Infrared heater efficiency -- how much is radiated infrared?

Testing the efficiency of three different infrared heaters. All electric heaters turn all the electricity into heat, but for infrared heaters, how much of that heat is really radiated infrared?

A company would have to be quite confident to contact Matthias about testing their product.

The term “quartz heater” is a marketing term that came out in the 80s (late 70s ?) when they started selling heaters where the element was contained within a hollow quartz glass tube. That’s opposed to the standard nichrome wire wrapped around a ceramic core. The one that Mattias referred to as the “old fashioned” one was the ‘wire wrapped around a ceramic core’ variety. The others were ‘quartz heaters’.

Tip over protection is very often oriented for face down tipping since that is the dangerous direction.

I was surprised that Matthias didn't mention or show off the high-tech automatic infrared heater aimer! Especially when it came to the "body presence sensor" of the new heater. The heater aimer is a great video.

Oh... A thermodynamics experiment! I really like it, Matthias! 😃
Excellent work!!!
Stay safe there with your family! 🖖😊

The tip over protection might just be if its facing down against the ground or maybe it's just a thermal sensor?

Even though Matthias was sponsored by one vendor, the way he sets up the tests makes me trust the results :)

I love my radiant heaters. My favorite is a little 250/500W unit that I keep under my desk so I don't need to turn on the furnace while working.

Hi,

First off I really love how I’m depth you go with the science, your really doing an incredible service wirh your style of teaching and real data collection.

I would love a 1min summary at the end of each video that clearly articulates the pros and cons / best choice for x situation.

6:53 i was wondering why Matthias called the patio heater a "Bluetti" instead of "Maxoak". I googled and found out Bluetti is a branch company of Maxoak.

You weren’t lying about being bias. Love you and your vids regardless.

Could you ask a kid imagine going over to Matthias' house and being wowed by all of his interesting projects and conversations ?

When your mommy came to pick you up, you'd probably want to stay overnight.

Would be fun to test "Far Infrared" heaters as well. They are in theory ~98.5% effecient versus the ~80% for standard heaters.

[fairweatherfoundry]

Not all of the bulb power goes into infrared, so the efficiency comparison will be off a bit, but I think its still a good estimate. Great video!

[shookings]

"And that, I think I can observe".
You're a consummate scientist, Matthias.

Do these heaters emit in the far infrared or near infrared ? Thanks

[rikityrik]

I’m I guess ignorant on these infrared heaters, do they perform better than a 1500w ceramic heater? I saw some videos saying the 5000 watt ceiling mount forced air heaters are the way to go. But worried about the electric bill collector lol

[DamianReloaded]

if you are going to stay there permanently and considering how much wood you have around, wouldn't you consider running some pipes and having central heating? You seem like you could pull that off yourself and it would be a heck of interesting project to look at.

This test seems to be reasonable, but would it be better to use a fan to solve the convection effect?
