Perfect for my boat
The Webasto EVO55 heater kit is a fantastic product. It's easy to install, efficient, and incredibly quiet. I installed it in my boat and it has been a game-changer. It heats up the space quickly and maintains a consistent temperature, even in cold weather. I highly recommend this product to anyone in need of a reliable and efficient heating solution.

Arrived on time and easy to install
The Webasto EVO 55 heater kit is a great addition to my camper van. It's compact and easy to install, and the fuel consumption is minimal. The only issue I have is that it doesn't work very well at high altitudes. It struggles to provide enough heat, so I have to supplement it with extra blankets. Other than that, it's a great product.

The installation was a breeze, and the heater is incredibly efficient and quiet. It warms up the space quickly, and I've noticed a significant reduction in fuel consumption. I highly recommend this product to anyone in need of a reliable and efficient heating solution.

Easy install
I recently installed the Webasto Air Top Evo 55 in my van and it has been a game-changer. The installation was relatively easy with the included manual and I was able to complete it myself. The heater is very quiet and efficient, providing ample heat without using too much fuel. The only downside is that it takes a little longer than expected to warm up the space, but once it does, it works great.
