This isn’t any old hot water heater, these heaters are extremely efficient, effective, reliable, AND hot!
 
Stay with us here and we’ll tell you why.

First, you can heat your water simply by running or driving your van! This hot water heater can heat water by using your van’s coolant lines or by using the 750 watt (120 V) electric element off your inverter and battery bank when you’re not driving.

Second, these heaters are marine grade so they can withstand all the elements. Stainless steel, built-in linings, as well as efficiently designed tubings and fittings which keep everything safe from corrosion. This is the only square profile Slim model which can make it easier to install into tight spaces in your van build.

Lastly, these heaters are effective. While a lot of hot water heaters have their own implied time limit, (hopefully it’s over 10 minutes.) these heat from the bottom and have tightly insulated fittings to ensure all that hot water stays hot, doesn’t mix in with the dreaded chilly counterparts, and keeps heating from the bottom up. 

If you want hot water with quality, and more importantly quantity, this is our first pick.

Key Features & Benefits:

  • Most Efficient Water Heater - Drive around, get heat, repeat. This could be the start of a great theme song! Seriously though, this heats by driving your vehicle, saving you both electricity and time while waiting on a shower.  
  • Consistent Temperatures - You may be concerned about your water not heating enough, fair, but too hot is a real thing as well when you are in a hurry. Burns aren’t great for one, but this comes with a thermostat mixing valve so you and the kiddos won’t even have to think about that. 
  • High Performance and Efficiency - Extra thick insulation and well-thought-out fittings keep this heater performing as it should.

You will be enlightened
Format: Paperback
Per the author, this book is “intended as a supplement to existing literature on African and Black Hebrew history.” If you are not looking for such, this will not be the book for you. This may be why some reviewers find the book to be a disappointment. What makes this book great is that it is detailed-oriented, factual, and intends to drive points home for the reader. Even more, it sparks your curiosity on the subject matter, as intended. Many of us have been brainwashed and forced into believing historical occurrences that are false and biased so I can understand why some individuals find this book challenging to accept, believe, and understand; however, that’s what makes the book great –it encourages you to research and to come to an educated conclusion. I have been enlightened by this book; however, it is repetitive in some areas. It is not written as most of our “modern” books, following certain standards of writing and, therefore, can be considered challenging to read, but after I finished it I was happy that I did read it because my world has become even larger. Yet, that does not discredit the author or the book itself. This is not your typical book and as it is a supplement, be equipped with a search engine, history books, the bible, and more. I promise that you will see most of the points and historical accounts provided are indeed true.
