4 kilowatt.hours, that is 4 x 3600 kilowatt.seconds. 1 kilowatt.second = 1 kilojoule, so the total in 1 hour is 14,400 Kilojoules. You can also put this as BTU if you want, 1 kilojoule = 0.9478 BTU, so your heat in 1 hour is 13,648 BTU.

2000 watts is also known as 2 kW. In one hours this heater uses 2 kWh, in ten hours it would use ten times as much, 20 kWh. The energy used is found by multiplying the power by the number of hours.
