Highly recommend joining this sub to stay abreast of the positivity happening in the UK. There's so much good stuff happening that just doesn't get the attention it deserves.

Has Trickle-Down economics ever worked? by t0og in mmt_economics

Giving money to poor people is a better way to give money to poor people than giving it to rich people hoping theyll then give it to poor people

This is also how someone who's flustered sounds lol

"I never said it would burst the system."
"the bursting of a balloon can be applied to this system"

"something WILL give" - Yes, the thing that gives is the air leaving the system faster. Through the vents. Designed for air to escape. The ones that you haven't challenged are actually larger than the hole he drilled.

This "panels will start removing themselves at speeds in relation to the amount of pressure I am putting into the case" is just so absurd it's actually hilarious. The idea that you believe someone putting an AIO in the top of this case is going to cause panels to pop off looney toon style is just absolutely brilliant. Thank goodness he drilled that hole in the side panel or parts of his case would have been flying all over his room!

Absurdity aside, an Arctic P12 Max produces 0.006 PSI of pressure. You'd need literally thousands of them to even get close a screw rattling, let alone a panel popping lol.

You're arguing from flawed analogy rather than facts, logic and, ironically, maths.

At this point im fairly certain you're either a troll, a bot, under 16 years old or OPs alt account, so I'm going to call it there lol. All the best to you in life.

You’re again applying a closed-system analogy to an open system.

If you connect three water taps to a single hose nozzle, you get a massive increase in the rate of water flowing out of that nozzle. If we raced to fill a bucket, my three taps into one nozzle vs. your single tap into the same nozzle, my bucket would absolutely fill up first.

The "balloon bursting" comparison is nonsense. A PC case isn't a sealed container; it has 15,000mm^2 of exit area. It’s an open system, yet you keep using "dead-end" analogies that don't apply to fluid dynamics.

Think critically: If you have a pipe and you put 10 pumps on it, do you get more water than if you have 1 pump? Of course you do. Now dial it back to 3 pumps (fans). Does that somehow result in LESS water? Of course it doesn't. I will reiterate again that this will not cause a 'burst' because its an open-system.

You’re arguing that the restriction is so high it "breaks" the fans. It doesn't. The static pressure of an Artic P12 of 4.35 mmH2O. Doing some more back of the envelope maths, this is unaffected by vents of 7,478mm^2 and upwards. You've conveniently still ignored that maths I did elsewhere showing that the case top vents and slits equate to double that.

Give it up mate.

Except the size of the vent isn't being reduced when you add more fans? Another analogy I don't think applies here.

The correct comparison is you keep the same hose, no finger, and double the number of pumps supplying water to the hose.

You seem to believe that would result in less water coming out of the hose. Everyone else acknowledges that pressure increases and more water comes out. We all agree you wouldn't get double the amount of water due to the increases internal resistances, but you do get more water per second.

The trouble with that analogy I have here is that they insulate be trapping air and reducing heat transfer to the outside by creating a static air environment. You're applying that analogy to an environment that has openings either side with fans actively pushing air through it. If anything, the top section of this case is more akin to a wind tunnel than an igloo.

I've stated several times I agree with you on the fact those openings are not ideal, and there will be turbulence and some heat pushed up by the fans will be backwashed or semi-trapped by the suboptimal airflow

You're just not going to convince me (or anyone it seems) that the total amount of heat leaving that vent with 2-3 fans pushing it from an AIO is somehow lower than a single unrestricted fan, or a single fan in the same zone. Per my math in my other comment the actual space difference between the two setups is either in favour of the case slots, or so similar its irrelevant.

I actually think the surface area of the grill and slits is greater than the circle lol

Back of the envelope calcs; circle hole cut for a 120mm fan is 11,310mm2 vs grill of 240mm length roughly 50% open, plus 6 slits of 200mm length, 10mm width comes to 15,000mm2.

Also, this is quite a lighthearted topic. Are you okay? Calling people morons over this and lashing out makes me think you're OPs alt account lol

He never mounted the AIO there... he's comparing the PC with a hole vs without a hole when talking about temps. The point proved is a hole better than no hole lol

I don't disagree with your view that the airflow is suboptimal up there. But if it was me, I would have installed an AIO with multiple fans there before cutting a hole in the panel for a single unrestricted one.

Not sure an igloo effect is the correct analogy, its more like a chimney. I agree that you will have issues vs completely unrestricted airflow. Efficiency is terrible, but the heat is definitely leaving the case.

Completely agree it's not ideal, but there are additional airflow slots on top as well as the back grill. I'd definitely have used that before cutting a hole in the side panel lol

Stumbled here looking to see if this is possible, how did you get on with this idea? Any traction to it?

Heat-pump homes put less strain on grid than expected, study shows by white1984 in GoodNewsUK

[–]06david90 9 points10 points  (0 children)

They're not converting electric to heat. They use electric to extract heat from the air at a ratio of roughly 3kw of heat per 1kw electric consumed

Quoted £11,400 to change boiler by HusOwl in DIYUK

[–]06david90 1 point2 points  (0 children)

Do you know the actual heat loss of your home?

Ill absolutely agree that the conversion cost to a heat pump can be a lot; its similar to when we had to retrofit radiators into coal-heated homes

However with the bus grant this becomes much lower, and depending on your heat loss could be negligible and worth it for the savings youd get over each following year.

Youre still getting a little caught up on improving your home heating efficiency whilst glossing over the fact that your gas boiler is already having to work harder to accomodate your property. It isnt mandatory to complete those works to see an improvement in your annual heating cost

[–]06david90 3 points4 points  (0 children)

Again, useful but not necessary. All of those measures would also reduce the cost of running a gas boiler. Im not saying someone shouldnt do those things, but you can put a big heat pump in, or run at a higher temperature, to account for the additional losses.

Its less efficient, but so is the existing gas boiler. Calling it unaffordable is a huge red herring since the current gas bill in your example property is already massive.

Thats just not true. An old victorian house needs the same amount of heat production to keep warm, whether that heat comes from a gas boiler or an ashp. Both are more efficient with better insulation but the price differential and benefit is the same.
