Built for sweeps who demand field-tested precision
Summak Spirejo version 2.1 incorporates improved stability optimizations specifically for older iOS devices, ensuring heating engineers using legacy hardware maintain full access to real-time physics calculations and fault diagnostics without performance degradation during critical on-site inspections.
Every tool a professional chimney sweep actually needs in the field
Instant draught calculations processing six independent pressure terms simultaneously. No server dependency—pure on-device computation delivering Draw, Marginal, or Spill verdicts with exact pascal margins in under one second.
Comprehensive catalogue covering tar glaze, oversize bore, blocked bore, cold external stack, and four additional common chimney malfunctions. Each fault profile includes symptoms, diagnostic tests, and remedy suggestions with predicted pascal improvements.
Observe smoke spillage, tar smell, sooting glass, or roaring? Tag symptoms on-site and the fault key instantly narrows diagnostic candidates, running you through targeted test procedures that confirm root causes.
Photo overlay visualization matches your client's chimney terminal against regulation height envelopes. Year-round spill risk analysis accounts for seasonal buoyancy variations and wind effects across all weather conditions.
Complete inspection documentation on-site with structured sweep cards. Generate client reports including draught readings, fault diagnoses, remedy recommendations, and compliance verification—all stored locally for instant PDF export.
Zero network requirements. All calculations, fault diagnostics, photo overlays, and report generation function entirely offline. Data remains private on your device—nothing transmitted, nothing cloud-dependent, nothing vulnerable to connectivity loss.
Precision engineering for professional heating engineers
Summak Spirejo operates as a completely self-contained diagnostic suite running natively on iOS devices. The integrated physics engine processes flue geometry inputs—bore diameter, stack height, terminal position, external wall exposure—against real-time environmental conditions to calculate buoyancy, friction, wind, and dynamic pressure terms.
Every calculation adheres to established thermodynamic principles governing chimney draught behavior. The fault diagnosis system cross-references observed symptoms against eight catalogued malfunction profiles, each documented with symptom clusters, confirmatory test procedures, and remedy effectiveness predictions measured in exact pascal improvements.
Terminal height compliance verification utilizes photo overlay technology, allowing sweeps to superimpose regulation envelopes directly onto client chimney photographs captured in-app. Year-round spill risk modeling accounts for seasonal temperature differentials and prevailing wind patterns specific to external stack configurations.
iOS version 2.1 ready for immediate installation. Offline diagnostics. Zero subscription fees.
