Ceramic Costs?? Cant figure it out.. Thanks

[simon07989]

When trying to work out electricity costs for a 250 watt Ceramic Bulb on a Pulse Stat, how many hours per day should I put down as usage.

With a Heat Mat I can guess that with it turning on and off it will run for around 20 hours a day ON.

Any ideas on the Ceramic on a Pulse Stat?

Or, costs to run a 250 Watt Ceramic per week/month?

Thanks,

Simon
