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

Great purchase. Plug and play. Winterization cost me $600.00The heater cost $480.00.Do the math. Very good.

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.

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.

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.

1st impression when unboxing -- man, this thing is built tough! And that continues to be my impression after utilizing it through this mild winter. Now the hard part of reviewing its operation. I utilized it in my boats small cabin throughout the winter since I cant use it in my small bilge due to power cord routing problems (I would pinch the power cord after placing it in my bilge and closing the bilge hatch. SO using it in the cabin area? Well lo and behold we had a relatively mild winter and I noted that the water temperature (and thus the cabin for the most part) never really got below 43 degrees F that I know of. The heater did kick on the few times I was there long enough to observe. But it didnt seem to run for any length of time, and certainly didnt kick-on long enough to attempt to bring the temperature up to 55 degrees F. That part is a bit perplexing to me since I would think that even with testing (using a refrigerant spray) to bring the temperature down you would think it would continue to run until it brought the 43 degree surrounding temp up to 55 degrees. But it never did that, it would run for a short time (even with strong 43 degree air circulation in the area) and then shut off. Again, it may be because of the warm winter. Even though most of my bilge area is below the waterline, thus remaining at the seawater temperature for the most part, I do plan on mounting this permanently (with the quick latch) in the bilge area and running the wiring to a gunwale receptacle so that shore power can be plugged into it directly (no wires through hatches). That way I can set it and forget an only run the shore power to that receptacle in the winter. Ill also look at mounting it high in the bilge compartment since that is the area that will be most influenced by the above the waterline temperatures of the outside air vice the surrounding water temperature.

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.

Been riding the danger wagon for a couple seasons with a traditional ceramic heater to keep the engine room ice free during our Alaskan winters (southeast Alaska) and finally decided to hit up Safetown,USA and spring for one of these. Long cord (20’) is super helpful to make it to a dedicated outlet and leave the surge protectors and y splitters for the birds and the bees. Didn’t seem to push a lot of air at first so I wasn’t sure what was up but after a couple days I saw the temp rise on up during a big freeze we just had. We monitor our boat remotely- 40’ Tri-cabin trawler- and had readings of 8° F outside and engine room read out at 32° F so I’m super excited to say this one gets full support from us! No frozen pipes here! Also: we get power outages from time to time in our remote Alaskan town and have made plenty of trips back to the boat to reset the older heater we ditched but this one just turns back on when power comes back. Bingo big time baby!

Had one in my boat for 10 years runs perfectly .Well worth the money not to winterize for that long .Do yourself a favor and dont by a cheaper brand trying to save a buck .By the best .

Very good product.

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