Were 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 its perfectly fine. Im 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. Im wondering whether medium wave will be optimal for our situation?

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.

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 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

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!

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.

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 = Current2 Resistance, this leads to less heat being generated, not more.

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.

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.

Calling electrical heat nearly 100% efficient is quite a mental leap. Yes, its 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.

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.

I always find it amusing that the same people who outlawed incandescent light bulbs and lectured us to not leave TVs on standby, are now pushing electric heaters, heat pumps and 30kw+ electric cars.

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

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.

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?

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?

We use NiChrome wire for cutting foam into shapes like airplane wings with specific airfoils.
Cool video! Looking forward to your next.
