There's also one that's "7000 BTU/hour" but, obviously, has less cooling power.

I've found this, to work out running costs;

Watts = Btu/hour x 0.293

So... the 7000 one uses 2051 Watts, and the 9000 one uses 2637 Watts... it sounds expensive?

My parents foot the bill, so I have no idea how much this is going to cost in electricity? I can't just go out and buy one if it's going to cost them a fortune to run

So based on the wattage, how do I know how much this will cost to run? 2,600 Watts does sound a lot - but I have no idea on the value of electricity! What do you reckon?

Cheers
