Due to this, producers of tankless water heaters typically require these techniques to be flushed yearly to keep up their warranties. Some producers permit for longer intervals, like flushing as soon as each 3 years, if a complete residence water filtration system is put in. That is one other instance of how the standard of the water inside a water heater can have an effect on its lifespan.
