Reckon I'll get a power meter and see whats drawing it, it's either the fridge or the HWS.Don't trust wiring and labels they are usually wrong.
I've had random appliances on wrong circuits and all that. It seems sparkies just wire to whatever is closest to them haha.
At that power level you are looking at major appliances, heating/cooling, hot water, air con, ovens (lol?).
I'd start by trying the following:
- Switch all appliances off at the power point.
- Check all the hard wired appliances for timer settings.
Reckon I'll get a power meter and see whats drawing it, it's either the fridge or the HWS.
A fridge is about 100-250w max.
It has to be heating, cooling or HWS as its a timed load.
That efegy energy meter I linked has a small CT that can be clipped around the positive cable, it trends on the display and can be looked back at later.
You could clip it over the HWS positive and it will tell you what times its drawing load, what load and even how much it costs you a day.
Will have another look, cheers
most modern A/C units wont pull 10 amps unless its a larger ducted unit, the kW rating of an AC unit is indicated in KWr not KWe (kilowatts of refrigeration not electrical kW's)Post up a screenshot of the power usage graph.
As what other said, it’s a significant amount of power. Do you have a pump for the house/garden? Is someone turning on an air conditioner?

Yep I know about cooling/heating/electrical power ratings. Mine draws 6kW and its 3 phase so wouldn’t see it out of the question that a decent split system could draw 2.5kW
not exactly...have a look at a thing called COP, (Coefficient of Performance) as I said above, Kilowatts of electrical power is not the same thing as Kilowatts of refrigeration...Kilowatts is just a measurement of power consumption but there is different ways this is appliedMy single phase ducted draws 5.5kw cooling and heating.

have a look at the current rating of the unit and do the maths!
Actron and Daikin make monster single phase ducted unit up around 18 - 20 kW. It's possible.
Cheap Heat pump HWS are no good for areas that drop below 0°C,
only good in summer and mild temp areas, as the condensation on the evaporator coil will freeze in very low temps leaving you only the electric booster element with no real benefit of heat pump principleFIFY
A few of those off gridders in the US use heat pumps but layer the insulation. I saw one do the ground pipe thing. 8 or 10m underground. Temp stable at 17C year round. They had 3 months of freezing in the mountains in Montana ans pumping air around the circuit provided a big chunk of general heating.
