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

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

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.

Surprised at how small it is. Runs quiet and noticed that the salon floors dont have a cold draft now. Nice long cord.

Worked as advertised. Maintained 40°-50° in my bilge during 20° weather.

I recieved my order early, in good shape, solid packing. It came with a detailed user and setup manual.

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.

Kept my boat at 50 degrees on the coldest day

It is exactly what we expected!

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