Re: Tankless coil feeding storage tank?
This...
is why only 3 ports on the Aquabooster. Better than a tankless by itself. Worse than an indirect with cold start, or another more efficient means of DHW.

Re: Type K copper pipe
Hi, Maybe a dumb question, but do you have a water quality report for your water? I ask because if the water is agressive enough to damage solder, I'd be concerned about what it will do to copper. Some sort of plastic piping might last longer, even if it means putting it in conduit to prevent damage and to make it far easier to replace if ever needed.
Yours, Larry
Re: New thermostatic radiator valve on old radiator fitting?
Item 3 above. Almost no chance at all, though it has been known to happen. People win the lottery now and then, too.
Re: Type K copper pipe
Code does not allow you to bury a soldered line regardless, so it would need to be brazed.
That said, I'd use either hammer flares or pack joints or similar. That's what's typically done on water service lines.

I even used one in my basement rather than soldering it because it seemed like a really good connection and could easily be worked on. It's a compression joint with a very thick heavy rubber gasket and a metal clamp that secures the pipe. I believe they're called pack joints because they used to use lead packing.
These aren't cheap cheesy compression fittings, they're literally what water companies use for this work.

Re: Outdoor reset
I just called vesta tech support and the guy told me they have them in stock and can ship them out overnight shipping so you might try calling them again! They also told me you could use a 3rd party one for what its worth i didnt ask for that part number i just told them I was trying to help someone locate a sensor for a VRC combi

Re: I'm getting solar panels. I'll let you know how it goes in this discussion thread.
Update: The fire inspection passed (that one was basically to verify necessary clear areas on the roof). Then the solar contractor applied for the final inspection and Net Meter from PSE&G (our power company).
Today I got notification that PSE&G processed that application and ordered the net meter. They will do a final inspection and swap the meter within 25 days if everything looks good.

Re: Adding a radiant manifold to existing single zone loop
Not a condensing boiler.
Look at the vent pipe. A condensing boiler would use a plastic vent pipe because all the flue gas condensation would rot the galvanized vent connector away in a year. According to the manual this is a better way to do the near boiler piping if you want less problems with air in the system.
Assuming that you are connecting to standard Baseboard heating units with 3/4" copper tube. The circulator on the return indicates the installer didn't read the manual and followed the directions his father who taught him to do it that way.
Re: Steam device to be identified
@mattmia2 " What is this tube, where does it go? "
This tube ? Maybe the radiator supply.
Multiple pressure controls the lower two looks like Vaporstat size diaphragm diameter.

Re: Steam device to be identified
@Steamhead It appears to vent the air out, it has to go through a bit of water at least the height of the boiler water, Figure 205. It makes it harder for the air to get back in resulting in a vacuum for faster steam propagation with the next cycle.
