Heat from heating pipe?

Hi there, is it possible to derivate the heat of the heating pipe of an heater to make a water circle (with a pump) to create ones own heater? Because i feel the heating pipe is extremely hot and it's heat for free, so why not using it? The idea is to build something like a water cooling system for the PC but just without the cooling. Can i wrap a cooper pipe around the heating pipe and let water circle with a pump, so the hot water  passes through the "new heater". I dont know what to use as heating object but there will be a way. Any ideas? Is it even possible? Thank you and sorry for my English :D

Heating box

Hi everybody First of all I want to excuse myself if my english is not perfect. I have a project in mind for a while. I work on construction in Canada and using caulking everyday it get hard to use it during winter if we don't have access to put them inside. So I wanted to build a little box with an heating system that could work on a jobsite generator. I'm thinking about a plywood box nothing fancy as long it work. I though about place 10 ABS/PVC tube that fit perfectly the caulking tube with alots of hole in it so the heat can pass throught it. So the caulking tube can be reached right from the top of the box and due to the hole it won't overheat. So that's the idea so far. What heating system should I use for this system(I don't want to spend alot on money). Maybe I'm thinking about  1 or 2 computer fan to make the heat uniform. I'm thinking about a space where I can put my spare glove to get them dry do you have an idea for that ? And finaly I'm open to any suggestion that can get the box even better ! :) Thanks you

Induction Heating

High frequency induction heating is basically a very efficient way to heat ferrous metals. Induction heating uses an powerful magnetic field to induce currents within the surface of the metal being heated. This means that the coil will not get hot unless the material being heated transfers heat to it. Induction heating is very efficient because no heat is wasted, no heat is wasted because the coil does not produce heat, the heat comes from the workpiece being heated only.

Heating Help!

So my new  major has me in a machine shop that is at my disposal. I have made a few shift knobs but with living in the Northeast it can get cold in the winter months.   I want to heat the knobs, which means finding something that is... - Small enough to fit inside a roughly 1" dia cylinder, depth minimal. - Quickly heat the knob - But not over heat it - Run on a 12v standard supply - Minimal cost I have considered trying to find a "Heating Element" but am unable to find such in a size I need and within a price I want. Maybe a soldering Iron element? I tried "Peltier" but they all are over-sized and debate the conflicting effects of hot and cold. However if figured out I could flip it for summer. I debated running a resistor/other electronic component with just enough power to cause it to heat up, but am worried about it breaking. I wanted to do a high power light bulb, but don't see that working as well as I plan. So I am kinda at a loss...if you have a specific item you can link me to let me see it, or just let me know of an item I can use.

workshop heating ideas.

Hello all, I have a slight problem, while designing my workshop for the winter months, I happened across a monumental problem... how am I going to heat it? As any Canadian reading this will know, our winters are not for the faint of heart (-50 anyone?), the structure I designed has a metal frame, HardiBacker lined inside and out as walls, screwed into the metal poles, fireproof spray foam insulation in between the cement board walls, it has been placed on a gravel surface, and is held to the ground by rebar that is nailed into the ground a few feet, and currently no ventilation. I know it has flaws left right and center, but I'm working with what i have right now, and I've got very little to work with. The structure is quite small 10' x 8' at 640sq. feet. Winter is on its way and I need ideas for heating. I've thought about wood heating but I'll need all the space I can get on the inside. propane heaters are quite expensive, and electric heaters.... well its out in the middle of a field basically. Im looking for something that can heat it up fairly quickly, and is safe, I made it fireproof so i guess a tiger torch isn't out of the question.....  Any suggestions are welcome! Cheers!

Heat powered cooler?

It's rather warm around here. And by "rather warm," I mean it's 105 in the shade, and it's 89 in the house with the swamp at full blast. Does anyone have an idea for powering a cooler with pure heat? Perhaps similar to those lightbulb-looking devices that have an inner bit that spins around when placed in direct sunlight, except that is running a little generator that is then running a computer fan, like the ice box air conditioner spotted on this site. The main thing is I'd like the device to actually be powered by heat. Just for the heck of it. Even if it's just heat mechanically powering something to power a fan that I could have just plugged into the wall. So no solar cells making electricity. I can make parabolic reflectors easily if needed, so don't be afraid to use them. What's the best way you can think of to cool off using heat? "Best" can include inefficient but really awesome, like a fresnel lens pointed at a boiler that is providing steam to run a gigantic fan. I'll go get my goggles, ray gun, and keys to the airship.

So, aim was to make burning juggling balls from chainmail. I used aluminium cos it conducts heat very well, so that ppl hardly would get burned from juggling with these balls. Problem is, that the aluminium became rough and prim and the rings started to split shortly after the ball was being set on fire. I dunno bout forging, but is there a way that i can keep the aluminium rings away from this effect (tempering?)? Is there a way to light up such balls without damaging the rings?

Hamster's heating pad

The winter is on it way. I'm having a hamster, a winter white, but the last winter his caught cold and it cost very much for him to cure him. I don't want my hamster to be sicked any more, so I made a heating pad for him. I used this instructable  https://www.instructables.com/id/DIY-heated-clothing/ and I found it is very well. I use a two - meter 26 - gauge wire, and it only result in a 0.15 ohm resistance. With an 1.5 v voltage, It work well and i need a 10a fuse to protect this circuits:) But last week it overheated and my hamster was burned, quite bad. I'm wondering if there is a solution to this. Would you mind giving me a circuit in which: - there is a thermistor to sense the temperature. - If the temperature is to high (30 celcius degrees ), it gives a relay some voltage and the relay breaks the heater circuits. - And it component should be popular, cause I'm a kid and don't have many time go round n' round to find them. Me and my hamster will very appreciate your kindness. Thanks all.

Calculating heating effect.? Answered

I have been experimenting with making a hot wire foam cutter. This needs to be at least 600 mm wide. I have to hand a PSU capable of providing 14 volts at 2 amps (or slightly below) This is 28 watts. Now the question i would like to calculate the heat the Nichrome wire will reach at any given wattage but have no idea if I can do this. I have several wires that work to different levels, resistance of 30R, 4 R, 137R at the length I am using. Any one any  ideas how to calculate the temp or are there too many variables? So far I have worked empirically and arrived at the conclusion I need either around 18 volts at about 3 amps or I need a wire with a resistance of around 7R to suite the power i have available. I do know that the 20+ watts I am generating is just heating the wire to the melting point of the polystyrene foam. The melting point of the foam is apparently around 220 to 240 deg C (internet) At present it isn't cutting fast enough for my project. which required producing 5 mm thick sheets of foam with a reasonable consistency. i am cutting them from a 50 mm thick 1000mm x 500 mm block.

Microwave stopped heating

Our microwave is about two years old and it stopped heating. The fan ran and the carousel went around, but food did not warm. I took it out of the upper cabinet mount and opened the case. I know about the big capacitor and discharged it with a screwdriver after disconnecting the power. For extra safety I clipped a jumper wire on both terminals. I watched numerous videos at YouTube on troubleshooting a microwave and on testing the various major components at home, but no component showed any signs of failure. Then it began to work again as suddenly as it had stopped working. About ten days later, it stopped heating again. After more testing, still no components showed signs of failure. But, I did squeeze the female spade crimp connectors a little with a pair of pliers before connecting them again so they fit more tightly when reconnected. The microwave has continued to work as it should. My wife remembers a time a few months ago when she ran it and ran it to get something to cook as she wanted it and the microwave stopped because it was overheated. I suspect a connection was weak and heated the metal in the connector enough that it became weak. Later it failed intermittently. We could have called warranty service, but we did not want to wait. Knowing what I know now, I doubt a serviceman would have patiently checked for weak connections, but would probably have simply replaced some parts. When those did not really solve the problem, the microwave would have been condemned and replaced. A replacement oven may not have matched our other appliances as well as our present microwave does. Test procedures for components in a microwave are different than they are for similar components used in (for example) a sound amplifier. This applies especially to the high voltsge diode. Do not connect a voltmeter to the high voltage side of the transformer. When running the microwave, be certain to have a dummy load in the cavity, like a cup of water. A very useful test that checks for power to the transormer primary is to disconnect the primary side transformer connectors and attach aligator clips from a voltmeter to the transformer leads. Then run the microwave for a few seconds and check for a full line voltage reading each time. A clamping ammeter to measure line current helps because the sound with the magnetron working is not too much differnt from the fan and carousel running without the magnetron working, but, it is easy to see the extra needle deflection when the magnetron is also drawing current.What seemed to be an expensive problem had an easy inexpensive solution.

heating coil advice(resistance wire)

Hi, my name is david. im working on a project, for a device that is roughly .25-.5 inches long. im trying to find the right material resistance wire for the application. the components are submerged in coolant to maintain a low temperature. i wish to have a resistance wire of some kind wrapped around the components to heat them to about 90 degrees as quickly as a possibly can, for only a brief time(fractions of a second) i am using a variable power supply to determine my power needs. im hoping to be able to send a quick "signal" through the resistance wire, and use heat as a sort of input/output system. the internal components will melt at temperatures above 100 degrees.  so regulating the temperatures is key.  now obviously since they will be submerged in coolant, the resistance wire will need to heat to higher temperatures in order to heat the other components. ive been doing some research on nichrome and kanthal wire. but from what ive seen so far, it almost heats up to quickly, to higher temperatures than i require. it is hard for me to do the calculations, since i dont know how many watts/amps etc i will be using.  so to recap: temperature required about 90 degrees. (as quickly as possible, "flash heating" to 90degrees would be great) length is .25-.5 inch (the size will actualy be determined by the resistance wire i would prefer it to be as small as possible but i could make the module larger if i have to) variable power supply to determine my power needs(preferably the lowest possible power usage to conserve battery power) any suggestions on an appropriate material would be appreciated. i dont mind testing out different materials. i just dont want to spend thousands of dollars buying a little bit of everything and testing each one out one at a time. >< some experiments have suggesting silver coated nylon, but requires 20watts and a pretty sizable heating time. the heating coil will most likely have direct contact with the components, unless it is required to provide space between the coil and the components to heat it appropriately. i would prefer direct contact though to make the modules as compact as possible. currently the coolant is being pumped continuously through the whole system, but ive been working on plans for a valve to interupt the flow of the coolant during cycles where the coil is activated, if the need arises to keep the coolant from preventing the resistance wire from heating up appropriately.

I have a few small projects in mind that have come to a standstill because I lack one piece.  What I would like to get my hands on are small heating elements capable of temps between 80-400 degrees F that are as accurate as possible, preferably within two degrees. I have tried researching this online, but after browsing for an hour I was unable to come up with anything that would suit my needs.  I have considered buying a digital heat gun, but I can't find reliable info on how accurate they are and what range they have. I don't want anyone to think I am trying to build bombs or anything like that so here are two of the applications I had in mind. The first is my truck.  From what I understand those 'super chips' people buy to override the computer and add power typically change the air/fuel ratio.  That can be done by manipulating the perceived temperature of the air entering the intake.  My idea is to create a small housing around the airbox thermostat and digitally manipulate the termp in order to manipulate the A/F ratio.  My second idea is...well...best not discussed openly, but I assure you it has nothing to do with the creation of weapons of any kind.
