    All the thermal electric heaters cost much the same to run (reverse ac being the exception).
    If it is for your bedroom when you awake the best will be a cheap fan heater that can quickly warm you and the air. Just turn it off after a little while when it has taken the chill off.
    If you are cold in your bed, you really need a better doona/blankets and a hot water bottle or electric blanket.
    Heating the room while you are insulated under blankets will be costly and ineffective.
    A good rule of thumb is a 2000w heater costs 50c per hour to run.

    • how do you know 2000w heater costs only 50c per hour to run, is there any calculation or written any where ? why i am asking is i have 4 in house i dont like to use it, was thinking its going to be expensive

        Well, the upper limit is gonna be 2 kW of electricity per hour. Let's say 25c per kWh (if you don't have something like off-peak). That's 50c per hour.

        In reality, it's obviously going to vary depending on how your power is priced and what temp you set.

        If you're talking convection space heaters, it'll also depend on how good your insulation is. It's not going to be running (at 2 kW) the whole time. Once it reaches the set temperature, it'll shut off until it cools down below a certain point. In a well insulated room, it'll spend most of its time off once the initial heating is done.

        In reality? You're probably looking at more like 10-40c/hr. Yes, that's a massive range.

        If you really want to know, stick a meter between a heater and the wall.

          Just look at the device to see how many watt it is rated at. 1 kilowatt(kW) = 1000Watts (W).

          Power is measured in kilowatt-hours (kWh) at the meter, how many Watts divided by 1000 to convert to multiplied by how many hours it is run for. A 1500W heater is 1.5kW, run it for an hour at peak tariff of around 42c/kWh and you are looking at 1.5*0.42=63c/hour.

          It is true that the heater will not run at full rating all the time, but you can work out worst case power consumption by that.

          We've got a column oil heater for one of the kids bedrooms, nice just to keep the chill off the room during winter when set on low.

          Don't forget to wear a jumper and keep the door shut!

        • Thank you guys for giving me lots of information :)

    @mskeggs - Solid advice. A $15-20 job from somewhere like Kmart or BigW should do the job fine.

    What type you get (fan, column, bar radiant, etc) really depends on how you intend to use it. I'm rather fond of the glowing radiant bar type, as they heat up instantly and radiate the heat directly onto you. When I lived in a really cold house, i used to have one i'd stick on for 5 minutes in the morning while i got dressed in front of it, and it was great.

  • We have a couple of the ceramic fan heaters, one for the bathroom (with a safety cutout) and one for the bedroom. They do a good job of heating the room for a short time whilst dressing etc. I agree if you are cold overnight then get better bedding; it is passive heating which doesn't cost anything.
