Water Heater

Using cold water is perhaps not the best thing to do especially in cold weather. It can be aggravating as it can be harmful to your health. The solution for this is getting a water heater. Water heaters are equipped with mechanisms to allow water for use around the home to be heated prior to use. In many ways, it helps users of the water avoid using cold water and save them money that is used to boil water through other means. There are various types and kinds of water heaters each differing in terms of mechanisms and models. However, most have the same function and that is to heat water.

Most homes with water heaters operate on electricity that is used to drive the heating mechanism. The heater is supplied with electricity which then goes through some wiring and works to produce heat which is then used to heat up water that is supplied to the cylinder. Tank type water heaters are generally the standard found in most homes and it is uses fuel or electricity to heat the water. In terms of fuel, this type of water heating uses gas or natural propane. Electric models are simpler in mechanisms and rely on a power cable that connects the electric service panel directly to the heater. This type of hot water heater is able to heat water as well as storing the heated water and supply it readily when it is needed for use. The water heater is able to retain the heat of the water through the insulation installed within the tank. These types of heaters also have supply and delivery pipes installed in order to allow water to be distributed in the home on demand. Also there are pipes that lead water into the tank for the purpose of heating.

Alternatively, there are electric water heaters which work quite differently from tank type water heaters. Like tank type, it uses electricity to generate heat which is used to heat the water. It uses a 220 volt circuit to do this. The current of electricity passes through an electrical resistance unit or units (depending on the capacity of the system) and to the thermostat. The thermostat then senses water temperature and the switch adjusts accordingly to heat the water. The good thing about a thermostat control is that the user can control the temperature of water to keep it moderate and not too hot and not too cold. Additionally, the control of temperature allows the user to save energy and electricity costs. However, this type of water heating does not include a water storage mechanism. It only heats water on demand and only supply it after the individual has set the timer and the temperature.

In terms of effectiveness, both types of water heaters provide hot water as needed by the users. When choosing which one will work best for you depends on your needs. For instance, if you hot water use is on the higher side, you may need a water heater that is able to store the water that is heated. This will allow you to access water at anytime. On the other hand, if your use of hot water is not necessarily much, you can opt for other means which allow time for water to be heated before it is supplied to you. If you are considering getting a water heater, there is much to research about. Water heater installation is only the first step in the entire process. Installation of a water heater is the initial step in getting your home a water heating system.

Having one of the top water heaters installed in your home is good for the working of your home because it ensures the well working of a system. Like every other system, there comes a time when it will need repair. Water heater repair is another consideration to put into thought. In terms of water heater, getting a good servicing company to work with you from the beginning is one way you can have a reliable service of repairs when needed. The company you work with is likely to know the heaters well and hence, able to fix arising issues accordingly and efficiently.

    Great video. I just replaced both elements in my water heater, but I still
    don’t have hot water for very long. Sounds like I need to have the
    thermostats checked.

  2. William Boyer says:

    When I tap the side of the thermostat unit with a hammer, the hot water
    heater restarts. It eventually shuts off when the water reaches the
    designated heat setting. The next day I have to start it again the same
    way. What’s going on?

  3. barb r says:

    why would a hot water tanks water start getting scalding hot. We changed
    both thermostats so it wasn’t them. please help?

    great video, but I should already expect that from electronicsNmore, you
    are da Man
    thanks mike

    sir, thankyou very much for your time, dick bailey

  6. electronicsNmore says:

    +tonycstech If you raise the temperature setting of the thermostat and it
    does nothing, then either the water is already too hot, or the thermostat
    is faulty. Make sure you are testing from the correct screws. When the
    upper turns off, the lower turns on if the water is not hot enough. (.3
    ohms to show continuity is a little high). I would touch both probes of the
    meter together to see what you get. Should be close to zero ohms.

    Thanks, we used your video to help make repairs on our water heater. Got
    hot water again. I shared your video. Thanks. You speak clearly and show
    easily what you are doing. Great tutorial.

    Hi and thanks for the video. I’m having a problem with my water heater, the
    reset button keeps tripping. I changed both elements and thermostat, but it
    does the same thing. When I perform the thermostat test the thermostat does
    not click when the temp is changed to the highest or lowest setting. I’m
    using a digital meter, and I still get a reading when the thermostat is on
    the lowest setting. Not sure where to go from here and help would be
    greatly appreciated.

    I need to know what the hell do you do, if you fail the very first step?
    Getting 120 from black to ground, and 120 from red to ground, but cannot
    get 240 from black to red.
    EDIT… mother fucker… the house had a separate junction box JUST for the
    water heater… no wonder I couldn’t figure it out… so angry.

  10. Scott Thourot says:

    at 4:23 of your video, you test the thermostat for continuity at the lowest
    temperature, and if working properly, you say it should have no continuity.
    Well, I tested my thermostat (HWH had no power to it, as the breaker
    tripped) and it had continuity on both the high and low temperature. I
    removed it, thinking it was defective, and went to hardware store and
    tested 2 of their thermostats before buying them, and they tested the same
    as my faulty thermostat. I then realized this test for the thermostat did
    not seem to be a universal test. Please explain why my thermostat had
    continuity at the lowest temperature setting… I am guessing that since
    the water temp was less than 90 degrees, there was still continuity since
    the water needed to be heated. Is this correct? If so, how do you test the
    thermostat on a HWH that is not on or heating??

  11. Jim Hill says:

    Thanks for your clear, slow, guidance. I think my heater passed all these
    tests, BUT i think i pushed the reset button(why would the button fault?)
    …Also when removing the top cover and insulation behind, i noticed the
    insulation was very warm, is that an indicator of something?…I guess i
    have to wait for the heater(only 6 years old, its a 30 gallon for the
    in-law suite) to stop heating again and perform the test again without
    pushing the reset button.

  12. Jean-Denis Côté says:

    If I test the voltage on the two top screws on the upper thermostat, I get
    0. If I test either one of them + the ground, I get 120. Any idea why?
    Shouldn’t I get 240 by testing the two screws?

    hi,i installed a electric water heater in rental property and house was
    empty 2 months.after install gate valve for water supply to water heater
    started to leak,i repaired valve and now when I turn breakers on top
    element sparks at yellow wire.why would element spark,i dried water and
    insulation feels dry,what else could cause this to happen? thanks any input
    could be helpful,TIM

    I have checked everything while following the video and everything checked
    good. My multi-tester has one Ohm setting (no low). Two months and
    my problem still exists.
    Hot water tepid on occasion and super hot on others. Like a runaway
    thermostat. Reset button has popped. I did replace upper thermostat and now
    I feel that it was not the problem as I still have a wide range of
    temperatures….mostly good, but at times it is extreme. I love your video
    as it is easy to follow, I have hearing loss and found it difficult near
    the end. But still very much grateful! I hope you can help thank you…..

    my Rheem Pro 415 water heater is making a hissing/whistling sound. What is
    the problem

  18. Nic Reid says:

    Hey, if I go through that entire test that you described and everything
    looks good, where do I go from there? The water heater is a 2004 model.
    Its got an expansion tank on it. Could it be that? There appeared to be a
    bit of soot (yeah, weird as its electric) above the top access panel on the
    outside of the tank.

    Awesome tutorial, by the way.

    Going to buy a volt meter tomorrow. What options/features should I make
    sure it has? 250 volt range is one of them :-)

    We ran out of hot water last night -uncommon did not seem to recover as it
    did.. My feed water is just above freezing I have well water/ 5′ perm
    frost(still)
    I Ran thru everything step by step. as you did. I get 240v in.- min
    resistance no short elements. All appears Ok.
    Turned everything up to 130 [email protected] feed screws to top element- both T
    stat and element screws read 0 voltage(110 @ element screws if if meter
    grounded to tank.) @ bottom element 240v at screws is warm. You said
    something about working alternately? Is too hot for top element to come on
    ? Thanks for help in advance.

    Is the reset button faulty if the meter does not react when you touch the
    screws and if so what do I do in that situation

    I have a stupid question .. what will happen if you test the water heater
    elements with the power on ?
