The State ProLine® XE GTS-340X3-PIH Indoor Tankless Condensing water heater uses up to 180,000 BTU/hr of propane to deliver an endless supply of hot water for a 2.5-bath home in northern climates and a 3.5-bath home in southern climates (one shower head per bath).
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.
This ENERGY STAR® certified Ultra-Low NOx model with condensing technology has a Uniform Energy Factor of 0.95 and meets the ASHRAE 90.1b-1992 energy efficiency requirements, making it environmentally friendly and reducing operating costs.
The GTS-340X3-PIH uses commercial-grade copper alloy for the heat exchanger tubing and is approved to work with an external recirculation pump and cross-over valve. Indoor models are certified up to a 10,100 ft. altitude.
The GTS-340X3-PIH tankless condensing water heater provides years of hot water through innovation and quality and is backed by an industry-leading 15-year limited warranty.
