Condensing Tankless Gas Water Heater

Navien America Inc. has released its Condensing Tankless Gas Water Heater, which boasts 98 percent efficiency. Its dual stainless-steel heat exchangers are resistant to erosion and operate with relatively low water temperatures, minimizing damage from hard water conditions. The water heater’s efficiency results in lower exhaust temperatures, allowing for the use of 3-inch Sch 40 PVC venting, which provides cost savings and reduces installation time.
