Re: PTAC Air conditioner Blower fan hitting cover
not from whoever the manufacturer is but there is likely a replacement motor that will fit. A motor shop could change the bearings too but that would probably cost what the motor cost.
Look for up down play, my bet is that the shaft is tilted either down or up (depending on if the condenser fan is on the same motor or if it has a separate motor).
Re: PTAC Air conditioner Blower fan hitting cover
Put two or three screws into the cover near the center, grab them with vice-grips or something, then give 'em a yank to put a little offset in the metal. Then take the screws out.
Re: PTAC Air conditioner Blower fan hitting cover
i mean 40 year old bearings that have never been oiled seems like a very likely culprit.
Re: PTAC Air conditioner Blower fan hitting cover
check the play on the bearings for the blower. might be easier to get a motor than a new unit.

"If I decide to go hydronic"??? I forget. Is this steam at the moment? Because, if it is, PEX of any flavour is out of the question.
Re: PTAC Air conditioner Blower fan hitting cover
Not a bad temporary fix — also known as a kludge — but it would be wise to find out what has failed or bent or rusted away or otherwise changed from the original intention — since it didn't do that when it was new — and fix that correctly. Might also be a worn or broken mount for the fan or the motor — or both — or less likely sufficiently worn bearings to allow the fan to move…

That full quote is "The customer is always right in matters of taste" If the customer were "always right" about everything then well everything would be free! 😁 Basically if the customer orders the steak well done it's not our position to correct them. If the customer tells me that our steak comes from a pig and not a cow I would correct them (carefully and only once)
Re: Any ideas about this valve?
Hi, If you're getting more photos, maybe they can find some maker's mark on it. That would help us narrow things down. Aside from the leak, are there any other problems mentioned? 🙏

Re: Spanish power grid
You guys know more about power distribution than I do. I am just a dumb electrician.
I thought the reason George Westinghouse (AC Power) won out over Edison (DC Power) was because DC suffered more line loss and it couldn't transmit long distances as easily as AC.
Am I wrong or did I skip school that day?
Re: Spanish power grid
@JDHW "I wonder why the industrial revolution really got going when steam power came along and we no longer had to rely on windmills and waterwheels? "
Easy. For the first time we had dispatchable power. Worried about "net zero"? Install a bunch of small fission plants and call it a day. 👍
Trying to use non dispatchable, variable output sources is creating problems for which we already have solutions.
