【High compatibility and easy installation】Most tank water heaters have exhaust vent, water and gas pipe that can be universally used in tankless, requiring only a simple re-layout. If installing a tankless water heater in a new house, its compact size makes it easy to install. Of course, we recommend that all installations are carried out in accordance with local building and plumbing codes by licensed professionals.
【Smaller size and better performance】It is only 1/4 the size of a 50 gallon tank water heater, yet it produces approximately 4.0 GPM of hot water through 90,000 BTU for both bathroom and kitchen hot water demand. The highly integrated components also provide greater safety from water pressure surges without the need to install an expansion tank.more
