Can the Xtreme Heaters Space Heater Run Without Overloading an RV's Electrical System?

Updated 11/14/2026 | Published 07/20/2026

Question:

We take our travel trailer out for a few weekends in late fall, and the mornings can get pretty chilly. I'd like to use a small electric heater instead of running the furnace every time we need a little warmth. I'm looking at the Xtreme Heaters # XH74FR, but I'm wondering how much electricity it uses. Can I run it on the lower setting without putting too much strain on my camper's electrical system? And will it shut itself off if the room gets warm enough?

Hey Randy! Yes, the Xtreme Heaters Electric Space Heater # XH74FR is a great way to warm up your travel trailer without overloading your electrical system, especially on the 750 watt low setting.

That setting draws just 6.25 amps, compared to 12.5 amps on high. On a 30 amp hookup, running it on low leaves you with about 23.75 amps for everything else in your camper, assuming nothing else is drawing power. You'll just want to be mindful of running other big appliances at the same time so you don't trip a breaker.

I'd recommend sticking with the 750 watt setting for everyday warmth and saving the 1,500 watt setting for when you need to warm things up faster and have enough electrical capacity available. It also has a built in thermostat that automatically cycles to maintain your temperature, plus tip over and overheat protection. Just be sure to follow the clearance instructions and avoid leaving it running unattended on high.

Do you usually camp with a 30 amp hookup, or does your trailer have 50 amp service?
