Colin from Wilmec Systems installed our heated driveway (hydronic snow melting system) It was an involved process including installing two boilers & manifolds to circulate the heated glycol to lengths of tubing that he laid up and down the driveway. After the concrete was poured, he balanced the system and integrated the sensor with the controller. He was extremely diligent in ensuring that we understood how to operate the system on-site and remotely. I highly recommend his work
