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

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.

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.

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.

This is the second Xtreme heater Ive bought. Great engine room heater, still using the first one and after six years, havent had any issues. Would recommend if you need a dependable engine heater.

works great on our boat motors for the winter!@

I have 4 SOK 206 amp batteries in a bank that I need to keep up over the winter. I had to bring them inside due to the extreme cold and put them on a charger to maintain them. The charger brought them back to the storage voltage and they are doing fine. Then I installed this heater in the battery/ electrical compartment of my RV which is only 120 square feet, and reinstalled the batteries. The heater is running on one of my Renogy inverters. Now the space has stayed 40+ degrees and the batteries haven’t had any issues. Cold weather and batteries are mortal enemies but this little guy came in and saved the day.

This product has high reviews for a number of reasons. First, our boat, 25 ft. Sea Ray is docked during the winter in our boat house in North Texas. We do enjoy using our boat during nice winter weather and prefer not to winterize our boat. This product is placed in the engine compartment to keep the cooling water in the engine from freezing. The heater turns on automatically when the temperature is below 40 deg F and maintains the compartment temperature high enough to prevent engine and bilge compartment. The heater is safe to use in a closed compartment where fuel vapors may be present. We do add fuel stabilizer in the winter and trim down our out drive to drain the water from the lower unit to prevent freeze damage. Very satisfied with the product which pays for itself in a year compared to on dock boat winterization services. The heater must have a continuous 110 V electrical supply to function. Very satisfied with this high quality marine grade heater.

Used it while trying to figure out how to winterize a boat. Winter storm came through and encountered no problems.

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