I have one of the typical Truma Room/Space Heaters in my 2007 Motorhome (S3002 or S3004 model I think?).
Does anyone know/confirm from experience how much LPG/hour it will burn on the lowest setting (1 out of the 1-10 range)?
The specs I have found for the S3004 say:
"Gas Consumption: 30–280 g/h" - which ties up with a control range of 1 to 10 if they are all equal steps.
There are 1.96 litres in 1kg of LPG, so 30g = 60ml near enough.
If paying £1/litre for LPG, 60ml of LPG would be 6p/hour to run the heater.
The relevance of this is that I am finding the Gas heater, even at the lowest setting seems to be much more effective at increasing the motorhome interior temperature then the 400W min oil-rad, which uses around 250W/hour (it cycles on and off which is why it is not 400W/hour). Current rates, 250Wh costs about 9p/hour.
I have the fan on the Truma heater running so the heat is being circulated better than the radiator, but it seems remarkably better even at the very lowest setting, which I think is 350W? (it is a 3500W rated heater, so if position 1 is a 10th of position 10, 1 should be a tenth of 3500W?).
Does seem to be the case that it is cheaper to run on the on-board gas than to plug into EHU for heat (answer may be different if using Calor bottles where the price/litre would be a fair bit more though?).
Right now I am running a pattern of having the Truma set low and running on Gas during the day but turning off in the evening and letting the plug-in radiator take over as not keen on totally unattended gas fires.
