It seems sensible that when you are in a Marina with free electricity you should use a microwave oven rather than your gas if you have one aboard.
Mrs Nostro has been looking around and decided that the combination microwave/ grill / convection ovens that are around are good value and she could cook most things in them.
My concern is the power/ amps they use.
I don't want to be the one continually tripping the pontoon or marinas power supply so what should I be looking for and does anyone else use one?
Thanks
 
get a combo.
the grills are not that good imho but get one with pre set baked spud/ pizza ect, they work well.
we installed a micro + grill about 8 yrs ago as we were going to be in marinas most nights on our holiday. that was a good call, cooking foc :D
 
A lot of new boats have them built in now I think, I miss having an oven of any description & not really room for one, either gas or microwave. Pressure cooker is very useful though, you got one of those?
 
Jut wondered what power/ amp stickers on a oven I need to be looking at so it will still work on a boat.
Electricity is not my strong subject, then again neither are engines and sailing.. I can tap computer keys though!!
 
Hi how are you getting on. We last met in la rochelle and are now in Mallorca so you may run into us again!

Back to the topic. We have a sharp combi oven micro on our targa 40. I draws about 8-10 amps at full chat. Most marine shore power is ok with this. Spain is mostly 16 amps. La rochelle was 6 but even then they did not pop until about 11 amps.

The oven works well - somewhat to my surprise!

There should be a plate which gives the power max consumption . As a rough indication however our basic 800 watt microwave consumes 1420 watts (6 amps at 240volts.)

Thank you for that, hope the daughter is still dragging you around.
Well you got there quicker than we did but that is no surprise.
Put a beer in the fridge for next year.. looking forward to it

800 watts is the microwave power rating.

1420 watts is the power it pulls from the mains.......


Like for example your 25 watt VHF radio actually draws 5 or 6 amps ... 60 or 70 watts of power ... from the 12 volt supply

I have just got an electric oven(no microwave) Can cook all the things a microwave can and heats up the boat/camper too. (maybe not a good idea where you are)

Can't see any problem - go for it.

Errrr....for 'free' please read...."included in the price!"

Maybe they charge for the 'leccy and the berth is 'free'?.....

Don't think so.
 
I have a Panasonic combination microwave / grill / oven. Not on the boat but it is a brilliant item. Microwave is 1000 watt and the specification says that at 220V it draws 5.9 amps for the microwave and 6.9 amps for oven or grill. At 240V the current draw is slightly lower.

I spent a winter in Marans - the frequent power-outs were invariably caused by more than one person attempting to use their electric cooker.

You'll find that on a 16 amp outlet your cook will have to be very circumspect and eschew use of the fan-oven, especially as most pontoon end-berths are down to about 215 volts.

You can overcome this problem with a charger/inverter with power boost - allows you to set a precise limit of current which your boat is allowed to draw from shore power, and will make up the difference with inverted power from your batts. This will prevent your tripping breakers. Of course, your short term average power draw needs to be less than what is supplied, or you will flatten your batts, but you can usually get 3kW or more even out of a carp French shore power connection (unless you get one of those 6 amp ones like we had in St. Malo once), so you should be ok with a convection oven.

What about running the microwave and convection oven at the same time as some of these ovens do.. sounds like an awful big draw.
 
combi oven

Installed one last year, no probs at all when on shorepower, but doesn't like the generator output (2.4kw) because it's not pure. Am tempted to get a 2kw invertor.
When fitting oven be aware they need alot of room behind and on top to disapate heat.
