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
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.
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?
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.
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
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.
what is better suited to protect a 3 phase heating element ? fuse or a miniature CB ? I've seen some machines using motor protector for heating element although I have no idea why since the inrush current of heating element is supposed to be lower than a motor ?
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.
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.
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.
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.
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)
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?
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 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.
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'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
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.
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
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.
Pure Electric is less efficient than an electric heat pump. And I really dislike floor heating as it heats up the floor and everything that is on the floor. The smell is nauseating to me and Im pretty sure it lifts all the dust and microbes back into the air.
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.
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.
