There are mufflers for the exhaust. No idea on how well they work - or if they affect the burning.
The diesel will give off the smell of burning diesel. Propane is clean -- no fumes. The only possible failure is due to incomplete combustion due to the intake or exhaust being covered.
Although mentioned above/below?, I think the idea of having a thermostat is really a major benefit. Propane can ignite/reignite very easily. In addition, you save on fan runtime/power consumption. Diesel heaters do not have thermostats - hence the constant on. I suppose in the middle of winter, you might not ever get too hot. But for the shoulder seasons, it would be nice to add only a little heat.
A positive for propane is the lower maintenance cost. The diesel heaters do foul and require some fixing or replacement. In listening here, I believe several diesel heater users have said it is cheaper/less expensive to just replace the units than clean them.
A minor negative point for propane is there is an altitude limit ( 9,000 feet??). It is in the manual. The same issue with camp stoves and high altitude.
Also as stated, if you are already plumbed for propane, you can run the heater anytime. Even the 1 lb cylinders would be nice. Small, clean, safe -- and quick to attach as needed.
The major drawback of the propane heaters appears to be the price. I have not seen or heard of cheaper version/cheaper manufacturer. No Chinese knockoffs. You will have to pay for it.
