Induction/Expanded Electric vs Propane What Would You Do?

[Chotu]

I should also add we run the generator for the electric oven currently on the boat in question.

Either you've a boat that supports **lots** of panels, or you're just timeshifting generation of very regular ICE power.

Or maybe timing the cooking for "free excess" production, which would probably be the cleverest load dump I've come across yet, Instant Pot, thermos cooking, opportunistic flatbreads, hmm now I'm hungry 8-)

Bingo. It's using excess solar. We don't cook at night, so we won't use batteries to cook, other than to take up some slack when on the highest setting.

When it comes to baking, I chose to go electric/generator already with that since it's not used all that often compared to the cooktop.

And yes, I can support 4kw of solar easily with room to spare, but I don't think I need that.

Well, my stomach is certainly also happy with lunch time and battery + solar should bring in enough to support and recharge if required.

But watch out afternoon/evening. You could also get hit by the AirCon

Very true. All HVAC is off the genetator. It takes a LOT of power to cool a 50’x25’ box with windows everywhere. Solar doesn’t have a prayer for that. It’s eben a stretch for the 5kw generator.

On hot days cooking, I'm assuming we'll cook from the generator anyway since it'll be running for air conditioning.

Not that much, it may take 1800W for a few minutes to get up to a rolling boil, but once you are there it takes a lot less for the rest of that 20 minutes to keep the pasta cooking, so would probably draw 800W for about 5 minutes in total (i.e. more like 6 - 7 Ah).

How do You bake bread ?

Either no-knead bread in a Dutch oven in the oven, or a Zojirushi bread maker

Good to know! Seems more feasible the more real world data I'm getting

Zojirushi bread maker.... AWESOME little machine

Hahaha, I think once You get used to it You can´t live without it anymore. A whole part of the menu will disappear

But look at >Basic Bread Setting ...cycle = min 3-4 hours @ 450 W
and what to do when this little helper is in a bad mood ??
Who is going to repair it ?

Some extra pounds but Dutch Oven seems more practical on the boat

A bread maker uses almost no energy at all. During dough rising it uses zero Watts.

That's just the thing with buying items that are inexpensive and available in stores everywhere. When it breaks, you don't need a "marine" breadmaker technician to come and fix it at $120/hr. You don't need to wait on parts that cost $800. You don't need to spend your weekend slaving away on it. You just go get a new breadmaker. After about 30 years on the water, I've come to realize this is the way to do it, where safe and prudent.

All the sources I've seen say around 3-400 Wh for a loaf. (around 30Ah @ 12V ?)

To be honest I don´t know. Just copied the cycle times of the owners manual of their smallest machine for size 1 Lbs max

Leaves to hope it will happen at the end of a long passage and not at the beginning.
Hahaha, is that what You are trying to say ?
Never used one of those little slaves but reading in the manual in the kitchen comes next in line with auto pilot.

Well, exotic question.... haw fast can induction heating with a 1 top burner heat a bigger Qty of water ... let´s say 5 gal ?

I agree with S/VJedi a bread-maker uses very little power. A small amount of power for 20 minutes to mix the ingredients into a ball Thirty minutes later 15 seconds of kneading and then an hour later baking for the last hour at 470 watts.
