Heating Cost Formula:
From: | To: |
Definition: This calculator estimates the total cost of radiant floor heating including installation and operational electricity costs.
Purpose: It helps homeowners and contractors budget for radiant floor heating systems by calculating both upfront and ongoing costs.
The calculator uses the formula:
Where:
Explanation: The formula combines the fixed installation cost with the variable electricity cost (converted from Watts to kW).
Details: Accurate cost estimation helps in budgeting, comparing heating options, and understanding long-term operational expenses.
Tips: Enter the installation cost, system power in Watts, estimated operating hours, and local electricity price (default 0.12 currency/kWh). All values must be ≥ 0.
Q1: What's included in installation cost?
A: This includes materials (heating elements, insulation, flooring) and labor costs for the complete system installation.
Q2: How do I find my system's power rating?
A: Check manufacturer specifications - typically 10-15 Watts per square foot depending on system type.
Q3: What's a realistic operating hours estimate?
A: For whole-house heating, estimate 8-12 hours/day in winter. For bathroom-only, 1-2 hours/day may suffice.
Q4: Why divide by 1000 in the formula?
A: This converts Watts to kilowatts (1 kW = 1000W) to match the kWh electricity billing unit.
Q5: Does this include maintenance costs?
A: No, radiant floor systems have minimal maintenance, but you may want to add 1-2% annually for potential repairs.
