Let customers speak for us
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.
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.
So far it seems good
Winter has arrived and my Chris Craft Riviera needed a little heat for those cold nights. Xtreme 400w took care of my concerns. A perfect, simple solution for winterazation.
Im super happy with the heater so far...My heater was delivered fast...I have used it for about 3 weeks now, and have had no problems...Thinking about buying 2 more...Thanks
Love them! But recommend one heater for every 10 feet of RV underbelly if living in extreme negative temperatures! My 40 foot RV is skirted, foam board behind the skirt and insulation around the edges on the inside. At first we had only 2, we added a third and will be adding a 4th. What a difference! Currently my temps are in the mid 50’s, hoping once we add number it will be in the 60’s. And it has made a huge difference for inside the RV too. Very happy!! THANK YOU!
I don’t know why I just learned of these! I have a sprinter van converted to a camper van with a complex electrical system and a huge investment in lithium batteries! I live in Illinois where it gets cold I have added this heater and it keeps my batteries above the danger zone! These are the safest option on the market it’s truly set it and forget it and I don’t have to worry about this thing catching fire! I recommend anyone with a large investment in lithium to have one of these it’s cheap insurance!
My experience with Xtreme Heaters has been just what I expected. High quality product service and support! Well done team Xtreme!
I just started using a 600W heater for under my travel trailer in conjunction with Airskirts. It's been unseasonable cold (high 20's) here in TN and I'm putting the heater to the test. So far, it has worked perfectly and unfortunately, I wasn't able to try both with a little warmer temperatures. Even if the Xtreme Heater ran at 600W for a full 24 hours, it will only cost me around $2 per day for electricity. Small price to pay to keep the water lines from freezing! Customer service answered my call right away and provided excellent and friendly advice. I think the Xtreme Heater/Airskirts combo is a winner!
