  Hey, I'm after the lowest cost >3kwh air con out there. any recommendations?

  When you say, '3kwh' what do you mean exactly? 3kwh is a measure of an aggregate amount of energy, rather than the 'power' of an air conditioner, which would be measured in kw, and when run for a period of time, would consume an amount of energy:

  kw multiplied by time (hours) = kwh

  A 1kw unit run for 3 hours would consume 3kwh of energy
  A 2kw unit run for 90 mins would consume 3kwh of energy
  A 100W light bulb run for 30 hours would consume 3,000 watt hours (3kwh) of energy

  Any appliance running at more than 2.4kw (2,400 watts) should not be run from a standard ring-main in NZ, as they are generally limited to 10 Amps, else a fuse could blow. Power is Voltage multiple by Current, and mains voltage in NZ is around 230V (230V +/- 6% I think, but I'd have to check to be sure, which would mean a low of about 216V and up to about 244V).

  An appliance receiving 240V and drawing 10A would run at 2,400 watts (2.4kw), which should be about the limit of anything sold in NZ to 'plug in'.

  If you meant 3kw (rather than 3kwh) then it would require installation by an appropriately qualified electrician in which case, I would suggest contacting various installers around you and asking for quotes.

  Personally, I would be cautious about purchasing a unit that required installation, and then contracting someone to do the installation, as it could leave a 'gap' for the vendor and installer to blame the equipment / installation if something was not working properly. If you get someone to supply and install, it is fairly unambiguous that they are responsible to you.

  HTH,

  Alan.

      Okay - That's the same as you put in your OP, but it doesn't make any sense.

      I suspect you mean 3kw (which is at the low end I think), but I suggest you read around the subject a little to better understand, or maybe best to just get installers to come in and do it all for you (including suggested specs) as part of quoting.

      Good luck!

  You will have calculated what size heatpump will be suitable for you

  I installed midea heatpump in our house we brought. It cost me about 640 NZD each for a 2 kw max heat out unit
  And a 7kw max heat out unit for 1k NZD .

  They are decent for price

  If you want the best them Daikin is what you should consider. Next best option will be ME AND mhi

  General rule of thumb you can go size smaller but can't go size up as ihp can not regulate temperature Better

    Cheers how much did the installation cost you? I've been quoted 1500 + gst for a midea install
