Ok, im gonna have a go at working out a price for my electrics.
Lets say,
2 x 400watts sodium (avg. 50 per 3 mnths)
2 x RVK125 A1 240m3/hour. I think these are about 35watt, but please correct me if im wrong.
If 1000wph (1 unit) costs around 6.8p
thats 0.0068 per watt? Am i on the right lines???
0.0068 * 35 (35watt fan) = 0.238
0.238 * 24 hours = 5.712p per day??
5.712 * 30 days = 171.36p per month
171.36 * 3 = 514.08p per three mnths, per one fan
2x for 2 fans = 1028.16
I make that about 110 quid every three months??
Any advance???
