Portable 2kw induction cooker onboard

They also have them at Trago Mills. Probably cheaper than Maplin.

Sounds like a great idea.

If you have two gas burners and one of these, perfect option.

Check your saucepans. If they are magnetic, they are OK on an induction hob.

This looks quite good for the boat (when on the marina). Solves the probelm of only have 2-burners on the cooker also.

I have used the Lidl version for years and they are great. No problem regarding saucepans as Tesco do a range suitable for Induction and if you have some
delax le Cruset they work too. These induction hobs are remarkably effective and efficient.
 
Well I could do with some new saucepans any way as the old ones are a bit scruffy to say the least, the problem is that they are Ali which is nice and light and they stack. However I have just seen these and they seem to have good reviews....

I can't believe I'm on a sailing forum talking about saucepans - this may be the end of the world....

Tesco are half the price.......Get these if you fancy the design....Tesco's just do the job as on the box and do not look special. Just make sure you get the ones with induction symbol on the label.
 
I use one of those when caravanning ... if no mains I run a 2kw Honda genny plugged in to the 'shore socket' .... runs the induction hot plate, usually on reduced power... still plenty hot enough and the heat is instant. If it won't run on the marina supply use it on half power and it'll be ok ... you'll need an induction type frying pan etc but they can be used on other types of cookers as well. Wonderful piece of kit and handy in that I can use it outside - I don't like frying stuff 'indoors' (smelly) and the 'van has an external socket. Much less hassle than a barbie.

Not quite as simple as that. An induction cooker works like a transformer. The coils in the cooker produce a powerful alternating magnetic field. When the base of the saucepan sits on the coil it becomes a one turn coil which has a short circuit. The high current in the saucepan base causes the base to get hot so cooks. Now stainless steel has a relatively high electrical resistance so may not soak up as much power hence heat. Aluminium on the other hand has a very low electrical resistance so may cause problems to the coil current. Iron has a resistance somewhere between.
If utensils have a label regarding induction suitability then go by that. good luck olewill

It's not as simple as that!

The process is induction. The coil beneath the hob induces an electric current in the vessel above. If you want to be pedantic, the coil produces a MAGNETIC field which induces a voltage in anything else around which is magnetic...

So, in pragmatic terms, using a magnet to check the pans will give a very good indication of efficiency when used on an induction hob.

If there isn't anything magnetic on the hob, it won't heat up!

The point of these saucepans isn't so much that they work on space-age hobs, but that they stack inside each other neatly. I've not seen any others that do the same, the nearest you get is camping sets with flimsy folding or removable handles.

But which is the most efficient:
Induction hob
Infa red hob
Electric element ring
Gas ring

Electric hob of some sort really makes sense if you have a genny, Esp. When cruising aboard where there's dozens of different gas fittings. It would cost a fortune to pay a gass bottle deposit in every new country you visited.

No can't agree the material must be electrically conductive not magnetic. Yes it is a magnetic field but an alternating (changing) field which induces current.
A "magnetic " material is one which conducts well a static magnetic field (lines of magnetic force) and may or may not exhibit permanent magnetic field generating properties.
Yes a magnetic conducting material (iron) can enhance the transfer of the field from the primary coil (in the cooker) to the secondary coil (the saucepan bottom) as in a transformer but due to close proximity of primary and secondary coils (the saucepan on the plate) this is not necessary. These currents in the saucepan base can be described as "eddy currents" and are often an unwanted outcome of using iron in a transformer. The fix being to make the iron on thin layers so the natural rust etc between the layers increases resistance.
To prove my point get a piece of copper wire and connect the ends together to make a circle. Drop that onto an induction hob and watch it get hot and probably fuse itself. (the hob may have an interlock so it won't work without a saucepan on it.)
good luck olewill
 
Don't want to be run down by the jousters cantering down the lists BUT

ceramic, aluminium and copper-bottomed pans don't work on induction hobs which surely is what the OP is interested in.
Like me, he accepts the "magic".

We used an induction oven for hardening our strut paint in 1980 and that never, ever touched the sides of the oven. That was about the only part of the line which worked perfectly from the start.

Maybe they do not have proper Induction Hobs in Oz!!! Aluminium certainly DOES NOT WORK!!! Some stainless and Cruset cast iron do work......The magnet test is best Sorry Ol Will :)
 
Well I finally resorted to Wikipediea for answers. Sorry about being pedantic and partially wrong at the same time.
I did not realise that they convert the mains power to Dc then to 25Khertz AC. (big power transistors)
It is all about how far the high frequency magnetic field goes into the saucepan material. Further I think the magnetically permeable material (iron) aids in conducting the filed from the coil into the saucepan base. Wikipediea does not go into this aspect very well.
"The process is induction. The coil beneath the hob induces an electric current in the vessel above. If you want to be pedantic, the coil produces a MAGNETIC field which induces a voltage in anything else around which is magnetic...

Induction has no need of a magnetic (permeable) material to transfer power by magnetic induction. An example being old crystal set coils wound on cardboard with copper wire. A magnetic material however will increase the inductance and may improve transfer of power.
So use of a permanent magnet to test the type of steel is a useful indicator of what saucepan material is suitable but does not relate very much to how the system works. Aluminium does produce the eddy currents but my guess is that the resistance is so low that you get no or little heating. There is apparently on induction cooker which does work on Ali pots. Old speedometers in cars used Ali cup around a rotating magnet. The eddy current providing magnetic drag to indicate speed.
The thing is that a static magnetic field even one produced by DC (electromagnet) doesn't do much except attract another magnet or a magnetically permeable material.
But a magnetic filed that is moving (including being caused by alternating current does incredible things and is ultimately the source of all our mains electricity. (and all radio transmission).
Am I waffling ?yes probably. The bottom line is that some saucepans are suitable for induction cooking but some have too much resistance some too little to match the power transfer from coil to saucepan. good luck olewill
