Cold mornings call for warm showers as they instantly activate the entire system and makes you ready for work. Ever wonder what goes behind the scenes, how does a geyser work to get you that warm shower every morning. Here’s everything you need to know the functionality that goes into it.

To begin with, let’s start with the parts of the water heater.  The first and the most important part is the “Tank”, it’s an inner tank, made of steel which is lined with a glass coating, abrasion-free. It can hold around 40 to 60 gallons of water.

The next part of the heater is the “Dip tube”, it’s generally placed at the top of the tank from where it enters the heater and goes through the bottom where actually it’s heated.

Our next component is “Shut-off Valve” which is placed above the water heater which helps in stopping the flow of water into the heater. The other important part of the delivery pipe which is generally located at the top of the tank and it helps to let water flow out.  The “Drain Valve” is located at the bottom of the exterior.

It helps in emptying the tank easily by replacing the elements by removing the sediment by moving the tank in the other location. Then comes the “Thermostat”, it’s a switch that senses the temperature and closes off the temperature that falls and opens up if the pressure of water exceeds.

The heating mechanism heats the water inside them, the gas water heaters come with an additional burner and chimney system. The “Pressure relief valve” helps to keep the water pressure in the limits.

The sacrificial anode rod is made of magnesium or aluminum with a steel core to help in providing the utmost resistance to corrosion.

These all were the essential part which works behind inside the water heater. Now, let’s explore a bit about different types of water heaters and how they function.

The first type is the “Tank Type Water Heaters”- The specialty of this heater is that along with heating water, it stores the same. The water and delivery pipes are placed on the top of the tank. With the help of a dip tube, cold water is directed to the bottom of the tank. The water is collected through the hot water delivery pipes from the top and outflows the hot water.  Water heaters are generally equipped with a T&P valve, which is opened when the pressure of water heater helps in exceeds the pre-set limit.

These tanks come with a magnesium anode rod which provides maximum protection against corrosion. Such tanks are made of steel along with a glass lined to keep corrosive elements at bay. Such anode rod starts corroding in the place of steel. Though, the tank needs to be interchanged once the magnesium anode is oxidized.

The next type is the “Electric Water Heaters” – These heaters generally operate at a 220 V. The current is passed through the electrical resistance heating element to heat the water. These heating elements are placed in the tank, one at the bottom and other at the middle of the tank.

With the help of a thermostat, power is transmitted.  A thermostat switch is usually used to sense the accurate temperature of the water. When the temperature increases, it sets the temperature and when it falls, it simply closes to allow the flow of current.

Storage Geysers

These types of geysers come with inbuilt storage tanks, which hold the water for heating.  The water heater helps to outflow from another pipe which is placed at the top.

Geysers come with a different storage capacity, the water stored in the tank loses its temperature that’s the one thing which is not appealing about these geysers.

Appreciated water heaters are effortlessly obtainable on the Internet if you’re on a budget.

It is also tough and has a well-engineered design that will help you offer best water heating solutions for years to come.

What is the function of an electric heater?

The electric heaters are deposits of hot water for sanitary use. To operate they only need to be connected to the sanitary water network and plugged into the grounded power. They differ from gas heaters in that water does not instantly heat up when passing through the appliance, so they cannot offer unlimited hot water.

Luckily, there are a variety of different models on the market that are capable of accumulating and heating water to satisfy the water consumption of all types of homes.

Common Gas Water Heater Problems 

  • As regards the second problem with which you can find yourself saying that it is known as the fluctuation of hot water temperature. The water usually comes out much colder if the heater has not been used in a while, as you can imagine, it is a much more common problem in second homes to which it goes from time to time. And is that the heaters, after long periods of inactivity, do not detect changes in water temperature so quickly and accurately. However, it can also cause the reverse process and in the end, the water ends up burning more than it should. So the solution will be to change the gas valve, something that will only be worth it if the heater does not have too much time. However, it is best that you consult with our professional plumber and ask him/her about the budget of both options since only then you will be able to see if it is worth or not worth opting for one decision or another.
  • Another most common case happens because you have the hot water ready but only at lasts a few minutes, which translates into a problem of pipe conduction. As we say, this will happens when you see that only a jet of hot water comes out and then cold.

How to choose the right gas heater for the home

If you are looking to buy a water heater, decide to choose the most suitable one according to the needs of the house and for that you must take into account several factors, such as the use that is going to be given, the place of the house where install the thermos and the hardness of the water in the area where the house is located.

Below we explain the characteristics that influence when choosing a water heater and a guide to know which one to choose.

Capacity of the thermos tank

The water heaters heat the water that is in your tank through a resistance. When the accumulated water reaches sufficient temperature (around 60 degrees Celsius) the resistance is turned off and the water remains inside the tank until there is a demand from the user. Water, unlike gas heaters, does not heat instantly when passing through the appliance. That is why, before making a purchase, you must calculate the capacity that is necessary.

When choosing the capacity of the flask we have to calculate the daily amount of hot water that we will need. We will also have to take consumption habits into account: for example, if all members of a household take a shower at the same time, we will have to choose a thermos with a deposit able to meet that peak demand.

Consumption distribution

If the showers happen in a continuous way and not in intervals of about 2 or 3 hours, we must take this fact into account because the above will vary.

You should also take into account the hot water cost of the dishwasher and the washing machine because if the appliances are very old they can increase the cost.

Members of the family

Each person consumes an average of 30 liters of hot water per day. So for a house where two people live, a 50-liter or 75-liter electric water heater would suffice for the use of a sink, sink and shower. If instead of a shower, there is a bathtub, better to choose one of 80 liters.

When the family nucleus is composed of more than three members, the capacity of the electric boiler must range between 100 and 200 liters.

So buy that water heater which fulfills your family requirement
