Details: The best of both a tank and tankless water heater combined into one superior unit. The crossover wall allows you to enjoy the benefits of a high efficiency unit without surrendering your need for endless hot water and abundant water pressure. The crossover design prevents spontaneous bursts of cold water, which are typical for most tankless water heaters. As user demand increases, the crossover can provide hot water at higher pressures for multiple fixtures and has built-in recirculation capabilities.
