You must post before you leave

Be nice. Assume others have good intent (within reason).

Block or ignore posts, comments, and users that irritate you in some way rather than engaging. Report if they are actually breaking community rules.

Use content warnings and/or mark as NSFW when appropriate. Most posts with content warnings likely need to be marked NSFW.

Most 196 posts are memes, shitposts, cute images, or even just recent things that happened, etc. There is no real theme, but try to avoid posts that are very inflammatory, offensive, very low quality, or very "off topic".

Bigotry is not allowed, this includes (but is not limited to): Homophobia, Transphobia, Racism, Sexism, Abelism, Classism, or discrimination based on things like Ethnicity, Nationality, Language, or Religion.

Avoid shilling for corporations, posting advertisements, or promoting exploitation of workers.

Proselytization, support, or defense of authoritarianism is not welcome. This includes but is not limited to: imperialism, nationalism, genocide denial, ethnic or racial supremacy, fascism, Nazism, Marxism-Leninism, Maoism, etc.

Avoid AI generated content.

Avoid misinformation.

Avoid incomprehensible posts.

No threats or personal attacks.

Moderator Guidelines

Moderator Guidelines

  • Don’t be mean to users. Be gentle or neutral.
  • Most moderator actions which have a modlog message should include your username.
  • When in doubt about whether or not a user is problematic, send them a DM.
  • Don’t waste time debating/arguing with problematic users.
  • Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
  • Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
  • Ask the other mods for advice when things get complicated.
  • Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
  • Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
  • Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
  • Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
  • Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
  • First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
  • Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
  • No large decisions or actions without community input (polls or meta posts f.ex.).
  • Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
  • Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

Theoretically you could use a heat pump to heat water that would generate "waste cold", but heat pumps typically don't get nearly hot enough to heat water as much as a gas water heater does. I suppose one could be made but it would be very difficult, I think. It would need to use the ambient air in your house and suck enough heat out of it to heat your water, and if your house is about 72°F / 22°C and you want water at 130°F / 54°C (which is pretty typical) that seems like a challenge, especially since water is so much denser and has a higher heat capacity. I have a portable A/C with a heat pump and it starts to struggle to heat my apartment once it gets down to 45-50F outside and it struggles to cool once it gets above 95F.

Check if you can get some shade on your exterior unit. Also check that the area is well ventilated.

And as always, insulation is king.

I'm renting, I'm doing the best I can with what I've got. The entire unit is inside and I have a huge tube going to a panel in my window. It works surprisingly well.

[–] SapphironZA@sh.itjust.works 1 points 2 hours ago

Yeah, those units have their limits. Better than nothing though.

Its all just about the relative compression ratio of the refrigerant. They make heat pump based water heaters that have external units that operate identically to air conditioners running in a heating mode.

GE currently sells a heat pump water heater on the market, I'm not sure if it uses resistive heating to supplement the heat pump

Your AC may be undersized if it doesn't perform well in hot weather, also unfortunately many heat pumps aren't optimized for extreme cold weather performance. Some are, it's definitely not a failure of heat pumps in general, but you'll only find those as permanent install units and they're usually only sold up north.

Mine is general purpose, I suppose. I'm gauging its performance based on the temp of the air coming out of the unit, I think the room I'm using in is within range of it's cooling/heating capabilities. Didn't realize GE was making water heat pumps, nice.
