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. 

Want some help with the install? Save yourself hours of research and multiple trips to the plumbing store, by adding our Install Kit for the Webasto / Isotemp Hot Water Heater!


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.

Perfect case for my daughter’s iPad
Color: Purple Pink
bought this case for my daughter. The fit is perfect — all the buttons and camera line up exactly and it snaps on securely. The case feels sturdy, protective, and durable but not too heavy, so she can still carry it comfortably. The stand feature is convenient. The design is also super cute — Luna loves it Overall, great quality for the price. I would definitely buy it again

Perfect case
Color: Purple Pink
Great protection for my IPad. I’m always dropping something. This case was pretty easy to install and has the protection over the glass front. No problem using the iPad with the cover. Cute colors and has a loop to store the pen

Very versatile!
Color: Colorful Pink
I got this iPad case for myself and my two year-old daughter as we both use this iPad. This case has definitely held up very well. I love the material because it’s nonslip so it’s easy for my two-year-old to hold I also love the movable and adjustable prop on the back that also doubles as a handle. There is two spots to put your Apple Pencil, so that’s very neat. It is a little bit bulky, but it is very protective and I think that is a good trade-off. There is also a cover for the charging port to prevent dust from getting in there or any spills. At first I was a little bit weary about it having a built-in screen protector, but it’s very clear and does not interfere with using the screen at all, so it’s actually a nice touch. I really love this thing and think it is worth it!
