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 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.

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 .

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.

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

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

It is exactly what we expected!

First big dip down to the freezing mark of the season, purchased this heater to simply sit in the bilge for our 24 footer which lives outside on a lift at the marina. As I write this, just checked on the boat at the marina for the first time, it is 37° outside temperature, I have a big winter cover on the boat, went inside and pulled the bilge cover, and this mighty little heater was on and the entire bilge and engine block area was very comfortable and warm. first check of the new heater of the season so I’ll reserve judgment for durability, but at this moment it is doing exactly what it is supposed to do. Wonderfully happy and extra peace of mind.

Great value of product

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.
