Compressed Air Heat Recovery Calculator

Estimate recoverable heat value from entered compressor energy and usable heat fraction.

Project inputs

Change the assumptions to explore an early planning scenario.

Planning result

Enter your assumptions

  • Potential useful heat
  • Annual avoided heating cost
  • Project cost
  • Simple payback

How to use this result

Use this as an early opportunity screen before engineering airflow, temperatures and seasonal heat demand.

Coincidence matters

Recovered heat only has value when there is a useful demand at the same time.

Ventilation and safety

Do not compromise compressor cooling, air quality or equipment clearances.

Important: Costs, codes, permits, inspection duties, accessibility rules, environmental requirements and insurance conditions vary by country, province or state, municipality, building use, equipment type, installation date and project scope. Qualified local professionals and the authority having jurisdiction must determine what applies. Compressed air stores substantial energy. Pressure vessels, piping, hoses, electrical equipment, hot surfaces, noise, condensate, moving machinery and inappropriate cleaning practices can cause serious injury or property damage. The site does not select compressor capacity, pressure, receiver volume, relief devices, piping materials, breathing-air treatment, lockout procedures or inspection requirements. Use qualified professionals, equipment manuals and the rules that apply at the facility.
