## What is BrennerCalc?

BrennerCalc brings together calculation aids for heating and HVAC service. Use the existing burner, nozzle, gas and heating-water calculators and document the inputs behind your work.

INSTALLATIONS AND SERVICE VISITS
Name installations and capture dated visits as fixed calculation snapshots. Record input sources and visit notes. Reopen saved results without changing them when you make new calculations.

BEFORE-AND-AFTER COMPARISON
Compare compatible visits of the same calculation type. Share a service record with inputs, sources, notes, results and clear differences.

German and English. Local calculations and service records work offline. The oil-burner calculators are free. BrennerCalc Pro permanently unlocks the gas and heating-water calculators with a one-time in-app purchase. Existing Pro unlocks remain available.

Professional calculation aid: manufacturer data, applicable rules, system design and actual measurements take precedence. Check results against the real installation.
