This heater protects your critical equipment from freezing in your RV or boat. It keeps those large spaces at the right temp with an automatic thermostat. And the quick-release bracket lets you install or remove the heater when the seasons change.
Water lines split open when they freeze. Batteries lose charge faster in the cold. Engines, pumps, and other critical systems might not survive those nights that fall below zero. That's exactly what this heater was built to prevent. At 800 watts, it has the power to keep large RV basements and boat engine compartments above freezing, and the forced-air design pushes heat into the corners where damage usually starts.
This kit includes a quick-release bracket, designed for RVs and boats where seasonal swaps matter. Instead of unbolting the heater in the spring, just pull the latch to release it and stow it away. When cold weather returns, drop it back into the bracket and it secures in place. The anodized aluminum bracket resists corrosion, so it can stay mounted all year without worry. Plus, the heater itself comes with a 15' marine-rated cord with a standard plug attached, so you've got some length to place it where you need (and you don't need to hardwire anything).
You have better things to do than sit there watching a gauge. That's why the thermostat is fixed to switch on at 40ºF and shut down at 55ºF, which is the range that keeps your plumbing, batteries, and tanks safe. It's high enough to stop freeze damage, but it doesn't waste energy making it warmer than you need.
Putting any electrical gear in an enclosed space can make people cautious, especially around fuel. This unit is ignition-protected, which means it's been tested to make sure it won't ignite fuel vapors in engine compartments or bays. For boaters, that's critical for safety when mounting in the bilge. For RV owners, it means reliable operation even in tight spaces where safety standards really matter.

We have used this heater in the underbelly of our RV for the cold winter months and it made a huge difference. I put it under there to keep the pipes from freezing, which it did, but it also made the RV more comfortable which surprised me. Now at first when I looked at it I thought it was just a space heater that had a bit more safety built into it but as it turns out it is a lot more than that. I won't use your typical electric space heater unattended but this is a heater that I will. The way that it heats is different and is even safe to use where there is the possibility of fuel vapors since it was made and designed for boats even when you are not there. The automatic function made it an install it and forget it heater that kept our pipes from freezing at our kitchen sink in extreme cold weather down to 0º F when in the past has frozen up even when running our furnace that is supposed to heat the underbelly of the Rv but did not as effectively as this Xtreme heater. This was a great addition to using our RV in the winter months if not only for the ease of not dealing with frozen pipes while using the RV but also for the floor not being as cold on our feet.
