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

5 stars all of the way around!... Lost a pump due to freeze, and a failed pump box heater. There would be no other choice

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

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.

Product has worked as expected. It has kept the engine area between 42-55 degrees with outside temps in the 20s Update 2nd winter season. Temps got to 8 degrees outside. Engine area of the boat never dropped below 40° Great little heater.

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

Looks like a great product.

Very good product.

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.

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.

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.
