Tankless Non-Condensing Concentric Vent water heaters deliver hot water efficiently to domestic systems, storage tanks, recirculation systems, and combined heating applications. These fully modulating, gas-fired units feature sealed combustion and a power-vented flue, ensuring optimal performance. With a concentric vent design, they support both vertical and horizontal vent termination installations, accommodating up to 43 feet of vent length with four elbows. The copper heat exchanger offers 25X better heat transfer than stainless steel, stabilizes outgoing water temperature quickly, and minimizes pressure drop. Designed for indoor use, these models comply with air quality standards, including SCAQMD Rule 1146.2, and meet low NOx emission requirements of 14 ng/J or 20 ppm.
These water heaters prioritize safety and convenience with built-in freeze protection, overheat cutoff fuses, and constant temperature monitoring via inlet and outlet thermistors. They operate using electronic ignition, eliminating the need for a pilot light, and include features like flame sensors and air-fuel ratio rods for efficient combustion. The GT-510C model supports Easy-Link for up to four units and Multi-Link for up to 20 units, enabling scalable solutions for residential and commercial applications.
