look at elec bill to determine peak rate per hour (prob around 22c).
times rate by 2.4
this value is how much it will cost you to run each hour if it runs whole time (ie thermostat doesn't turn it off during this time).


If you look at the brochure on the Thermofilm website, they calculate 23c/hour for the 2400W model (* based on normally insulated rooms with standard ceiling height. Running costs are based on 16 cents/kw hour electric tariff, and 60% operating cycle after a warm up period. ) I think Tariffs are generally higher than that now.
Thanks HotI. Is that expensive? I have no clue We have only been in this place 4 weeks so I am testing out how everything works.
