The State ProLine® XE GTS-510CX3 Indoor Non-Condensing X3 Tankless water heater uses up to 199,000 BTU/h of natural gas or propane to deliver a continuous flow rate of 10.0 GPM. Featuring sealed combustion and a power-vented flue, it supplies hot water directly or indirectly to domestic hot water systems and can also supply water storage tanks and recirculation systems.
This model has a small footprint and is wall-mountable, providing a variety of installation options. The GTS-510CX3 complies with Ultra-Low NOx regulations, meets the energy efficiency requirements of ASHRAE 90.1-b 1992, and has a Uniform Energy Factor of 0.81.
Built-in X3® Scale Prevention Technology helps maintain like-new performance by protecting the heat exchanger from build-up. Scale-prevention protection can prolong the life of the heat exchanger by up to 300% compared to an unprotected unit.
The GTS-510CX3 tankless water heater provides years of hot water through innovation and quality and is backed by an industry-leading 15-year limited warranty.
