"Miracle" heater teardown - with schematics

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.

[@screwthishi5thing]

That's a funny story, I've had a defective fridge door switch myself that caused mysterious burnt plastic smells inside the fridge for a week

[@josephking6515]

So the light really *doesn''t* go off when the door is closed. That mystery has finally been solved. 🥳🥳🥳

[@dobythedog]

You can hack a fridge freezer which is stored outside which would normally switch off the compressor once the external temp drops below freezing. All you need to do is link out the door switch to keep the interior fridge light on and the warmth will keep the appliance operating properly as the fridge temp won't drop below freezing.

[@IceBergGeo]

@thomas burns when it's below freezing outside, the compressor doesn't warm up the fridge portion. That being the case, the whole fridge would become a freezer, which is undesirable.

[@IceBergGeo]

@thomas burns your former fridge resides in a garage, if you have both. Helps with overflow, BBQ and beer.

[@antibrevity]

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?

[@TheKnobCalledTone.]

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.

My layout is top duvet, middle sleeping bag, bottom electric underblanket heater.... meaning if the duvet and the sleeping bag doesnt keep me warm, just turn on the underblanket, of which has heat 3 settings, and I start at number 1. It really is so much cheaper in these cost of living crisis to stay warm vs central heating or space heaters. Its almost November now and I've yet to even turn on the blanket. It is currently 18c in my flat, but its only October, lets imagine January and February which are the months you'd really need the heat. Well, watch Netflix/Prime video etc or whatever on a tablet laying in yer bed with a duvet, sleeping bag and an underblankie with 3 heat settings instead of wasting your leccy on heating the room.

Good to hear it’s well made and safe at least. The problem with these heaters with a built in plug, is that you can’t position the heater away from the socket (to where you might actually want the heat). Plus, as you say it’s a slow way of heating up any reasonable sized rooms.

That is unlikely to help you. What people fail to understand is that if you manufacture major amount of electricity from gas, lose most of it in a power lines and then create heat from that, It would mean that heat consumed several times the gas or would consume if you had used boiler in a first place... Adding upkeep to power plants, transformer stations and all of those companies making profit, what you did was to heat your legs for more then the a grade A,B or even C boiler would take to heat hole room...

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.

They should use a rotor lock sensor fan in them for another layer of safety. Say the fan stops working, whether it's seized or the supply to it failed. The processor could turn off the supply to the heater. There is a thermistor for overtemp sensing but if this failed in some way the rotor lock is a good cheap backup option.

@@bigclivedotcom Would the PTC not be sufficient to provide passive protection in this case? Is it possible they engineered it such that the equilibrium temperature would remain safe even without the fan assuming that is that the ambient temperature remained within reasonable operating limits which for consumer devices would probably be in the sub 50C range. The rest of this seems relatively well engineered so I wonder if they may have omitted that feature for this reason as they simply did not envision a situation where the device would overheat to the point of catastrophic failure under expected indoor operating conditions even in the event of a fan failure.

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%.

[@Stoner916sac]

LOL the fan speed is also the heat setting. How it works is if the fan is running at a slower speed its pushing less air through the ptc element but if its runner faster its pushing more air through either keeping it cooler or warmer and thus the power is regulated

[@KevinT3141]

Yeah, I was thinking that too, the PTC should self regulate the power down if the fan isn't pushing all the heat energy out quickly enough. Saves on split element wiring and an extra relay to adjust the power level. I'd love to have seen the Hoppi measurement of the low setting as verification of that thought.

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. (And finally, a floor stand and a small plug extension cable , also a wall mounting option)

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 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.

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.

I live on a boat, and use one of those chinesium diesel heaters (bought them when they were £80 last year) which seems to work really efficiently. I had a friend who was so impressed, that he switched off his storage heaters, and installed a diesel heater in his home, powered by a bench powers supply, with the exhaust going out through a kitchen vent. I've found that with 8 metres of hose (the tumble dryer tin foil stuff) I can keep my boat warm using just over a litre of red per day. This may increase with trying to heat an entire house.

I'd been thinking about getting one of these for a while to potentially use in the car when camping, so made a special trip to B&M to get the 'blaupunkt' branded version of this. I think it will work very well for that intended use, and possibly would heat a small room too. 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. Also the little tab under the plug is not for swapping to other fittings, it actually allows the unit to be rotated 90deg - useful if the intended plug is too close to the floor for the unit to fit in. Also: Clive I am DEEPLY offended by your appearance in live streams. A technical person should only ever wear clothes with burn holes, spattered with unidentifiable stains.

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.

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.
