The all new Sparks Overland Diesel Heater 4K! 
Having many years in overlanding, there was one thing we have always wanted to perfect….diesel heaters. We have built them, fixed them, bought them and never found that sweet spot. We thought to ourselves, if you want it done right, do it yourself! 
What we have done is try to make the safest, strongest and most capable diesel heater ever made…. And we think we did it! 
The Sparks Overland Diesel Heater 4K has been designed to be the most user friendly diesel heater you can buy! Simply add fuel and turn it on.  It’s ready to go right out of the box.  The provided remote gives you simple controls from your tent/camper or take two more minuets to download the app and you have complete control of your heater from your phone!!! These are turn key units with no set up required. It’s not just easy to use, it’s smart too. 
Boasting an integrated computer that automatically adjusts the fuel consumption letting you get to altitudes of 18.5k feet! That’s 10k higher than our more expensive competitors. It gives you constant data to your phone including altitude, box temp, engine temp, heat adjustment, power consumption, time and timers and much more. 
   Then there’s the physical components. Our units are composed of 85% metal (aluminum and stainless) there are no plastic parts in our units! We have replaced any weak parts with metal giving us a much stronger, quieter and more reliable unit. No more leaky, plastic fuel tanks! We use a custom made 2.3 gallon tank from an Arizona company that makes tanks for dune buggy’s. The fuel pump is is a quiet espar unit. The air filter is a flat Wabasto filter and we use automotive fuel lines. One of our biggest innovations is our quick connect friction duct connect.  No more hose clamps!! You just push the hose on and done.  Unlike others we aren’t hiding our components or fit and finish, in fact we proudly show it off! We think looks are important as well.  The heater is visually appealing and opening the heater is like opening the hood to a show car. 
    All in all we think this is the most capable diesel heater available.  With such simple innovations like quick duct connect and a premium fuel tank, we are starting with things that should have been done from the start. We truly think you will be staying warm and happy with this heater for a lifetime!
