What it is
Underfloor Planner is a design aid for wet underfloor heating. It lays out pipe loops, measures them, and estimates heat output with the EN 1264 method. It does not replace a room-by-room heat-loss calculation, the pipe and manifold makers’ installation data, or a competent installer. Check the design against them before you build; you remain responsible for the installation.
Pro
Pro costs €39, paid once through Stripe; there is no subscription. It unlocks the Pro features that exist on the day you buy (unlimited rooms per project, the installer PDF and the schedule export) for the email you pay with, in any browser where you restore it with that email.
14-day money-back guarantee
If Pro isn’t right for you, email us within 14 days of buying and we refund the full amount, no questions asked. Pro stops working for that email once the refund goes through. EU and EEA consumers also keep their statutory right of withdrawal.
Liability
We work hard to keep the calculations right and fix errors quickly when they are reported. To the extent the law allows, our liability for any claim about the service is limited to what you paid us. Nothing here limits rights you have as a consumer under EU law.
