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.

Dimensions & Specifications:

  • 4.2 US Gallons / 19 Litres
  • Stainless-steel AISI 316 inner tank
  • Extra thick insulation for high performance.
  • Outer casing made of high-quality polypropylene.
  • 1/2” NPT water connections.
  • The thermostat mixing valve protects against scalding and delivers consistent temperatures at the faucet.
  • Standard 750 watt immersion heating element heats the water quickly but will not overload generators or dock breakers.
  • 6 bar safety valve
  • 5-year limited manufacturer warranty

Soft, medium quality
Ok value for the money and doggies liked it. Not very durable but certainly more durable than some. Stitching is good and is ok - good toy overall but nothing exciting and not super durable though far better than some toys that just fall apart. And if your dog isn’t a toy killer this will be a great toy!

My dog Ed gives it two paws up
I have four dogs. One is completely in love with his toys. One is so so about them. The two others have no interest. I got this for the so so dog and he liked it, but only in small intervals. He left it for my other toy loving dog, Ed. For him, it was love at first bite. He took it and happily cuddled with it, threw it around, and watched with an adoring look at the flailing arms. The little squeaks thrilled him (to the chagrin of one of the other dogs who hates squeaks). Definitely a great buy and super cute.

Not the most durable, but it is a quality toy
I bought this as a gift for my friend's mini dachund and I knew she would love it because of the long legs and how soft it is. She loved it alright. So much that she ripped the ear off in the first 10 minutes of having it. It's not durable, given a year old mini weenie can rip it, but it is a good toy for the dogs that don't choose death for every toy they have.
