go with two or three complete systems. If or when something goes wrong you’re not dead in the water.
who’s going to install these?

Re: How many btu/hr from this cast iron radiator?
Looks like an American Rococo, and yes, it is steam-only. It cannot have been original to that system.
Please do not desecrate it by drilling and tapping for bleeders on each section. You can probably arrange some sort of trade with someone who has a hot-water Rococo. That one you have is 60 square feet.
Re: Boiler supply and return pipe size
The manufacturers installation manual will show piping options. They are all online these days.
To move 80 thousand BTU/hr, probably 1" is your best bet.

Re: Any new feelings about Stay Brite 8 soldering vs brazing?
Back in the day a lot of guys used Stay Brite on everything. I wouldn't use it on discharge lines though. And it for the most part held up very well.
I too used to Stay Brite filter driers and expansion valves…things that may need replacement, but I sometimes brazed them as well.
Everyone has their own opinion, I just trust brazing more. My opinion, and you can fill gaps easier.
The following is a list of pros and cons:
JW Harris says Stay Brite joints are stronger than brazing because the tubing is not annealed
No nitrogen purge needed with Stay Brite
Stay Brite may introduce flux
Some say codes require brazing due to the low temp (500deg) melting point of Stay Brite in a fire…phosgene gas an issue for firefighters.
Equipment does not come out of a factory with Stay Brite joints.
Some say Stay Brite will not take high pressures needed for 410A, 454B and R32
Don't shoot any arrows. I am just listing some items. Both have pros and cons.
Re: Capacitor Help Please!
those caps are potted, there is a printed circuit board embedded in that gray potting compound and are caps for a switching power supply, not an induction motor. that probably uses a vfd or variable voltage to run the fan motor. Those caps could be that supply or they could just be rfi suppression or power factor correction.

Re: “Height” of modern radiator valves vs old?
That works but I see nothing wrong with a couple of hardwood strips stained to match the floor
Re: Forced hot water heat options in small pantry?
Small electric heater or T-Stat controlling toe kick fan, let the HW flow
