Let's see... 1850KW at 240 volts means your heat
pump circuit must be good for at least 7710 amps.
Obviously that's not the case, so you must have a
hell of a high voltage line coming to your house!

I think you are calculating the wrong way or something. 10 amp is
enough to run a 2000W space heater with some to spare.
I am not realy into electricity works, but I think 10 amps equals 2400
watts.
Anyhow, the heatpump is made to be used with 240V and a 10amp fuse.
Maybe we got magic fuses here in Norway, what do I know?

He was joking because you mistyped the KW,
that made it 1,85 megawatts. :-)

Aha.:-)
I tend to forget that cap is important even when there are no
computers involved..:-)
Guess it should be kW then. (He wrote somewhat uncertain.)

Uhhhhh.......It's all in the dot!!!!!!
1850kW = 1.85MW
1850W = 1.85kW
1.850kW = 1850W
It should of been 1.850kW, 1.850KW or 1850W
