Xtreme Heaters Boat Engine Compartment Heater | Large 800w Bilge Heater - For Boats Up To 35 | Boat Heater, Well House Heater, Camper/RV Heater, & Marine Heater - Safe Self Regulating Bilge Heater

Product has worked as expected. It has kept the engine area between 42-55 degrees with outside temps in the 20s Update 2nd winter season. Temps got to 8 degrees outside. Engine area of the boat never dropped below 40° Great little heater.

Makes me more comfortable and the winter knowing that my engine room is protected it from freezing. It appears as though the colder it gets outside but warmer this heater warms up that space. I love this product. 3300 Tiara Yacht owner.

I have mounted it on the underside of the engine space hatch cover. I tested it as the instructions say by putting it in my freezer for an hour, then taking it out and plugging it in. It turned on as it should then after a warming up period turned off. It ran pretty quietly with a gentle heated air flow in a way I don’t think will blow a breaker. Be sure to close off any vents or other ways outside air can get in and warm air out.

Very happy with the product and the tech support. Simple to install. Will most likely add a second one next year.

Works great

Very good product.

Convenient and easy to use compartment heater that does the job right in protecting your boats engine during the cold off season.

So far it has worked very well. I graph the temperature and it’s been very reliable. Expensive but I sleep better with it’s reliability.

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.

Unit is built heavy duty with a very long cord small and compact puts out lots of heat in the fan will keep it circulating good
