Expert Review
The Navien NPE-240A2 is the tankless water heater we recommend most for Nassau County homes upgrading from tank systems. Its built-in ComfortFlow recirculation pump eliminates the cold-water sandwich effect that plagues many tankless units. With dual stainless steel heat exchangers and 0.97 UEF, it extracts maximum energy from natural gas. The NaviLink WiFi module lets homeowners monitor performance and schedule recirculation times. At up to 11.2 GPM, it can handle simultaneous showers and appliance use in most Long Island homes.
