Reliance non-condensing gas tankless water heaters offer versatile solutions for both indoor and outdoor installations, meeting a wide range of residential needs. These units deliver reliable, on-demand hot water with impressive performance—maximum flow rates up to 10.5 gallons per minute and ultra-low NOx emissions for environmentally conscious operation. With models available for indoor and outdoor use, homeowners can select the ideal configuration for their space, whether it's a compact indoor utility room or an exterior wall. All models feature robust copper heat exchangers, electronic ignition, and freeze protection, ensuring dependable operation in various climates.
For enhanced durability and reduced maintenance, Reliance tankless water heaters are available with patented X3® Scale Prevention Technology. X3® models require no annual descaling and maintain like-new performance up to three times longer than unprotected units, making them ideal for areas with hard water. Customers can also choose base models without X3® protection, which offer the same high efficiency and performance but require standard flushing maintenance. Each model is backed by industry-leading warranties—15 years for X3® models and 10 years for base models on the heat exchanger—providing peace of mind and long-term value.
