Hey! I'm a developer who also heats with wood. In Germany you need a chimney calculation per DIN EN 13384 before connecting a new stove. The official route is either expensive or slow. I wanted to know before buying a stove whether my chimney would work, so I built this.
The math behind it is gnarly (thermodynamics, fluid dynamics, iterative pressure/temperature solving along the flue path), but the UI tries to make it approachable. Pick your stove, describe your chimney, get a yes/no answer plus the full details if you want them.
Would love feedback on the UX. The target audience ranges from homeowners to chimney sweeps, which makes the complexity balance tricky.
