Re: Identify this radiator heating element and baseboard convector enclosure
@ariccio, it seems like your recent discussions are varied enough to remain separate, but please try to streamline them moving forward if your questions are similar. Thanks!
Re: Any downside to high pitch?
Vertical steam mains and risers certainly have a lot of pitch.
Re: Made In the USA vs. ?
I think there's survivorship bias going on in regards to USA and Western European made goods. Globalization has made it difficult to compete on the lowest priced goods manufactured in countries with higher wages. Because of that, most of the companies that have survived making goods here have had to focus on quality. This, with good reason, has made people notice that on average USA made goods are of better quality simply because there aren't many companies left competing at the low end.
It's not that China or wherever can't make quality goods, it's just easier to find quality when buying US made because the third world has the bottom end of the market saturated with lower quality cheap goods.
It's getting more complicated by the fact that the supply chain is global as well, making it even hard to tell where something is truly made. Also the difference in price seems to be getting bigger to the point that for most things, I'd rather buy tools made in Taiwan and get a tool maybe 80-90% as good as the US made if it's going to be 1/3 of the price.

Re: Made In the USA vs. ?
The above comments are all valid.
The experience with Chinese fittings is expected. They are a low technology product a and the purchaser ("manufacturer in the US") does not have any quality control over the production in China. The Chinese produce an inferior product based upon thread OD, and pitch diameter and the product sells in great quantities in the USA. So, why would anybody try to improve the quality of this product?
Now, take the example of Apple who build cellphones in China. I am quite sure they have an extensive staff ON-SITE in China that inspects a certain percentage of all products and rejects the entire batch if one of them is flawed.
This cannot be done with plumbing fitting due to the low value.
So, it always depends on whether the US manufacturer can expend the funds to ENSURE that the product meets the specification.

Re: Lennox Heat Pump "Mystery" issue.
Do the calls go away at the heat pump (i.e. no 24VAC between Y and C & O and C)? That would indict the thermostat.
If the heat strips are on, did the HP call for them (energize W/W1/whatever)? Maybe there's a low ambient lockout thermostat that's shutting down the HP & passing the heating calls back to the heat strips; or the defrost board is getting stuck.
Lots of different things could be going on, just going to have to catch it while it's happening.

Re: Help troubleshoot banging pipes
Without opening something up to evaluate the hidden pipe pitch about the only thing you can do is try raising the entire radiator up a bit maintaining it's correct pitch. Use a 2x4 to slowly and carefully cantilever the radiator up. If it won't budge don't force it. Slide maybe a 1/2"spacer under each leg if you can. Sometimes this will fix the pitch of the pipe below the riser to the radiator.
Re: Simple Steam Heat Thermostat Recommendations
Try a little less than max first and see how it works.
Re: Lochinvar NKC150N - DHW High Temp Issue
Your blue mark looks to be flue sensors to me, similar sounding words but different functions. Flow sensor will sense flow on the water side, flue sensor will measure temperature of the flue gas

Re: Navien combi-boiler motorized threeway valve replacement
You paid for a lot more than just a valve. You paid for his experience to be able to diagnose the problem and source the correct part. More than likely they bought the correct part form a source a lot more reliable than Amazon and certainly paid a higher price for the part. Be thankful that they fixed it on the first try.
