Heat Pump Annual Electricity & Cost

Estimate annual electricity and cost from delivered heat, SCOP and electricity price.

Updated September 2026

How it works

Estimate annual electricity and cost from delivered heat, SCOP and electricity price.

Formula:
Electricity = delivered heat / SCOP; annual cost = electricity·price.
Before you use the result: Use a project-relevant seasonal performance value; SCOP depends on climate, temperatures and system design.

Practical use

Use verified material data and project geometry. Treat results as planning estimates and compare them with the energy/thermal requirements that apply to the project.

  • Keep units consistent with the source information.
  • Use project-specific densities, pack sizes and coverage rates where provided.
  • Round purchasing quantities to supplier packaging and delivery rules.

How to use this calculator: Heat Pump Annual Electricity & Cost

Estimate annual electricity and cost from delivered heat, SCOP and electricity price.

Quick workflow

  1. Enter the project values from the latest drawing, specification or verified site measurement.
  2. Check units, material properties, allowances and any code- or supplier-specific parameters before calculating.
  3. Review the result together with the formula, assumptions and the related checks shown on this page.

Worked example

Example inputs: Annual delivered heat [kWh/year]: 18 000; Seasonal COP / SCOP: 3.8; Electricity price [currency/kWh]: 0.3.

Using the sample values built into the calculator, the calculation gives approximately: Annual heat pump electricity: 4 737 kWh/year; Annual heat pump cost: 1 421 currency/year.

What the result means

Calculation method: Electricity = delivered heat / SCOP; annual cost = electricity·price.

Before using the result: Use a project-relevant seasonal performance value; SCOP depends on climate, temperatures and system design.

Common questions

What does this calculator do?

Estimate annual electricity and cost from delivered heat, SCOP and electricity price.

Which inputs should I verify?

Key inputs to verify include: Annual delivered heat [kWh/year], Seasonal COP / SCOP, Electricity price [currency/kWh].

Can I use this result for final design or ordering?

Use the result as a transparent planning or checking aid. Final design, code compliance, supplier selection and project-specific decisions still need to be verified where applicable. Use a project-relevant seasonal performance value; SCOP depends on climate, temperatures and system design.
