I hope this video was helpful to keep you warm this winter. I look forward to hearing your feedback and suggestions. Don't forget to join the competition: ***WIN*** for Free enter the raffle competition here: raffall.com/joshuadelisle There are linkls to everything else in the description. All the very best Cheers J

[@plaguezero]

a suggestion along similar lines to personal heat is to use vivarium heat pads and place your bare feet on to them which will warm up your feet and your blood which then circulates and warms up your entire body and these can be USB powered and plugged into battery banks

[@plaguezero]

I see now you did cover something similar, I should have waited I forgot how thorough you are

[@joshuadelisle]

@@plaguezero thank you. Yes that worked out well for me at the end of the video. Cheers J

[@plaguezero]

@@joshuadelisle I got to the end and this video is as high quality as the ones I saw that made me want to sub and you're a brother in Christ to boot and I like the direction of your thinking with wanting to experiment with water heating... you could probably make use of computer water cooling pipes although I'd check first whether they're rated for heated water to the temperatures you're likely to encounter, typically as you probably know they carry the heat away from the components in a PC and those can get rather toasty. I look forward to seeing the next video

[@simonbroberg969]

been using them for two years now, great when on the motorbikes (or using my mobility buggy) Looks you found some nice ones. I recharge my battery packs on my solar when I can, but only a small set up, so do have to use mains a lot too. Problems I found out were the buttons stop working after a small while, a lot of them just pull off from the wires which is a pain, but with the prices as they are, they are easily replaced.

[@InimitaPaul]

As a motorbike courier I have the cheap vest, heated insoles, heated gloves and mini heated pads I can put anywhere (all from Temu). I find the neck heating on the vest amazing, I don’t notice the body heating but it has a reflective layer on the inside and that I do notice for containing body heat. The heated insoles don’t keep the toes warm enough so I’ve resorted to the toe warmer version of the hand warmers that are chemically activated by air and they’re just amazing, even the cheapo ones I bought; you just have to give them 5 minutes out of the boots to activate properly. The cheap heated gloves are great under 40mph with handlebars muffs around 0 degrees but over that speed or lower than 0 I put the pads in the gloves too. I use a 27600mah power bank with modified cables and connectors going to everything and on full the gloves and vest alone blast through all those mah in around 8 hours. I’ve taken to relying on just the neck and glove heating most of the time with toe warmers, ah the toe warmers!

[@joshuadelisle]

Well done. That's awesome. Cheers J

[@TheOriginalEviltech]

I just installed heated handlebars on my enduro bike. What a difference it makes! In ambient temps of about 4-6 C even when wet and covered in mud those two heaters which total about 120W on max are enough to keep me warm enough to be comfortable going about 60-80 km/h! The gloves i use have a really thin inside and well insulated and windproof outside.

[@campandcook3118]

​@@joshuadelisle the navy did some great studies on heating systems for core, head and gloves. If you core and head are warm enough, the body does not restrict blood circulation to the arms and legs to slow heatloss. A warmer core keeps your fingers warm. I use the silicone encapsulated heating pads for diving. The 100m rated battery tank outside the dry suit provides 6,9 or 12V and keeps me warm in winter, especially during decompression the end of the dive (better blood flow in tissue improves getting rid of nitrogen)

[@kevinmcgrath2077]

Cheers Josh, I suffer badly from arthritis of the knees and have to live with constant pain. Hot pads from the microwave give temporary relief until they go cold. I saw this video, bought some pads and a battery, sewed them into 2 knee bandages and now sat here watching your channel with warm knees and no pain. Thanks so much for the idea!

And as true as all you've said is, isn't it extremely sad that as British people we're now planning on wearing heated clothes and using a dehumidifier just so we can afford to not be cold in our own homes and not then have mould and damp....while the energy suppliers make record profits and we're being charged more per unit than anyone else in the world.... What's happened to our once great country?

[@joshuadelisle]

Yes I thought I would hold back on a political rant for now. Maybe in my follow up video I'll share my 2 pence on the subject. Cheers J

[@Xanderbelle]

Ffs. What ever happened to personal responsibility. These little heat pads are great, but oh no, there's always some whinging halfwit... it has to be big energy or the govt or policemen are too young or working 25 hours a day when I was a lad

[@Baxtexx]

Same in sweden..

[@updlate4756]

Well we know what happened to our planet... human beings overconsumed resources and energy, generating massive amounts of greenhouse gases, which could potentially wipe out billions of human beings, animal and plant life... if not worse. Cheap energy and resources and high wealth economies are the worst things that could have ever happened to our planet. The British have been some of the highest emitters / polluters on the planet since the late 1800s. North Americans are even worse. IMO, people looking for ways to save energy, while not giving our money away to greedy energy companies, isn't sad, it's something to be proud of and hopeful about. Saving money is just icing on the top. What is sad is how many people simply don't care enough to do anything to lower their footprint. In the past two years, I've had multiple friends decide to become frequent flyers. Not because they need to fly for work. In two egregious examples... two of my friends each have a favorite band. One started to fly around the US multiple times in a single year to visit her favorite band, dragging her husband along with her. The second friend some how got it in her mind that this was a great idea, so she started to do the same for her favorite band as well. Likely thousands of pounds of CO2 just to cavalarly fly around to see bands they've already seen multiple times this year, and who even visited our region in the past year. But it's not their fault... it's the energy company's fault. It's the airline's fault. It's everyone's fault but the wealthy individual humans who are consuming and polluting far more than the world can handle. And their footprint isn't a mystery. Environmental conditions and impact are all over the internet for everyone to see. I myself share all the things I do to conserve energy with my friends, and rather than take such ideas to heart, they're usually laughed at, scoffed at, or called crazy. One such simple thing... I stopped flying for vacation. Another thing, I ride my bike instead of driving every chance I get. I conserve water .I turn the HVAC down and wear warmer clothes. These actions are considered crazy. I do love all the westerners who have far more than the majority of the people in the world complaining when energy prices go up. If they have to spend so much on energy, then however will they afford their annual trip to another continent for vacation! This isn't a corporate problem... it's a greedy human problem.

He was casually wearing the jacket at the time waiting for effects. He just calmly took it off 😂…

Carpenter here working in unheated workshop all day. Been using these for years, the cheaper under garment ones are best as you can wear usual top layers over it. For feet the heated insoles are better than socks and can be purchased with battery packs (From amazon) that last about 10hrs on medium which just about lasts a working day for me. Have been using the current set for 5 years and still working perfectly.

As an exceptionally skint person, I must say dehumidifiers, heat pads, hot water bottles and electric blankets are the only thing keeping me solvent.

[@lightningslim]

Being an old geezer on a fixed income, I can no longer afford to run my single gas heater (in the kitchen) all day to heat the whole (open plan) small house. It is, however, relatively well-insulated (1982 build), so I have created curtains as room dividers and do not use the gas fire in the kitchen at all. Instead, I have purchased two small PTC heaters, one in my lounge (where I spend the bulk of the day) and one in my bedroom (where I spend the bulk of the night!). I have found that at current external temps, I can run the lounge heater for an hour or so, and the lounge will stay at 17/18°C for the whole day. Similarly, just before bedtime, I run the bedroom heater if required. I bought a very cheap USB waistcoat from Temu (more out of curiosity than expectation) and was surprised at how useful it is. It is essentially the same as your cheap version, with the comfortable lining. Of course, I wear it under a thick jumper, but I also find that it doesn't need to be active for long to warm me up, yet it maintains a comfortable core temperature without consuming much power - my battery pack lasts several days! Love your content and I approve of your philosophy!😀

I think a rug or cheap floor heating that's powered through electricity might also be an option if the bottom is properly insulated (or DIY products for heated car seats for their seats at home)

[@joshuadelisle]

@Autschbruv the only issue is electricity is £0.25/kWh which is the most expensive form of energy. I recently reviewed a diesel water heater that runs on heating oil that is £0.05/kWh and used it to do mock underfloor heating.

Just today I wore my new cheapo (£20, amazon) 'Wrei' heated vest for the first time : As a photographer, I specialise in surfing & wildlife & it can get damn chilly when sat on a Cornish beach in winter, waiting for some action; not to mention a wind-blasted headland trying for some storm shot; which is not relevant to today, so we won't mention it. I wore mine over a base layer & snug hoody, with a medium fleece over the top & was toasty: In proper gharstly conditions I have the option of a thin puffer & my trusty Zone-3 parka, plus (Cornish weather) full goretex shell.l I didn't notice discrete hotspots, just a comfy glow all over my torso on the low setting: My 20,000mah power bank showed ~ 80% remaining after 2.5 hours. I also carry a pair of usb hand-warmers (5,000mah each) in my jacket pockets but didn't need them today. Apropos of nothingness, I'm 75 years old, which probably explains why I get cold when not moving about.

I love your videos mate. I seem to remember the Americans (it might have been the US military or maybe NASA) did some tests where they put test subjects in cold water baths to see how long they could tolerate low temperatures. They then provided the subjects with heated copper tubes they could hold in their hands. That was the only heating source but they found that subjects could tolerate low temperatures much longer. It was based on the assumption that your hands (and hot the top of your head) are the biggest heat absorbers or radiators in the body. It worked the other way too - cold pipes for subjects in hot water baths.

I bought 3 pairs of the heated inner soles to insert in clothes, £12.50 shipped.

During the shutdown I was eating in my car at work because I didn't trust the lunch room, being in Canada and winter (-20C is fairly common) and not having great heat in the car I bought a heated hoodie. (The battery that came with it only lasts about 3 hours but if you only use it during break time you get about a week out of it.) Best thing ever! I bought a second one for when not at work (I don't want to smell like factory at home or out and about). I prefer the ones that use the 5V USB over the 7.5V 4mm plug just because spare battery packs are easier/cheaper to get, yes they don't get as hot, but a spare battery (and more energy storage) is well worth the trade off (especially if you have an outer layer on).

@@joshuadelisle One thing I forgot to mention I also bought a Battery powered handwarmer at the same time (basically a standard power pack with a heater built into the case in a pleasant shape) and that is even better than having heated pockets (because you can stick it in any pocket of any jacket or holding it like a hot cup of tea). I've even seen someone use one to keep drone batteries warm on a snowmobile trip (several hours on a -10C day out in the wilderness, the cold would have drained the batteries for the drone before they would have been used).

I tried using the old tea candle and some terracota pots heater trick... its like trying to build a perpetual motion machine.. wasnt worth the time or cost of the pots, so i settled for a gas bottle heater, the old granny ones you used to see with the 3 ceramic plates. gas bottles are a rip off lol.

[@joshuadelisle]

Thank you so much. I will definitely look into compact cost effective methods of dehumidification. We have single glazed windows and with all 6 of us we produce a lot of moisture. Sweat, breathing, cooking, showers etc all add up. I've fixed the issue with ventilation, I have a very low watt fan pulling filtered air from the attic and pushing it Into the house which circulates and exits out of floor vents. A lot of heat is lost in the attic as it rises so it acts as a simple heat recovery system at the same time as pushing the heavy cold air out the floor vents. My windows act as dehumidifiers because the water condensates onto them, I bought a window vac which I use to gather up the water droplets in the morning and late evening before it drips, it's surprisingly very effective and once collected takes a long while before the humidity rises. I would recommend monitoring the humidity inside and outside and test a few methods. If outside is lower in humidity then a circulation fan might be ideal. All the very best. Cheers J

The main reason the elderly like it warmer is that they have lower metabolism and just output less heat energy. They often also have less fat too (as natural insulation). So they genuinely need a slightly warmer environment to feel conformable. I enjoy watching the way you follow your curiosity and test theories (reporting both success and failure).

I haven't seen the silicone pads before they look quite handy, you can also get usb heated sleeping bags and 12v blankets quite cheap. Regarding trying other methods pumping hot water is an interesting idea, also using something like a sand battery maybe. In Germany they have sleeping pods for the homeless called ulmer nests, they are insulated pods with solar panels and led lights inside. At the cheaper end there is another one called the Iglou its an emergency shelter made from foam. Combining a cheap shelter with solar usb heating or similar would probably save many homeless people in winter. It would also make winter camping enjoyable, better than freezing your nuts off lol.

[@mutantthegreat7963]

Also worth noting that in the winter, when the sun is out during the middle of the day, it's good to air the entire house, even if the air is colder because the relative humidity is very low, sometimes around 40% meaning that when it invariably warms up again after the windows are closed, you benefit from a warmer feeling. They say that every 4% decrease in humidty feels like a 1 degree C increase in temperature.

[@joshuadelisle]

Yes however the inefficiency of a mechanical design you're referring to is mainly energy lost as heat which in this application is helpful. Electricity from the grid however isn't efficient at all, the steam turbines are only 40% efficient, solar is 20% efficient and 20% on top is lost through the grid as heat from transformers and wires. The idea is to reclaim heat from free resources using a water cooling system which is very effective. Cheers J

You can get liquid cooled racing jackets from the same place you got the heated vests, and there's no saying you can't run warm water through them instead. I'm in the process of making a water cooled jacket powered by the guts from a compressor refrigerated cooler. I'm going to remove the compressor chassis from the cooler and run the refrigerant through a brazed plate heat exchanger.

A further set of handwarmers would fit into the front pockets of the gillet. My hand warmers last over 12 hours on the low setting. On chilly nights, hand warmers go inside: a) a loosely knotted sock or b) small neoprene pouch or c) tiny tent-peg bag that sits fairly securely under the quilt at the edge of the bed. They operate like a low power hot water bottle that can be switched on or off when required.

That's awesome. I have a Zippo hand warmer that runs on lighter fluid. It sounds dangerous but it's actually really good and very cheap to refill. Cheers J

I use a desiccant dehumidifier as a heater. It gets my room up to 16C and humidity right down, all for 350W. I also wear fake sheepskin trousers and top, and a heated jacket when it gets exceptionally cold. My bills are mostly standing charges.

I have a cheap vest similar and it's great for going under things. It is a fixed size so that adjustable one may be a better bet for folks esp with Chinese sizings. I also have a cheap (~£35) padded jacket, which is great too and I wear a lot at the moment. The big downside with it is the seams are not well stitched and I have already had to repair a couple. After seeing you compare to the expensive one I am left feeling I just buy the cheap ones and replace them more often. Overall, I find you feel the most heat the closer it is to your skin, that's why the neck feels so hot as it is directly touching the skin.

[@richtame2501]

This sounds really interesting as I have Ankylosing Spondylitis (neck mainly)(I think?) Arthritis etc. I can’t move my neck at the moment and have a fan heater on it whenever I can. Luckily, we have solar and a battery. I am going to adapt a car battery also and bolt it outside. I am on morphine for pain in back , shoulders and neck. Add needing new knees. Im 56 btw. Love your channel and you are obviously very clever. You are similar thinking as myself. I have a large workshop at home as I will never live to claim my small pension anyway due to Crohn’s and Primary sclerosing cholangitis (PSC) all are related. Keep up the good work.

[@joshuadelisle]

I pray for your recovery if that's possible. The ororo was fantastic on the neck but just too pricey. I think a DIY version that can be placed exactly where it's needed maybe best. Cheers J

[@chris993361]

I would definitely be interested in seeing a solution with flowing coolant through it. Something that interests me is something like a powered exoskeleton or power armor and I've always thought if I did that it would need a liquid heating and cooling solution like that. So it would be neat to see it work in any context.

[@1978rayking]

A few heat pads in a bed of sand and bedding on top with a heated blanket, a huge solar system even the sofa could be on when watching tv, the vest would be nice for portable around anywhere. A portable diesel heater can be used for a half hour or so when liked if you have a steady amount of money for fuel so on. I bet people could get away with some back up generator systems two or so for good measure and some smart batteries with a solar system the bigger the better for bad weather, because a big systems will still produce power on cloudy or winter days when cleaned.

[@joshuadelisle]

Sounds like a plan. Cheers J

yep, you can change the volt or amps to change how hot the pads get, for safety you could silicone onto the pads some Normally Close Temperature Controller Switch KSD9700 that are rated to stop the power when the pads get to a certain temp. they also make 12v XH-W3001 current limiters based on a temp probe.

Been thinking of getting one for some time now, thanks for doing a test. Some flexwing( microlite) pilots use these when flying. Not sure which version. However they are handy as they draw very little power considering the output from the aircraft is small, so power usage has to be kept to a minimum. If interested a chap called Paul Hamilton did a video about this.

[@TheVenerableMrKrieg]

Probably worth noting that as far as resistive heating goes, it's 100% "efficient". Which is to say it's not efficient, but it also means that if your resistive circuit is sucking 10w, it's giving you 10w of heat. If it's a bunch of pads and so a larger total area, the nominal temperature will be lower, but the _total heat generated_ will be the same. If you're a big fan of having some very noticeable warmth on specific spots then fewer/smaller elements will probably be better, but otherwise if you're using the same amount of electricity and the elements are only reaching ~40c, you're getting the same amount of warmth more gently. If either solution is going to be under other insulating layers, the lower temperature elements is likely to be more comfortable over time (less likely to cause heat rash, maybe less sweat, etc), even though the higher temperature pads might initially seem more appealing. The rest of this is gonna be more technical, but for reference, 1w of heat is about 3.4BTU/hr. Similarly, ceramic/oil heaters will pretty much all suck down a standard amount of power (1500w in North America) based on regulations for what you're allowed to draw from a single outlet, and while they may be different sizes and say different things about being able to heat a given space, if they consume 1500w they will generate ~5100 BTU/hr no matter the price of one versus another, with the only practical difference being included safety features and whether they have a fan for better circulation. This is true for all convection heaters (and similar for radiant heaters-- convection being things that get hot, primarily, and radiant being infrared heaters, although both kinds technically do a bit of both). For anyone wondering, heat pumps sidestep a lot of this by spending their energy simply condensing the energy in the air. Electric heaters just pour that electricity into the air as thermal energy, while heat pumps take the thermal energy in the air and move it all to one side, giving you some hotter air and some colder air. They're designed a little differently but it's functionally the same as taking the hose on your portable AC unit and pushing the cold air out the window and just letting the hot air vent into your room. This allows heat pumps to hit efficiency ratings of up to ~400%, which sounds like bullshit but it's only because there's a ton of thermal energy in the air even at 0c (absolute zero, or "zero thermal energy" is −273.15c, after all!), and since we know that 100% efficiency is taking 1500w of electricity and creating 1500w of heat energy (~5100 BTU/hr), we know a heat pump that can collect ~20,000 BTU/hr for and takes 1500w to run is about four times as efficient as a comparable oil/ceramic heater. All this to say, the thermodynamics for this kind of stuff isn't actually too complicated and just a little knowledge can go a long way for figuring out what kinds of solutions might work best for your situation or goals. Good video, in any case, and I really appreciated a good chunk of it was about how to set up your own stuff!

[@SgtSkrog]

These work great, I also use heated wraps and blankets with timers. Had an RV, and if I woke up at 3am and was cold, I just hit the switch and went back to toasty sleep in a few minutes. Having a timer is a good idea if it is an option. It saved a ton on propane costs instead of running the furnace all night.

[@joshuadelisle]

That's great. I'm thinking of introducing a temp sensor that kicks in before I feel the cold. Cheers J

[@SgtSkrog]

@@joshuadelisle I also have done that, I use a small space heater next to my solar battery that shuts off at freezing. So it kicks on to heat the air around the battery automatically when needed. Auto on and off

[@WilliamAshleyOnline]

If you use a wool sweater it will keep so much more heat in... beat in mind it is the fluffyness and knit airpockets ect.. that let heat be trapped in something like wool, it is that natural air barrier that traps the warm air in. Likewise if you put a non breathing barrier like a wet/wind breaker overtop it will trap heat in because the air cannot circulate away from your body. So having the vest as a layer in an overall insulating setup can keep a lot of that produced electric heat trapped inside.

[@NathanNostaw]

I loved your videos of smithing, metal working and design. Do you jave plans to do more of those videos in the near future? Being in sub tropical Qld Australia, I have zero interest in heating, and even less interest in thinking about it when we have humid 30+ days at thos time of year. :)

Excellent, well thought out experiment, good job! However, don't underestimate the efficiency of thermal underwear like Damart. Wearing a full set under layered clothing and, if necessary, a hot water bottle strategically placed in my stomach, I can stay warm all night for zero cost apart from the initial outlay. If physically active, there is no need for a hot water bottle as you will be generating enough heat to keep you warm without supplementing it.

Maybe target heating where the blood is close to the surface of the body? Then your blood moves the heat around the body? I'm thinking arm pits, inner thigh, neck, and wrists? In theory your body will cut blood flow to your fingers and toes if it's loosing too much heat, so if your fingers and toes are cold then heating your body elsewhere can make them more comfortable. At least up to the limit where your foot is submerged in a fast flowing ice cold river or similar, I guess, and your body can't deliver enough heat to it to keep it warm?
