Tankless Water Heater and turning off main water supply

  • Tankless/combi will simply not start if there is insufficient flow (this is clearly stated on the tech label), and the minimum flow required to allow fire to light is often about 2L/min, which is inherent in their mode of working. The majority of them employ a microswitch to sense the flow and a temperature sensor to alter the flame, while some just monitor the flow and modify the flame in response. It is not necessary on DHW since some have a minimum pressure sensor and others do not. DDSDDS2,0597 silver badges14 bronze badges2,0597 silver badges14 bronze badges2,0597 silver badges Tankless systems are equipped with flow sensors, so if you are merely closing down the water supply valve and then reopening it, you shouldn’t be too concerned about causing a leak. Having said that, shutting down the water supply might cause changes in the pressure in the system as the temperature of the water changes over time. I don’t believe it would be a source of concern. However, every time the valve is closed, the water is no longer in the system. Installing a potable water expansion tank is a wise decision. This is an expansion tank for potable water. www.amazon.ca NPT is almost primarily used for 3/4″ NPT. You would need to use a gauge to measure your static pressure (the pressure that exists while the taps are closed and the main is open). Then, using a bicycle pump or, preferable, an air compressor, pump air into the air nipple (located at the bottom of the tank as shown above) to bring it up to the same static pressure as the tank before mounting it. Additionally, it is recommended that a service valve be installed. Posted on March 6, 2019 at 3:31 p.m. Joe Fala is an American football player who plays for the Los Angeles Lakers.

  • On the waterside, I’ve never been across one before. They must be able to deliver on their promises. Navien is the only software I use. They make use of a flow transducer/hall effect sensor to do this. I’ve made a few modifications. But I’ve put in hundreds of units throughout the years. In the garage, I’m still dealing with a defective sensor. I attach it to a 5vdc power source and an LED while blowing into it, and it knocks my kids’ socks off as they watch the light flicker in delight. Is it a variable pressure transducer, or something else? Or is it simply a switch with the gas being throttled by another sensor? On March 6, 2019, at 5:47 p.m.
  • It can be used as a variable transducer on some systems and as an on/off switch on others
  • in most cases, the second is used and the flame is adjusted by a temperature sensor
  • if the flow rate is used to determine the amount of heat required, boilers will not be able to guarantee the temperature at the output of the boiler. As an example, if the acquaduct is 5° and the boiler is set to 60°, the DHW may be 55°, but on a 20° acquaduct, the DHW may be 75° since the temperatures are calibrated with a 10°C intake. This type of control is often found on older, mechanical-only instant-boilers, whereas modern instant-boilers with ‘electronic control’ employ a temperature sensor and an on/off flow switch. at 8:44 a.m. on March 6, 2019
  • A tankless system also eliminates the requirement for an expansion tank because water is cold and heated only while the system is operating, resulting in no thermal expansion in a ″no-flow″ condition. at 8:47 a.m. on March 6, 2019

Changing the temperature of the water can be done from the face of the unit on both whole-house and point-of-use models, and some units even include extra capabilities that enable you to temporarily override the water temperature.

Electric Tankless Water Heater

  1. Identify and shut down the circuit breaker that supplies electricity to a small electric tankless water heater. Start by turning on all of the hot water taps that are served by the unit. Opening hot water faucets that are not linked to the water heater is not recommended.
  2. Allow the faucets to run for about 1 or 2 minutes to clear any air that may have accumulated in the lines. Activate the circuit breaker for the tankless water heater and close all of the faucets.
  3. The temperature of the water may be adjusted by turning the temperature dial. Despite the fact that you may have various temperature options to pick from on the dial, the United States Department of Energy recommends adjusting the temperature to 120 degrees Fahrenheit to avoid scorching and to lower your energy bills.
  4. Check that the water shut-off valves attached to the tankless water heater are fully open on both the intake and output water lines. Determination of the hot-water outlet that provides the greatest quantity of hot water Example: If the water heater serves both a washing machine and an entire bathroom, the bathtub faucet should be used because it provides more hot water per minute than a vanity sink or the washing machine does.
  5. Substitute a 5-gallon bucket beneath the bathtub faucet to collect water. Turn on the hot-water faucet completely and hold it there for exactly one minute. The amount of hot water in the bucket should be measured. Slowly close the hot-water outlet shut-off valve and fill the bucket for one minute at a time until the output of water is between 2 and 3 gallons per minute to guarantee that your water is constantly at the right temperature
  6. if necessary, repeat the process.

Gas Tankless Water Heater

  1. To turn off the power to your gas tankless water heater, turn off the circuit breaker that supplies it with electricity. Some versions feature power buttons that allow you to do this function right on the unit itself. Despite the fact that gas warms the water, electricity is required to run the control panel and the ignition system.
  2. Locate the gas shut-off valve that supplies gas to the device and close it. Turn the valve counterclockwise until it is in the ″Off″ position.
  3. Wait 5 minutes to ensure that any gas has been removed from the device. Immediately evacuate the premises and contact your gas provider from a neighbor’s residence if you detect gas after 5 minutes. Please do not make calls from your house. If you do not detect any gas, you should proceed with starting the unit.
  4. Turn the gas shut-off valve counterclockwise to the ″On″ position until the gas is turned back on. To restart the equipment, re-energize the circuit breaker or turn on the power switch.
  5. Temperature control arrows on the tankless water heater control panel may be used to set the temperature to 120 degrees Fahrenheit by pressing on the up or down arrows. To operate your unit from within your house, if your unit includes a wired remote that allows you to control the unit from anywhere in your home, make sure that the remote is turned on before you begin setting the water temperature using the up and down temperature arrows.

Can An Electric Water Heater Explode?

  • Skip to the main content Is It Possible For An Electric Water Heater To Explode?
  • The response is an emphatic YES, without hesitation.
  • Electric water heaters have the potential to explode.
  • That is not to mean that you should be overly concerned.

Installing and maintaining your water heater by a genuine specialist is always the best alternative, as water heaters that are not properly installed and maintained nearly never fail.They are educated on what may and does go wrong with them, as well as how to avoid it in the first place.When water heaters are not properly maintained or installed, they can pose a serious threat.

  1. Observe the following indicators that your water heater may be about to blow up:

Signs That Your Electric Water Heater May Explode

  • Popping, pounding, or banging noises – Does it sound like popcorn is coming out of the heater’s combustion chamber? Over time, particles can accumulate in your water heater, causing obstructions that prevent warm water from rising to the top. It is the water bubbling beneath the accumulation that is making the popping sounds when it exits.
  • Gas leaks are frequently indicated by a sulfurous or rotten egg smell, which should be treated as a life-threatening emergency. If you are able to, switch off the gas and contact a professional as soon as possible. However, if you moved from gas to electricity and discovered that the original gas line had not been properly sealed, it is possible that the problem was caused by the original gas line being improperly capped.
  • It is usually found at the top of the heater and is responsible for releasing pressure as well as water from the tank when the heater leaks. If this valve is leaking, it signals that the pressure within the water tank has risen to an unsafe level, and it may even explode if the pressure continues to rise. If you observe this, you should immediately switch off your water heater.
  • Thermostat connections that are incorrectly connected — An improperly installed water heater is subject to a variety of concerns, including the possibility of an explosion, therefore it’s always best to have a competent specialist install and maintain your water heater.
  • Brown sediment in your water – When sediments build up inside your water tank, they ultimately loosen and flow with the water, creating a brown sediment in your water. This signifies that a sufficient amount of silt has accumulated within to form a blockage, which may result in an explosion.

How to Prevent your Electric Water Heater from Exploding

  • It is possible to take steps to guarantee the proper maintenance of your water heater, which will ultimately improve the overall safety of your property. If you are familiar with the normal functioning parameters of your water heater, you can check on the temperature and pressure valve to see if anything is wrong with it at any time.
  • Reduce the water temperature – It should be set between 120 and 130 degrees Fahrenheit, with typical recommendations of 125 degrees Fahrenheit. Scalding, scorching, or wounded skin, as well as catastrophic damage to your water heater and sewage system, are all possible consequences of exceeding this limit.
  • Make an appointment for a yearly tune-up – Keeping on top of your water heater’s maintenance should always entail having a licensed and dependable professional take care of the job for you. Your expert will be able to cleanse your water heater at the same time that they are checking for problems, which will improve the taste of your water as well as the efficiency of your unit.
  • Allow experts to do the task – As tempting as it may be to complete the work ourselves in order to save money, doing so may result in sloppy or unskilled work. A water heater that has not been properly installed or serviced is more likely to explode. When it comes to repairs, it is usually better to leave them to the pros.

We’ve also included an instructional video to lead you through the process for your convenience.

How To Turn The Water Off At The Leaking Water Heater

  1. Shut off the water heater by turning off the gas or electricity supply. The off setting is reached via clockwise rotation of a knob on the top of a gas water heater’s thermostat. The water heater’s thermostat is positioned near the bottom of the appliance.
  2. For electric water heaters, go to your circuit breaker panel and locate the breaker for your water heater
  3. turn it to the off position. For gas water heaters, use the same procedure as above.

Turn off the water supply valve. Turn the lever on the water shutoff valve counterclockwise until the water stops flowing. This valve is normally found on the right side of the cold line, on the top of the water heater, on the hot line.

  1. Drain The Water Heater If Necessary To Avoid Water Damage
  1. Connect a garden hose to the drain faucet, which is situated at the bottom of the water heater, and let it drain.
  2. Extend the hose to a lower area where hot or corrosive water will not cause harm.
  3. Drain the water heater by turning on the drain faucet. As water drains from the home, open a hot water faucet in the house to allow air to circulate into the water heater.

How To Turn The Water Off At The Leaking Plumbing Fixtures

  1. Then, at the leaky plumbing fixture, turn off the water supply by turning the lever on the water supply shut off valve clockwise until it comes to a complete stop. This valve is often found on the flex line or feed pipe that connects to the plumbing fixture in which it is installed. It might be directly behind or directly below the fixture (i.e. toilets, sinks, washing machine). In the case of leaking sinks, turn off the hot and/or cold water pipes as necessary.
  2. Turn off the water supply line if your toilet is leaking or overflowing.
  3. If your washing machine, dishwasher, or refrigerator is leaking, switch off the feed lines first.

Some situations, such as when the supply valve is not easily accessible or when the leak occurs before the shut off valve, will necessitate the shutting off of the main water supply.

How To Turn The Water Off At The Main Water Supply Shut-Off

Several choices are available to you when it comes to cutting off the main water supply. Decide on the choice that best fits your needs and circumstances.

  1. Turn off the main water valve to the home if it is still running. Then, turning the main water valve in a clockwise manner until the water stops flowing, turn it off again. If the main water supply has been turned off, open an outside faucet to allow pressure to be released and excess water to flow out of the system. If the main water supply has been shut off, open an outside faucet to allow pressure to be alleviated and excess water to drain out of the system.
  1. Remove your home’s main water supply from the city, which is normally located underground near the street and may be reached by turning off the water meter box. Access is granted with the use of a street key
  2. alternatively, you may contact your local water department or our helpful staff for assistance.

How To Turn Off The Gas Supply

Electric Hot Water Heater Not Working After Power Outage – Aztilac

  • Power outages are a common occurrence in the United States.
  • Usually, they are not a problem in and of themselves, but they can occasionally carry with them modest to serious issues.
  • One such troublesome circumstance is when an electric hot water heater fails to operate during a power loss.
  • Depending on what has gone wrong with the water heater, it might be anything as little as a faulty thermostat or something as serious as a malfunctioning water heater.

Water Heater Takes Time To Heat Water

  • If you have used up all of your hot water while the power was off, you will need to allow your water heater some time to heat up some more water before continuing.
  • It is not intended to be used as a quick heating device.
  • It takes around half an hour to forty minutes for a gas-powered water heater to heat a tank full of water.
  • A conventional electric heater takes almost twice as long.

Even after this period of time has passed, if there is still no hot water, you should be concerned.

Check The Power Supply

  • Although the electricity has been restored to the interior of the house, it is conceivable that the power supply to the water heater has not been restored yet.
  • There is a possibility that, as a result of the outage, just a portion of the power was restored and not the entire system as a whole.
  • Perhaps your water heater is one of the items that has been impacted.
  • With the use of a ″circuit tester,″ you can determine whether or not your water heater is receiving electricity.

If this is not the case, you must determine why.There are a few of possibilities as to why this is happening.These are the ones: 1.

  1. Tripped Circuit Breaker — When the power was restored, it is possible that the circuit breaker was tripped as a result of a spike in electricity.
  2. In order to correct the situation, you will need to reset the tripped circuit breaker to the ″On″ position.
  3. After that, your water heater should be able to resume regular operation without any more intervention.
  4. However, if the circuit continues to trip, it is preferable to call your local HVAC specialist to come and inspect the situation.

Keep in mind that the circuit only trips when there is an overload.So it’s possible that you’ll need to re-access your electrical and wiring systems.Wires that have been cut or burned — A tiny animal or mouse might have chewed through the wire that connects to the water heater while the power was off.Similarly, the cable might have been accidentally severed or burned as a result of overheating.Whatever the case, the electricity was restored, but the water heater was unable to operate due to the damage to the cables that had been exposed.

In order to repair the wires, you will need to determine where they were eaten or burned and where they were severed.Because of the potentially hazardous nature of this operation, it should be left to your plumber or electrician to complete properly and efficiently.3.Faulty Switchboard — Another possibility is that the problem is with the switchboard, which is where the water heater is powered.

It’s possible that the earthing isn’t done properly, or that the connection is loose.This is something you can verify on your own if you have a basic understanding of electrical principles.In the event that you have any reservations, it is preferable to contact your electrician.Fourth, weak connections in the connector that links the water heater to the power supply source can be caused by a malfunctioning switchboard, just as they can be caused by a bad fuse.

Open the plug and make sure all of the wires are snug.If any wires are hanging loose, reposition them in their proper positions and tighten the screws.Your water heater should be fully operational and ready to meet the hot water demands of your home.When the water heater does not get electricity, it is possible to experience any of the scenarios listed above.

If, on the other hand, the power supply is operational, you must consider a few more factors, including – 1.Thermostat malfunction — It is possible that the water heater’s thermostat failed, and that the power outage was only a convenient cover-up.Attempt to reset the thermostat by first lowering it to zero degrees Fahrenheit.Remove it from the heat for a couple of minutes and get it up to the temperature you like.Hopefully, the problem with your water heater not working after a power loss has been fixed.The odds are that you will have to replace the thermostat itself if this does not solve your problem.

Consult with your local plumber to get it checked out and replaced, if necessary.2.Low/High Voltage — In order for your water heater to work, it requires a specific minimum voltage.The majority of household water heaters work on 220/240 volts, with a few operating on 110/120 volts.As a safety measure, if the voltage is less than the minimum or greater than the maximum, the device will shut down or cease to work as intended.There is a good chance that your water heater is not receiving enough power because there is an issue with your home’s electrical system.

Immediately consult with a reputable and skilled electrician to determine the cause of the problem.When the voltage is restored to normal, your water heater will automatically restart and begin working again.3.Exhausted Heating Components – It is possible that all of the heating elements in your water heater have been extinguished.

Typically, this is a slow and steady process that occurs as your water heater becomes older.You might try replacing the burned components in your water heater to see if it helps to extend its life.To be quite honest, if your water heater is more than a decade old, it is strongly advised that you replace it.4.Tripped Reset Button – Another possibility is that the reset button on your water heater has been tripped accidentally.

This trip might be caused by a defective thermostat, a shorted heating element, or a faulty electrical connection.Until you solve this error, your water heater will not function properly.This reset button is often red in color, and when it trips, it bursts out of the case.

It has to be pushed back into place.

Closing Thoughts

  • A water heater will never be harmed by a power loss on it’s own.
  • When the electricity is restored, a rapid voltage spike, on the other hand, might cause the water heater to fail.
  • However, this will only happen if the circuit breaker does not function properly.
  • As a result, it is critical to ensure that the electrical system in your home is dependable as dependable as possible.

Aside from that, your local plumber or plumbing firm should be able to take care of any water heater difficulties you are experiencing.Never attempt to repair or replace your water heater on your own.It is not a toy that may be used for recreational purposes.

Reasons Why Tankless Water Heater Running Hot and Cold

  • If you have a tankless water heater, you are probably aware that it will occasionally alternate between hot and cold water.
  • This is due to the fact that tankless heaters are intended to operate without any interruptions when heating water.
  • It is not unusual for tankless heaters to be operating at full capacity one second and at half capacity the next.
  • The concern is that this might potentially reduce the efficiency of your tankless water heater, which could result in an increase in your energy bills!

Let’s talk about why your tankless water heater fluctuates in temperature, what causes these variations, and what you can do to avoid them in the future.

Cold Water Sandwich

  • Despite the fact that it is quite unusual, you may encounter a tankless water heater problem known as a cold water sandwich.
  • Your water heater will produce hot water for a few seconds, followed by a blast of cold water (cooler), followed by an abundance of warm water, all at the same time.
  • It almost feels like your tankless water heater shuts off for a split second before starting to heat the water, but this is not the case.
  • This can occur when a fixture is utilized shortly after another fixture has been turned off, as is the case in this example.

Prior to the gas burner being able to fully heat the heat exchanger, you’ll receive some hot water held by the faucet, followed by cold water from the tankless water heater.If you’re washing your hands, a cold water sandwich isn’t likely to be a major inconvenience.However, it might be inconvenient if you’re taking a chilly shower when you’d prefer hot water.

  1. Here’s how to get rid of that bothersome temperature variation in your water supply.

How to Fix It

  • When it comes to repairing a cold water sandwich, you have two options: building a recirculating system or installing a small tank water heater.
  • In fact, several manufacturers are already offering this buffer tank as an option today.
  • Add a recirculating system–also known as a return loop–to your tankless unit if you don’t want a large amount of hot water all at once.
  • This will eliminate the heat exchanger delay.

It’s vital to remember, however, that more energy is spent throughout the procedure.Do you have more substantial hot water requirements?By adding a small tank water heater to your tankless water heater, you may enhance its capacity and avoid the burst of cold water that occurs during use.

  1. The return loop is connected to the water heater by this connection.
  2. Because it just has a five-gallon storage tank, it is extremely energy efficient in operation.
  3. Never forget that a tankless water heater has an almost limitless capacity if it is installed and maintained properly.

Wrong Gas Line Size

The majority of tankless water heaters require you to (size) expand your gas line in order to ensure an adequate supply of gas. It’s possible that you’ve previously done this and your water is still flowing hot and cold. If so, your line is the incorrect size. It may be necessary to upgrade your gas meter in order to guarantee that your water heater receives enough fuel.

How to Fix It

The diameter of the line used for a tankless water heater should be between 1/2″ and 3/4 inch in diameter. For gas line replacement, contact a Service Experts Heating & Air Conditioning Expert if yours is too tiny.

Improper Plumbing System Crossover

  • Tankless water heaters require a direct connection to the supply and return lines in order to function properly.
  • It is possible for cold water to infiltrate into the hot water line when the plumbing was done incorrectly or when a pressure balancing shower valve has to be repaired.
  • This results in the hot water becoming tepid.
  • The hot and cold water will come in bursts until the line heats up after a period of consistent use.

It might be tough to diagnose this problem on your own, without the assistance of a trained professional plumber.

How to Fix It

  • When it comes to repairing a plumbing system crossover that isn’t working properly, you have two alternatives.
  • You have two options for adjusting the temperature of your tankless water heater: increase the thermostat or add a pressure balancing valve.
  • If you choose to raise the thermostat, you will be forced to utilize hot water from every faucet on a continuous basis.
  • Slowly raising the temperature of your hot water supply will allow it to heat up in your return line, which will benefit you.

If you elect to place a pressure-balancing valve in your gas line, the valve will keep track of the temperature of the incoming gas line to your home.It will also balance out any extra pressure that occurs when cold water enters the system, preventing you from experiencing bursts of hot and cold water at the same time.

Broken Flow Sensor

  • A faulty flow sensor might cause your tankless water heater to alternate between hot and cold operation.
  • The flow sensor monitors the amount of water entering your system and transmits that information to the control board of your unit.
  • If there is a sudden rush of cold that enters the system, the controller adjusts the flame accordingly.
  • This guarantees that you have enough hot water for everyone in your household straight away.

How to Fix It

It is necessary to determine the cause of the injury. Gas pressure, thermostat, and the water heater component of your system should all be checked for problems. Service Experts Heating & Air Conditioning can repair your tankless water heater’s flow sensor if it becomes faulty. This will ensure that your tankless water heater operates properly.

Dirty Water Filter

  • The water filter installed on the cold water input of instantaneous (tankless) water heaters extends the life of the heater and helps it to operate more efficiently by catching (sediments), calcium, lime, and iron in the water.
  • If it becomes too soiled, you may not only experience unexpected spurts of cold and warm water, but your natural gas cost may also spike as a result.
  • If there is an excessive amount of mineral building in your tankless heater, you may need to descale it.

How to Fix It

Replace your system’s filter on a regular basis to ensure that it is operating at peak performance. We recommend that you do this approximately every six months or so.
