Description
When the temperature drops, an unheated compartment is where the trouble starts: frozen plumbing, dead batteries, cracked fittings. The Xtreme Heaters Large 800W keeps that enclosed space above freezing so your rig comes through winter intact.
Built for boats up to 35 feet and the tight bays under a skirted RV, the 800W delivers true forced-air heat that circulates evenly instead of baking one hot spot. An automatic thermostat does the thinking for you: it switches on at 40°F and off at 55°F, so it only runs when it needs to.
The design is failsafe by construction. It cannot overheat, the element is self-regulating, and the whole assembly is anodized inside and out to shrug off salt, damp, and corrosion. It is IP68 rated, tested to U.S. Coast Guard ignition-protection standards, and MIL-SPEC tested for vibration, humidity, and temperature extremes. Installation is plug and play: a pre-wired 15 foot marine-rated cord with a standard 110V three-prong plug means you mount it, plug it in, and walk away.
Pair it with EZ-Snap skirting and the two do one job together. The skirting seals the cold out, the heater holds the warmth in, and your propane use drops.
