Yes, but at least it was not wrong.

Sayz who?
The furnace, while having hookups is using 120V that is converted to 12V.
Still the source of power is 120V.

Sayz who? The furnace manual. Look at page 3.

The "source of power" may be 120v, but the furnace only sees 12v of that.

Following your "source of power" rationale, they are actually 12,000v RVs.

12v to furnace from converter. 120v to converter from house breaker panel. 240v to house breaker panel from utility company step down transformer. 12,000v to utility company step down transformer. So, the "source of power" is actually 12,000v.

You can't trace power back that way.

The furnace is 12v. If you don't believe me, hook up a 120v power wire to your furnace and report back what happens.

Yes and when the MH is running down the road the 12v comes from the alternator powered by the main engine.
Still the furnace does not run on gasoline/diesel. Just 12v and propane.

The furnace is using 12v, not 120v. Put a VOM on the furnace, anywhere, and all you will ever see is 12v.

The source of the 12v can be the battery, or the converter, but either way, all the furnace sees or uses is 12v.

Now, the CONVERTER uses 120v.

Sorry double post.

I usually install a toe kick heater, small electric furnace, where ever it is convenient. Works much better than an electric heater taking up floor space and in the way. Also control it with a wall thermostat. Which works much better than the one built in that electric space heater.

If you plan on using 1500 watt heaters it is good to replace the OEM 120 volt outlets with ones that have screw terminals. I've done all of mine except for the gfci in the bathroom.

Those OEM 120 volt outlets are made/rated to not need to be installed in an outlet wall box. While standard home receptacles, most with screws are required to be installed in a box. It is also required that the wires have 6 inches of wire beyond the opening of the box before they are attached to the device, receptacle or switch.

Most RV walls are not deep enough for a receptacle box.

Thanks for all the quick responses. I was trying to avoid space heaters since the one we have does not stop heating even when it reaches the temp we set on the thermostat. I'm going to take it back. It was supposed to be a good one.
