1. What Is BTU For Heating Radiators?

BTU (British Thermal Unit) measures heating capacity required to effectively warm a room. Proper BTU calculation ensures your radiator provides adequate heat without energy waste.

2. How Does The Calculator Work?

The calculator uses the standard BTU calculation formula:

Where:

• \( Room\ Volume \) — Volume of the room in cubic meters
• \( Insulation\ Factor \) — 25-35 depending on insulation quality

Explanation: Rooms with poor insulation require higher BTU (×35), average insulation requires ×30, and well-insulated rooms require ×25.

3. Importance Of Proper BTU Calculation

Details: Correct BTU calculation ensures efficient heating, prevents energy waste, maintains comfortable room temperature, and extends radiator lifespan.

4. Using The Calculator

Tips: Measure room volume accurately (length × width × height), select appropriate insulation level based on your room's characteristics for optimal results.

5. Frequently Asked Questions (FAQ)

Q1: What happens if BTU is too high?
A: Oversized radiators cycle on/off frequently, wasting energy and creating temperature fluctuations.

Q2: What if BTU is too low?
A: Undersized radiators run continuously, struggle to heat the room, and increase energy costs.

Q3: How do I measure room volume?
A: Multiply room length × width × height in meters to get cubic meters (m³).

Q4: What affects insulation factor?
A: Window quality, wall insulation, ceiling insulation, and room exposure to external elements.

Q5: Should I add extra BTU for windows?
A: Large windows or poor-quality windows may require additional BTU capacity, typically 10-20% extra.
