Tankless water heater vs tank water heater

Tankless water heater is really helpful?

Answer 1:

A ecosmart eco 27 (Links to an external site.) tankless water heater is more suitable for homes where the hot water consumption of the water heater would be less than 120 liters per day. In such a scenario, installing a tankless water heater would save 15-20% electricity over a traditional storage tank type water geyser. For higher consumption requirements, a storage tank type water heater is a good choice.

Now, having purchased a water geyser for my home only a few hours ago, after extensive research and analysis over a period of eleven days, I would say that when considering purchasing a water geyser, there are particularly two areas that one must pay for. to the utmost attention to. They are:-

Water geyser storage tank capacity

The number of family members to make use of the water geyser dictates the storage tank capacity that one should opt for a water geyser. As a rule of thumb: -
If more than five members are going to use the water geyser, a 25 liter tank capacity water geyser would be a decent option.
When four or five family members must use the hot water obtained from the water geyser, a water geyser that has at least 10 liters of storage capacity would be required, preferably 15 liters.
For a family of two or three, it would be advisable to opt for at least a 6-liter water heater.
For individual use, one would have their needs covered by a water geyser that has a tank capacity of 3 liters.

Material used in the manufacture of the heating element.
The heating element is one of the most crucial aspects of a water geyser, as it is the component responsible for raising the temperature of the water. The heating element accounts for almost 40 percent of the total cost of the water geyser and is therefore a perfect opportunity for some manufacturers to cut costs and increase the profit margin. These manufacturers use ceramic-lined heating elements in the water geysers they manufacture. This heating element is relatively cheaper to produce, which makes it easier for the manufacturer to attract customers by citing low prices for the product. However, in reality, ceramic-lined heating elements are highly non-durable and prone to rapid corrosion. Such water geysers require heating element replacement every season or two. Rather, one must ensure that the water geyser that is chosen has a glass / copper lined heating element.
Okay, I have a confession to make ...

The information I have mentioned above is not my find, but someone else's. I have been looking to purchase a water geyser for my home for the past nine days and searched Quora and Google for an answer that might help me make a purchasing decision.

As a potential buyer, it was very essential for me to get answers to questions like:

What should I look for when buying a water heater?
What type of heating element should I consider purchasing my water heater with?

Ceramic coated or glass lined. What are the pros and cons of each.
With what water storage tank capacity should I consider purchasing a water geyser, considering that I, my younger brother and my parents must use the bathroom where the

water geyser will be installed?

Among the many water geysers available on the market made by various brands, how can I decide on a product that meets the requirements of my family?
Unfortunately, most of the answers are mainly focused on the product and the features on offer. (No offense). He had almost given up all hope of finding a satisfactory answer, but then ...

Then this morning I came across a post that answered most of my inquiries. I read about the following in the post: -

How does a water geyser work?What are some of the factors one should consider when deciding on a water geyser for their home?
Which Energy Star rating should I consider purchasing a water geyser, which strikes a balance between lower power consumption and lower initial product cost?
How some brands mislead their customers and try to maximize their own profits by making poorly constructed products that are highly ineffective in their water heating operation and subject to requiring repairs / replacements every season.

What are some of the best products available on the market that not only offer excellent heating capacity?

heating systems, but also provide long-term reliable service, providing good value for money.

So today, that is, December 6, 2019, at 12:57 p.m., I placed the order for my water geyser, taking into account the insights gleaned from the post.

Those hoping to purchase a water purifier, thankfully, I have bookmarked the link to that post for future reference, if needed. I can post the link here, you might find it helpful.

Best of luck. Beware.

Answer 2:

Most installers / vendors will push for tanks, but they're not necessarily the best option. Why are they pushing it? Because they earn more $. I often wonder how many of them would buy one if they had to pay the same for the one they are selling it for.

I know people who changed tankless tank where some love it and some hate it.

There are pros and cons to both ... but I think it really comes down to the person and their situation. It's pretty annoying to hear people recommend tank-over-tank because it's not a one-size-fits-all decision.

If 2 people live in a small house and use minimal water and can't afford the $ 3k + price tag (with installation) I'd say ... maybe. Eventually, they'd get their money back after 10+ years, as tank heaters always get hot in comparison, and tankless ones will save a few square feet of living space. In terms of constant hot water, it's probably not relevant for 2 people as the 40 gallon tank is more than enough. This also represents 2 natural gas tank heaters ($ 900 each installed) as they have half the life of a tankless tank.

If there are more than 8 people in a house and hot water flows constantly, it would still be without a tank. You're not really saving much on efficiency (as the coil is constantly running anyway to supply the constant demand for water) BUT, the hot water won't be depleted like a tank would.

Imo, if you do it to save money and you live on an average of 4-5 people living without a gas tank, it won't cost less (maybe more) than a tank in the long run. Plus, you're offering a lot more money when it could be used for other things. Personally, I wouldn't run out of a tank in the case because in my area the average home consumes $ 12 / month worth of natural gas with an average 40 gallon tank. 30% of this is $ 3.60 / month in energy savings. A tankless tank will average $ 1800 more (installed) than a tank. If the tankless tank lasts 20 years, it would have needed 2 tank heaters with an average lifespan of 10 years each. The average 40 gallon tank is $ 900 installed. So I spent $ 900 more for a tankless tank in 20 years. However, I saved $ 3.60 / month on energy in those 20 years ... which equates to almost 21 years before breaking even. So, actually ... you're losing money without a tank. Also, based on personal experience, you are more likely (imo) to need repairs on a tankless tank than a tank in that lifetime. Why? If you really see the inside of a tankless water heater compared to its counterpart, it has more organs than a tank. More organs = more to go wrong.

To increase cost and conserve the environment, the average tank wastes more water, as the coils take longer to heat the water before you can use it. Meanwhile you are flushing good water and adding $ down the drain. Now you can get tankless with shock absorbers, which give you hot water at the same rate as a tank and avoid wasting water ... but be prepared to spend an extra $ 400. Again, losing more money. Also, truth be told, the more hot water you have ... the more you use.

People really need to do their research before they are convinced of what others are saying. I used to assume that the tankless option was the best option because of what common sources would say. Until I did my own research, I was surprised by the amount of widespread misinformation.

In the average home, unless it is imperative to gain a little extra space, and / or not to run out of hot water while using it ... Tankless tanks seem to me to be a fad.
