IR heaters?

Hi all, So I've been searching / reading up on IR heaters and I can easily find IR bulbs /heaters, at 30W+ but the bulb's are pretty big (in regards to what I want). Is there not any smaller-scale /electronic componets for producing IR heat? I know there are IR LEDs but is that the same thing? I'm a bit lost and I swear I came across something before that had an array of small scale IR heating componets, but quite frankly I dont really know what I'm searching for, in regards to a correct name etc... Thanks in advance :)

USB heater

Hi everybody! As sais in the title of the topic, I want to realize a USB heater. Let me introduce you to what I think. Last week, I was in the store near high school with some friends, and one of them told me : "It would be cool if we could heat up things in high school, to have like a mini oven directly in our locker, working with battery." Of course, the idea is not to install a oven in our locker, firstly because it would need an incredible battery, and secondly because it would be pretty dangerous.... So here is the idea : the goal is to heat up at least 2 chocolate breads at 60°C. The heating time is not very important, but it has to be under 40 minutes (a system will start the oven before our break). But here is not the most complicated : the oven has to get its power from a usb power bank(I can plug in 2 power banks if necessary). To conclude, I have to fin a solution to heat approximately 1.5L,( but most of it is filled with air), at 60°C, with a power of a maximum of 20W. I saw things to heat coffee by USB, would it work if I take the heating pad? Also, I would like to know how much power I can  get from a power bank (in W), before it to heat too much.

MRE Heaters

When I was younger, we played with the heating packets from MRE's (Meals, Ready to Eat - Military field meals). My favorite thing to do was to put a pouch inside a plastic container (with a screw-on lid), add water, tighten the top, and wait for the large boom. Here's my question: The heaters release moderate amounts of hydrogen gas once water is added. Of course, with an enclosed container, it will quickly reach pressures adequate to blow a bottle apart (wear eye-wear). But once I joined the military we would add a flame source, so we could see just how large the blast was. I wasn't so sure that flame would actually add anything to the gas explosion. They were sure of it. Is anyone aware if: The presence of flammable gas (exploding from a plastic bottle) with an external ignition source would increase the blast? Or maybe just add another factor to it? I'm sure somebody knows. Every once in a while, though I've been out of the military for about 4 years now, I still find it surfacing from my friends. Just curious.

Hello, just wondering if anyone could post any links or anything about old oil heaters. Not the pressure fed ignited furnace type, but the gravity fed ones with a simple carburetor.

diy pool heater

I have tried so many different ways to heat my pool water and have had little luck. One way I did it was to take about three hundred feet of black 1/2" drip line and run it around the pool rim. I supplied cold water from a smalloutlet attached to the return line,using the power of the filtration pump to move the water from the pool through thecoil and I adjusted the flow to about half of the normal, then at the end I had the heated water re-enter the pool. Iwould say the water got to about 100 degrees, by the time it went through the drip line. The problem is that it wasn'tefficient enough to have any real effect on the pool water temperature which stays at about 60-65 even on the hottest days. I live in the Sacramento area of California, and we get pretty hot summers, usually about 90-105. Any suggestions on how I could make this idea more efficient? My pool water temp is always too cold to swim in, and I have a capacity of 12,000 gallons.

Waste Oil Heater

Hey guys, I am looking for some info on how to take an existing oil burner 'gun' (I have an extra Beckett burner) and rig it up to burn waste oil. I make biodiesel already, but I'd like to try burning some waste vegetable oil and motor oil as well. I figured since I have the extra gun, I might as well try it on that. I'm assuming I'll need to set up a pre-heating tank, and some sort of pressurized system to spray the oil since its thicker and heavier. Anyone already done this?

Car Heater/ Warmer

Hello I am Melwin from India I want to create a Car Can/ bottle Warmer/ Heater. My Basic Aim is to make hot water for preparing baby formula my baby when I travel with family in my car. This way I can avoid multiple stops for getting hot water. The commercial versions are available in the Market for a minimum of 3000 Rupees. It is very rare to buy in India My plan is to buy a 220 v 1000Watt Heating Element and cut it to suit to 12v When i measured one test setup with such a coil I get around 1.5 Amps per coil. I didnt have a thermometer to test how hot it gets. Since the car Cigarette Lighter supports 10A. I can easily Add 4-6 Coils of the same length in parallel. Also I can add switch to get different temperatures by adding up coil for each switch. 1-2 Coils = Warm. 3-6 coils = Heat. I dont want it to be a huge cooker. It should be able to heat up a glass (200 ml ) of water till 50- 60 degrees C) A higher version can have a Thermostat to cut off things as a safety feature. If this setup succeeds in boiling up water then I can also have my favourite cup nooodles when on long trips with friends I plan to make a small ceramic frame to mount the heating elemmet. On top I will place a Copper plate. Leaving some gap between the Plate and coil. This entire setup will sit in a Tin can of suitable diameter. I need to think about how i get the ceramic frame to Sit inside the can without touching the Metal. To this Metal can i will attach a handle so that it can be handled when hot. My next question. Where do I place it in my car safely. Suggestions/ Concerns/ Comments please Melwin

New water heater

Oh please help me decide( and more importantly convince my buzz word influenced wife), I want to replace my current hot water heater, there's nothing wrong with the current one other than being 18 years old, meaning it's a ticking time bomb waiting to flood my house. So anyways, the local gas concern has partnered with local contracters Tankless install $25 a month of 60 months, minimum spec heater, does not include expensive, required stainless steel venting. $450 rebate Tank heater 40 gallon install $10 a month sixty months, includes venting $350 rebate Now the no brainer, my gas bill is averaged at $41 a month, $30 is actual gas charges, Now, the tankless claims to save "up to 50%" which is marketing speak for "does not save 50%" but let's say it does, I would save $15 a month, the difference between the cost of the tankless versus the tank, so it would be 54 months before I started saving money. And since we plan on "upgrading" to a new house before five years (when I've graduated), I will never see those savings. Guess I really should get the tank heater, what do you think?

Induction heater 2.0

Some might have already tried my first induction heater, which was more a proof of concept than a modern device. Although I like to keep things simple where possible I want to upgrade my heater to a fully electronic version running on mains power. This time the base concept is to use a cheap induction cooktop for the control and power source. After using a few already as a communication device I realised it is a costly way of producing smoke signs but I am getting on the right track with the design now. So my obvious questions are: 1. Did actually anyone ever built my current induction heater and if so, can you provide some nice pics? 2. If you were interested in a hobby induction heater, what would like to do with it?     E.g: Just for curiosity on how it works, heat treatment of punches, chisels and similar,     heat treating knifes or even swords, sheet metal work.... 3. What would like to have included?     E.g: Water cooling for continous use, air cooling (mostly for smaller and quick jobs), exchangable coils,     additional micro controller for temp, water and remote control (foot panel or similar)... 4. Do you require a fully shielded version to avoid interference? 5. If you are based in AU (preferable VIC): Would you be able to donate me faulty (partially or fully) or working induction cooktops,     for example discarded units with broken glass tops?     Would you able to donate me copper tubing OD8mm or less? Leftovers from pluming installations, old LPS systems or similar?     Prefered lenght 1m or longer as the coils need quite a few turns... :(     Each donor will of course be listed in the Instructable unless you prefer to remain unnamed. Let me know what you think because this time I am not just building for myself, this time it is for you!

Miele washing machine - tripping the electricity (RCD)

Hi I have a Miele W5741 washing machine which is three years old. The other day it tripped the electricity (RCD) I found that it would trip the RCD every time regardless of what program I used. After a few trials I have found the following: if I use the machine and select cold water (no heating of water) then it does not trip the electricity (RCD). So my conclusion is that it is the heater that is causing the washer to trip the electricity! What do you think? I opened up the front to locate the heater. However I don’t see how I can remove the heater as I see no screws! I have attached a pic so you can see the front/heater.

Heating for outside battery storage compartment.

I have an idea for a wind powered outside LED light for the family's cabin. It would be on a pole and illuminate the pathway, just like a street light would do. So I wanted to have a battery in a box with my wind turbine charging the battery through the day and night. The problem is, it gets really cold sometimes like -36F / -38C and that would kill the battery. So, I also wanted to include some really small, simple heater inside the box. I'm having problems finding anything on what would be the best way to go about this. Wikipedia says heaters are made by resisting current. Are there special types of resisters you add to your DC current to create heat? Thoughts, suggestions, feedback are all welcome. Thanks.

IGBT ZVS Induction Heater?

Among the many tutorials for building an induction heater out on the internet, there are two primary types. Some heaters use a ZVS circuit, and are quite simple but generally limited to a power of around 1000 watts, not enough to melt most metals. Other heaters use PLL controllers and coupling transformers to add charge the primary coil/capacitor loop, and these can be much more powerful but are significantly more complicated (and expensive) to build. It seems the limiting factor in the power of the ZVS circuits is that they can use only 2 MOSFETs, and each must conduct large amounts of current. However, if these could be replaced with IGBTs, which could conduct far more current, a much more powerful ZVS induction heater could be built. Is there any reason IGBTs couldn't be used for a ZVS heating circuit?

Battery Powered Water Heater

I need some help. Well, I'll be honest, I need a lot of help.  I am trying to heat 1 liter of water running through a small tube that holds 8ml of fluid up by 12C, with a maximum temperature of the heater reaching 60C, and the entire liter needs to be heated within 30 minutes.  In my experiments, the tube holds 8ml of fluid while passing along the 'heater' core, and will pass by the core in a total of 10 seconds. So 8ml heated by 12C in 10 seconds is the limiting factor and multiply that out to cover 30 minutes.  The good news, I have managed to accomplish this feat by wrapping the tube around a curling iron rated at 80W x 110V. End result is 12C rise in output fluid, so I know the theory is completely possible.  However, here's the kicker, the entire system needs to run off of battery power.  So the 2 big questions are: what material should I use as the 'heater core' since I can not use a standard curling iron, and what battery system/configuration should I use (needs to be universal purchase ie, AA, AAA, D, C, 123, 9V, etc) Any help would be greatly appreciated both to my personal safety as I tinker in the garage, and to my wife's sanity as she watches me play with water around plugged in curling irons. :) Thanks in advance. WS.
