Hi Product Hunt 👋 This started in a Facebook group. We found a community of heating installers and what struck us was how frustrated they were with the software they're supposed to use every day. The same three complaints came up over and over: the programs are too complicated, you have to download and install them on a PC, and the learning curve is brutal - there's a real gap between opening the thing and getting a usable result out of it. So we built Heatalgo for the people in that group. What we're launching today: you upload a floor plan and it lays out the underfloor heating. Rooms come back identified, heating sections generated — spiral, meander or bifilar — and sized against PN-EN 12831-1. You review it, correct anything it got wrong by saying what's wrong in plain language, and commit the version you picked. It never applies anything on its own. And it runs in a browser. Being straight about what's underneath, because "AI does your engineering" is usually a lie: the model reads the drawing. The physics is a deterministic engine. Rooms it isn't confident about get drawn and flagged rather than quietly dropped. First generation is free, Google sign-in, no card. There's a 3-minute walkthrough if you'd rather watch than sign up. Curious whether anyone here has built for a trade like this one - sitting in a Facebook group reading what people complain about turned out to be the most useful thing we did. Happy to answer anything.
