What is a Water Heater?

From a layman’s perspective, a water heater is an electronic device that warms up tap water, which then makes its way to either washing utensils or bathing.

Most people don’t realize the full potential of their water heater. When you wake up in the morning and turn on your hot shower, you’re actually enjoying quite a few benefits that your water heater has provided.

You may not think that you need a water heater, and it’s true that you can get by without one. However, they offer a lot of benefits and can save you a lot of time and money.

How does a Water Heater work?

A water heater is a mechanical system that is used to heat water. Most hot water heaters are able to store hot water until the tap is opened. When you turn on the faucet, cold water enters the tank. This machine converts energy into heat and produces hot water for use throughout the house.

What are the types of Water Heater?

A water heater is a tank-type appliance that stores hot water and supplies it as needed. Water heaters are usually located in an indoor space near the point of use and are operated by electric or gas energy.

Water heaters can be fuelled by gas or electricity and they usually come in two different types: storage and instant. Storage water heaters keep a reserve of hot water on hand at all times and provide hot water as needed, while instant water heaters heat water as it is needed. The storage heater houses above 15 litres of water whereas the instant version of Indian geysers can store up to 10 litres of water.

The capacity of the heater varies depending on the use and we have here the 10 best heaters.

With 100’s of brands and models available in the market, it becomes daunting to find a perfect water heater for your bathroom or kitchen. That’s why we’ve put together this blog showcasing the top 10 best water heaters in India.

The above products all come with their own benefits and specifications. When selecting a geyser, you should always keep a few things in mind.

1. The number of people in the house who would use hot water.
2. The space in your bathroom and the ceiling height. This could help you decide between a horizontal or a vertical geyser.
3. Zero in on a budget that you have for this device and accordingly search for the right product. Once you have your research in place you can adjust a few rupees. 
4. The power supply in your house and the amount of power you wish for your device to consume
5. Lastly, keep in mind the location you live in. Find out the availability of a service center of a particular brand in your area. 

Once you have all these things in place you are free to select the product that suits your needs. We would suggest a 15 liters heater for a family of two adults and one child. However, for a larger family going for a 25 liters geyser would make life easier. 

How long do water heaters last?

How long your water heater lasts depends on the quality of the water heater, how frequently you use it, and your water quality. If the water heater tank is made of copper then it can last anywhere from 5 to 20 years. If it is made of steel, then it will probably last 5 to 10 years.

Most modern water heaters are built with replaceable parts, which means you can replace worn or damaged parts instead of buying an entirely new water heater. However, water heaters are prone to corrosion. Blocked or slow-moving water flow can damage your water heater by allowing rust to build up inside the tank.

However, water heaters are prone to corrosion. Blocked or slow-moving water flow can damage your water heater by allowing rust to build up inside the tank.

What are the most common problems with water heaters?

Rusting of hot water heater tanks is a common problem that makes them brittle. Water heaters are generally unsafe to repair, requiring you to hire a professional to fix them.

Overheating is the second most common problem with water heaters. It often results from a faulty thermostat or a blown fuse. In case of a thermostat problem, you have to replace it. In case of a blown fuse, the easiest way is to replace it with a new one.

The third most common problem with water heaters is limescale build-up. It can cause a lot of problems. The most commonplace for limescale build-up is the heating element. Limescale is formed when hard water with high calcium content is heated. The water evaporates and the calcium compounds are left behind. These compounds are very hard and they bond together to form limescale.

Additionally, water leaks are another common problem with water heaters. The water constantly stays in the tank and eventually corrodes the tank to create minute cracks from where the water starts to leak.

What are the signs of a water heater going bad?

In most cases, your water heater will begin to make a loud gurgling noise when it’s failing. If you hear this, call a plumber immediately. This means the tank is almost completely empty.

Another sign is a water heater that takes a long time to reach a comfortable temperature in your home.

If you find discolored hot water, your water tank may have rusted and you may need to replace your water heater.

How do water heaters fail?

Water heaters usually fail due to one of two reasons: corrosion and sediment.  Corrosion occurs when water with dissolved minerals such as calcium and magnesium react with the metal components of the water heater. If left untreated, this corrosion can cause scale buildup and reduce the heater’s efficiency.

Sediment, otherwise known as limescale, is a build-up of minerals such as calcium, magnesium, and iron. Sediment can clog the water heater and reduce its efficiency and can be a fire hazard.

The third reason for a water heater to fail is the burned element. The next common failure is where the thermostat has failed and the pilot light is out.

Why do water heaters explode?

As the water in the storage tank gains temperature, the pressure within the tank increases. If the temperature of the water goes higher than the temperature of the walls (the temperature of the water is lower than 150 degrees Fahrenheit, and the temperature of the walls is lower than 130 degrees Fahrenheit) then the tank might explode.

When the temperature of the walls is lower than 130 Fahrenheit, the tank is said to be in a “Thermodynamic Explosion Region (TER).” The pressure in the tank will increase until the temperature of the tank and the temperature of the walls matches. Sometimes the gas valve is faulty. Other times the pilot light goes out. And of course, water heaters can explode if there is a gas leak. If your water heater is more than 10 years old, it’s a good idea to have a professional check it out now and then to make sure it’s safe.
