Probably no one thinks "I should get a heater" at this time of the year but this heater is reduced to $174 so maybe get one for next winter?
There are also two units from Amazon Warehouse at $160 each.
I have two of these at home and love how quick they heat up a medium-sized room. They're a bit loud for my liking but I get used to the noise level quite quickly.
They are also very energy efficient as they tend to run for about 2-3 minutes every 30 minutes.
I also bought the version without a remote control but returned it as it was difficult to adjust temperature (no digital control) and no remote control.

  Costco are trying to clear this for $5 more. Wonder if it will take another price hit if interest is low.

  Any idea if this would be more efficient than a wall reverse cycle unit?

    Hell no. Heat pumps are king, they are like 300-600% efficient (at converting electricity to heat)

      600% would be very impressive. Typically they're more around 3.

      Just to be a bit picky on the wording here haha. They technically don't convert electricity to "heat". They use electricity to do work to move energy from one spot to another. In cooling mode, they move energy from inside the room, to the outside of the room - cooling it down. In heater mode, they move energy from the outside, in.

      This is why they're a lot more efficient then oldschool electric heaters - they're moving thermal energy, not creating it.

        the COP ratings on inverter ACs are hitting 5.0 and above - i.e. the MSZ-LN25VG has a COP rating of 5.52, the MSZ-LN35VG has a 5.0. Your much larger units will sit in the 3.5-4.0 area.

        Looking at the Vornado, it is essentially a COP rating of 1.0, so the 600% is pretty close when comparing to the 25VG, but you are looking at about 1000% price difference :P

            @incipient: No worries - we are living in the best temperature control time line haha.

            For some reason I can't find the documentation anymore, but from memory the MSZ-AP15VG uses somewhere around 300w to run and puts out 1.5kW of cooling - can't remember the power usage for heating, but was around the same. People are installing them in motorhomes now, running them off a single solar panel!

    Depends on the size of your room. A wall reverse cycle unit would be more suitable for rooms larger than 20m2.

  These are no more efficient than the $20 ones at kmart.

    I disagree. The lowest usage that I recorded in this winter was 0.5 kWh for 6 hours of use. The highest was 3 kWh in one of the coldest nights in Canberra.

      They just have an efficiency of 100% - just like any other cheap heater. Every resistive heater will be pretty much the same - some are better at distributing the heat - some look better and have nicer materials - but they all use the same power and are pretty expensive to use.

      When you want something more efficient get a split system / heatpump !!! 400% or more is possible - so far cheaper to run. The best part: most people have them at home already to cool (but did not think yet to use them to heat the house!)

      (I personally turned off my gas ducted heating and used the split system to heat up the house this winter. In combination with better insulation (and draft sealing (so many leaky spots!!!) I wiped out my $350 gas bill and the electricity maybe went up by $50.

        Reverse cycle units have been a thing for many, many decades! I'd be surprised if many people at l had single cycle.

        $50/mo, would be a 9kw unit (3kw of power - a small to mid sized ducted aircon) running for about 5-6h/day (assuming 33c/kwh). Just to give someone context.

      The lowest usage that I recorded in this winter was 0.5 kWh for 6 hours of use. The highest was 3 kWh

      What that means is that one night the heater put 0.5KWh of heat into the room. And it used 0.5KWh of electricity to do this.
      And on the other night, it put 3KWh of heat into the room, and it used 3KWh of electricity to do this.

      This is exactly the same as a $20 KMart heater would cost to put 0.5KWh or 3KWh of heat into the room.

    Ok I maybe wrong, these probably are using a brushless motor for the fan which would make it more efficient than your el-cheapo brushed variant.

    But resistive elements remain the same. Down vote physics, not me.

      No, you were absolutely right.

      These are no more efficient than the $20 ones at kmart.

      It doesn't matter whether it's using a brushed or brushless motor - because the motor inefficiency is lost as heat anyway…

  They are also very energy efficient

  No, they're really not. These things are 1:1 power draw vs heat generated. Physics says it can't be anything else.

    This.

    Electric heaters are all 100% efficient…

    …which is terrible compared to a split system which can be somewhere around 400% efficient.
