A very simple method of determining the total heating capacity required can be found by calculating the square footage of the room and then multiplying that by 10 watts to get a baseline wattage requirement. For example, if you are heating a 12ft x 12ft room, it is 144 square feet.
What size room does a 2000w radiator heat?
tr>
| room size (square feet with 8 foot ceiling) | watts (poor insulation) | watts (average insulation) |
|---|---|---|
| 180 square feet | 2250 | 2000 |
| 200 square feet | 2500 | 2000 |
| 220 square feet | 2750 | 2250 |
| 240 square feet | 3000 | 2400 |
How much heating output do I need for my room?
In general, the power required for an electric heater is calculated in watts. Wattage: Multiply the square footage by 10. For a 20ft by 20ft room, that’s 400 square feet, multiply by 10 to give 4,000 watts.
1500 watts is a lot for a radiator?
Most electric heaters use 1500 watts, but some are slightly lower or slightly higher. … Since 1,000 watts equals 1 kilowatt, your heater uses 1.5 kilowatts of power. However, your electricity bill is measured in kilowatt-hours, which is the amount of energy consumed when a 1-kilowatt appliance is powered on for one hour.
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.
