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

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

I have 2 in my engine room. One units fan starts and runs as long as it is plugged in. Had to drill out rivets to disassemble. Moved fan circuit to load side of thermostat. Now fan cycles with heating elements. Not impressed with pop rivets, or fan running continuously. Bought 750 watt Twin hornet for my other boat. Works as it should.

GREAT

I installed this in a small greenhouse I have to protect it on occasional cold nights we have. I can put it in and forget about having to plug in a space heater. Before if I forgot to turn the space heater off, the greenhouse would get too hot. Great for when we travel. No worries.

Great value of product

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.

Very good product.

Used this to help keep boat heated during the winter. Decided not to take off slip this year as friends told us to try this. Husband said it worked.

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!

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.
