Will 800w Heater Work In RV Pass-Through Storage Bay To Keep Plumbing And Lithium Batteries Warm?
Published 09/30/2025
Question:
My RV has a large pass-through storage bay with plumbing and lithium batteries. Would the 800W XH27FR be overkill?
asked by: Rachel
Expert Reply:
Not overkill at all, Rachel. That’s exactly where the 800W heater # XH27FR shines - large, shared spaces where you’ve got both plumbing and batteries to protect. It cycles on at 40°F and off at 55°F, so it won’t waste energy heating beyond what’s needed. Just make sure the thermostat on the back has good airflow so it senses correctly.
Is that bay insulated at all, or open to outside temps? That’ll help determine which heater you need.
