"The Van Life Tech radiant heat and hot water system is unreal. My girlfriend and I just spent 3 months traveling full time in our van this winter [2019-20] skiing after getting this system installed. We drove around 18k miles, and visited 38 ski resorts. We experienced outside air temperatures below 0 F, elevations over 10k feet, and never once had to worry about the system; it was flawless. It was turned on in December when we left on our trip and we never thought about it again. With our well insulated and well sealed van, fuel consumption was minimal (I'd estimate maybe a gallon a day on a cold day) and electrical consumption averaged around 25 watts. The best part of the heated floor is warm feet and the fact that interior heat recovers very quickly when a door is opened. Hot water is instant and never ending (until you run out of water in your freshwater tank)! The ability to check and adjust temperature over WiFi from a ski lift to make sure our dog was comfortable was an awesome bonus. This system may seem expensive, but when we added up components to do a good job heating air, potable water, installation, floor insulation, etc, it became clear that the additional investment in the Van Life Tech system was well worth it."
