  I wish I'd spotted this deal last year….paid $500 for a used 15A Yum Cha brand from Ebay….it shakes because the fan is unbalanced :(

  This appears to be a good deal at face value, however I wasn't able to generate a shipping price for Melbourne, it's saying, "This shipping method is currently unavailable…."

  Additionally, it has a new energy star rating of 2 for both heating and cooling. It's therefore most probably not an inverter model, and will cost quite a bit to run in summer. 15A = 3600W x 12 hours a day (11am till 11pm in the peak of summer) x 25c per KWH = $10.80 per day to run.

    Your estimate's based on output capacity, which is the wrong figure to use. Thanks to the magic of heat pump technology, the output capacity is several times input power.

    • 

      [Deactivated] on 18/09/2012 - 18:21

      No, my estimate is based on 15A (for the larger model), which the unit draws in current. 15A x 240V = 3600 W. You are incorrect.

      • 

        mick01 on 18/09/2012 - 18:34

        You're 15A assumption is wrong though. The average current draw would be less than that, because the compressor motor doesn't run constantly.

      • 

        Jabba the Hutt on 18/09/2012 - 18:34

        You're right, in that I mistook which model you were looking at. Trouble is, your calculation is still way off, for the same reason I gave. The sustained input power of a 5.3kW air con will be nowhere near 3600W.

      • 

        [Deactivated] on 18/09/2012 - 18:44

        In the specs it says "Current rating amps : 15 amps". Can you explain to me how 15A doesn't equal 3600W because I can't understand how it doesn't.

        I do understand the duty cycle of the unit won't be drawing the full 15A all the time, but for some people (like me) who live in a 4 bedroom weatherboard home with - large dining and kitchen - no insulation in the walls - crappy rockwool roof insulation - concrete roof tiles - uninsulated hardwood floor - master bedroom/ensuit with uninsulated flat steel roof - the air con here is under full load for over 3/4 of the time it's on.

        Ok all you people need to take it easy. When they say cooling capicity is 3.6KW, its not 3.6kW of power. It just that the Air con can move 3.6KW of heat energy. Generally this takes a lot less electricity.

        My 5.5kW heting/cooling Air con only uses 1.8KW of electricity. That is, it uses 1.8kW of electricity to move 5.5kW of heat from outside to inside or vice versa. Unlike traditional heaters that convert 1.8kW of electricity to 1.8Kw of heat.

        The Difference is Air conditioners move heat energy(Look up specific heat of air).

        Heaters convert electric energy

        This is why its a lot cheaper to heat with an Air conditioner than a traditional heater. Infact its even cheaper to use the air con than gas heating during off peak hours.

        mick01 on 18/09/2012 - 19:00

        @dy4me It's pretty simple maths… 15A x 240v = 3600w, so TonyP is correct in that respect

      • 

        [Deactivated] on 18/09/2012 - 19:06

        Sigh. I'd love you guys to press the 'specifications' tab on the Bing Lee link for the air conditioner. It states - Current rating amps : 15 amps.

        That's 3600W.

        Can someone please back me and admit that this thing uses a crapload of power, and stop giving lessons on cooling capacity vs current draw?

        The 15A rating would just mean you need to place the unit on a 15A circuit (or higher). Probably to satisfy current draw on compressor startup. There is no way an air con unit with an output of 3.5Kw will draw anywhere near 15A continuous.

        Most electricians will place an A/C unit on its own 20A circuit if possible.

        Reminds me of an exchange I got into with the writer of this article in which the (still uncorrected) figures relating to air con energy use were also off by a factor of three or more, and the journo refused to comprehend his error.

        "The thrust of the story is correct" came his reply. Next time I get an AC installed, I'll be sure to give them $200 instead of the $600 quoted and, if they question it, insist that the thrust of my payment is correct. Or that it's still a crapload of money, so what's the big deal?

        pmupsinep on 18/09/2012 - 19:36

        Doze is 100% correct. Have a look at the other Kelvinator models, they are pretty much all rated at 10A, 15A or 20A. There's a 7kw unit that has a 15A rating too.

        It's the maximum draw current rounded up to the nearest common circuit current rating, to ensure electricians install the unit with an appropriately rated circuit.

        It is not accurate to determine what the actual current draw would be for the system running at full capacity.

        @TonyP @Mick01. All air con have to have an A rating. that to ensure they dont burn the wire or source of power. 15A is what Kelvinator says is safe for this Air con. Normal domestic power lines come as 10A 15A and some times 20A. Kelvinator isnt saying it uses 15A. its just safe on a 15A line as it wont draw any more than 15A. What you really want from Kelvinator is the Power watt rating. Like i said before, my 5.5kw aircon uses 1.8kw. If you do your match right thats 7.5A. Thats right. even though its rated at 5.5kw it uses 7.5A. yet its connected to a 15A line. thats cuz when you turn it on the Amps spike above 10A. so a 15A line is necessary.

      • 

        doze on 18/09/2012 - 19:48

        I'm guessing here but a 3.5Kw would consume around 1200-1400 watts, depending on efficiency, while the compressor is running.

        There is only a brief spike in current draw (milliseconds lol) when the compressor starts, which would require the 15A rating for the circuit.

      No deal then. The cost of electricity will be more than buying an inverter to start with.

  Add $600 for installation,

  I bought a new Kelvinator window a/c for $250. Installation $100 (new glass.) Saving? Around $1000. Noisy? No! And for bedrooms (where I'm using it, noise can be an advantage as it blocks out background noise and helps you sleep. Also, window a/cs are not nec. much less inefficient than splits (when I researched it recently.)

  dy4me on 18/09/2012 - 18:55

  Ok any one know how much to install these? is not a back to back install. more like split unit——4meters—-outdoor unit. 2 rooms 2 units.

  • 

    [Deactivated] on 18/09/2012 - 19:09

    Allow about $750 for a standard install, more for non-standard. It's next to impossible to quote without seeing the layout.

    • 

      [Deactivated] on 18/09/2012 - 19:56

      $750? Ouch! Much better to get a window a/c unless noise is an issue. In fact my new box a/cs are quieter than the split system in my bedroom!

      • 

        dy4me on 18/09/2012 - 22:29

        try sticking a window unit in a strata building and see how much noise the body corp will make.

  TonyP you need to pull your head in. You are completely wrong, as several other posters have been trying to tell you politely - doze; pmupsinep; Jabba; mick01; dy4me.

  Power consumption is based on Power Input. In the case of the Kelvinator KSE53HRC 5.3Kw, the Power Input is 1.57kw (cooling) and 1.65kw (heating). If you still disbelieve please refer to the Australian Government website for the explanation of how energy costs are calculated (ie input power) and for the specific data on the KSE53HRC :

  http://reg.energyrating.gov.au/comparator/product_types/64/s…

  Before flaming people in future, please try and understand the subject matter before posting. And based on your inability to comprehend basic physics, I don't think you are in any position to be quoting members installation prices for AC units.

    Thank you for the link showing the actual current draw for the unit.

    It makes it difficult for the end user to determine actual running costs when retailers advertise goods with the line "Current rating amps: 15 amps", when the actual draw is a maximum 1.65 kW (for heating) - 6.9A - less than half the advertised 'current rating'.

    Why do retailers even list the current rating? It's confusing and misleading to the uneducated (people like me). That's for the electrician wiring the unit up to worry about - it has no place on the retailers website - unless it's accompanied by the units actual current draw, in my opinion.

    And for the record, I never 'flamed' anyone. I told 'Jabba the Hut' he was incorrect - which I will retract - but I'd hardly call that 'flaming'.

    Additionally, I understand 'basic physics' fine. Using a straw man argument to draw the conclusion that because I don't know the actual current draw for the unit that therefore I wouldn't know how much it costs to install is silly.

    My unit was installed just last year and the going rate was never under $700, from the 5 or so installers I called. I ended up paying $750 because the installer was more reliable than the others.

      Were you paying attention? were you reading? The reason they provide the 15 amps is so that you make sure you put it on a 15 amps circuit. If you dont you can blow the circuit, burn wires…! seriously man. its all there. just read!!!

      Well would you want to buy a 15A unit id you dont have a 15A line in ur house? its there so u can make an educated decision. The only problem i see with their listing is not mentioning the actual power watts used. The Amps should be mentioned as thats required… not just for the electrician.

        Are you suggesting that homes usually come wired with spare 15 amp lines, wired to the correct locations, ready for informed people to purchase the correct air conditioning units?

        That's just silly.

        Hardly anyone who buys one of these units is going to know (or care) how this unit gets wired, however a large proportion will care how much it costs to run.

        The 15 amp rating is needed by the electrician, and it's extremely important for him/her to know this, but my argument is that it's superfluous information to have this listed on the units specifications, while not listing the true current draw.

        After all, if the current draw was listed on the website, my cost of running calculation would have been correct, there wouldn't have been 20 odd replies, and no-ones panties would have got into a bunch over what is, after all, just a simple multiplication exercise.

        Rather than being fixated on V x A = W, if you'd taken the initial challenges to your remarks as an opportunity to question your own position (e.g. looked up how heat pumps work, checked specs for similar air cons for which input power is specified, taken mick's point about duty cycles on board), and said "d'oh, my cost estimate was way off because I overlooked some important variables", it would've been a pretty brief, fruitful exchange.

        Was a simple matter of garbage in, garbage out.

        I just read that Age article you mentioned. Wow. Confusing cooling kW with actual power consumption, listing watts instead of kW, and still coming up with massively wrong figures. It's unfortunate that the article is still published, uncorrected.

        I wouldn't want that to happen again, so here are revised running costs (although the deal is finished, this information is for archive purposes).

        These figures are based on a 50% duty cycle on cooling, for the Kelvinator KSE53HRC 5.3Kw model (1.57 kW actual power consumption).

        1.57 kW x 12 hours running time x $0.25 x 50% duty = $2.35 per day running costs.
