Eberspacher vs Planar diesel air heaters.

3. I was Google'ing "Planar Diesel Heaters" and found this guy who installed one of these things in his camping trailer: https://www.4wdtalk.com/planar-diesel-heater-review/ he has a 2kw that is heating his tent. The video they have in that article doesn't go into much detail on the heater, but I did find this video https://youtu.be/S-wm-cv7Xds on their channel that IMHO seems more appropriate for that article as it speaks more about the heater. So looking at his setup, that metal exhaust that comes out the bottom of that heater, how do you deal with that in a boat with out melting the side of the boat?

Thank you!

A gas/petrel heater is a burnt to the waterline solution.

Better not to buy too big a unit, thermostat running it low creates higher maintenance issues.

They like burning WOT, and yes kero helps.

There are also those that heat up hydronic calorifiers, tap into the engine coolant circuit, distribution under the sole or along the cupboards, very efficient with an insulated tank, but yes lots more complex
