Can you run the furnace on 110?
Anyone know if you can run the furnace on 110? I have a 50 to 30 amp converter connected to another that brings it down to standard house plug. My niece and nephew want to sleep in the rig in the driveway but it will be cold. If I could run the furnace in my Georgetown 351DS that would make for a better night for them. Thoughts?

Yes but it also uses propane. You’ll need your converter on or good l/fully charged batteries.
Assuming you Moho is like a trailer.

My gt300 runs the fan from 110 but the heat is propane!

Yup. Need propane. First cold night camping as newbies the Mother in Law came. Being the kind person I was, I let her have the bedroom while DW and I slept on the fold out. We got cold so we turned on the fireplace. Since I was too dumb to know how the furnace worked.
Next morning she mentioned it being cold and I thought "hmmm, maybe I should open the tank......"

Just to clarify. The furnace runs on 12VDC and propane. When plugged in the converter provides 12VDC as does the battery to run the fan and control. Propane provides the heat. You can get a night or two out of battery ( not plugged in to shore power) depending on how much it runs.

I have plenty of propane. I just don’t want to run the generator and the only electric I have is the power from the garage. 15 amp circuit that can go through my normal shore power cord. So consensus is it should work right?

Maybe a little clarity. The furnace is a 12volt furnace (fan/electrical etc.) and uses propane for heat. The furnace will run with or without 110 volts from shore power or generator. With = via the converter/battery. Without = battery only. Propane both ways.

Depending on how cold I believe you can run one ceramic heater on 110.

If you’re connected to a 110 volt plug from the house on 15amp, your system will charge the batteries which is what powers the 12 volt fan of the furnace. Be aware, the propane consumption of the furnace is fairly high.
If you have an electric heater, you could run that and not much else, and not need the furnace IF it won’t get too cold.
If you are ever running your Georgetown off a 15 amp circuit, just think of it as one electrical outlet in your house. How many things, and what power draw could you run off that one outlet without blowing a fuse or tripping a breaker.

Furnace should run ok connected to the outlet from your house. Normally it is the a/c that pulls too much current.
Depending on temperature I would go with the ceramic heater first to save the propane etc.
Just my thoughts though.

Yes you can run the furnace when plugged in to your house current. The converter changes voltage to 12 volt which the furnace operates on along with the propane. Later RJD

Everything electrical on the RV is powered by 110v unless you have a solar panel to charge the batteries - that is considering that 110v charges the batteries. Many items run off of 12v. Even with a 50a which is connected to a 220v service it splits into two 110v only circuits. Everything requires either 110v or 12v. You can run everything in the RV except maybe the A/C with 15a 110v just not everything at one time. Heater no problem.

You guys rock. Thanks for the encouragement and information. I’ve got my kids, niece, nephew, and grandma all out in the RV in the driveway comfy and warm. Thanks again!

The 120 Volts from the shore cord will supply the converter which will in turn provide the 12 Volts the furnace needs.
The short answer is YES, that is just what it is intended to do!

I usually run an electric heater on cold nights, with the propane heater turned on with a low thermostat setting. That way the electric heater does most of the heating but, if it gets too cold, the propane heater will kick in and supplement the electric.

Your first statement in red above, while ultimately correct if you follow the power back, will be confusing to neophytes. 12VDC components are powered by 12VDC, not 110VAC, even though ultimately 110VAC is supplying the 12VDC through the converter.
Be very careful with your second statement in red above. RV's are NOT wired like dryers and if you plug your RV into a 220 VAC dryer-type plug, you'll be very sorry. See here:

Agree with most comments above. We have a combination of portable, 110V floor heater, a built in fireplace, and our propane fired furnace. On cold nights when we have only 15-amp service, we place the floor heater in the bedroom, and set the furnace to about 60 degrees. Keep us warm enough even on really cold nights.

You need a good battery, at least 11.5, volts to operate the propane gas valve. The fan will work off the converter, but not the gas valve.

Are you saying a converter, which will run everything 12 volts in the rv including charging the rv battery (which is 12 volts) will not actuate the 12 volt propane valve?

Pretty sure that's just for 30 amp service.
Unless I'm mistaken, 50 amp RV service is actually 220, but it's not using leg to leg voltage, just leg to ground.
That's why a 30 amp connection is good for 3,600 Watts, while a 50 amp connection is 12,000.
It's the 30 amp connection you need to be careful about.
As I understand it.
Please correct me if I'm wrong.
