Bread machine
 
Is there anyone who is using a bread machine powered by an inverter?
If so do you know how many amps it uses for one cycle?

I see that they have a rating of about 800 watts, but I am assuming that it is not at that level for the whole cycle and I am looking for an energy budget figure.


Thanks!

Amp hours, not Amps!


You'll see various figures, but Which magazine calculated it as:


Average energy consumption: 0.36 kWh per loaf
Average cycle time: 3 hours 18 minutes


0.36kWh will be a bit over 30 Amp hours pulled from a "12 Volt" system
Peak draw @ 800W will be approaching 70 Amps,

There are different machines. Ours only uses a max of 400 Watts during the baking cycle.

It bakes for one hour, and the heating elements are on about half that time.

We estimate around 20-25 amp hours at 12v for a loaf.

44cruisingcat , do you mind sharing what machine this is?

We used to have a Kenwood. Timing was to run it when the generator was on to charge the batteries and create hot water.

That way you can already recover a fair bit of the power draw.

Still, would be very interesting to hear what machine cruisingcat44 has on board.

Have a friend was has sailed around the world twice. Said the breadmaker was one of the best things on the boat. When I asked him about the breadmaker, he was talking that he could run it without a generator on a Amel 52. Nothing like fresh bread at sea, of course with Irish butter.

Following, just got new breadmaker for our boat.. haven't tried it out yet!

Do 12V breadmakers exist since it seems a very heavy draw on the batteries at mains voltage via an inverter?

To accomplish the same work the draw would be similar.

We use this one...works well on the inverter, ~450W not continuous, ~25AH.

It's an old Breville Baker' Oven. It would be about 20 years old.

Long superseded now.

A couple of years ago it developed a problem where it wasn't baking. The element wasn't heating up. Figured the element had burned out.

New elements weren't available.

We went shopping for a new breadmaker, and found they all required much more power. 800+ watts. And most made smaller loaves.

Anyway I had another look at ours and found no power going to the element, the relay was dodgy. Couldn't source the same relay, but was able to mount a higher rated one on some double sided tape and extended wiring.

Works great again!

Later we found the same breadmaker in a second hand shop, in like new condition. Bought it for $20. So now were covered for the next 20 or so years.

AC/Inverter or 12V, Watts is Watts. You may gain a few percentage by cutting out the inverter losses, but you'd probably need to run new heavy duty cable with big circuit breakers to the galley to handle the peak amperage :(

I simply make bread the old fashioned way...
I made these at home but home or boat it is not difficult...
