How many watts is 2.2Kva?

Answer 1

Kva is approximately equatable to Kilowatts.

So for 2.2Kva in a domestic setting you can say it is 2.2Kilowatts or 2200 watts.

The reason it is approximate is that, this translation does not take account of power factor (PF),

which becomes a serious problem if you are running many motors or fluorescent lights

(usually seen in offices, looks like a tube) at the same time. This does not effect things that only heat things up, example: immersion heaters or your cooker.

In your house you have very few large motors, 1 in washing machine, 1 in tumble dryer (and these generally won't be on at the same time), and you probably have very few fluorescent lights, as such you don't really need to consider the power factor. However if you did want to work it out then the Watts always goes up.
In which case 2.2 Kva would generally translate as closer to 2300 watts. or somewhere between 1% and 10%. Please remember only for motors and fluorescent. Also some chargers for phones laptops etc, but these devices generally use way less Kva/KW and so the difference is negligible.


If you are interested, a detailed explanation of Power Factor can be found on elsewhere on the web, however this is not light reading unless you have some electrical/science background.
