Re: Need 80’ of line set — where to buy? Or how to extend? No name lines ok?
Nothing wrong with brazing its been done for years. You don't have to buy a "line set".
Just go to an AC & Refrigeration supply house and but AC & R tubing. It comes in 50 foot coils braze it and your done. By insulation and slide it on. No big deal.
The first MiniSplits that came out were all brazed.
If most techs new how to braze and use nitrogen or how to flare thing would be ok. Or use the press fittings that everyone but me loves.

Mitisubishi frowns upon brazing there mini line sets.
flair them.

Re: 3 Q's: PexA - Heat removal from attached MA and Pex2Copper Press fittings | Swing arm still needed?
you can whittle the pex away slowly until you get almost to the brass to get it off the fitting. be careful because there is a ridge in the fitting that sort of sticks out. I wouldn't be super worried about how hot the other end of the fitting gets if you concentrate on the tubing, since the tubing is nonconductive the heat won't transfer much to the fitting if you concentrate on the tubing and just get it hot enough to slip off.
btw, painting the tubing would have shielded it from uv.

Re: Converting to a hot water heater
The Buderus DHW tank is different from any Direct fire stand alone water tank. I have seen gas fired water heater with a 6 year warranty last 7 years before the tank starts to leak. just long enough for the warranty to be over. I have also owned that exact tank you have. It lasted 28 years in my own home. I don't remember dealing with the anode rod in the 28 years of ownership. Now everybody's water quality is different, so I can't predict what will happen with your Buderus tank. I just believe that you can do the Anode Rod Replacement and you should be fine.
Re: Leaking Radiator and Boiler Filling No Autofeeder hi
Wait! "the red circulator connects… directly to the top of my hot water heater…"
Is that water heated by hot water from the boiler? What is called an indirect? Those are notorious for leaking from the domestic hot water side to the heating side…
Re: Baseboard no heating
Did you do the install or a Pro ? Post pictures of the boiler and the surrounding system / piping. Boiler Make and Model. Any circulator and/or zone valves for the baseboards ?
Baseboard system pressure OK ?

Re: Weil McLain 1107-1 baseboard hot water wont shut off
could be a stuck end switch or zone valve too if it is using zone valves.

Re: How would you tackle these issues with my hydronic heating system? (1920s home)
Fellow homeowner with a gravity system here. Have you checked the radiators on the old gravity loops for balancing restriction disks in the radiator unions?

Re: Leaking Radiator and Boiler Filling No Autofeeder hi
If a main floor vent is leaking water, you know two things: that vent is all done and you need a new one. Second, the boiler is insanely overfilled. If that vertical copper line with a valve on it in the first picture is the only way to fill the boiler (no indirect, no DHW coil) it has to be leaking by. Easy to check. Drain the boiler down to halfway on the sight glass. Close that valve. I don't see a handy union on that line… pity. But anyway, if the water level in the glass rises… there's your problem.
If there is… new valve time. Use a ball valve.
