BEFORE: This picture shows a Poly-B piping radiant heating system in Surrey, B.C.
The picture speaks for itself! This system has multiple radiant, in-floor zones, a system plagued with continuous breakdowns and costly repairs. The cast-iron boiler was not salvageable. The only appliance which remained is the indirect-fired hot water tank.
AFTER: Heat Tech redesigned the boiler room with Tekmar Controls. The Hydrotherm boiler was replaced with a cast-iron Viessmann ECD Vitogas 050 boiler
A fully-automated 4-way mixing valve with actuator, a Tekmar 363 Boiler/Reset control with outdoor and pipe temperature sensors ensure even and reduced water temperature to the floor heating. A cartridge type by-pass filter helped to clean up this system over time. This system was repaired in the year 2000; no further repairs or failures have been reported*. Repair & operating costs were dramatically reduced.
