Induction hob on board

[ianpowolny]

I posted this on our Facebook page and it seems people like the post so for those who don’t / won’t use F/B:

A long time ago a sailing friend suggested we purchase an induction hob. This time, when at home, we bought a hob for about £80. I made a plywood base for the hob to sit on the gas cooker. I had to make a cardboard template get all the holes in the correct position. It all fits very nicely. We are using the marina hook up electricity which is included in our moor rate. With Camping Gaz cylinders at over €20 a pop it won’t be long before we break even on the cost of the hob.

what sort of amp draw for one of those things?

You might want to check that running both at full power is not going to overload your shore power circuits.

Here Ikea sells portable single induction hob and it draws 8.5a. In Aus a single plug is rated at 10amp and we have 15amp plugs that need a special wall plug.

I see you are using a UK/Euro converter, you might want to check what it's rated for also.


Great idea, but you better check your safety. Maybe the worst that will happen will be that you will trip your RCD, but I don't know as I'm not a sparky (Aussie for Electrician)

I see the hob you have is rated 2800w so it will draw 12.1 amp. It looks like UK/Euro adaptor plugs are rated 10amp.

I also see that UK BS 1363 plugs can contain 13A fuses, which is perfect for your hob with a UK domestic wall socket.

I now see that Euro type E & F sockets/plugs are rated for 16A, so the Hob might be fine EXCEPT for the UK/Euro adaptor plug which could be your weak link.

You should see if you can find a higher rated adaptor (if they exist) or change the plug over.

Hoppy,

I think this marina supplies 3.5kw and I know it might be less in other marinas. We’ll see what we get elsewhere. The hob is rated at 12 amp.

I just checked with both rings at full power there’s no drop out. I just changed the hook up cable to a 16amp x 2.5mm2 cable. The old one was 10 years old and had a nick in it. If I’d cut it it would have been to short in a single run.

The AA adaptors are rated at 13 amp but also have EU plugs rated at 16 amp.

So far all good. Thanks for your safety thoughts.

I have used an old style electric hob for about 7 years now and it has saved a lot of gas when shore power is available. I managed to find some cheap laminated board in a Spanish DIY shop and cut it to size. It sits on the cooker and just inside the heat shield in use and under the cooker for storage.

My wife would MUCH prefer an induction unit as she has one at home. Unfortunately, I've never managed to find one small enough to fit between the bulkhead and the fridge lid. Everything I've seen will just overlap the fridge lid by a cm or so, very annoying.

Your picture shows holes underneath the induction hob. I hadn't thought about it but it makes sense as there's probably fan cooling for the unit. I'll keep on searching for a twin hob unit narrower than 575mm.

Have you thought of going port and starboard rather than forward and aft as we have our hob. This one is 28cm x 52cm.

Thanks Ian. I had looked at various options before, 2 x single or with controls at the side. I couldn't find anything suitable and wasn't surprised at the time. It seemed reasonable that two individual units would be larger than one double an one with controls at the side would be wider.

However, the one in your link manages to be narrower and should work. The technical details says it uses Gas as fuel, amazing. I wonder how they managed to miss that error. I looked at another similar unit and it claimed to work with all pans (cast iron, stainless steel and alloy). It also had a diagram showing that 150mm clearance was needed on either side. I spotted a similar non-induction hob using the same installation diagram. I suspect they cribbed a lot of the details on that induction hob.

Looks very promising and I'll do a little more digging on the specification, position of fans and so forth. It might even be small enough to fit in our wheelie bag and would solve the problem of getting it in Greece.


EDIT:
I've found the same item through Appliances Direct for about £90 and downloaded installation details. The side clearance isn't a problem as it is only 50mm and I'm fitting it sideways. The clearance is therefore at the front and back where I have plenty of room. It mentions a heat barrier underneath as the temp. exceeds 95C. That shouldn't be a problem either as the profile has a step underneath and could well simply sit on the existing cooker top. I can fit retraining bars to front ant back and clip them to the existing heat shield. A bit overkill as it won't be used when sailing or motoring.
