1. What is a Heat Pump Savings Calculator UK?

Definition: This calculator estimates potential savings when switching from gas heating to a heat pump system in the UK.

Purpose: It helps homeowners and businesses evaluate the financial benefits of adopting heat pump technology.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Savings — Potential annual savings in pounds
• Gas Bill — Current annual gas heating costs (£)
• Electricity Bill for HP — Estimated annual electricity costs for heat pump (£)
• Factor — Adjustment factor (typically 1.0 for direct comparison)

Explanation: The difference between current gas costs and projected electricity costs is multiplied by a factor to account for efficiency differences.

3. Importance of Heat Pump Savings Calculation

Details: Accurate savings estimation helps justify the investment in heat pump technology and supports energy transition decisions.

4. Using the Calculator

Tips: Enter your current annual gas bill, estimated heat pump electricity costs, and adjustment factor (default 1.0). All values must be ≥ 0 (factor > 0).

5. Frequently Asked Questions (FAQ)

Q1: What does the factor represent?
A: The factor accounts for system efficiency differences, seasonal variations, and potential government incentives.

Q2: How do I estimate my heat pump electricity costs?
A: Multiply your current gas usage (in kWh) by the heat pump's COP (Coefficient of Performance), then by electricity rates.

Q3: What's a typical factor value?
A: Start with 1.0 for direct comparison. Adjust up for high-efficiency systems or down for older heat pumps.

Q4: Does this include installation costs?
A: No, this calculates operational savings only. Consider payback period separately.

Q5: How accurate are these estimates?
A: Estimates are approximate. Actual savings depend on insulation, climate, system efficiency, and energy prices.
