For commercial applications, the Therm C 1210 ESC tankless water heater provides up to 98 percent thermal efficiency. The gas-fired unit features a space-saving design, affording easy servicing access, and can be cascaded using up to 24 units to satisfy requirements up to 240 gpm for applications such as tank loading, solar thermal recirculation, radiant floor, and space heating. Its condensing heat exchanger captures heat from exhaust flue gases and uses the latent heat to preheat incoming cold water. Venting options include direct, vertical, or horizontal, and PP common venting of up to four units. The units are available in both NG and LP models. Energy Star-rated, two new models of condensing gas-fired tankless water heaters are available for domestic hot-water-on-demand applications. The Greentherm C 1050 ES and C 950 ES models feature condensing technology with an energy factor up to 0.94. They are now equipped with an automated and fully modulating bypass for unsurpassed temperature stability. The wall-mounted units offer multiple venting options including fast and simple concentric PP up and out, and up to four unit cascades vented together through a sidewall or roof with the company’s new polypropylene common venting system.
