Clean the Filters
Water that enters your tankless water heater may have impurities and dirt. To ensure that clean water enters your water heater, an in-line screen filter is fitted just below the cold water inlet, at a right angle. You must clean this filter from time to time, say every 2-3 months to make sure that your system works efficiently and you get clean hot water from your heater. If you receive dirty or hard water from the backend, you should clean your filter every month.
Start by turning off the cold water supply to the heater. Unscrew the filter with a black cap and slide it out. Clean the wire mesh cylinder filter under running water. You can also soak it in vinegar for half an hour and scrub to clean tough debris. Reinstall the filter in the heater once you have cleaned it and turn on the cold water supply.
De-scale the Heating Elements
If you have the hard water supply to your house, your tankless water heater may fail faster. The scale and minerals dissolved in hard water get deposited on the upper, lower, or both heating elements and even on the inner surfaces of the water heater. To extend the efficiency and lifespan of your heater and to reduce the chances of scalding and tank failures, you must de-scale the heater every year. De-scaling can be done using white vinegar.
Turn off all the valves and supplies to and from your tankless water heater, especially the cold water supply and the hot water outlet. Turn off the main power supply to the tank. Remove the purge port valve caps from the purge valves. Connect a 6-feet hose to cold and hot water valves each. Dip the hose connected to the cold water supply side into a bucket with 5 gallons of white vinegar. Plug a pump to this hose. Place the other end of the hose connected to the hot water side in an empty bucket. Start the pump and allow the vinegar to circulate in the tank for 20 to 25 minutes. After 20-25 minutes, replace vinegar with cold water. Turn off the pump, allow the cold water to drain out from the hot water outlet completely, and disconnect the hoses. Put the valve caps back in place, attach cold water and hot water hoses, and turn on the water and power supply.
Along with these maintenance steps, you must also check the valves on a regular basis. The cold Edmonton winter can freeze your water heater valves and make them inefficient.
