Why Choose Sterling Hydronics Quality:  Sterling finned-tube radiation is built to last. Internal welded gussets integrate with and support the enclosure. Ball bearing element supports are nylon isolated to eliminate the transition of noise due to expansion and contraction. Aluminum or steel fins are mechanically bonded through expansion to copper or steel tubing, ensuring quiet operation, long life, and maximum heat transfer. All paint finishes are oven baked. Comfortable:  Hydronic perimeter heat gently blankets the exterior walls and glass, eliminating the drafts and local cold spots which often occur with forced air heating systems. Through the combined effects of radiant and convection heating, people are more comfortable at temperatures 2-4 degrees lower, offering significant energy savings. Humidity levels are also easier to maintain as heat provided by hydronic finned-tube radiation does not produce the lower humidity levels often associated with forced air and electric heat systems. Rooms can be easily zoned with individual temperature controls to provide that extra comfort. Flexible:  The piping used to distribute the hydronic heat is much smaller than the ductwork used in forced air systems. This not only provides more usable space for the occupants, but offers much more flexibility when designing buildings or major renovations. Future layout changes, such as enlarging the rooms and moving partitions can be much more easily accomplished. Quiet:  Hydronic finned-tube radiation systems have no large fans, but deliver hot water to the individual zones by quiet, remote pumps. Without ductwork, there is no conduit to carry the system's fan noise and other sounds throughout the building. Clean:  Hydronic perimeter heating systems are cleaner and healthier. There is no ductwork and fans to redistribute dirt, odors, and germs through a building's forced air system. Economical:  The pump energy required in hydronic perimeter systems is much less than that required for fans in forced air systems. The amount of energy to distribute the same amount of heat in forced air systems is typically 10 times greater than that needed for the pumps in hydronic perimeter systems. Forced air systems also have significant heat loss and leakage in the duct system, while there is no leakage and much less heat loss through hydronic piping. Additional savings can be realized with the use of outdoor air reset controls which are easily applied on hydronic perimeter systems. Fuel Options:  Because hydronics perimeter systems employ boilers as their source of heat, the system can usually use any energy source including gas, oil, electric, solid fuel, or solar. The boiler used to provide the hot water heating can also be used for other duties in the building including domestic hot water heating, snow melting, swimming pool heating, etc. Dedicated Heating:  A single system that both heats and cools must have compromises designed in. Delivering heat from below and allowing the heat to rise is much more comfortable and preferable to overhead heating, which is more appropriate for cooling systems. Any additional expenses required to install dedicated separate systems for heating and cooling is paid with greater comfort and operating efficiency. For dedicated heating, hydronic perimeter heat is the best choice. IBR Ratings:  As a member of the Hydronic Institute of Boiler and Radiator Manufactures (IBR), Sterling meets strict industry performance requirements. All Sterling performance ratings are based on IBR testing or are IBR approved, where applicable. Sterling offers the industry's most complete line of finned-tube hydronic heating elements and enclosures. We engineer and manufacture products that deliver reliability, long life, and value.
