    I’m using the product as intended, to heat an engine compartment. My boat is 26’ and the compartment is roughly 8 x 8 x 3. The heater is well built. But my boat is not in the water and I have it at home where the hull is not insulated by the water it would sit in. Thus the heater just can’t keep up with the cold Temperatures. I had to supplement it with another heater, and even then it was on a LOT, IT sucked on the power bill. It probably would be fine for a smaller compartment like a ski boat. Or a boat in the water. UPDATE Over the winter of 2021-22 I kept the boat in the water. As I thought, the heater kept up with the cold just fine with the insulation of the water around the hull. And the electric bill was minimal.

    Works great. I mounted it on a board to keep it from sliding around. Keeps temp in engine compartment at a safe level.

    It comes on at 40 degrees or so, and turns off at 50 or so. Not bad!!

Xtreme Heaters exceeds Coast Guard, ABYC and MILSPEC ratings for heat, cold, moisture and vibration. This has earned our product the trust of our military, where it is installed in special operations vessels, and homeland security vessels across our nation.

We chose modern, efficient, PTC (Positive Temperature Coefficient technology for the core of our heaters. They are self-regulating, offering safety and efficiency gains unmatched by other element heaters.

Each component in our bilge heaters was chosen specifically for the harsh marine environment they live in. A fully anodized aluminum case, a sealed electronics module, marine rated power cord, and our exclusive waterproof fan ensures your heater is the safest and most reliable engine compartment heater, allowing for years of trouble free operation.

Xtreme Heaters are most compact bilge heaters available. They can be mounted in any orientation, including vertically, horizontally or even upside down.
