Features to know about

Stop Freeze Damage Before It Starts

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 400 watts, it has the power to keep small RV basements and boat compartments above freezing, and the forced-air design pushes heat into the corners where damage usually starts.

Added Flexibility with the Quick-Release Bracket

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).

Thermostat Automatically Turns On and Off

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.

Ignition Protection Keeps You Safe

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.

Notes:

  • If your boat is docked on a lift or trailer, you may need to consider increasing the wattage of the heater up one level to compensate for heat loss. Make sure to cover the fresh air vents to prevent air from escaping and the cold from coming in, resulting in a more efficient heater and saving you money.
  • Because boats vary in materials, insulation, and design, it's essential to carefully assess your specific needs and climate to determine the most suitable heater. In some cases, depending on the size and configuration of your boat, more than one heater may be necessary to ensure adequate protection.

by:

I like that the Xtreme Heaters 400-watt RV and Boat Heater with Quick-Release Bracket (XH67FR) is small enough for tight compartments but still has features that make it practical year after year. The quick-release bracket is the first thing that stands out it’s great for folks who pull their heater out in the spring and drop it back in when cold weather returns. Instead of unbolting anything, you just slide and latch it into place, which makes seasonal storage a whole lot easier. Once it’s mounted, the automatic thermostat takes care of cycling the heater so you don’t have to babysit it, and the forced-air fan helps push warm air into the corners where freeze damage usually happens. The body is anodized and ignition-protected, so it’s safe in engine compartments and durable enough for damp spaces. If you’re dealing with a larger boat or RV bay, you’ll want to step up to a higher wattage model, but for smaller boats and compact RV storage areas, this heater with the quick-release bracket is a simple, reliable solution.

  • Do I Need Individual Bilge Heaters For 24' Yamaha Crosswave Jet Skis In Covered Lift During Winter?
    Troy, each jet ski really needs its own protection. The 400W # XH67FR is usually enough for a single PWC. The 600W # XH77FR could cover a larger bilge, but with two separate skis you’d want one heater per hull. Covers will help retain warmth, but I’d still go with individual 400w heaters. Do your skis have shore power at the dock, or do you bring them home to plug in?

  • Which Heater Is Best To Keep Bilge From Freezing During Winter On 34 Foot Carver Cruiser Boat
    Derek, the 800W # XH27FR is designed for boats up to 35’, but in a tight compartment with multiple engines and pumps, many owners prefer using two smaller heaters like a pair of 400W # XH67FR or 600W # XH77FR on opposite sides. That creates a circular airflow pattern and ensures no cold pockets. How is your bilge laid out - wide and open, or divided up around the engines?

  • Will 400w or 600w Heater Work For Winter Storage In 25 Foot Bayliner Boat?
    Paul, that’s right in the middle sizing-wise. The 400W # XH67FR is rated for boats up to 24’, while the 600W # XH77FR is made for boats up to 28’. Since you’re at 25’, I’d lean toward the 600W for extra margin, especially if you’re storing on a lift or in harsher winters. If the boat sits in the water in a mild climate, the 400W could be fine. Do you normally see single-digit temps where you keep your Bayliner?

  • Can Xtreme Heaters For RV Basement And Boat Bilge Be HardWired Into Breaker Panel Instead Of Outlet?
    You can, Daniel. The 400w heater # XH67FR comes with a 15’ marine-rated cord, but many RV and boat owners hardwire them into a dedicated breaker. If you’re comfortable with electrical work, you can do it, though I’d recommend a licensed RV or marine electrician so it’s done to code. Xtreme doesn’t void the warranty if you cut the plug off. This kit also comes with a quick release mounting bracket which is super nice. What is your reasoning for wanting to hardwire instead of plugging it in?

  • Can Xtreme Boat Bilge And RV Basement Heater Set On Floor On Does It Need To Be Mounted / Bolted ?
    Alex, you can set it on the bilge floor if you want, but mounting is safer. The 400w heater # XH67FR comes with a quick-release bracket, so you can mount it securely on the floor, wall, or ceiling and still remove it easily for service. If you do just set it down, make sure it won’t tip into any standing water or interfere with moving parts. The bracket only takes a couple screws, and it really helps direct airflow where you need it. Want me to show you a diagram of how the bracket clips in?

  • Is It Safe To Leave Xtreme 400w Heater Plugged In All Winter In Boat or RV?
    Greg, you’re good there. The Xtreme heaters like 400w # XH67FR are designed for unattended, automatic operation. Once it’s plugged in, it’ll cycle on and off as needed. That said, it’s always wise to check in after power outages or storms - a tripped breaker could shut the unit down without you realizing it. I usually recommend testing the heater at the start of the cold season with freeze spray or by putting it in a cold space to make sure it kicks on. When installed correctly, this will...

  • Can Xtreme RV Basement and Boat Bilge Heater Be Installed Upside Down Or Sideways In Compartment?
    Absolutely, Chera. One of the nice design features of these Xtreme heaters like 400w # XH67FR is that they can be mounted in any orientation - sideways, upside down, or flat - and the forced-air fan still circulates heat effectively. Just be sure the thermostat on the back has access to the same air it’s heating, so it knows when to cycle off at 55°F. I’d avoid putting it too close to battery chargers or in a spot where it could get splashed. Are you trying to protect just your batteries,...

  • How To Keep Boat Bilge From Freezing During Winter On 2022 Sea Ray Runabout
    Mark, the 400w heater # XH67FR is sized right for smaller single-engine boats like your Sea Ray, especially when it’s stored in the water. But since you’re keeping it on a trailer, the bilge will get colder and lose heat faster than a boat in the slip. In that case, Xtreme actually recommends either moving up a size to the 600W # XH77FR or using two of the 400W units for extra coverage. If you stick with the 400W, I’d at least cover your vents and outdrive to reduce heat loss. Do you...

  • Which Heater Is Best For Winter Storage Of 30 Foot Cruiser Boat On Lift?
    John, lift-stored boats lose heat faster than those in the water, so you’re smart to ask. The 800W # XH27FR is the recommended size for 30–35’ boats, but in lift storage, many owners either add a second 400W # XH67FR or 600W # XH77FR heater or go with two 800W units if the compartment is large. You’ll also help it perform by covering vents and outdrives to cut cold airflow. Do you have access to shore power on your lift, or do you rely on a portable generator?

  • Can A Space Heater Protect My RV Fresh And Gray Water Tanks ?
    Jennifer, the Xtreme heaters are built to protect enclosed compartments like pump bays, plumbing manifolds, and battery spaces -not the tanks themselves if they’re hanging exposed under the RV. Many travel trailers and fifth wheels have black and gray tanks suspended outside, and in that case you’d need tank heating pads instead of a compartment heater. If your rig has an enclosed underbelly where all the tanks and plumbing are together in one large cavity, then the 800W # XH27FR would...

  • How Many Amps Does 400W Xtreme RV Boat Heater Draw From 12V Battery Bank?
    Good question, Linda. The Xtreme Heaters RV Basement and Boat Bilge Heater with Quick-Release Bracket 400 Watts # XH67FR pulls about 5.2 amps when running, with a brief startup inrush around 8 amps for a second or two. That’s well within what a 15A RV or dockside breaker can handle. Just avoid running it on the same circuit as heavy-draw items like space heaters or microwaves. Do you plan to run it off shore power only, or are you considering a generator backup?
