After a report earlier this week claimed that Gwen Stefani was pregnant with twins, gossip debunking site Gossip Cop slammed the report and called it false.
Best Answer: A microwave oven putting out 900 watts consumes around 1500 watts. One unit of electricity is 1 kilowatt-hour, so a 1500 watt appliance will use 1.5 kWh or 1.5 units. Electricity is about 7p per unit, so it will cost around 11p to run it continuously for 1 hour.
A common wattage for space heaters is 1,500 watts. Apply the formula 1,500 x 24 Ã· 1,000 x $0.20 to determine the cost to run the space heater for a day. (Dividing by 1,000 changes watt hours to kilowatt hours.) In this case, it will cost $7.20 if it was running for 24 hours straight.ost per kilowatt hour will determine how much it costs to run an electric heater. All electric heaters run on the principle of turning electricity into heat. The most common way to do this is to power up a wire coil and then use a small built-in fan to blow the heat out of the heating enclosure.
