Diesel heater : in - or under the van?

[Peter7]

I would like to install a diesel heater in my Fiat Ducato camper van (2013).

What are the pros and cons of installing the heater under the van versus inside the van?

I am considering installing the heater under the van, as the preferred spot of placing the heater inside is not possible (just above the exhaust filter).

Do I need to protect the heater from stones that might hit it when installed under the van?

Most of those heaters are designed to be installed inside or in a protected enclosure. Not just stones but weather can work inside them and cause havoc. It is easier to deal with the 1" combustion intake and exhaust than the air duct hoses. Smaller holes in the floor.
Keep in mind that most of these heaters do not have any agency safety agency listings for use in an RV or dwelling. Any incident of CO poisoning or fire will be bad day. Find the required installation codes for heating appliances and follow the best possible. Exhaust distance form doors and windows and attention to snow lines. CO and Smoke detectors a must. These low-cost heaters are fantastic in many ways. Europeans have had and used them for decades, just at a much higher price point. There are some now that also heat water or coolant. Deisel engine pre-heat! The efficiency of these units is awesome. A lot of really good options. Just be careful and install, use them safely.

Also remember that they should be classified as a furnace rather than a heater. The difference is forced air.

You will be draining power from the house bank as part of the equation, so take that onto account.
