This radiant in-floor heating system in Vancouver, B.C. with Poly-B (grey) tubing was upgraded to a computerized system with Tekmar controls and a heat exchanger package, which separates the radiant Poly-B water from the boiler water. This setup prevents corrosion of the boiler, pumps and all surfaces prone to rusting.
Additionally a by-pass filter was installed, assisting with the cleanup of the soiled floor piping. Further, this reduces the necessity for flushing the system.
