I am a bit surprised.

What do you need that stuff for ?

Everything over -15 is not cold. ........ tells you a german, who is used to really "cold" winters. ))

Electric is the go if you have the battery capacity.

A mate turned up the other day with his new camper heater, it runs off one of those propane pressure pack cans.
Says he has to turn it way down or he cooks and a can of gas lasts over a week, not bad for $1.00.

I pointed out the small print on the side of the unit "Warning not for indoor use - CO is lethal"

Yep there are few shortcuts to staying warm.

Thanks for that Dorian I'll pass tell him about the alarm.

Now isn't that interesting! I was just thinking about hot water bottles as alternative to other forms of caravan heating (which are all pretty expensive). Then I checked a forum about alternatives to hot water bottles (which can leak... as mine did a little while ago), and saw that many people recommend heated throw blankets which are about $50 or so. I saw one advertised that's 100 watts, which means using an inverter it would draw just 0.5ah (approx). Sounds like the go to me! And if you want to move around the van to go to the toot or make a cuppa, you can wear the blanket like a robe to keep you warm. Gotta get one!

 I'm probably wrong but 100 watts divided by 12 is about 8.5amps plus inefficiency factor so I'd say about 10 A/H.    

I can just see you Gary - middle of the night traipsing out for a pee with a beanie on and wrapped in a blanket trailing an extension cord.....

Gary, you're on your own mate, why not get a long length of appropriate size drainage hose, run it out of your home on wheels to a nearby tree, you know the rest   That way you don't even have to get out of bed

 I think that's 100 watt at 240volt which would be around 0.5 amp. And for those of us who have lived a long time in the tropics anything under +15 degrees is fffffreezing

Yup - 0.5Amp when on 240volt, however Gary is using an inverter which runs on 12volts so that will draw 10amps.  

Right now it's 4 deg in Toowoomba, 16 deg in the house and I've just lit the fire.  We too lived in the tropics most of our lives but you do eventually adjust to the cold although my wife disagrees.

Thanks for clearing up the a/h thingy. I get confused about inverters and volts. As to extension cords and peeing in the wee smalls, I fixed that prob on my first shakedown by using an empty radiator coolant bottle (5 liters) with a wide neck like those hospital bottles. I helps in the dark when you're fumbling around, and the screw cap keeps everything tidy. Carrying the bottle to the amenities block in the morning attracts a bit of attention but what the hell.

"A/H" is an incorrect term.

"Amps" is the amount of current drawn from a battery wherease Amp-Hours (not Amps per Hour) is the amount of charge drawn from the battery.

Think of amps as flow rate and amp-hours as volume, or think of amps as the number of labourers on a job and amp-hours as the total work done by the gang (man-hours). If you double the flow rate or double the number of labourers, then ideally you will halve the number of hours required to fill a bucket or to get the job done. You wouldn't use the term "men per hour" (unless you were in a different line of work).

Still another way to think of it is to remember that 1 ampere = 1 coulomb per second. "Coulomb" is a unit of charge, so 1 amp is an electrical "flow rate" equivalent to 1 unit of charge per second.

1 AmpHour = 1 coulomb per second x 3600 seconds = 3600 coulombs

We like cool ohms..

Dougwe, can I borrow one of the twins (or maybe both of them) to keep me warm MATE, please

Wombat mate, simply put, NO. 

I have just got back from "The" beach where the twins are camped for the time being and I told them you wanted both of them to keep you warm but I think I got it wrong cos I told them they are really hot the way they were dressed.

Really nice beach too mate and I tell you that for free.

"Men per hour". Now there's a thought to make the mind boggle. You're right Capricorn, electricity can be funny

And wombat, with that avatar I wouldn't even lend you my 2 dogs to keep you warm. Talk about a barge-a**e, that makes me feel skinny

 Awww, sorry if I hurt your feelings wombat, no need to show me the nuggets

 I don't have feelings
