Radiator number calculation:
Family homes can be calculated at 45W-80W per square meter. When you buy a heater, multiplying the room area by the number of W per square meter is the amount of heat the room needs. After calculating the number of radiators, 10%-20% can be added to avoid heating the radiators. Taking a 20-square-meter room as an example: 20×45=900 The radiator to be purchased must reach 900W or more (W: room for heat).
