Just commented on your BLDC vid, but the fact you've been sticking with this educational work so often and so quality and so free to viewers is.. respect
Awesome..... I am a General Supervising Electrician, and I Love The Engineering Mindset !
Both copper and Kanthal wires generate heat, but Kanthal requires significantly less current to do so. Efficiency in electric heating involves converting the kinetic energy of electrons into thermal energy as effectively as possible. Achieving 100% efficiency would mean your electricity bill would be zero.
I was looking for a video explaining electric heating a few weeks ago, there aren't many explaining the principles behind the use cases for electric heating. Thank you for the breakdown and examples.
Thank you. I have always wondered how self-regulating heating cables work.
Great videos! Thank you for your wonderful work!
Thank you so much for this free information it’s so valuable
Great video as always!
Great video information ❤❤❤ thank you for Your TEAM
FOR sharing your knowledge 🇵🇭🫡
Amazing I am commenting without viewing the video amazing plz make video every day love from India and you are my electric teacher i learned all the things from you only
My range stove uses electric heating.
Question: How is one going to get wind farm spinning (@4:19) in a cold climate when the blades freeze during the cold?
We use NiChrome wire for cutting foam into shapes like airplane wings with specific airfoils.
Cool video! Looking forward to your next.
Again a fantastic video sir. Waiting for your next video
Fascinating
As you said, I have seen it everywhere, but surprisingly going outside of Norway I see both gas, wood fire and other types of heating used a lot more.
Just been a couple of weeks in Namibia and there solar and wood fire heating of hot water is much more common unless you are in the big cities.
Seen our new video on HOW SOLAR PANELS WORK in detail czcams.com/video/Yxt72aDjFgY/video.html
Always teaches us something different and new, lots of love and respect from Pakistan
We’re thinking of upgrading our local village hall from our old convectors to infrared. The companies selling this often contradict each other. Some insist that short wave IR should only be used outdoors and others claim it’s perfectly fine. I’m still researching this as our usage is intermittent and we need heat fairly quickly and IR seems the way to go as regards efficiency and comfort. I’m wondering whether medium wave will be optimal for our situation?
Hopefully you can make a topic about *CONTACTOR* component. I'm curious how it works.
I think it's just like the relay
Cool, having a comparison to natural gas and mega joules etc required would’ve been cool
Breifly covered 4:19 and 6:27
Cracking new video👍
A video on PTC heating elements, please.
3:17 Power is just voltage times current (P=UI), both of which are known. There is no need to re-calculate the voltage to get the power by using the (P = RI²) formula
Duderino, I think he is really aware of this. LoL
@@GooogleGoglee apparently not
I am currently using an portable electric baseboard heater for my dorm room. It is almost silent and can run constantly. I use it too keep my room a little warmer than the other room. My main heating has failed entirely in the past so the original purpose of this was to have it take over automatically if needed.
Username checks out
Provocative! I love it
please make a video on sensors
I'd like to request a video explaining portable generators for residential temporary back up power. Does neutral have potential to back feed utility power lines? Thanks
1:04 oh no， catch that magic smoke
One form of electric heat that I have seen in other videos, and I can image, not a very efficient or efficetive one "Radian Ceiling" electric heart. I've heard of in floor electric heat here in the US since the 90s. I think the radiant ceiling version wouldl be rather uneven and hard to regulate. First time comment. Very interesting videos!
Yes, I had this in a place I rented. Never seen it before or since, but, I'm glad though, because it was terrible. Heating the hottest part of a room definitely doesn't seem comfort focused.
Our 1985 house in Western North Carolina mountains is heated entirely by ceiling radiant heat (sandwiched between 2 layers if sheetrock). It works well but is about the least efficient way to heat. Looking to replace it with heatpump hot air w/AC (no AC currently) for better efficiency - also concerned with safety of existing wiring after 35 years.
At my place there are lots of broken ACs and there are no technicians. I want to be a technician, can I get knowledge from you?
I use electric heating every time I use a vape mod. 28 watts on a .47Ω stainless steel 316l coil gives me a nice mtl cloud.
my vape! i build tri core alien coils (ni80 or ni90) the battery sends power the wire heating up and causes the cotton laced thru the coil to vaporize the ejuice from the cotton.
How safe is it to install an electric heating system like the one shown in this video, for example under a living room floor with carpet? 😮 What precautions need to be taken?
❤ Thank you in advance.
don't it tip over and you're good
Material resistance with current or charge flow cause heat😊
The block heaters used on diesel engines keep diesel from "gelling."
Please explain working of MOSFET pls
See my new MOSFET explained video here➡️: czcams.com/video/AwRJsze_9m4/video.html
Biggest issue with electric UFH is the placement of furniture. OK in a bathroom where things don't move but in other rooms you can easily damage the UFH and furniture by creating hot spots.
Induction Cooking Cooker, Electric Kettle, Heater
I run across heat strips quite frequently. Mostly in heat pump AHU's and Fan Powered terminal boxes. Sometimes for dehumidification located in the ductwork. I also see it for heat trace on piping
Can you recycle the heat generated to generate electricity
👍
Completely off the topic of this video, could you do some videos on (NDT) non destructive testing (for dummies) ?
Make a video on how atomizer works
I work on a lot of VAV’s
Can anyone refer the type of cables that are used in those socks/gloves/clothing that are used to heat the clothing up?
tungsten have low resistivity so it can generate less heat so why it is used it has high melting point instead of it why we not use other materials ??
My home built in '69 has Ceiling radiant heating. Works good but not sure of the energy cost.
My apartments ceiling heat mostly just heats the floor for my upstairs neighbors, because America apparently just wasn't very smart before the 1970s 🥴
Can you make a video on wires
I am confused. I think I need clarification. In 2:34 You said High resistance generates more heat. This implies that high resistance, less current flow will generate more heat. Right? Then you said In 9:20, you talked about current flowing less leads to less heat being produced. I'm confused. Less current generates more or less heat? Please listen to what you said in 2:34 and 9:20
The first statement is wrong/misleading. High resistance only generates more heat *if the current is fixed* (P=I^2R), in a normal heater you have a fixed VOLTAGE (e.g 120 or 230 volts) and in this case you get more heat with LESS resistance (P=V^2/R)
LETS GO LIONS!!!!!!!!!
What about infrared radiation, during of heating devices?
I've made tea by using heater.. hehe
I noticed that the speaker did not mention that in-floor heat is more efficient-- because it is NOT more efficient. Electric heat is always 100% efficient. Marketers in the US keep pushing that in-floor heat of any kind is more efficient but it is Not. In-floor heat is Less efficient if the warmest thing in your house is the floor and it is in contact with or not well insulated from the ground beneath it.
I just want to mention that at 6:40 when it shows the temperatures 20°C is actually 68°F not 28°F 😅
Well spotted. Guilty of copy paste and not editing the value.
Ice maker. Element allows comb fingers to easily scoop out the ice cubes.
But if you coal or petrol to produce electricity ... solar panel and wind farme pollute also (rare minerals) best is nuclear
2:34 Saying that higher resistance = more heat is technically true, but in practice it's not.
If you have a circuit which only consists of resistors, increasing the resistance decreases the current flowing through the circuit.
Since Power = Current^2 * Resistance, this leads to less heat being generated, not more.
i think it's when talking about a single element's resistance
Man like anthony mcalmount
3:58 you "forgot" to say that the price of electric heating is 3-5x more expensive than conventional.
It's "popular" because it's cheap to buy, but when you get the electricity bill you'll see that you made a terrible purchase.
The only economical way for heating with electricity is a heat pump, where you get 3-5x more heat than an electric heater with the same amount of electricity spent (or spend 3-5x less electricity for the same amount of heat).
Not if you generate your own energy. My home and workshop only have an electric supply, no gas at all. It's safer, I don't pay for a gas meter, I can remotely control it and schedule much easier. Heat pump is a good option, it's a little more difficult to fit and it only warms the air which rises. Underfloor heats the entire floor which then rises up more even. There are pros and cons to each of course.
@The Engineering Mindset if you generate your own electricity an electric heating is even worse investment because you have to scale up your whole power generating system 3-5 times more than you would need for a heat pump heating.
There are several different systems, the one you described (air-air) doesn't "only warms the air which rises", it warms the room via convection (a fan circulates the warm air thru the whole room).
It's the cheapest system and can be installed easily and cheaply almost anywhere in a few hours (it's probably cheaper than an electric underfloor heater with installation).
Then there are heat pumps that heat the water (air-water & water-water systems) which is then pumped thru underfloor pipes and radiate heat (the same way as your underfloor electric heaters).
Another advantage of those heat pumps (aside from massive 3-5x electricity savings) is that you could install a cheap buffer (water tank) instead of expensive batteries when your power generation system underperforms.
All heat pumps have a built in thermostat, timer/schedular and remote control (and WiFi control, except maybe the cheapest ones).
Sure, I have covered all that in the heat pump series. But for example, in my apartment, I can't install a heat pump. I only have electric heating (no gas supply) and millions of people are in the same scenario. I have the option of a wall hung electric heater, a plug in heater or underfloor heating.
2:07
only kinetic energy transfer inside the wire?! i thought it was also discharge. im dumb,tho.
plug in air freshner.
Only 100% efficient?
👏👏👏👏👏🙌🙌🙌🙌🙌
Calling electrical heat nearly 100% efficient is quite a mental leap. Yes, it’s pretty good if your measurements start at the switch on the wall, but when you consider generation and transmission, which are indispensable parts of the system, the efficiency is terrible.
Sure, in this sense, we are only talking about the point of use. Because the electrical energy consumed is almost entirely converted to heat in the space, whereas a gas boiler has heat loss through the combustion ventilation. We can use locally generated electricity, but it is all dependent on the installation location. A family home can use solar power, perhaps wind, but a block of flats is limited. That's a case for the end user and is beyond the scope of this video. In the efficiency discussion we have only displayed values for point of use for both gas and electricity.
I concur, this statement is extremely misleading especially when used in the context of heating apartments since using energy sources to generate that electricity (instead of heat) are almost always extremely inefficient (~30%) in comparison
@@EngineeringMindset I appreciate the response. For whatever reason, I’m seeing a lot of propaganda in favor of all-electric houses lately, plus a turn towards electric cars, and it’s worrisome from an ecological standpoint. Not only will we be getting more weather related disasters, but if people are totally reliant on the grid for literally all life-sustains activities, that will amplify the effects of a power outage. Imagine the Texas outage but nobody could travel either.
Not to mention that the power will ultimately come from either fossil fuels or nukes.
You are nitpicking....offcourse everyone understand your concerns although ridiculous if overstretched like you do....electricity is mostly lost as heat even through transmission wires and switches
@@twestgard2 part of the issue with Texas is that we’re too cheap to put electric heat in key equipment. Most normal substations in the civilized parts of the country have no issue with the cold. If you are implying that the electric grid was the only utility in Texas that failed then you need to stop watching Fox News.
A COP of 1.0 is horrible!
Electric heating through bitcoin mining.
Using generated electricity for heat when natural gas is available is just the worst in terms of responsible use. Electrical/mechanical energy are the most useful forms of energy whereas heat is the least useful. Taking heat from a fuel and converting to electric or mechanical and then using it for heat again is just irresponsible.
That problem is better related to the cost of renewables, grid supply mix and to the annoying dependency on gas-rich grid in the UK, meaning that both gas and electricity mostly have the same source and thus there is a "mechanical to direct distinction" For instance, in a country like France where the majority of constant power is nuclear, or Norway, where hydroelectric power is abundant and storeable, it makes more sense.
Electric heat the most efficient 😂😂😂😂😂😂😂😂😂😂
It is, or at least can be. If you're running a diesel or coal generator then obviously not, but through wind, solar, renewables then it is. Even better if you self generate. All the energy is transferred to heat within the space with electric heating, where as natural gas is energy intensive to produce and distribute, a large part is lost through the exhaust providing no effective heating at all during combustion and it's also far more dangerous, especially in apartment blocks, care homes etc. There's also emissions and risks with poisoning, there's mechanical movement within the boiler which will result in breakdowns. These do not happen with electric heating.
