How much to run an 15kw a/c system

[get the gauges]

Try the LG one or ask Mitsi themselves. Space also have a cost calculator too

Hey thanks,
I used that and came up with a £1072 for 52 weeks of use. I looked up a mitsi 3phase 14.5 kw unit and found the nominal kw input to be 4.36.

What do you reckon, worked it out in my head to be 3k if the comp never stopped so a system that starts and stops as it should properly would be about that i reckon.

Thanks Steve
