Air Source Heat Pump Calculator

What is the Air Source Heat Pump Calculator – Savings and Payback?

The Air Source Heat Pump Calculator estimates the annual savings and payback time of an ASHP compared to the current heating method. The COP (coefficient of performance) of an air source heat pump is typically 2.5–4.0, meaning that one kilowatt-hour of electricity produces 2.5–4 kWh of heat.

The calculator is free, works in the browser, and does not require registration. This site has over 200 calculators with up-to-date data.

Calculation Principle

Savings/v = Current heating costs − (Heating demand ÷ COP × electricity price)

Fill in your information in the fields and press the calculate button – the result will appear immediately. Try different values to compare various options.

Practical Example

Direct electric heating $4,000/year. ASHP COP 3.0, electricity $0.15/kWh → new costs 4000×0.15÷(0.18×3) ≈ $2,000/year. Savings $2,000/year. Purchase price $1,500 → payback in less than 1 year.

Enter your own information into the calculator to get a personalized result. The calculator is suitable for both quick comparisons and more detailed planning.

Who is the calculator intended for?

The calculator is designed for individuals, entrepreneurs, and professionals. All calculators on this site are free of charge.

For important financial or legal decisions, we recommend verifying the figures with official sources or an expert.

Tips

• Install the ASHP on the south wall of the living room – it is usually the coldest and largest room in the house.
• Clean the filters 2–4 times a year to maintain efficiency.
• Compare installation companies – the price difference can be hundreds of euros for the same device.
