BTU Calculation Formula:
| From: | To: |
BTU (British Thermal Unit) is a unit of heat energy. One BTU represents the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. In heating applications, BTU is used to measure the heating capacity of heaters and furnaces.
The calculator uses the BTU calculation formula:
Where:
Explanation: This formula calculates the BTU requirement based on the volume of space to be heated and the desired temperature increase.
Details: Proper heater sizing is crucial for energy efficiency and comfort. An undersized heater will struggle to maintain temperature, while an oversized heater will cycle on and off frequently, reducing efficiency and comfort.
Tips: Measure room dimensions to calculate volume (Length × Width × Height). Determine the temperature difference between desired indoor temperature and average outdoor temperature during heating season.
Q1: How do I calculate room volume?
A: Measure length, width, and height in feet, then multiply: Length × Width × Height = Volume in cubic feet.
Q2: What temperature difference should I use?
A: Use the difference between your desired indoor temperature and the average outdoor temperature during heating season. For example, 70°F indoor and 30°F outdoor = 40°F ΔT.
Q3: Are there other factors to consider?
A: Yes, consider insulation quality, window area, ceiling height, and climate zone. This calculator provides a basic estimate.
Q4: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, use the actual cubic footage. High ceilings require more heating capacity.
Q5: Should I add extra capacity?
A: It's generally recommended to add 10-20% extra capacity for particularly cold climates or poorly insulated spaces.
