Norris Mechanical is proud to offer our customers Navien tankless water heaters. With 98% efficiency and offering an unlimited supply of hot water, these tankless heaters take up only a fraction of the space used by a traditional water heater. The Navien tankless system doesn’t keep a tank full water hot and waiting for your use like traditional water heaters, it heats the water only when you’re ready for it–saving you in energy costs! And for 2013, your purchase of a Navien equates to a tax rebate of up to $300!
