Because of technology, human lives have become more convenient and easier, from the field of communication and transportation to even small things like cleaning and cooking to our homes. Likewise, because of these innovations–heating water for domestic utilization have become more accessible to humans.
As we traced back to history, our ancestors have been using fire woods, stoves with metal vessels like kettles to generate hot water. This technology of water heating has been proven to become less effective as for using more effort and energy obtaining less gain, thus lower efficiency. That is why as decades has gone by, new technology has driven and the traditional way of water heating was replaced by water heaters powered by fuel or electricity supplying hot water not just to a family but an entire community.
In this page, will will examine the importance of water heaters,might as well how they worked, common problems with water heaters and fixing as it needs them. This will also looked upon it’s integration upon HVAC systems and how it had helped numerous of people and communities through it.
What is Water Heating Technology?
It is a thermodynamic process that uses an energy source to heat water above its initial temperature.In homes, common uses of hot water includes cooking, cleaning bathing and space heating. It is often incorporated with HVAC systems to become more efficient saving energy at the same time attaining a greater output.
Thus, these water heating technology is also used in multiple industries as as source for steam and hot water as needed upon their processes.
Types of water heater
a.Conventional Storage Water Heater
-the most common type of water heater that holds 30-80 gallons of water. This type of water heater is insulated and usually powered by fuel oil and electricity. It comes up with many sizes and could be used any time, 24 hours a day.
-administering periodic and regular intervals can improve the performance and efficiency of the heater. Significantly, prolongs life of water heater. Tasks include the following;
a. Draining and flushing the water heater twice a year to eliminate built-up sediment and minerals.
b. Testing the pressure relief valve to ensure it is in good working condition.
Before the works starts, make sure to turn off the switch for power supply or set the gas switch to a pilot position.
b.Tankless (or Instantaneous) Water Heaters
-the tankless variety promises significant energy cost savings, because it heats water only upon demand. The only thing is that these tankless heaters flows at constantly low rate (approximately 2-5 gallons per minute). That’s why it is used only for domestic purposes.
However, it’s longetivity extends to 20 years as compared to conventional heaters with 15 years life span.
Hire a licensed plumber to flush the unit regularly (at least once a year) to eliminate accumulated mineral deposits.
c.Electric Heat Pump Water Heaters
-this type of water heater is powered by electricity where it works by intensifying heat as it draws from air that surrounds, transmitting heat to the water in the storage tank. This type of heater is efficiently three times as convenient as the traditional one and works best to those experiencing hot and humid climate.
For an electric heat pump water heater to operate at peak level, its air filters must be cleaned regularly. Otherwise, recommended maintenance is no different than with a conventional storage water heater.
Solar Water Heaters
-this type of water heater is powered by sun. This type of water heater contains limitless and free energy, though expensive than other known water heaters.If taken care properly, this water heater could lasts up to 15 to 20 years.
For maintenance of solar water heaters, one should note these things;
a.A regular cleaning of dusty or soiled collector
b.Monitoring the connections between a storage tank and its piping
c.Looking for damaged insulation covering pipes, ducts, and wiring
d.Checking the tightness of all nuts and bolts responsible for securing the collectors in place
e. In an active system, verifying that the pumps are operating properly
Common Water Heater Problems
1.Water Heater Leaking
-if there is a water leaking in the bottom of the water heater then it means there is a crack in the internal tank and the water heater should be replaced.If a leaked developed from the top, this is usually cause by piping or fitting malfunction.Otherwise, it should be replaced.Thus, the following should be done;
a.Drain the water heater
b.Turn off the switch and valve immediately.To turn off the valve, just rotate it clockwise to shut off the water flowing through the house.
2.Water is emptied out or it does not produce hot water
-The first thing you should take note is the type of water heater since every water heater differs significantly.Then if,
Gas Water Heaters
This usually means the pilot light on your water heater has gone out or your water heater has a malfunctioning part. As a solution, try to relight the pilot and if not, call the authorities to help repairing it.
Electric Water Heaters
-If you have an electric water heater and you are not getting any hot water, it’s possible that your breaker may have tripped or the water heater has a faulty thermostat. It’s a good idea to check your breaker box to see if the water heater breaker has tripped. If the breaker is in place most often a water heater part has failed.
3. Water Heater is Noisy
-A noisy water heater could mean an accumulation of sediments in the bottom of the tank, meaning it needs to be drained . A high pitched noise can be the result also of high incoming pressure.This can be a problem and should be diagnosed and repaired as quickly as possible.
4.Hot water is too hot
-If turning down the thermostat’s dial, won’t solve this problem then one should do the following;
a.check the water heater, if you hear boiling sounds inside the water heater then the appliance may not be shutting off as it’s set temperature.
b.check the temperature-pressure relief valve if it is improperly installed or malfunctioned.
c. if yes, then turn off the heater and replace the temperature-pressure relief valve.
4.Hot water is Discolored or Smells Bad
-if it smells or discolored, then the source of water or the water itself could be the root of this problem.If both hot and cold water or cold water smells, then likely the source of water. If discoloration occurs, then check the water heater for any corrosion of iron or metal.If otherwise, consider installing a water softener or filter.
