Re: Any new feelings about Stay Brite 8 soldering vs brazing?
I recently had to move a lineset in our shop and I bought some Staybrite 8 as well as the Stayclean flux, both paste and liquid. After doing a few tests I decided to braze everything using Staysilv 15. The reason was I didn't feel like cleaning every joint and dealing with flux. So, I brazed all of the joints because it was quicker and easier. Silphos isn't anywhere near as picky with your pipe and fittings being spotless as soft soldering.
My current opinion on it is the connection strength etc isn't an issue but I've never brazed / soldered anything near a compressor, so I can't comment on that. It's having to clean everything (just like soft soldering plumbing) without getting abrasives in your tubing, and then try to be extremely clean with flux. So, if it's something you can braze without concerns, and you've already got your nitrogen bottle out of the truck and connected I'd stick with silphos. If it's in a tight area, or something that you can't really get too hot, I'd take the time and use Staybrite.
With Staybrite you don't need to purge with nitrogen, which can make some jobs a lot easier.
I think both have their uses and you just need to decide which is the easier / better solution for each job. Like I said, I haven't put a new compressor in, and I have heard guys say you really need to braze those connections, so for now I don't have an opinion on that.

Re: Forced hot water heat options in small pantry?
If you use a toekick you must have an access panel. If you have sheetrock below how would you install it without an access panel?
For the amount of heat you need its not worth the stress you don't need any heat
Re: COP & sizing question
To answer the implied question in @oreo123 's post… there are really three questions. First, will going to a higher BTUh output heat pump help keep your clients from shivering on cold winter nights? Yes, but only if it is a heat pump designed for cold temperatures. Some are, some aren't. Second, the some of the ones that aren't can be saved by adding electric resistance heat.
Third, will the client save money in relation to what gas or oil would have cost? No. Emphatically no. The electric rates vs. oil or natural gas prices in New England (not just MA') are high enough that oil or gas fired heat is going to be cheaper, maybe a lot cheaper. The Mitsubishi @DCContrarian mentioned is a good cold climate heat pump, and should only cost about twice as much to run as a modern oil or gas boiler or furnace.
Re: Forced hot water heat options in small pantry?
you have maybe an 800 btu load, if it received no other heat, which it does
Put a 150W incandescent light 💡 in there

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.
