6 Best 1500 Watt Space Heater For RV in 2026: A Practical RV Guide
Six 1500 watt electric space heaters compared for RV use by thermostat, tip-over protection, ETL listing, size and noise, with load notes.
By Hardcastle's RV Editors
10 min read6 products evaluated
A 1500 watt electric heater draws about 12.5 amps at 120 volts, which is a large share of a 30 amp RV circuit. That means it competes with the air conditioner, microwave and water heater for the same capacity.
The six picks are all plug-in electric heaters, and none is a combustion heater or a small plug-in heater for a 12 volt outlet. They are ranked on thermostat control, safety features and size, since a heater in a small RV needs to be compact and attended.

What Matters Before You Choose a 1500 Watt Space Heater For RV
Key buying criteria so you get the right fit the first time.
Circuit load
A 1500 watt heater draws about 12.5 amps at 120 volts. On a 30 amp RV circuit, that leaves little room for the microwave or air conditioner. Add up the loads before you run it.
Thermostat control
A thermostat cycles the heater to hold temperature, which saves power. Fanspex and FOHERE list one. Look for a knob or temperature range.
Tip-over and overheat protection
These shut the heater down if it falls or overheats, which matters in a moving vehicle at rest. All six list them. Check the safety notes.
ETL listing
ETL is a safety testing mark. Fanspex, FOHERE and Oprunsy state it. Look for the mark on the listing and the unit.
Size and placement
A compact heater fits on the floor of a small RV, but it needs clear space around it. Blocked airflow around the unit raises the risk of overheating. Check the dimensions and the clearances in the manual.
Attended use
Run a heater only when you are present and awake, and never as a sleeping heater with blocked airflow. Most heater manuals warn against unattended use. Check the manual for those warnings.

For 30 Amp RVs Specifically
- Look for
- A low-power setting and a thermostat, as on Oprunsy 1500W.
- In this comparison
- Oprunsy 1500W has a 900 watt setting. No electric heater should replace a proper RV heating system, and none of these runs from a 12 volt outlet.
When to Spend More
- Spend more if
- Spend more on Fanspex 1500W or FOHERE 1500W if you want ETL listing and thermostat control.
- Save if
- Save with Oprunsy 1500W if you want a low-cost heater with a low setting.
Before You Bring One Home
Can I run a 1500 watt heater on 30 amp?
Yes, but it draws about 12.5 amps, so other loads must stay low. Oprunsy 1500W has a 900 watt setting.
What is the common space heater mistake?
Plugging into an extension cord. Use a heavy-duty cord or plug directly.
Is Fanspex worth more than Oprunsy?
If you want a thermostat knob, yes. Oprunsy 1500W costs less with a low setting.
How do I place it?
Put it on a flat, hard floor with clear space around it. Keep fabric away.
Can a small plug-in heater heat an RV?
No. A small 12 volt plug-in heater cannot heat a cabin. These 1500 watt electric models need a 120 volt outlet.
