Lenny,
I appreciate the time you have taken to produce this list but many of the figures for electricity are a nonsense. Electrical appliances can obviously vary tremendously, however many of the examples in the list give way higher consumption than 'typical'. A few examples:

1. Most lap top computers have a consumption around 25-30watts so 30 to 40 hours on 1kWh not 1.5 hours.
2. PC with monitor 6-8 hours not 1.5 hours would be typical.
3. Even the maximum rated tumble dryer(3kW) cannot use 4kW in an hour - even in the unlikely event of it being on maximum heat for an hour.
4. The consumption for washing machine, fridge freezer, fridge dishwasher quoted above are several times higher than my appliances.
5. Some of the appliances might use the consumption quoted if they were not on a thermostat.

Hi Lenny.

With 2 large ponds and a large tropical tank i can see why my bills are high

Thanks for the info though,i have often wondered about appliances.

If you know the wattage then
kwh per hour of use is wattage / 1000.
Eg: 100 W light bulb is 0.1Kwh per hour, or 10 hours for 1 unit.
