Hi everyone, I'm hoping someone may be able to confirm my workings out.
I am trying to work out the energy consumption per hour of a cellar cooling system using OHM'S law, the manufacturers data and current energy prices (£0.34kwh).
According to the manufacturer the complete system draws 9.7amp.
Using OHM'S law 9.7amp x 230v = 2231w (2.231kw)
2.231/3600 x 3600 = 2.231 x 0.34 = £0.75.
So by my working out the customer is paying on average £0.75 per hour to run their cellar cooler. I appreciate that the amp draw is dependent on the system charge being correct, clean coils etc, i'm just hoping to give them a ball park figure and can the then explain all the variables in play.

Does this sound about right or am I being a complete pleb.

Many thanks in advance.

(For reference the system is a Marstair CX50+ CKC50 running R407c)
