Heater Size Calculator
Choosing the Right Heater for Your Space
Selecting the appropriate heater size is crucial for maintaining a comfortable indoor environment while optimizing energy efficiency. The size of a heater, measured in watts or BTUs (British Thermal Units), depends on factors such as room dimensions, insulation quality, outdoor temperature, and desired indoor temperature. This calculator simplifies the process by providing accurate estimates tailored to your specific needs.
Factors Affecting Heater Size
- Room Size: Larger rooms require more heating power. The calculator uses length, width, and height to compute the room’s volume, a key factor in determining heater size.
- Insulation Quality: Poorly insulated spaces lose heat faster, requiring a more powerful heater. Options include poor, average, and good insulation levels.
- Temperature Difference: The greater the difference between outdoor and desired indoor temperatures, the more heating power is needed.
- Windows: Windows contribute to heat loss. Entering the total window area helps refine the calculation.
- Energy Costs: By inputting your electricity cost and daily usage, you can estimate daily and monthly heating expenses.
How to Use This Calculator
Follow these steps to determine the ideal heater size for your space:
- Select your preferred unit system: Metric (meters, °C, watts) or Imperial (feet, °F, BTUs).
- Enter the room’s dimensions (length, width, height) and select the insulation quality.
- Input the outdoor temperature and your desired indoor temperature.
- Optionally, provide the total window area and electricity cost for more detailed results.
- Click "Calculate" to view the required heater power, energy costs, and a cost trend chart.
- Use "Save Inputs" to store your data and "Load Saved Inputs" to retrieve them later.
