HVAC calculations and designs in the AI era
AI reads the building documents and prefills your project data. The calculations are always done by the algorithm - per PN-EN 12831-1.
How you work with HeatAlgo
Your work in three steps
First you collect the data, then you calculate, then you design.
No more chasing data by phone
You send the client a form link or paste their documents yourself - AI reads the data, and you review and approve the full set.
Calculate to the standard
OZC per PN-EN 12831-1 (ISO 6946, ISO 13370) - room by room, following the standard's full procedure.
Design the underfloor heating
You draw the zones on the floor plan, and HeatAlgo works out the pipe spacing, loops and flows - and shows instantly whether the underfloor heating covers the heat loss. An execution-ready PDF with your logo.
Modules
Every calculation and design in one account
HeatAlgo is a browser-based program for installers: OZC heat-loss calculations per PN-EN 12831-1, underfloor heating design on the floor plan and preliminary heat pump sizing - plus AI that reads data from the building documents: through a form sent to the client or documents you paste yourself.
Heat loss calculations
PN-EN 12831-1 with no shortcuts. A partition library, thermal bridges per Annex B, and results that feed the other modules.

For 33 years I worked all this out more slowly. Now client data arrives on its own, and I get OZC and the underfloor heating design done in one afternoon.

How is HeatAlgo different from traditional calculation software?
It goes further: AI collects the calculation data for you - you send the client a form or paste their documents yourself, and you review and approve the proposed values before they enter OZC. On top of that, everything runs in the browser - no installation, no training.
