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

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

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!

Looks like a great product.

Installed as a pair... Worked well to help delay winterization and keep the diesel engines ready to start when temps dipped into in the low 20s last month. Recommended.

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.

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

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.

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

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.

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.
