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.

Rottweiler approved
Color: Purple
My Rottweiler puppies love these bones. I feel good about letting them play with these and not worry they will break or that they can choke because they are durable and a good size and weight. I like the variety and can put peanut butter on the crevices if I want to give as a treat. Worth the money!

Perfect for the aggressive chewer
Color: Purple
I purchased these because I have a 1-year-old black lab redbone coonhound mix who destroys every toy and Bone. I have gotten him in a short amount of time... These things have outstanded this little guy and he is still enjoying them! Keeps him occupied and satisfies his chewing for hours! And he leaves my shoes alone haha

Best for all chewers!
Color: Purple, Color: Purple
I purchased in February and waited until ive had them long enough to make a justified review. I have a very VERY aggressive chewer. He destroys every toy he gets within minutes or a hour. We didnt expect much out of these but why not. Let me tell you... they only have small teeth dents. No cracks, no breaks, no chunks missing, none in the trash, no bleeding gums... nothing. My chewer loves them. First day he just stared at them like they were alien objects but after we played fetch a few times it was on!! Now all three dogs chewer on them. I would say im purchasing again but I dont know when that will be lol I highly recommend to anyone!! Photo is taken today 6/4/26

My pit bull loves them.
Color: Purple
I picked up the Frienhund Tough Dog Toys 3-pack for my large, heavy chewer, and overall I’m pretty impressed. Right out of the box, the toys feel solid and well-made—definitely more durable than your average chew toy. My dog usually destroys new toys within a day or two, but these have held up significantly longer, which is a big win. They also do a great job of keeping him occupied. The shapes and textures seem to keep his interest, and I’ve noticed less destructive chewing on furniture since introducing these. That alone makes them worth it. The only reason I’m giving 4 instead of 5 stars is that while they’re very tough, they’re not completely “indestructible” (despite the claim). After a couple of weeks of heavy use, there are some visible wear marks. Still, compared to most other toys we’ve tried, these last much longer. Overall, a great option for medium to large dogs that are aggressive chewers—durable, engaging, and a solid value for a 3-pack.
