The thought the motor boat forum is the right place for this even though I have a sailing boat....
I just wondered if anyone has built in one of the modern combi microwave convection ovens, sometimes called speed ovens.
How energy efficient are they ....do they need much airspace around them when built in.
How do you find them?
thanks John

Quite good, but only quite, and they are usually 600mm wide and have almost the same space requirement as a proper Miele or Siemens compact combi oven so you might as well get one of those if you're doing the job anyway

They don't need much air space around them. 50mm top and bottom approx. The Miele website gives all the fitting dimensions of their units

Sorry if telling you how to suck eggs but the decent ones are 3.5kw/13-15 amps kinda thing so you need a genset that can cope. Or shorepower use only

Well worth fitting, as you can do proper meals with this kind of kit

Assuming you mean the domestic type ones, then as JFM says, they need up to 3.5kw, but fitting is pretty simple as the air flow is built into the frame of the oven, with the exception of often having an additional grill-vent installed at the top. Look up any of the German brands and they'll have the dimensions, but £1k is quite easy to spend. There is alot of cooling air going about, especially after use, and its pretty noisy.
Lower down the food chain are various combi options, Panasonic making alot of them, from conventional grills to (halogen?) grills. These arent that great.. might brown a topping for you but nothing like a full jobbie, but a stand alone can be fitted for £100, as opposed to the fully integrated ones.
Basically, a decent microwave does alot a conventional oven does, and the cheaper grills dont add much IMHO. And a stand alone one with grill will need some additional fan somewhere in the installation as they dont have cooling fans for the housing to the extent the integrated ones do, and alot of heat is generated by the grill unit.
 
Thanks for the replies so far.... 3.5kw is a bit much for me.... I just looked at the specs for the LG solardom which is 2.7kw which is ok for me as my inverter is 2.5kw.

Not my area at all, but I think the start up demand can be in excess of the rated amount.. maybe you want to check that. Or maybe I am talking ****.
 
We have one as OME and its fab - use it all the time in all modes. What is interesting is in conventional mode (fan) it draws amps at start up and then kicks in / out during the cooking process - once its warm its 'off' more than 'on' so not that power hungary. Microwave seems to draw 100% over albeit shorter time - as others say combi mode goes nice jackets, conventional great fries.
 
We have a combination oven on our boat. Its a Panasonic like the model NN-CT579SBPQ which is currently less than £200, a lot less than when they first became available.

It has the convection fan oven +micro + grill. Different current consumptions with different uses. Max wattage is listed as 2385W although the individual bits add up to more than 3kW so I guess this is regulated.

Our most useful setting is convection+micro when it does amazing roasts and hotpots etc as well as great baked pots. Very nice recipe book came with it.

You can get bigger capacities but this went straight into the boat to replace a standard microwave oven and works just fine.

When using convection it does get hot so plenty of space round is required but I guess that will be the same with all makes. Normal micro is much cooler.

Hope this helps

That's ~100amps if you are 24v, ~200 amps if you are 12v. You'll need VERY big batteries unless you're cooking a very tiny chicken :D

It has to be said, unless your saily boat has a generator (a good sized one too), or the keel has 8 tons of batteries in it, the only place you'll use a combi oven on your boat will be in the marina, connected to shore power.

FYI, microwave ovens do have a bigger current draw on startup than in use.
 
Thanks for all the replies, the reason I asked is because as the years go by oven and hobs get even more efficient... so I try to optimise my cooking systems and I figured that the latest combi ovens are even better now than my oldish microwave/grill.

Hey...just a thought... i said I have a 2.5kw inverter.... so I think we can assume I have a bit of experience how dim the lights go in the middle of cooking a small chicken.
