Marine, RV & Industrial Heaters That Prevent Freeze Damage

Saw this unit promoted on "Mathers on the Map" YouTube channel and decided to give it a try. Has not been cold enough to place it in service yet, but compact size and rugged construction portend a warm engine room this winter.

I don't own a boat or RV, but I do need to keep temps above freezing in my outdoor utility closet in my condo. I have water heater and gas pipes in my utility closet. I needed a reliable heater that keeps its thermostat settings that I can just plug in and forget about. I don't want to have to keep monitoring a space that's not inside the apartment. The Large Xtreme Heater 800W is perfect for the small 2'x4'x10' closet space. Its mountability and stability without mounting was a consideration. I don't want to have to mount it until I'm sure its optimal place, but I also want it stable for peace of mind. As soon as it arrived, I just plugged it into the wall. It revved up and then the light turned green and it's good to go. Perfect. Just set it and forget it. Now I don't have to worry about pipes bursting or keep checking the temperature remotely all winter long. And honestly this Large sized heater takes up very little space, so it doesn't look cluttered in the utility closet. These Xtreme Heaters were truly a find. When I called to ask questions, Ed was patient and answered every question. He suggested the proper size I needed and never tried to sell me more than what was right for me. Xtreme knows about heaters for keeping things that shouldn't freeze from freezing in all environments. The heater itself is well made and safe. I trust Xtreme to get me through this winter and the winters to come.

I received the 2 800W heaters and did and plugged in to do the test. It all checked out as it should. The real test will be this winter in Nebraska. Using in an enclosed and insulated crawl space.

Incredible heater, absolute work horse. Just got me through a week with wind chills reaching -15 in New Jersey.

Hello.I just want to say..I did in order in a Monday morning and I received it in Colorado the next morning..You heaters work amazing. Thank you for the products and quick ship

I bought mine on the recommendation of a friend who is a lifelong sailor. My use for it, however it is different than his, in that I am keeping a room warm in my shop that I use as an office. It is generally poorly insulated. Having done everything I can to mitigate it, I had a space heater going a lot. My friend recommended the extreme heater, and I thought I would give it a try. At first, I didn’t think it was keeping up very well and I was concerned because I had the temperature control with about the 2 o’clock position on the 750 W setting. In order to keep the temperature where I wanted it. After a day or two of acclamation – read rhea materials absorbing the heat. I now have it set at about the 8 o’clock position much much improved. The heat is also much more evenly distributed than it was with the space heater. I’m. I’m very happy with my purchase.

I use it in the storage compartment to protect the plumbing. I was using a space heater which didn’t feel safe and that was a cloud over my head. I’m glad to have found this product.

Great Product!

Installed on a 2007 Four Winns Horizon 240. Perfect solution to keep from having to winterize since our winters are mild in the southern US and we can boat pretty much year round.

Works as intended. Small in size and worked great to keep my camper warm during these cold temps over the last few weeks. Happy with the purchase.

Great company stands by their products. We have a problem with one of our heaters reached out, sent back the bad one and they received a replacement. Thank you for a great customer service.
