Hi,
Unless the outlets are upgraded it is best to keep loads on them to less than 800 to 1000 watts. I have replaced all but two of mine.
When on shore power or running a generator, my favorite electric heaters are 1/2 size oil filled units that draw 464 watts each. I keep one in each corner of the bedroom. I have another "flat panel" oil filled heater for under the dinette.
Solar costs are about $2.00 per watt for parts and materials. It would be best to start another thread about solar systems.
Really the only truly safe catalytic heater is the
Platinum Cat because it is vented. It is also thermostatically controlled so you can keep the RV at a comfortable temperature.
