Electric Water Heater: Electric Water Heaters

This type of water heater uses electrical energy to heat the water. Water heater electric energy is also divided into two types, which use tank (storage) or who does not use a tank (tankless). 

1.-made electric water heater tank (Storage - Electric Water Heater) 

This type of electric water heater uses a tank to store hot water before use. Characteristics cylindrical horizontal or vertical, and because they are large enough and eating places, usually mounted outside the bathroom. And the water in this tank is heated until it reaches the desired temperature. Components and how it works looks like the next picture. The main components of this tool is an electric heating element that is located at the top and bottom of the tank. When the incoming cold water to the tank, the heating element heats the water began to work in the tank until it reaches the desired temperature. And when the water temperature in the tank begins to fall, to two heating element heats the water is working again until it reaches the temperature that has been set up. With dimikian water temperature in the tank is always awake and always available every need. Therefore, use an electric water heater tank is more wasteful electric power consumption. Electrical power continues to be sucked to maintain stable water temperature in the tank even if no one is using hot water. Here's an example of Amazon's Reliance brand products with a capacity of 6 gallons.

wearing Tank	without Tank
Size: Large dining spot	Small, do not eat the
Electricity: power consuming, work continues	More efficient power, work when needed
Price: Expensive	Cheaper,
Availability of hot water: there is always a	Want hot water? wait first
Suitable for large families	Suitable for small family

For this second type that does not require a tank. So the water does not need to be accommodated first. Just like a gas water heater without a tank, electric water heater without a tank of this new work heats the water when the water faucet is opened. The water from the faucet indirect heat, it took a while to get hot water is desired. Long wait for it depends on the size of the appliance watts of electricity. The greater the wattage the faster its hot water out of krannya, and vice versa. 
How it works the same as a gas water heater without a tank. When the faucet is opened, water flow is detected by a water flow sensor (flow-switch) and activate the heating element in the heating module and heat water to the desired temperature. After reaching the desired temperature or turn the faucet on (flow switch does not detect any water flow again), the heating element was automatically dead. So just when it needs it works. Thus more efficient power consumption, although no hot water available at all times. Must wait for the first few moments after the tool works. Here's an example of its products.
conclusion:

Solar Water Heater: Solar Water Heater

If a flat installation, installation of this equipment still had to be tilted to the position of the storage tank is higher than the collector panel, as shown below.

Water heater or water heater seems to have become a way of life in urban areas. In addition it is very comfortable warm bath when the body is tired after a long day of work, in certain circumstances it is necessary for elderly family members or affected by arthritis or who are allergic to the cold. Characteristics after afternoon showers often sneezing like flu symptoms. One solution yes evening wear warm water bath. 

Traditionally to get hot water, enough water to cook with the stove. Then masalahpun appeared, long wait until the hot water and the amount of hot water obtained is also limited. The more water that is heated, the longer the wait for him and certainly the more fuel is needed. 

On this basis (time-quantity-energy-costs), the presence of water heating technology of choice. Quite a lot of brands of water heaters in the market with various features offered. However, according to our observations above are not all problems solvable by existing brands and types. In other words, each brand and type has advantages and disadvantages of each. For the moment we try to discuss the first type of solar water heaters, Solar Water Heater. 
Based on how the system is used, the solar water heater is divided into two types, namely: 
1 solar water heater system is passive 
2 solar water heater system is active 

1. passive - Solar Water Heater: passive solar water heater 

As the name implies this type of water heater uses sunlight as energy to heat water. Said to be passive because this type does not need another energy in the hot water production process. In other words 100% rely on solar energy. 
This type of water heater comprises two main components, the collector panel and storage tank, which is connected by two pipes. In the collector panels are glass cover that functions capture the sun's heat circuit arrangement in which there is a copper pipe as the water lines are wrapped with heat sink fins (absorber). While the tank acts like a thermos of hot water in order to accommodate the long-lasting heat.


How it works, as seen in the picture above, when the sun is shining, the collector panels capture sunlight and mechanically transferring heat from the heat sink fins to copper pipes filled with water, so that the temperature of the water in it slowly increased. Warmer water will move up into the storage tank and the colder water will come down into a series of copper pipe to be heated. So on moving water itself until all the water in the storage tank reaches the desired temperature. When the temperature of hot water in the storage tank is equal to the temperature of the hot water in the collector panel, with its own water stops flowing. 
There are of interest here, namely the water hotter and colder water continues to circulate without outside help, such as pumps. This can happen because the water is heated to expand and cause the masses of its kind to be lighter than the density of water so that the water cooler the more heat will move up. This is called the principle of natural convection of water due to heating, and systems based on this principle is called Thermosiphon system. 
Therefore solar water heater with this Thermosiphon system, installation is always on the roof of the house. In addition to getting enough sunlight, the slope of the roof used to position the storage tank is higher than the collector panels.

2 Active - Solar Water Heater: active solar water heater 

Just as solar water heating system is passive, solar water heating systems utilizing solar energy remains active for the water heating process, only for the distribution of hot water and the cold water still requires electricity to drive the pump and the automatic control device.



Solar water heating system is active, is designed for the purpose of hot water in a large scale, such as hotels, spas, hospitals and apartments. Therefore these active systems require more complex support components and the capacity of storage tanks are much larger. 

In special conditions / emergency, such as rain or overcast weather days, while the demand for hot water has increased, the system is equipped with an electric energy water heater, gas or heat pump as its emergency backup. Following the scheme of this type of system is fitted as an emergency backup heat pump her.

Gas Water Heater: Water heaters using gas

In this post we try to write the type of water heater that uses gas as the energy needed to heat the water and called the Gas Water Heaters (Gas Water Heater). 
This type of water heater is quite popular in the community, in addition to the price is much cheaper, also the size and shape that simple. 

Popularity of this stuff in the community make manufacturers competing to produce this tool with our wide range of options for the 3 major groups, namely: 

1.-gas storage water heater. 
Using a gas water heater uses a storage tank. This type is usually used to produce hot water in significant amounts. The surplus of hot water available at all times. The drawback of the fuel gas to be more extravagant than that without a storage tank, because it works automatically to maintain a stable temperature in the tank stockpiles. Here's an example of the product images:

2.-Indoor-Tankless gas water heater. 
Using a gas water heater without water storage tank installed in the room. The opposite of the above gas heater. The drawback, no hot water available at all times. When needed (faucet is opened) is a new tool to work heats the water. But the waiting time is not too long. The surplus of the fuel gas is more efficient. Here's an example picture:

3.-outdoor-Tankless gas water heater. 
Using a gas water heater without water storage tank that is installed outdoors. Advantages and disadvantages are the same as No. 2 above. Here's an example image:

The workings of a gas heater is basically almost the same for all types. We take the example for the type of gas tankless water heater-indoor only. 
Basically, this type of gas water heaters is almost the same as the water we cook with a gas stove, the difference between this tool works automatically and the water is heated through the heating components called heat exchangers.

Here's how the makers of this type based on the picture above. 

1. we open the hot water faucet 

2 Cold water flows and detected by flow sensor 

3 Computer light the burner (which works like the stove) to memanaskanheat exchangers 

4 Cold water circulates through the heat exchanger 

5. Heat exchanger heats the water until it reaches the desired temperature 

6 When finished, when the hot water faucet is closed, and the water stops flowing, flow sensors did not detect any flow of water, then the computer will shut down its burner. And so on. 

Special gas water heater without a tank that is mounted inside the room (kind of a no: 2), this type of water heater is usually installed directly in the bathroom to make it more practical when you want to adjust the water temperature as desired. However, if the tool is installed in the bathroom, make sure the air vent in the bathroom is enough so that air can circulate properly. And if at any time there is leaking gas will flow out of the room immediately. 

To be safe, I advised gentlemen installing gas detectors near the water heater so that in the event of a gas leak can be taken. Due to the nature of this gas, do not look, no color and smell is not too overpowering especially if the leak is small.

It should be noted also problems chimney channel. Although not visible, the name is still burning produces carbon dioxide gas. Need to be given channel / special pipe out of the room so that the direct combustion of waste gases out of the room, such as the example shown below:

Thus, may be useful. Later we discuss the water heater that uses energy.

AC Water Heater: Water heater transplanted into AC

Using the air conditioner or water heater (AC [Air Conditioner] Water Heater) is a type of water heater that utilizes the heat energy generated by the AC. This is an innovation that is still fairly new for a water heater. With AC water heater requires no new additional energy to get hot water for domestic use, such as for example a shower. Not all types of air conditioning can be "grafted" with this water heater. Generally split type air conditioner that can be grafted, the windows are the type of air conditioning could not. 

The working principle of AC water heater. 
Earlier we saw how the first Split AC in general, as illustrated in the scheme below.

Air conditioner using Freon gas as a coolant. When entering into the Indoor Unit (evaporator) temperature is very cold freon. Cold temperature of the exhaled freon to cool the room. Room temperature the more heat will be exploited so that the refrigerant becomes hot when it came out of the Indoor Unit and Outdoor Unit so entered. Upon entry to the Outdoor Unit and before cooled in the condenser, refrigerant heat compressed (compressed) by a freon compressor so that the temperature is getting warmer again. Temperatures were very hot freon is cooled again by blowing fan condenser section. And freon back into the past the Indoor Unit expansion valve to reduce the pressure generated by the compressor. And so on. 

In Water Heater AC, very high temperature refrigerant coming out of the compressor is channeled to the heating element (heat exchanger) that is in the tank and heats the water that is in the tank, as shown the following scheme.

After the exit of the heating element in the tank heater, the temperature is not too hot and freon cooled condenser back in the Outdoor Unit. Out of Outdoor Unit cold freon back into the Indoor Unit to cool the room. And so on. 

So Tank Water Heater that has been specially designed for storing and heating water, in-the-graft pipeline after copper freon compressor, as shown in the second image above scheme. (1) Figure Scheme Split AC normal, and (2) Figure Scheme AC Split after grafted tank water heater. 

In conclusion, this type of water heater 100% dependent on the work of Split AC. How much quantity and quality (water temperature) hot water you get depends on how long the AC Split work continuously (on) and how big the tank heating capacity. 

In some cases the AC for household use, the reason the cost of electricity, the AC is only used at certain times, only at night when going to bed, for example. Effective air conditioner turns on only briefly, a few hours only. And result in the water heater is not working optimally, especially if a large heating capacity tank. 

To overcome this problem, manufacturers of this type of water heater has set many options heater tank adapted to the needs of the family. Starting from a wide selection of tank capacity: small - medium - large, up to the amount of its heat exchangers: single and double heat exchangers heat exchangers, using AC Split 2.

Double Heat Exchanger Tank - 2 AC Split - Wika

In addition there is also a double tank heater heat exchanger heat exchanger is one of its uses electrical energy as a backup when the heating of the air conditioner is not enough to heat the water in the tank.

TREATMENT WATER HEATER

WATER CONDITIONS healthy to bathe among other odorless, colorless cloudy with a soft particle entrainment (salt, lime, moss and sand) when the water does contain a metallic element which rapidly destroys water heater, that would be filtered or unfiltered water before entry into the heater tank. Do a simple test to determine the quality of your bath water to prepare healthy clear glass, open the hot water faucet Contain the water with clear glass was then observed, when smelling, cloudy or there are small particles like sand, lime, moss to take steps for holding maintenance of your water heater, water heater should treatment once every 3 months include electrical checks, drain the water tank, check the control valve, clean the body of the unit and to avoid electric shock should give ELCB although additional water heater is equipped with a safety from the manufacturer.
Do not wait for the new first held repair damaged, earlie lu. ewm do damage and inhibits the activity of care, identify the water heater to your shower though more easier to handle if there is damage. In general, the water heater that you use like;
1 Solar Water Heater (Solar)
usually has two power / energy is solar thermal and electric power I mean come the rainy season when the sun is almost blocked by the clouds, the electrical power automatically work to continue its work to maintain hot water
2 Electric Water Heater
Ø Using the tank / water tube (wait a few minutes depending on the heat content of the tank)
Ø Instant (water coming out of the shower can be used directly)
3 Instant Gas Water Heater
All types of water heater has the advantage of each but if not then the routine maintenance once held a similar problem arises, which is frequently encountered in general like;
· The water that comes out through the shower and faucet is not smooth as usual
This caused the water line entering the water heater can also be enclosed shower dirty sewage sludge as sand, moss, rust and lime. The way to clean the filter (the filter can also rounded wire attached to a black rubber seal is made of stainless steel or materials) shower is located at the end of the hose, while the faucet located on the water outlet, turn the loose ends left clean and reinstall is complete
· The water coming out of the shower and faucet is not hot
Using a Solar Water Heater heat collector elements are covered with clear glass sticking dust, rust or dried leaves in the wind. The way to clean glass cover collector, check to power (power failure or MCB ngetrip / down, automatic control 2 power does not function). Electric Water Heater, using tubes for specific use hot water quickly runs out, means having to wait several minutes to get hot water again with normal kelisrikan remarks. Instant Electric Water Heater, check to power (the power goes out or MCB ngetrip / down)
· The heat of halting water
Water supply to the tank water heater that has not as usual because there is usually a reduced water supply faucet wearer same reservoir solution to back channeled to the water heater when necessary use booster
Note: consult on these issues in their field and experienced technicians also fare better ask maintenance services.

5 SIGNS WILL BE BROKEN WATER HEATER

Here are 5 signs of water heater that is damaged and in need of repair: 
Changes in ordinary water into the hot water takes more than one (1) minute. Please check the other faucets that use the same machine, if required parentheses same time. And do not forget to also check whether the frequency the longer the time required each day. If all the answers are yes, just contact the experts because over time the water heater will stop producing hot water. 
Check the hot water, if you feel there is an electric shock. If yes, although minor, immediately turn off the tap and contact an expert. 
The flow of water out of small and short means there is a blockage. Contact an expert before it becomes very severe. 
When the tool started making a sound like the sound of the collision, cracking or other noise, you should contact the builder before late. The sound produced by a hard mineral unintentionally formed in the water heater appliance. 
The problem that often occurs is leakage. Water heater is very often out of water signifies it is time to call the repairman can fix it. 
The hot water smells issued. In each heating appliance, there is always the anode rod protect the water from corrosion (causes water to smell). When the water begins to smell means something is happening with the anode rod. Call an expert to resolve this issue. 
In the gas water heater, gas smell, but it is hard not turn on the water heater. In such cases, stop the hot water faucet open, as if constantly forced explosion will occur, when the lighter arrived - arrived responds. 
Lighters lit up, but the fire could not be lit at the burner. immediately contact professional. Because if forced to continue, could cause an explosion if gas suddenly out of heaternya. 
If the gas water heater hard on, immediately stop efforts to turn it on and you should contact an expert, very dangerous to tamper with without having adequate knowledge. 
Many people do not care about signs - these signs until it is too late so that the state of the water heater should be replaced with a new one. As the saying goes "Prevention is Better", not to prevent engine damage because the water heater issued price will be more expensive to buy a new heater.
