My dad sold Philco refrigerators in the 60's. We had a defective one that would not cool. The service people first changed the compressor and the problem. The factory gave the customer a new fridge and the defective one was abandoned at the service center. Somebody decided to look at the fridge again, installed some temp probes and ran the fridge. He saw that the temps came down quickly, but temps rose rapidly once the compressor shut down. Turned out the door switch was defective and the 40 watt inside light was heating up the inside. Now...these little heaters just might warm up a room...if said room was insulated like a fridge.

Thanks for the video. I've spent an unreasonable number of hours of my life trying to politely inform people that there's no such thing as a more efficient "electric heater" only to have friends and family continue to fall for this stuff. No one pays for ads in order to tell the truth. I'll never understand why people continue to believe the ads that they see once they're beyond the gullibility of childhood. I like "ceramic" (PTC) heaters and have one pointed at my feet at this moment, but they'd gotten smaller and more expensive even before 2020, so now it's even harder to find decent ones. I recently took the heater core out of a new junky one and installed into a 90's model that includes a washable filter as keeping dust out is key to the longevity of these. At some point companies realized that they had no incentive to include the dust filter as removing it made everything less expensive while also hastening the death and replacement of the products. And to further incentivize this behavior, today's customers no longer even realize that these once came with filters, so they simply think it's normal for PTC heaters to fail rapidly. That's how you slowly, but surely, push the consumer market towards lower and lower quality and value. This is a bit like taking the spare tires out of our cars; eventually you've brainwashed the entire population to accept that they need AAA to fix a flat when their parents simply swapped one out with a spare and kept driving. Many consumers will even call this "Progress".

the older inventor was a jet engineer from the North. They claim that it will save you thousands of pounds but show American Dollar bills being counted out. Why was he expelled three days later for refusing the funding and going down in history? If he’s at school why does he have a professor? Aren’t they normally found in universities? He reverse engineered technology used in all heating systems; so what did he invent them. It raised the temperature of the classroom significantly in just a couple of minutes. To raise the temperature of anything by a certain amount you have to put a certain amount of energy into it, which will cost a certain amount. How can you heat a large room in a couple of minutes without it costing a lot of money in theese days of high energy costs? The same student invented the opposite device to cool his classrom in the Summer at virtually no cost compared to conventional air conditioning the cold air, while the heater recycles the hot air. He was also expelled for the cooling device, so he was expelled twice? Why would the school expel him for saving them large amounts of money? The heater may have some merits for heating small areas, but why have these adverts not been banned?

When Clive says his finger do get cold, you know a glass of water on the bench is probably turned to ice. Thank you for the tear down and explanation of these heating devices.

I've seen these plug-in heaters in mail order catalogue, and it can heat your house with this one heater. Yes, if it's a very small house and someone like me will forget to turn it off

If you need a bit of extra heat and are spending an extended period in one spot (e.g. watching TV or working at a desk), an electric throw blanket is worth considering. They use little energy compared to a space heater (100W-300W) and they're surprisingly effective when draped over one's lap. They're also quite inexpensive to buy, many are machine washable and they feel nice.

Bear in mind small fans are always noisy, so even on low speed mode you might find the noise annoying if you're trying to work for example.

I would be interested in a more premium version of this heater that has a silent Noctua fan , and a small battery for the cool down cycle in case power fails unexpectedly (with the more common power outages because power companies actually started to maintain the power grid to not have leakage because the cost for power has risen so much) amd maybe a separate and replaceable room thermometer for the more accurate room temperature maintaining, and a more needed heat resistant heating element holder that can save you in case the battery is empty and the power fails, in case over night the powers flickers on and starts the heater then before charging the battery enough the power will go out again and the cooling cycle stops in a few seconds.

Test how safe it is by bypassing the bimetallic cutout and connecting it directly to mains without the fan installed to see if it reaches some temperature and stays there, or just keeps getting hotter until flames appear.

Freezing cold nights? Let's fire up a tube amp and make some racket... :) Good tips for staying warm, and I have to add one more: layers, layers, LAYERS. You can never overstate this. What keeps us warm is heat insulation from air trapped in the materials - the more of it, the better, so two blankets will work way better than a single but thicker one. Air is also why animals (and people) use fur for staying warm, and why styrofoam works as an insulating material. Nice PCB design there, but with such a small power, I agree these heaters are rubbish. May be good for drying but not much besides that.

After just coming out of a winter where the state government had to suspend the electricity market to prevent the kind of blackouts they're threatening in the UK, I can say that you really can save money by making some minor changes to your heating habits. I simply rugged up a little more, turned the thermostat on my heater down a little, and switched it off when it's not needed rather than just leaving the timer to switch it off at the regular time. With just those basic changes, my winter bill was 10% less compared to last winter, despite the fact that the energy price has gone up by about 10%.

Very useful, to learn whether whatever you are looking at, either actually work or are safe or likely to blow up. I have been ripped off by a couple of these mege advertising, hype type products and i use you and your wonderful comments to learn a lot. Thanks.

It's a lot more efficient to use a directional IR heater to heat just yourself if you are stationary, rather than heating the whole room. You get toasted more on one side, but nothing is perfect...

Also have two vintage Phillips Infraphil lamps to shine at my feet if needed later . I've got to keep my heating consumption to a budget of +-500w . Also added king size heated underblanket on sofa which is often more than enough heat comfort and only consumes 80watts on setting 2.

Hi Clive me again 🤣, I have heating in my shed in the way of two 500w electric heaters which came from a friend's flat that he no longer wanted. Which when I tried them first before I installed them in the shed discovered that the internal thermostats were knackered so I have put them on a separate thermostat and all is good. The heater that you have reviewed I also have, which I bought from the shop called the range for £19 I have angled it down towards my feet as a foot warmer while I'm sat in the shed and it's absolutely fine. I have had it now for about 2 years without any issues my feet are well toasty 🤣

Better to switch to infra red heater bulbs used for small pets/animals, dark beamer. At 250W it's about a third of the power usage and it is quiet. At 13⁰C room temp. it gives the comfort of a 20⁰C heated space at a fraction of the cost as it doesn't heat the space, just the area you're sitting.

If the thermostats work properly they should save money by virtue of the fact you don't heat past the set point.

If they made the fan quieter then I would say that it is usable but it's still too loud, it's a little quieter than a hair dryer. It does seem to be well built enough, you can even turn the plug, but it's too small to be worth using and it's stuck to the wall instead of being able to be placed where you need it to. Several years back, a co-worker of mine bought a small heater to the office and it was designed where if it fell over the thing would shut off. I thought it was a neat feature. This one would need to have the miracle efficiency that it was advertise to be usable for me.

10:15 the disadvantage of your redesign is that if one LED fails open circuit then both stay dark. My guess is that their design is to ensure that the indicator continues to light up even if one or other LED fails. They each have their own resistor so that if one fails short circuit it doesn't steal all the current from the other one.

Just a hint for anyone that has a standard 2kw fan heater and wants to reduce it to a 500/1000w heater, or even further to a 500/250w heater: 500/1000w: Swap the "position 2" connection and neutral around on the element, this'll run the two elements in series for the low power setting, and run a single 1kw element for the high power setting. 250/500w: Move the neutral to the "position 1" connection on the element, this'll run the elements in series to create the high setting of 500w. Put a 3A diode in series with the "position 1" output of the power switch and also connect this to the "position 2" connection on the element. The diode will run the element half-wave which averages out at using 1/2 the usual power, creating the 250w setting.

If you can afford the huge outlay for a split system they are definitely the cheapest way to warm a room, you can get 3kw of heating with less than 600w input. If you are running the heating daily it will quickly pay itself off over a year or two.

I had to look what that was. In winter my Father used to put one of those under the bonnet of his car overnight (which was kept in a detached garage) so it was easier to start in the morning.

When you turned off the light, it was the first time I could clearly see what the HOPI was indicating. Normally the light and HOPI flicker so as not to be visible. I thought it was the difference between 50 Hz and 60Hz, Not so.

I'VE got a silvercrest like the white one, very similar, bought in lidl i think. excellent little heater. warms the shed nicely. never on for more than half an hour or so

I've got a couple of these heaters. I've got them primarily as emergency heaters, in the event of a boiler failure, etc.

A lot of bells and whistles to make a fancy resistance heater with a fan. .

There are ads for these type of plug-in heaters that make ridiculous claims and follow typical scam product script. So good to see that they do work, at least work for a small room.

I have a heater exactly like the white oval-shaped one (but branded under "Russell Hobbs"). I was unaware of such marketing. I just assumed 500W meant 500W. It's actually ideal for this well-insulated tiny outdoor bathroom we have with no other heat source since it doesn't share a wall with the main building of the house.

Great breakdown on these.

Awesome I don't know how I missed this video but I've got these heater 4 to be exact I use them to heat a Green House and for my purposes they work shockingly well I can't wait to see you take it to bits 😊 the button on the back rotates the plug if you push it and hold it and turn the plug.

Years ago I had a 1500w "ceramic" heater with NO cool-down cycle. I wonder which is more damaging to it, let it cool with no fan, or have cold air without heat blowing through it (like yours).

It reminds me of all these videos popping up online of candle heaters. I worked out that the cheapest wax you can buy works out to about 25p/kwh (buying 200kg in a bulk order). Tea lights work out to about 84p/kwh... If you have an oil burner a 1lt bottle of cooking oil is currently around 22p/kwh. Obviously burning anything in your house is going to massively reduce air quality though. I think the cheapest form of heating currently is probably coal, ranging from 5-8p/kWh. Plus there's off peak electric which was around 7p/kWh but not sure what it is these days... You can also use a heat pump with off peak for extremely cheap heat.

I have a little 200 watt heater in my kids room. when the temps drop below freezing it can get a tiny bit chilly. It has three settings, fan, 75 watt heat and 200 watt heat. I turn it on at bed time and it keeps it comfortable overnight. I have another in our teardrop camper. the 209 watt setting will make you sweat in that !

I would worry about the mechanical load on the socket outlet. Sockets are not designed to support heavy lumps. Modern plug-in switch-mode PSUs aren't too bad, but these heaters must be comparable to the old PSUs with heavy transformers.
