Would appreciate anyone who has a ceramic or other type portable heater to chime in and tell me what brand they have and if they feel it does a good job heating. My rig is a 32 feet Class C.

thanks in advance,

Jimbo

We have 2 of the small cheaper 1500W ceramic heaters that are common to Walmart etc. They are easy to store and you can run 2 on high (25A for both).

All electric heaters for home use have a maximum output of 1500 watts using electrical resistance for heat. You should be able to run two of them on a 30 A circuit. Sometimes the GRI breakers fight each other.

I like the Little Buddy propane heaters for boon docking. They take the chill off quickly. So does making coffee. I don't run them when sleeping.

use a cheep heater and add one of these remote thermostats will make the temp control very accurate and you can move the thermostat to wherever it works best.

Electric is all about 1500 watts or 5200 BTU and provides the same actual heat.

The question is if you prefer radiant, forced air or convection?

Radiant will reflect the heat direct on you for an instant feeling of warmth.
Forced air will circulate the warmth some or direct it into a cold area.
Convection will provide a steady even heat that seems slower at first but still provides the same BTU.

I use a 1200 watt Delonghi radiator style and it works well for what we need and prefer. I like the lower wattage to run the circuit a bit less than the max as it often runs 24/7.

pretty much the same thing except ours have heating elements and a fan. we use them on coolish nights when the furnace is too much and we want to do without the noise of the heat pumps. a 1500-watt heater at full bore will consume about 12.5-amps at 120-volts.

We use one of the small Walmart ceramic heater with fan. We run it on the lowest setting. It does just fine heating the airstream. It uses about 750 watts and with 30 amp supply we can run other items such as a coffee pot.

If you want quiet, get an oil filled heater. They take up more space but do the job.
Otherwise, get the heater you like. As said, they are all about 1500 watts.
Even the cheap ones.

I have a Vornado and it's about the quietest fan based portable heater around.

I like the ceramic's because they are small.

Portable Electric Space heaters are unique in all of the electric/electronic world as they are 100% efficient. The Reason for this is that all losses become heat so since heat is the desired product they are 100% efficient

OH I know some folks will talk about the fan. but the fiction of moving air creates heat. So that's recovered

or the GLOW from a red hot element.. Absorbed by surfaces it impacts and converted to Heat.

So TECHNICALLY it makes not difference.

Now some.. may do a better job of moving air and that may make you feel more or less comfortable.. but they are all 100% efficent.

And 12.5 amps (1500 watts) is a bit more than I care to put on most RV wiring. THe wires (14ga) are up to it but the "Unibox" or "Quickbox" type outlets.. The connections are often NOT up to double digit current.

Two 750 watt on different circuit breakers.. Should be no problem though .(less than 10 amps per line).
