What it costs
TermoFlo is free right now: the product has no checkout, so there is nothing to pay for and nothing to pay with. Below is what is available today, not what we plan to sell.
Available now
- All four calculators, with no tier restriction
- The material library and city climate data
- Calculation history, kept with no time limit
- Saved wall assemblies
- Thermal calculation export as a document
- A monthly calculation allowance for registered users; a guest session has a smaller one
We do not state the exact number here: it currently differs between the code and the documentation, and stating it would repeat what this page has just stopped doing.
What will be paid
While there is no checkout we do not list future plans here — a promise that cannot be kept is no better than an invented price. What we intend to build is collected on the roadmap.
