The article covers various aspects in detail to provide a clear picture to you.

Types Of Water Heaters

Once you decide that you want a water heater and look out for it, you will understand how vast the market is and how complicated making the choice for the water heater is. A layman doesn’t buy water heaters daily, so it is only fair that most of us don’t know about the water heaters in detail. The water heaters last for long, and it is not something you need to buy frequently. Let us take a look at the different types of water heaters available and their details in brief to understand the various options that you have:

Conventional Storage-Tank Water Heater

A conventional storage-tank water heater is the most traditional and standard water heater available in the market. It is this model that is used by most families around. The water heater comes with a tank which limits the water that can be heated at once. It heats the water and also keeps it warm throughout. This water heater must be kept on all the time to keep the water in the tank heated. It has two valves to maintain the heat within the container so that it is not under or overheated

Tankless Water Heater

The tankless water heaters are something that has come around with new technology and can give you an almost endless supply of hot water for your home. As the name suggests, there is no tank attached to this water heater, and it works on the principle of heating the water in a flash as and when you need it. It is due to this feature that it is also referred to as ‘on-demand water heater’ by a lot of people. There is no risk of running out of hot water in case of tankless water heaters.

Heat Pump Water Heater

The heat pump water heaters also come with a tank. What is different for heat pump water heaters is that they don’t directly use electricity to generate heat, so there is less running cost involved. The temperature in this water heater is created using the heat in the air or on the ground, and the electricity is only used to move the heat from the air to the water or from the field to the water as the case may be. This is a good option for people who like energy savings options.

Solar-Powered Water Heater

As the name suggests, the water heater operates from the heat extracted from the sun. This heater can work if you have solar panels or are considering installing them. These are also a good option only when you stay at a place where the climate is warm and sunny, which can be used to run the heater. The heater contains a heat conductive material as it’s the heating element which is heated using a closed-loop system which then heats the water. The solar water heater is the most energy-efficient and environmentally friendly of all water heaters.

Condensing Water Heater

The condensing water heater uses the unused gas fumes at your home to heat the water. The option is an ideal fit if the primary energy factor at your home is natural gas, and you have convenient gas lines around. The water heater contains a tank like the conventional water heater, it has a coil at the bottom, and the heated exhaust from the natural gas is funneled through to the coil which eventually heats the water. As evident from the method, very little energy is used to heat the water apart from the gas fumes which are already used.

Type Of Tankless Water Heater

While we checked through the various types of water heater above, there are inner parts for the tankless water heaters as well. The tankless water heaters have evolved with time, and there have been a lot of innovations that have been initiated in each of their features to make them better. They have improvised to suit the needs of the region with each new invention. Let us take a look at the type of tankless water heaters to understand them in more detail:

Non-Condensing

The non-condensing tankless water heaters are the very first generation of the tankless water heaters and have been around for quite long now. These have been established and highly used in the Japanese and European regions with significant satisfaction amount of people. These tankless units use the heat exchanger to heat the water as per your demand and reach the desired efficiency factor. The plus point for these units is that they have been widely used, tested, and recommended, so they make for a very reliable choice.

Condensing

These were the next innovation and belonged to the second generation of the tankless water heaters. The addition to this heater is that after the initial heat exchanger, they use a second heat exchanger which reuses the heat from the exhaust to do the further heating. It means increased efficiency of 90% almost. The units can be vented using readily available PVC. However, you will require to incur a higher unit cost. These are not good for short draws of water like for washing your hands.

Hybrid

These are termed as hybrids condensing water heaters because they find a midway to overcome the drawbacks of the above two mentioned water heaters. These were invented in America and contain a small tank which is used to store heated water just enough for the short draws which cannot be done through the usual tankless water heaters. It means these will provide efficiency of condensing water heater and have a small tank to overcome the problem of short draws.

These are the three basic types of tankless water heaters with their specifications mentioned. You need to understand which would prove to be the most useful and convenient to you and your family and then decide the best tankless water heater.

Tankless Water Heaters Vs. Storage Water Heaters

This has been an age-old question ever since the tankless water heaters have been introduced to humans. Everybody needs analysis of what needs to be chosen and why. When we decide to spend the money, we want our money to be put to the best use and in the best available option. Below is the factor-based distinction for the two types of water heaters which can help you choose a better one based on what is important to you individually:

Cost

Cost is a significant determining factor for everyone in all the decisions that you take. Buying a water heater is not frequent so you would want to spend it thoughtfully and also consider the cost after it has been purchased.

Storage water heaters: The purchase and maintenance cost is less as compared to tankless water heaters. However, they use up more energy than the tankless water heaters and hence can cost high running costs.

Tankless water heaters: The buying cost and even maintenance can be higher than the storage water heaters. However, they save the price on the energy used up so that it can be a good save on the whooping opportunity cost.

Life

When you purchase something, you look for the experience and durability of the product so that you don’t need to buy it any time soon again. The water heaters generally have a good life span. However, it differs between these two types of water heaters.

Storage water heaters run for a good life span of 10-15 years and do not usually have replaceable parts, which mean they need to be scrapped once they stop working nicely.

Tankless water heaters run for a more significant life span of 20-30 years, which is almost 10-15 years more than the storage water heaters. So the next model will not be purchased for a longer time, and that also saves them money in the long term.

Size

Size plays an essential role in a lot of people. While some people might not have the space for some water heaters, others might have space but would choose to go with a compact design. It is a subjective choice of the buyer through and through.

Storage water heaters take up more space. They come with a storage tank, and that also needs to be placed along with the water heater, so if one has a smaller space, this might not be a viable option at all.

Tankless water heaters are newer and very compactly designed. They don’t have a large space requirement and can be chosen by people who have space constraints.

Energy

The cost of running the equipment is also as long as the life of the material, and that cost must also be considered while comparing to get a bigger picture. There is a difference between the energy and time consumed by both the options as below.

Storage water heaters take a longer time to heat the water and need to be kept on throughout the day to keep the water stored in the tank heated. They use up more energy and result in higher energy bills.

Tankless water heaters don’t use much energy. All the tankless water heaters reviewed have shown to use around 25% lesser power as they take less time and don’t need to be kept switched on. Therefore they are more efficient in energy savings.

The above comparison clearly shows why the best tankless water heater is a much better and more practical choice for most people and the benefits attached to choosing it.

Benefits Of Tankless Water Heater

The pointers mentioned above clearly indicate why and how choosing the tankless water heater is a better option as compared to the other types. However, there are also many specific benefits attached to the best tankless water heater which should also be brought to your notice so that you can understand why should you make this choice and how is this choice better for your easy and comfortable life:

Durability

A tankless water heater lasts for a long time because it has high efficiency and sustainability. You can rest assured about the longevity of the tankless water heater because they have a good life span that can free you of worries for almost 20 to 30 years after you have purchased a good one after a lot of consideration.

No Cold Showers

The biggest and yet the essential benefit from a tankless water heater is that you won’t need to take cold showers anymore. Not just you, the tankless water heater provides for the showers of your entire family and household as it allows for hot water on demand as and when needed by anyone around your house without a tank limit on water.

Multiple Activities

Water at the house is not needed only for showers. At cold places and in winters you cannot use cold water for any of the events. The best tankless water heater can provide hot water for washing the dishes, cleaning the house or for another house chore without interrupting the shower time or other water uses by others in the house.

On-Demand Water Supply

Another visible and tangible benefit is that the water is supplied on demand by the tankless water heater and in a flash as and when needed. In case of the storage water tank, you can use hot water only until the tank allows it, post which you again need to wait for the container to be full and hot which takes a good half hour or before you can use the boiling water. Tankless water heater eliminates this inconvenience.

Water Conservation

The water is also saved in case of tankless water heaters. The storage water heaters heat the water and fill the entire tank whether tank as the whole is needed or not, which is an evident wastage when all you need is a small draw of water. In the case or tankless water heater, you only heat the water as and when you use it, and there is no wastage whatsoever of the water resources.

Quicker

The tankless water heater heats the water in a flash, and you are good to use it as soon as you turn it on. In case of a storage water heater, first the tank fills the water for around 10 minutes, and then the water is heated for about 20 more minutes. So the water is only available to use 30 minutes after you start the process, which is not an ideal scenario for someone who is in a hurry.

Cost-Saving

Overall, having a tankless water heater is more cost-effective than a storage water heater. The heater lasts longer, it also uses less energy, and both these cases save you a whooping cost as compared to the storage water heater. You also don’t need to keep this running all the time to maintain the water hot, which is one of the best savings of energy bills for your house.

Compact

Gone are the days where we were provided with large devices and equipment which took up most of the space in our house, and some couldn’t even buy those due to space constraints. The best tankless water heater is small, compact and of good design. The new electric models are thin enough to fit any of these places without much ado. They won’t take up colossal place and nor would they appear to ruin the aesthetic of your house.

Purer Water

Nothing is important than health. Good health benefit trumps all other interests. The tankless water heater also provides purer and better water quality for your use. In the case of storage water heaters, the water is stored in the tank. Older the tank, higher the chances of water getting rustier and impure. This is not the case with the tankless water heaters at all. They provide fresh hot water which is purer in all senses.

Safety

Earlier people did not use the water heater at all because it did not allow for safety. The heater was to be kept on at all times, which not only consumed more power but also proved for risk of safety hazards of overheating or explosion. With new tankless units, the water heater is switched on only when needed and not otherwise. It is shut after the use, and that makes this option a lot safer and takes away the risks posed by the traditional water heaters.

Environment-Friendly

The new tankless water heaters are more energy-saving and hence cause a lesser impact on the environment as compared to their traditional counterparts. They don’t need to be on throughout the process; the water is used as and when required without having to store and ruin the water quality or waste it. All these options make the tankless water heaters a way better choice. Electricity is saved and that in turn helps to preserve the perishable resources.

More Heat Settings

The new and improved tankless water heaters which have way more options for our convenience than the older ones which allowed the water to be only in one temperature. The weather is not always the same, and similarly, our demands of hot water vary too. While some like their water scathing hot, some are good with lukewarm water.
