1. What is a Boiler Size Calculator for House?

Definition: This calculator estimates the required boiler size in kilowatts (kW) based on the square footage of your house.

Purpose: It helps homeowners and heating professionals determine the appropriate boiler capacity for efficient home heating.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Size (kW)} = \frac{\text{Sq Ft} \times 50}{3412} \]

Where:

50 — Represents the approximate BTU per square foot needed for heating
3412 — Conversion factor from BTU to kW (1 kW = 3412 BTU)

Explanation: The formula calculates the required heating capacity by multiplying the area by typical heating needs and converting to kW.

3. Importance of Proper Boiler Sizing

Details: Correct boiler sizing ensures efficient operation, prevents energy waste, and maintains comfortable indoor temperatures.

4. Using the Calculator

Tips: Enter your home's total square footage. The calculator will determine the recommended boiler size in kilowatts.
