不过我实际上可以降低购买baseboard heater 所需的瓦数。
Manufacturer's Recommended Heating Needs
It is always best to slightly oversize when selecting baseboard heaters. There is no loss of efficiency by heating your space with baseboard heaters that are slightly larger than the minimum requirements.
For example, a 30-amp circuit can accommodate a baseboard heater rated for 500 square feet or 4,500 watts, but the same heater will be more efficient at heating a smaller room (assuming the circuit size is appropriate). It's also possible to put two or more baseboard heaters on the same electrical circuit as long as their total combined wattage is not higher than the circuit's maximum capacity.
Total Area of Room (sq. ft.) | Recommended Heater Rating (watts) | Electrical Circuit Size Needed (240 volts) |
---|---|---|
100 | 900 | 15 amps |
150 | 1350 | 15 amps |
200 | 1800 | 15 amps |
300 | 2700 | 15 amps |
400 | 3600 | 20 amps |
500 | 4500 | 30 amps |
800 | 7200 | 40 amps |
1000 | 9000 | 50 amps |
