Does anyone know of a electric heater with more than 1500 watts?
Several however I do NOT recommend them
Some need 240 volts, no good on a 30 amp circuit
ONE that I know of is 120 but it's been 16 years since I bought it Will try to find it. I still do not recommend it
Multiple 1500 900 watt (1000 or less) is what I recommend without modifying the RV
Why: The type of outlet they use in an RV is rated 15 amps. but not for long. if you hit it with a 12 amp load (1500 watt heater) there is a HIGH chance of failure. Had it happen to me, others have as well. Depending on the failure and how swiftly you detect it your RV may become excessively warm..... as in Here comes the fire department and a total loss (Rv fires are nearly always total loss)
What I did: I installed two 15/20 amp outlets (actually 3) in the RV. These are wired each to a single breaker all its own.. with 12 ga wire, they are fully capable of delivering over 2,000 watts of power Wire is bent around a properly tightened Screw NOT SHOVED INTO A PUNCH DOWN BLOCK, NOT POKED IN A HOLE BUT BENT AROUND A PROPER SCREW.
The Moral of this: Upgrade wiring.
Got to change loads in the washer/dryer will do research and finish when I return.
Ok could not find the item I owned but this is the class. YES these are evaporative coolers:
Ebay
The one I had had a 2,000 watt heater in it. Strange it did NOT blow a 15 amp breaker )(Though I checked it with a Kill-a-Watt and it was drawing 1900 watts or more (The KAW has a 15 amp limit too, I did not test for long)
It also overheated an outlet in the RV. Other than being all white it looked a lot like the one shown in the link, and without trying to see if I still have the owner's manual (not going to do that) I think it was a'Gator' brand. But as I said, been 16 years.
