Hi ! Welcome to IRV2! We're sure glad you joined the gang!

The maximum wattage on any electric heater is 1500 watts. That's about 12.5 amps, which is safe to use on any AC outlet as long as there's nothing else on the circuit pulling any significant current. All AC outlets are wired for a minimum of 15 amps, some are 20 amps.

Good luck, happy trails, and God bless!

1500 watt heater will cook many not so great outlets over time.
A good 20A new outlet would help or TFCI outlet will trip if it gets too hot. If you plan to use electric space heat please get some quality home units.

Thank you for the info, when you say a lot on the circuit...what constitutes a lot? I mostly have phone chargers plugged in, a small de-humidifier etc...are all the outlets in the coach on one circuit? i am sure this sounds dumb to ask lol, but i am completely new at all this ...thanks again

Thank you, i will look into that outlet, is this something Home Depot would sell? Also, can you recommend a good quality low watt heater? My coach is extremely small 23ft including tongue

Look over your breaker box.
Each breaker should be marked.
I would want a 20 amp with nothing elso on the breaker.
You should talk to a technician or electrician familiar with your rv.

Home Depot has 20A outlets, but you should NEVER just replace a 15A outlet with a 20A one before verifying the wires are sized correctly. Good thing is you shouldn't need the dehumidifier during the winter.
Still looking for the ideal Newmar DP!

I'm a big fan of the oil-filled radiator type electric heaters (we have two at home and one in the RV). The low profile ones like take up less space in a smaller RV although the larger ones may be more efficient:


This one has two power level switches, 500w and 700w, which gives you three choices of settings, 500w, 700w or 1200w. The larger ones generally run at 700w/800w/1500w depending on the switch settings. This type of heater may take longer to heat things up than other heaters but are completely noiseless with no red-hot heating elements. We usually take the chill off with our rig's built-in propane heater and then let the electric heater take over for the long haul.

Since most all RVs use the daisy chain method of wiring that means one 1500 watt heater plus a hair dryer will likely blow a circuit breaker. A couple of space heaters plus the water heater running on electricity and the refer on electric you could be out of power if your RV is a 30A unit. If its a 50A unit you still could run short of power pretty fast.
BTY even if you did use two 1500 watt electric heaters your going to burn a LOT of propane a day to keep inside temps above 50 degrees. RVs are simply not i sulated worth a darn. No matter how much you spend on one they are just not energy efficient. You will be better off to either trqvel to a warmer climate or rent an apartment.

In my experience, a dehumidifier is needed more in a small trailer during the winter than in the summer.

Are you planning to stay in Michigan through the winter? If so, you need to think about some other things other than a space heater. Insulation, single pane windows?, keeping snow off your roof, water pipes freezing, skirting around the RV, and if using your furnace, also, you'll need a BIG propane tank.

Let's address your original question. RV wiring is not the same as your house. The outlets are designed differently. The wire is hooked to the outlet in such a way that heat build up is more likely in an RV outlet. You can run 1500 watts for a short while. Hair dryer and such. Long term high watt use should be discouraged because heat builds up with time and can cause problems. There are several electric heaters on the market that have dual watt heating elements, just like your three way light bulb. Ours has a 600, 900 and both together at 1500. I'll use the 600 or 900 side on any of the RV outlets. I also added a separate 20 amp outlet that has its own cord and plugs into the 20 amp pedestal outlet. I'll run the 1500 watt setting on that outlet.

Some folks have run 1500 watts on their RV for years without a problem. You may do that as well but I prefer not to. Just because you can doesn't mean you should. RV fires are fast and often fatal. I don't want to try to bail out of that little window in the middle of the night.

Thank you for all the advice, i am staying in Michigan through the winter...I have wrapped the bottoms of my coach in 2 in R-10 foam board insulation, bought a slide cover, and had vent covers installed. I just purchased vent pillows for inside. The coach is a 2020 extended season with underbelly covered, insulated and heated. Hoping with the foam board insulation as skirting it will help....I wrapped my low point drain and fresh water drain and overflow values in foam and insulated tape. I am looking into getting a 100gallon propane tank today actually and have insulated the doors on my passthrough storage with foam board as well. I have all but my kitchen window with plastic on them... Left my kitchen window with access to open for cooking etc...hoping i am on the right road to surviving the winter... Any other tips to help????
