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.
For this situation, using average residential electricity costs, the monthly cost to run the HRV/ERV would be approximately $12. The average power draw of an HRV/ERV is 150 watts. If it runs 24 hours a day for 30 days each month, then the monthly energy consumption would be. 150 W Ã 24 hrs./day Ã 30 days/mo.
