Heated floors and radon the water pipes are in the slab
Hydronic heat runs through the same slab the radon moves under. The warmth does not suction the gas and it is not a measurement. Test the way you would in any other house: occupied room, 91 days, heat on, including that floor if you normally use it.
If a system is required, the installer avoids the loops. Hand over the tube plan before anyone drills. Slab on grade. The system.
The 4-day test is a first reading. The 91-day test covers the three-month minimum Health Canada asks for. Both are $59 before tax. Shipping, the return and the lab are included. Tax is extra. The PDF report goes out within 2 business days after the lab receives the detector.
Above 200 Bq/m³, mitigation starts with a quote. Gaz Radon is C-NRPP certified and ships kits across Canada. See the Canada test page.
