So my wife hates the thought of being cold.
Here’s my question. Being as it’s getting close to fall. How much will my stove draw my battery down over night? Should I worry about the boat not starting in the morning?
 
I have a Wallas and I have worried about that as well. I haven't run it all night, but I have sat out storms for a day or two and run it quite a bit. I have two interchangeable motor/house batteries on my boat that I can switch between. I always keep one fully charged battery switched off for one reason only, to start the boat motor and the other being the house battery that I use for the Wallas, fans, radios etc. If this battery runs out of juice, I still have a full battery to start the motor. I also have solar panels to help keep the batteries full.

I have found that when I use my Wallas as a heater I prefer to leave it on low with the lid open and use a Camfro fan, which has very low energy draw, which I have mounted above the Wallas to circulate the air. I prefer this as it moves the air around better, helps to keep the windows clear and is quieter than the Wallas fan. I also have a Ecofan that can be set right on the Wallas burner and uses no electricity to operate the fan.
 
Fishcatcher907, unless I misunderstand you, you really should have a distribution cluster to protect your start battery fully.

We run our main engine for a few minutes to assist the Wallas on initial start-up because of the high amperage draw. After that, the Wallas runs all night on just a single 24 Series flooded cell battery and stays above 12 Volts. Gary.

Or just a battery switch that lets you select only one battery into the circuit. I have two batteries, but only run off one. The second is held in reserve.
 
To get even less 12 volt use, we had an Eco fan--which runs from the stove heat--no 12 volt fans at all.

No problem depleting any of the batteries overnight with the Wallas that way. Once the stove has started the draw is very low. (Starting uses a glow plug)

Do you have more than 1 battery?
My wallas uses approx 6ah over night on hi
is plenty warm when ambient is 30F or so.
In winter I use the Planar forced air (13,500 BTU) & at 10F ambient it is 60F to 70F in the cabin.
Good luck!! :thup :beer

Nope mine is stuck in Seward. Not going to drag it home through the FIRE! :beer
 
I bought a portable Mr. Heater propane. No smelly stuff and leaking liquids.
Use mostly for getting dressed etc.

Always warm enough in beeding and a stocking cap which I learned years
ago when did serious backpacking and snow camping.

Keep warm and dry.
 
The Wallas Nordic's (replacement for the old ceramic top stove) circulation fan does not turn off even with the lid up, so no electric savings using an eco fan. The new Nordic works great but I've always been a fan of Wallas stoves. I think the justification for keeping the fan running is to help keep the computer from overheating.

Interesting--do you have one of the Nordic? Not sure I see the logic of running the lid fan to "keep a computer from overheating".

I see that the 85 DT is still available, which can be ordered without a "blower lid". That would be ideal for use of the Eco Fan.

He probably meant circuit board. I have the latest greatest & the fan in the lid runs whenever it's on. :beer

I just put in a new Nordic in early July and, like Jay, have found it to run great. I'm a fan of them too, when they work properly and I have great hopes the new model will be better than the 17-year-old one we scrapped. While talking with Scan Marine about purchasing the Nordic, I was told that the fan now runs all the time to eliminate a troublesome switch which turned it off when the lid was raised. In fact, we had to send our old one in once to get that repaired. Apparently gunk would fall down into the switch and, over time, prevent it from functioning properly. We used to use an Eco Fan as well, but the new Nordic fan is so much quieter than the old one such that it is no longer objectionable.
