Ian.I have one (2ft long) and I also have an energy meter which tells me that mine uses 3-4 pence per hour Bob
try an oil filled radiator for that maybe? thats what i have, and that has a thermostat on it.vans, so far, been toasty and frost free even on the front screen!
thats why you have a thermostat on low...so it kicks in when very cold, not on full whack constantly.
Ian.Minus 2 here last night so I put the tube heater in the van overnight.Nothing was frozen this morning but it certainly wasn't warm. I suppose the heater keeps the temprature just above freezing which is absolutley fine.Bob
I laid it on top of my small A frame ladder last night but it did come with 2 clips which can be screw to the top or side of the van and then the heater clips in.There heater was very hot so thats why I paid it on the metal ladder.Bob
