Re: Proactive steam valve replacement

Packless valves were for vacuum systems.

We still need to check it. In the first two pics above, we can see a nozzle container sitting on top of the boiler. The end cap on it is blue- which is the color Delavan used for solid nozzles. Hollow nozzle containers have red end caps.

Re: Oil boiler and outdoor Wood Boiler

Don't worry about the flow inside that HX, it will handle all that you have to give through the pex from the boiler. Very little pressure drop in a HX of that size, regardless of the connection size. It's all about the square footage of the HX not the physical size.

Typically the HX has some flow rate and pressure drop info on the label or any documentation provided.

Usually you select a HX with the design software, free online. You enter flow rates and temperatures, it spits out the choices. A couple examples. The 5X20" in this example moves 73,000 btu/hr

Re: A Question About Monoflow & Venturi Tees- Scoop vs. Orifice

The light fixture you built, Hot-Rod, is cool looking. Very creative.

"Diverter Tee" sounds good to me
I suppose the word Monoflo(w) is like saying Kleenex. A trade name that became generic.
The Red Ring's I've used had the cone. The one's I've seen marked Monoflo have the ramp. Who knows if that's universal.

You mentioned nickels in tees. On jobs, I've encountered some 3/4 x 3/4 x 1/2 copper tees that had 1/2 x 3/8 copper reducing couplings tack-brazed inside. Since they were in various facilities, I wonder if they were factory made somewhere.

Re: Oil boiler and outdoor Wood Boiler

looks like you have a number of pipe size reductions? On the back of the boiler, then at the HX also. It all comes down to how many gpm you are trying to move through those circuits. The underground piping size and length is where the bottleneck tends to be on those OWF installs.

Also, you need a circulator after a 3 way mix valve. Looks like you have a pump pushing down and into the 3 way.

Re: Bypass boiler tankless hot water coil while still running the boiler to heat the home?

Just to add — leaving the tankless coil empty isn't going to hurt anything.

Re: Radiator to Valve Question

I thought I'd follow up, and thank you all for your suggestions and comments. After long thought, I decided not to try unbolting everything, nor attempting to cut and re-thread the pipe (making it lower to the floor).

While looking at the local hardware store, I bought four 1" end caps with a bunch of washers. They were flat on the bottom, and the washers could be used to stabilize, level from to back, and create slope towards the valve. I was pretty happy with the end result, and better yet - so was my bride!!

That's how I do it. It's not a code that must be adhered to.
Some might want to purge.
As long as the heat works, pressure maintains, and the burner circuit opens on limit, then it's all good.
