How big a room can be heated with a 2kW radiator?

Let’s call it 20m² for the sake of simplicity. That is, if it is a living space, you need 2 kW to heat it. If it’s a bedroom, 1.5 kW will probably be enough.

How much does it cost to run a 1500 watt heater for 24 hours?

A common wattage for heaters is 1500 watts. Apply the formula 1500 x 24 ÷ 1000 x $0.20 to determine the cost of running the heater for one day. (Division by 1000 changes watt-hours to kilowatt-hours.) In this case, running 24 hours straight would cost $7.20.

How big is a room with 1500 watt heating capacity?

Typically, you need about 10 watts of heating power for every square foot of floor space in the room. This means a 1500 watt heater can be the primary heat source for an area up to 150 square feet.
