How it works?

1. Heated Floor Area

Enter the total area you intend to heat in square feet. This could be the area of a single room or the entire house.

2. Insulation Type

Select the insulation type of your home. This factor influences the design power density and, consequently, the heating requirements.

Examples:

  • High-Performance Home:

    • Characteristics: Well-insulated walls, high-quality windows, and efficient doors.
    • Selection: Choose this option if your home is modern, well-insulated, and energy-efficient.

  • Average Home:

    • Characteristics: Standard insulation in walls, windows, and doors.
    • Selection: Opt for this if your home has typical insulation levels found in many residential buildings.

  • Poorly Insulated Home:

    • Characteristics: Limited insulation in walls, windows, and doors.
    • Selection: If your home is older or lacks proper insulation, this option reflects a less energy-efficient scenario.

3. Floor Type

Choose the type of flooring in the heated area. Different materials have varying thermal conductivity, affecting the heating needs.

Examples:

  • Tile:

    • Characteristics: Excellent heat conductivity, suitable for efficient heat distribution.
    • Selection: Ideal for areas where quick heating and even distribution are priorities.

  • Wood:

    • Characteristics: Moderate heat conductivity, may require slightly more power for efficient heating.
    • Selection: Suitable for those who prefer the aesthetic of wood flooring but may need a bit more heating power.

  • Carpet:

    • Characteristics: Lower heat conductivity, may require more power for efficient heating.
    • Selection: A good option for bedrooms or areas where the comfort of a carpeted floor is preferred.

  • Stone:

    • Characteristics: High thermal mass, may require more power for efficient heating.
    • Selection: Commonly used in high-end designs; be mindful of the potential need for additional heating power.

4. Operating Hours and Days

Input the average number of hours per day and the number of days per year you plan to operate the underfloor heating system.

5. Cost per Kilowatt-Hour

Specify the cost of electricity per kilowatt-hour in your region. This is essential for calculating the overall running cost.

6. Click “Calculate”

Once you’ve provided the necessary information, click the “Calculate” button to get an estimate of the running cost of your underfloor heating system.

Limitations

While this calculator provides a useful estimate, it’s essential to consider some limitations:

  • Assumptions: The calculation assumes average conditions and may not account for specific variations in your home.

  • Estimations: The running cost is an estimation based on design power density, consumption reduction, and electricity cost. Actual costs may vary.

  • Flooring Material Impact: The calculator incorporates different multipliers for flooring types, but real-world conditions may vary.

  • Energy Price Fluctuations: Electricity prices can change, impacting the accuracy of long-term cost estimates.
