Performed preventive maintenance on Rinnai tankless water heater. Descaling of a tankless water heater is recommended by most manufacturers to ensure proper function of the unit. It is recommended to be done once a year or as needed depending on the quality of the water. This is performed by recirculating a descaling solution in the tankless water in order to remove scale build up inside the heat exchanger. Its the equivalent of an oil change in your car. Some warranties on the unit may be voided if no such maintenance is performed on the unit.
