A 1500 watt portable heater uses 1.5 kilowatt hours (kWh) of electricity for every hour it is in operation. So, if you run the heater for 8 hours, it would consume 12 kWh of electricity.
Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
From the details this is probably a UK question. It would use 60 watt-hours of energy every hour, which is 0.06 kWh or units of electricity, and that would cost around 1p.
A 2000 Watt fire burning for an hour will consume 2 kilowatt-hours (kWh) of electricity. This is calculated by multiplying the power of the fire (2000 W or 2 kW) by the time it is burning (1 hour).
To calculate the cost of running a 2 kilowatt convector heater per hour, you need to know the electricity rate charged by your utility company. Let's assume the rate is $0.12 per kilowatt-hour. In this case, running a 2 kilowatt convector heater for an hour would cost $0.24 ($0.12 x 2).

1500 watt hours
1 MW is 1000 kilowatts, so in 1 Hour it will sell 1000 units (taking a unit as 1 kilowatt hour)
To convert from kilowatts (kW) to British Thermal Units (BTU) per hour, multiply by 3412. Therefore, a 5kW heater would produce 5 * 3412 = 17060 BTU per hour.
To calculate the cost of running a 2 kilowatt convector heater per hour, you need to know the electricity rate charged by your utility company. Let's assume the rate is $0.12 per kilowatt-hour. In this case, running a 2 kilowatt convector heater for an hour would cost $0.24 ($0.12 x 2).
A heater with a power rating of 80W will consume 0.08 kWh (80W = 0.08kW) of electricity in one hour. Multiplying this by the cost of electricity, which is 0.17.24p per kW, the heater would cost around 1.4p to run for an hour (0.08kW x 0.17.24p/kW).
To calculate the cost per hour for a 400W heater, you need to know the electricity rate per kilowatt-hour (kWh) charged by your utility company. For example, if the rate is $0.12 per kWh, a 400W heater would use 0.4 kWh per hour (since 400W = 0.4 kW). Multiplying 0.4 kWh by $0.12 gives you a cost of $0.048 per hour to run the 400W heater.

The unit of energy in an electricity bill is a kilowatt-hour, also known as a Unit. To calculate the energy in units, multiply the power in kilowatts by the time in hours.
