1. What is an Electric Underfloor Heating Cost Calculator?

Definition: This calculator estimates the running cost of electric underfloor heating systems based on area, power density, operating hours, and electricity price.

Purpose: It helps homeowners and contractors estimate the operational expenses of electric underfloor heating installations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Cost — Total running cost (currency)
• Area — Floor area (square meters)
• Power Density — Heating system power per unit area (W/m²)
• Hours — Operating time (hours)
• Electricity Price — Cost per kilowatt-hour (currency/kWh)

Explanation: The formula calculates total energy consumption in kWh, then multiplies by electricity price to get total cost.

3. Importance of Cost Calculation

Details: Accurate cost estimation helps in budgeting, comparing heating systems, and optimizing usage patterns for energy savings.

4. Using the Calculator

Tips: Enter the floor area in m², power density (default 150 W/m²), operating hours, and local electricity price (default 0.15 currency/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical power density for underfloor heating?
A: Most systems range between 100-200 W/m², with 150 W/m² being common for residential applications.

Q2: How do I find my electricity price?
A: Check your utility bill for the cost per kilowatt-hour (kWh) in your local currency.

Q3: Does this include installation costs?
A: No, this only calculates operational/running costs based on electricity consumption.

Q4: How accurate is this estimate?
A: It provides a theoretical maximum. Actual costs may be lower due to thermostat control and heat retention.

Q5: Can I use this for water-based underfloor heating?
A: No, this calculator is specifically for electric systems. Water-based systems have different calculation methods.
