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

First big dip down to the freezing mark of the season, purchased this heater to simply sit in the bilge for our 24 footer which lives outside on a lift at the marina. As I write this, just checked on the boat at the marina for the first time, it is 37° outside temperature, I have a big winter cover on the boat, went inside and pulled the bilge cover, and this mighty little heater was on and the entire bilge and engine block area was very comfortable and warm. first check of the new heater of the season so I’ll reserve judgment for durability, but at this moment it is doing exactly what it is supposed to do. Wonderfully happy and extra peace of mind.

So far the heater is working properly. Very sturdy and easy to handle. The only downside I have experienced with this is the screws that came with the product were not very reliable. The heads broke off 3 out of the 4 that came with the unit, even with a pilot hole drilled.

Easy to install! Gives me more use of my boat in the winter. I live in the south were temps almost never go below freezing for a few hours and gives me peace of mind that the engine compartment is nice and toasty!

The 300w extreme heater is solidly constructed and has a very substantial cord (glad I didnt need an extension cord to reach an outlet). This is a perfect size for my Mastercraft Prostar 190. Winterization can cost several hundreds of dollars and boat storage fees also add up over time. I calculate that this heater will pay for itself in the first year and allow me to keep my boat on the water throughout our mild Southern winters. I wanted this heater to extend my season for the unseasonably warm fall days and allow me to take cruises in the early spring as well. Now I dont have to worry about the block cracking during a freeze because I know that this heater will keep everything warm. Very glad I purchased this product. My only regret is that I didnt order one sooner. Happy boating.

Works great

Ordered this product from the advise of a good friend and it has been everything that I was looking for. It has been a cold winter this year in Texas and this heater has performed as advertised. Has kept the engine compartment on my boat warm enough that I am not concerned about any engine freeze. It is compact in size and I am glad I made this purchase.

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.

Plug and play operation. Just plug in and set the location and your set. Works great for well casting or boat

This is exactly what we needed to keep the bilge warm for the winter in Charleston. Easy to install, good directions and lots of safety features. It was recommended by someone who has them over the years and they are reliable.

Keeps engine compartment nice and warm on my wakeboard boat. Ran pick antifreeze through it , but these boats have tanks , pumps water lines all over. Heater gives me piece of mind I wont have a problem if I missed something.
