1. What is a Radiator Output Calculator?

Definition: This calculator converts a radiator's BTU/h rating to kilowatts (kW) output.

Purpose: It helps HVAC professionals and homeowners understand radiator power output in different measurement units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P_{kW} = \frac{Q_{btu}}{3412} \]

Where:

Explanation: 3412 BTU/h equals 1 kW, so dividing the BTU rating by this conversion factor gives the equivalent power in kW.

3. Importance of Radiator Output Calculation

Details: Understanding radiator output in kW helps with energy efficiency calculations, system sizing, and comparing different heating systems.

4. Using the Calculator

Tips: Enter the radiator's BTU/h rating (found on the product label or specifications). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert BTU/h to kW?
A: kW is the standard unit for power in most countries outside the US, making it easier for international comparisons and calculations.

Q2: What's the typical output range for home radiators?
A: Residential radiators typically range from 1,000-10,000 BTU/h (0.3-2.9 kW).

Q3: Is this calculation accurate for all radiator types?
A: Yes, the conversion applies to all radiator types as it's simply a unit conversion, not dependent on design.

Q4: How do I find my radiator's BTU rating?
A: Check the product label, manufacturer specifications, or measure the radiator's physical dimensions and consult sizing charts.

Q5: Does this account for efficiency losses?
A: No, this is a direct unit conversion. Actual delivered heat may be slightly less due to system inefficiencies.
