This is the ultimate water heater for mobile living- every Sprinter van should have one!

The Incline Heat Transfer Water Heater uses excess heat from the engine to rapidly heat and maintain 4.2 gallons of water, providing hot water every time you start the engine and reducing the amount of power you need to heater water by 95%. 

Inside the insulated tank, the heated water will stay hot for ~12 hours. If you’re stationary for longer than that, the electric heating element will keep your water up to temperature indefinitely. Simply connect the heater to your power system and set the desired minimum temperature. 

This durable unit was designed to mount neatly under the passenger sliding door of a Sprinter van. The optional install kit comes with the necessary mounting straps and hoses to quickly install the water heater with minimal fuss. Made of 3/16 thick aluminum, the main heater core is nearly indestructible, won’t rust and is designed to take a hit from rocks and sticks without failing. 

Heater Dimensions:

34" Long x 10" Wide x 6" Tall
Overall length with fittings: 40"


4.2 gallons

The optional Sprinter install kit includes:

  • Mounting brackets and hardware for Sprinter 2007 to current model year.
  • Expansion tank for hot water line.
  • Heater hose, hose clamps, elbows and hose mounting brackets.
  • Mercedes-Benz approved engine anti-freeze/coolant.

Choose Your Heating Element:

There are two options for heating your water via electricity- a 12v DC heating element (200 watts) and a 110v AC heating element (1000 watts). The 12v element is best if you do not have a power inverter since you can connect it directly to your batteries. The 110v element is best if you want a fast heating option. This will heat the entire water tank in a few minutes, but does require a connection to your AC power inverter. 

Freeze Protection:

The included DC heating element is adjustable from 50-190 deg. F. When parking for extended periods of time in freezing conditions, either keep the heating element set to 50 or drain the tank so there's no risk of freezing.
