  • Central heating: is there any good way?

    Jump

  • 'Big' is relative. It's a house in between two left and one right in a block of four. It's big enough for two people, but it's not huge.

    I'm not sure I understand the function of the buffer mentioned. Is it a heated buffer that can pump around hot water without having to expend gas to heat? How does that differ from the expansion vat I have? Is that just to soak up excess pressure?

    Sorry about all the questions, I'm just not sure about all of this stuff.

  • English is not my first language and although I can kinda get my point across, technical jargon is a bit of a blind spot. So just to clarify: I have a little vat of say 10 liters connected to the heating pipes. It's next to the boiler. It contains a rubber membrane in the middle to expand if pressure builds. Is this the type of buffer you're referring to?

  • There is only one TRV in the living room because the other valves are not thermostatic. I would need to replace those to achieve what you describe. But then I think that's not the way to go because it could damage the pump from what I hear.

    The boiler is a Remeha Tzerra Ace which supports Opentherm with modulation. It's also wired on the opentherm contacts and the T6 supports it.

  • Ah no there is one of those expansion vats in between. It's not huge but it doesn't need to be.

  • The issue I'm trying to solve is to heat a room upstairs whilst not having the boiler in a constant 'on' state (the main thermostat is modulating and uses OpenTherm to communicate but that's beside the point).

    A use case: say I'm going to work in my room upstairs. It's currently 18°C. The living room, where my main thermostat is, is 18°C. I have my coffee in the living room, causing my automation to recognize I'm in the living room.

    I move up to my room and set my comfort temp to 20°C. The thermostat in the living room adapts to that. So does the TRV in my office. Since the setpoint of the main is higher than the measured room temp, it sends a heating request to the boiler. One of the radiators in the living room is closed, since the presence detector don't show occupation in the living room.

    In this case, my office might not make it to 20°C before the living room does. The pump stops and no newly hot water gets sent to my office even though the valve is open.

    Bottom line: with the current blueprint I mentioned, everything works moderately well. What I want to avoid is to have the boiler heating water if the only occupied room is already at its setpoint. What I want to achieve is more control over when the boiler should heat water (and also pump it around) so that I don't have to heat the living room when heating, say, the bedroom.

    Oh and as far as the time between presence sensing and heating goes: I'm fine being a little chilly for ten minutes. Like I said, I keep every room at a minimum of 18°C to make sure it never takes too long to heat if I want it.

  • I considered this when getting my TRVs but I prefer it to be Zigbee. Also I'm not planning to substitute all my current TRVs for different ones, that'll be a costly operation. I think if I was looking for a closed (ie one manufacturer) system I might lean towards Tado or maybe PlugWise.

    Thanks for the suggestion!

  • How to work around RAM prices?

    Jump

  • Is it? Team Group predicts this is just the start and it's going to get much worse.

    Behind the scenes deals are being made between Samsung/SK Hynix and all the AI companies and the focus will not be to produce consumer DRAM

  • How does the RSS feed thing work?

    Jump

  • Any site that generates content can choose to create an RSS feed. Essentially it's a link to which the site can push new stories.

    You need an RSS client. Good news! There are a lot of free ones (and open source, too!).

    The pro's of RSS:

    • all your different go-to news outlets in one place
    • no ad-ridden webpages
    • no dealing with interfaces of said news outlets
    • your pick ff categories, for instance if you're not interested in celebrity gossip, you just turn that off

    The cons:

    • you'll need to go collect RSS links from your favorite sites
    • one of your sites might no longer use RSS because they don't get ad revenue for it
    • RSS readers are often not pretty
    • you might get weirdly formatted text pages sometimes

    What's the psychology of people who slam their front doors in apartments everytime they go in or out?

    Jump

  • It's wholly possible these people are not bothered by loud noises. I have neighbors and especially their kids seem to have no clue what an inside voice is, how far bass travels or how to walk down stairs.

    They shout, they blast music, they fall down stairs.

    If I did that as a kid, my dad would tell me to cut it out. And I think that's the key difference. You're either raised to be considerate of others, or you're not. And if you're the considerate type, most likely you'll go out of your way because you don't want them to be bothered by you while they might not even register if you happen to fall down the stairs or fire a cannon indoors.

    I used to be really careful with watching tv at certain hours, or announcing to my neighbors of I was going to have people over. It took me a while but I now don't even really care if they hear me anymore. Because even if they do, it's unlikely they'll be bothered as much as I am when their preteen kids shout that they don't want to go to bed at 10:30 PM when I'm trying to sleep.

  • How do I check my router for malware?

    Jump

  • I'm not familiar with how malware like that masks but you can pretty much find any traffic with a tool like WireShark. It's just a matter of finding out how processes recreate themselves once killed.

    If something lives in the storage of your router, specifically, I'd see about formatting the storage and flashing new firmware. As you stated, that may not solve anything.

    Regardless of how they enter and what is installed where, once it's inside your home network it can pretty much access anything. If you wanna be fully secure you'd need a firewall and just block any traffic you don't specifically whitelist. As you can imagine, this is cumbersome.

    Are you worried that something has infected your network devices? Do you have any reason to suspect something? In some countries, ISPs do some passive monitoring on what goes in and out of your home and if they see anything untoward they'll disable that bridge device and notify you.

  • It shouldn't really be the purpose of Big Tech either. It's fairly difficult to define freedom if it takes the form of exploitation of human behavior for profit. Social media is little more than an addictive ad delivery system.

  • Buy Nothing Day

    Jump

  • I'm torn though. At some point I am going to buy stuff I want or need. If I were to buy them at full price rather than on Black Friday, I am essentially being more of a consumer per money unit.

    So yes, don't look at Black Friday deals and decide you need stuff you see on sale. First decide whether you need something, then go see if you can find a good deal and maybe buy it.

    I think the idea is not to not buy anything for a day, it's more about redefining what we need and applying a little impulse control. If Black Friday is profitable, we need to make them keep the prices that way year round rather than applying huge markups to maximize profits.

  • In advertising as well. I noticed quite an uptick in the 'annoyance' factor of tv and radio ads somewhere between 2005 and 2010. People were more likely to discuss bad ads, or ads with a quirk of some kind. Hate is an easier strong emotion to coerce with an ad so they fully went with it and somehow the negative attention equalled more sales.

    It's hard to imagine some business exec coming up with this research, it's more likely a team of psychology majors who would rather earn more money than actually help people.
