1. What is a Heat Pump Cost Calculator?

Definition: This calculator estimates the total cost of a heat pump installation in the UK based on base installation costs and size-dependent factors.

Purpose: It helps homeowners and contractors budget for heat pump installations by providing a quick cost estimate.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Cost = Base + (Size \times Factor) \]

Where:

\( Cost \) — Total installation cost (£)
\( Base \) — Fixed installation costs (£)
\( Size \) — Heat pump capacity (kW)
\( Factor \) — Cost per kW (£/kW)

Explanation: The total cost combines a fixed base cost with a variable cost that depends on the heat pump's size.

3. Importance of Heat Pump Cost Calculation

Details: Accurate cost estimation helps in budgeting, comparing different systems, and applying for government grants or financing.

4. Using the Calculator

Tips: Enter the base cost (default £1500), heat pump size in kW, and cost factor (default £500/kW). All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What's included in the base cost?
A: The base cost typically includes installation labor, basic materials, and standard components.

Q2: How do I determine my needed heat pump size?
A: A professional heat loss calculation is recommended, but roughly 0.04-0.06 kW per m³ of your home's volume.

Q3: Why does cost increase with size?
A: Larger units require more materials, higher capacity components, and sometimes more complex installation.

Q4: Are there government grants available?
A: Yes, check the UK's Boiler Upgrade Scheme (BUS) which offers £7,500 towards air source heat pump installations.

Q5: Does this include VAT?
A: No, add 5% VAT for residential installations or 20% for commercial properties to the calculated cost.
