Maintain and extend the lifespan of your tankless water heater with the Chromex Tankless Water Heater Cleaning Kit. This kit includes everything you need to fully maintain your tankless water-heating system. It comes with step-by-step instructions that are easy to follow, and it connects easily to the tankless isolation valves using the supplied 6-ft. hoses. To ensure a water heater continues to work at an optimum level, it is necessary to descale the appliance. This will mean removing the deposits that can build up from the use of hard water. The kit comes with a 3.5-gallon bucket with lid, 1/6-HP pump, 2 steel hoses, an elevated pump grate, and a maintenance scheduling tag. The hoses easily connect to tankless heater valves and the kit will clean most heaters in 30 minutes or less. Just add 2-3 gallons of vinegar, or your own descaling solution.
