Back in traditional days, it was very difficult to avail warm water for bathing especially during winters. But, with the advent of technology and electricity, geysers were invented to wade of the trouble of getting warm water. Ever since then, geysers have become a necessity in every household.
A water heater provides fresh and warm water for a refreshing bath.
A hot water bath is also known to kill all the bacteria residing on your skin surface and make you feel fresh and revived after a tiring day.
A warm water bath is also known to provide good sleep at night and hence a geyser is a necessity in one’s bathroom. Check out the best geysers for home use here.
If you plan to get a geyser for your household, here is a detailed guide on the different types of water heaters as we help you clear the confusion on the various types available in the market.
Types of Water Heater: Explained
Generally, there are various types of water heaters but we mention the 5 most significant types that are used on a commercial basis. We give you an in-depth explanation of the same.
1. Tankless Water Heater
Tankless water heater mentions that it functions without a tank and works for a large capacity of heating. It can heat the water in an instant and is very quick and efficient. Hence this type of water heater is installed in most households these days.
There are various heating capacities available and if you are planning to run the tankless water heater on electricity, then you will require to increase the electrical capacity of your household for the water heater to function appropriately.
This may lead to a rise in the electricity bills but will heat the water quite quickly and efficiently.
A tankless water heater may not require much maintenance but you will have to get it cleaned at least once in a year to avoid corrosion of the pipes and connections. These parts are too tiny and delicate to handle and hence their cleaning might be a challenge.
Appropriate cleaning and maintenance will help the geyser last for a good 8-10 years. The best part of the tankless water heater which makes it an on-demand product is its instantaneous water heating capability that gives you piping hot water right in a jiffy.
However, if you are looking for something in a larger capacity, it might consume more electricity which will lead to additional costs.
2. Traditional Storage Tank Water Heater
The storage tank water heater works like an insulated thermos that heats the water and stores it in the tank having a particular capacity. The capacity of the tank helps in determining how much warm water do we have for stored and ready for use. These types of conventional water heaters come with 2 valves, one for controlling temperature and the other for controlling the pressure.
The temperature and the pressure control valves work differently with the temperature control valve being released from time to time once you need to release a certain amount of heat for moderating the temperature level. The water can reach up to a maximum temperature of 120 degrees Fahrenheit. The pressure control valve works by releasing the pressure and reducing the pressure once it reaches 150 psi.
The only issue you might probably face with these type of water heaters is the storage as more the number of people at home, you would require a larger space in the bathroom and a larger storage tank.
Maintenance involves cleaning the internal parts regularly to prevent corrosion and enhance the lifespan of the water heater.
The dirt and sediments will include minerals and other types of deposits which need to be cleaned and replaced regularly. The good thing about these storage traditional types of water heater is that they are easy to maintain and install.
In terms of the cost, they are affordable. In terms of efficiency, the water heater performs well but is quite slow as it will refill up to the given capacity and only then heat the water which makes it very time-consuming.
3. Condensing Water Heater
Condensing Water Heater is the smartest of all water heaters and is also very energy efficient as it uses the surrounding temperature to heat the water. A condensing water heater is a great option for those who use natural gas resources. The water heater is capable of extracting energy from natural gas sources and use it for absorbing energy and heating the water within the tank.
This energy tends to pre-heat the water which then enters the boiler. This also works as a tank storage system just that the heating procedure within the tank is a lot more different. It heats by using the heat around you. Usually, the base of the water heater has heating coils.
The gas expelled at your home through natural gas sources is absorbed and the coils help in the heating of the gas which in turn heats the water that passes through the cold-water inlet giving you resourcefully utilized warm water at all times.
The maintenance of the condensed type water heaters is not much, it is very similar to the other types. Just that the gas exchange pipes can get choked up due to pollutants and needs to be cleaned regularly.
If you have a large family or too many members in your house, then the condensation type is very cost-effective as it usually comes with a large storage tank for exchanging the gas and capturing the heat. However, for houses that do not use natural gas as their source of fuel, then the condensing type water heaters are not very effective.
4. Heat Pump Water Heaters
Heat pump water heaters work on a hybrid system and do not exactly make use of electricity. Instead, they have a dual way of working which helps you save up on costs for heating water as well.
Here electricity is used only when the heat has to be captured and transferred into the water tank to warm the water. It has a very unique mechanism and uses electricity only for the basic purpose of transferring it to the water.
It consumes 60% lesser energy as compared to other types of water heaters. However, the space required for its installation is more, so you would need approximately 10 feet of distance from the ground to the ceiling for installing these types of water heaters.
Here, the heater does come with a tank for storage and regular maintenance involves cleaning the tank and the geyser model once in 6 months.
The plain advantage of having this heater is that it consumes very less amount of electricity for transferring purposes which makes it very cost-effective. However, when it comes to efficiency in functioning, the water heater may not work efficiently as it tends to absorb temperatures from the surrounding.
If the ambient temperatures usually remain cold, then the machine is almost useless. And since it involves such a unique mechanism, the machine setup is very costly as well.
5. Solar Powered Water Heater
This is the most conventional and cost-effective method of water heating. If you have ample space at your home, then you can easily set up solar panels in an open backyard or terrace where there is enough sunlight.
These solar panels comprise solar cells that absorb the heat energy from the sun and slowly transfer all the heat through a closed-loop system. This closed-loop has a heating fluid which is an anti-freeze fluid that transfers to the water tank to heat your water.
This system also works great for places that mostly have high temperatures and warm ambiance. Here, you would need to maintain the solar panels and the tank which is used for storing the water. However, for winters and rainy seasons when you will not receive ample sunlight, you need to have an alternative energy source like electricity or natural gas.
The advantages of using a solar-powered water heater are that you are contributing towards the environment, saving up on electricity bills and non-conventional energy sources and you can keep getting an unlimited amount of hot water in sunny weather.
However, the major drawback is the investment you make on the solar panels. Secondly, despite having solar panels, if you still need to have an alternate source of energy, then solar water heaters add up to your budget and is a futile investment.
Choosing a water heater is not easy. It requires you to understand a lot of technical aspects regarding the coils, the heating mechanism, and the various features that a water heater can offer like cost-effective, efficient heating performance, etc.
Our guide on the different types of water heater will help you drive the confusion away and aid you in choosing the best water heater as per your suitable requirements.
