W51 in sprinter van supplying Hot Water with calorifier and engine pre heat.

Product is excellent. It is noisy as are all these hydronic heaters of this design. Used intake silencer and sound blanket over unit made it very quiet. Included parts are outstanding and complete; I used all of them. The controls work well. The instructions on the controller are very difficult to follow (almost worthless) but once you figure out how to set the control works great.
The unit itself runs flawlessly. It is the second one I have bought as I was so impressed with the first one.


I have this installed in my Hybrid camper (Rockwood Roo), it kept me warm down in single digits (farenheight) without any issues! Doesn't use much diesel and it's much quieter than a propane furnace. The thermostat isn't too accurate on the temperature setting, but you can usually turn it up high enough to maintain an average. I'm very happy with it and I'll be looking to add more of them to other vehicles!

Fan noise

 The unit makes a lot of noise from the fan not the exhaust. I believe it is defective. Message to the seller to exchange the unit will update when when I hear back from the seller
The sellers stand behind their product and refunded me for the defective product. I am very happy with the seller. I will try another one of their products.


This thing kicks so much heat it’s wonderful. Installation was pretty easy using the separately purchased turret and hole cutter. Been using for three or four weeks now in my van and i love it! I don’t know how i lived without this before. I would recommend 100 times, or more! Couldn’t be happier. Thank you.

Solid option

The heat is impressive, perfect , easy to use
