Xtreme Heaters Testimonial Xtreme Heaters Testimonial I am in the cold chain monitoring business for commercial trailer and warehouse temp monitoring. With these temps, I am always comforted to get alarms if bilge temperatures drop. I was getting little anxious not seeing a heat rise till last night when your heater performed as advertised. Was intrigued with the these trends. I would have thought the bilge would have been much colder with the ambient so low. It’s really encouraging to see how your heater is performing. Great testimonial to your product. Spot on at 40F trigger! Brad Bartlett After their excellent customer service, I purchased their 600 watt unit for my boat!
