How To Maintain Tankless Water Heater ?

Tankless units are great, but to keep their high efficiency rating they must be maintained.  Almost all water sources have minerals like calcium that can scale up inside our water heating systems.  After isolating the power and water sources, be sure to drain any residual hot water from the tank. Now remove the caps from off the cold and hot water purging valves.  You can use these valves to fill the heat exchanger with vinegar.  The vinegar will break up any scale within the unit. Leave for approximately 10 minutes.  Now flush the system with water.  Last be sure to clean the filter and strainer screens as they will be clogged with the loosened scale.

How To Replace Water Heater Element ?

Electrical hot water tanks work off of immersion heating elements.  Generally a hot water tank will have two of these elements working in tandem.  After taking the necessary safety precautions andisolating the power and water sources, be sure to drain the tank.  Now locate the junction box that houses your two elements.  This is typically located on the front of the unit.  Remove the units and replace in kind.  Some are screwed into the side of the tank, other designs utilize a flanged system.  The sealant you use to ensure that the elements don’t leakneeds to be rated to handle high temperatures.

How To Repair Tankless Water Heater ?

At times all things need maintenance.  In the case of electrical tankless water heating units, repairs are not too hard. You just need some basic hand tools and a bucket.  The primary repairs generally center around the heating element.  First ensure that the power is turned off at the breaker and supply water valves are all closed off as well.  Drain the hot water from the holding tank.  After removing the cover, locate the electrical heating element. Disconnect the wiring and remove the element. After cleaning the rubber seal ring, install the new heating element. Reverse the process and your done.

How To Maintain Water Heater ?

General maintenance on water heaters is not rocket science. There are a few things that need to be done each year. First wipe the tank down inspecting it for leaks.  Every hot water tank will have a pressure relief valve that should be released once a year.  This is a safety device that will pop off if the pressure in your water heater gets too high due to a malfunction. Relieving this valve tests to ensure that it is in proper working order. Please exercise caution as the hot water in the tank can burn you. Check the thermostat to ensure that it is in proper working condition.  Last, there is a zinc rod installed in hot water tanks called an Anode Rod that protects your tank from erosion. When six inches or more of the internal wire starts to show, the Anode rod needs to be replaced.

How To Replace Dip Tube ?

The dip tube is a plastic tide that runs the center of your hot water tank.  Its purpose is to bring the cold water into the tank so that is can be brought up to the proper temperature.  The tube moves water from the top of the tank down to an opening in the bottom.  This ensures that the hot water stays at the top and the cold water starts its heating process from the bottom.  Replacement is simple.  After shutting off the power and closing the water supply valve, remove the free standing nipple located at the top of your tank.  Then pry out the old tube replacing in kind. Last put everything back together and you’re good to go.

How To Replace Thermostat?

There are generally two heating elements, the upper and the lower. The thermostat will cycle these on and off to bring the water tank up to the desired temperature. Replacing the thermostat is a relatively easy and straightforward procedure.  First ensure that the supply power is off by flipping the breaker. Then remove the cover and ensure that there is no electricity at the unit by using an electrical meter. Next disconnect the wires and remove the thermostat from its mounting bracket.  Clean the surface of the tank where the unit inserts it’s sensing bulb.  Now install the new thermostat.
