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.

  • 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.

Cute, Comfortable, Light-Weight Shoes, Perfect for School
Size: 11 Little Kid, Color: Pink/Lavender, Size: 11 Little Kid, Color: Pink/Lavender
These have turned out to be great everyday shoes for my 5 year old. She normally wears a size 10, but since that size wasn’t available, I ordered the 11 expecting her to grow into them. I was pleasantly surprised that they already fit her pretty well. There’s still a little extra room in the toe area, but the shoes fit securely around her ankles so they don’t feel loose or slip off while walking or playing. She says they’re very comfortable and loves how easy they are to slip on by herself. The lightweight design is nice for everyday wear, and they’ve held up well so far despite being worn almost daily. They've become her favorite shoes to wear! Also the pink/lavender color is really pretty in person. Overall, I’m very happy with them and would order again.

Great shoe well made
Size: 13 Little Kid, Color: Pink/Lavender, Size: 13 Little Kid, Color: Pink/Lavender
Really good shoes at a fair price. My daughter loves the pink and purple gradient colors. Really beautiful. Shoes have proven themselves very durable. She's been wearing these a few times a week for the last couple months and they still look new aside from some dirt stains. Fit perfectly. Very comfortable. This is always her first pick in the morning when she's getting dressed. Good breathability you can wear these in hot summer weather without sweaty feet. Versatile shoe looks good enough to wear out and about or exercise in.
