I have a four litre tank on mine to heat the cab on a VW T5 so not really a lot of space to heat. Eberspacher airtronic d2 has a max fuel consumption of 0.28 l/h down to 0.1 l/h. Running at max for 8 hours would use approx 2.24 litres. I think the controller also influences the amount of fuel, the one I have automatically regulates the output. At start up it runs at max then as it gets closer to the target temp it reduces the fan and fuel pump.
