Buying A New Water Heater? Things To Consider!

Water heaters are essential for every modern household. They are absolutely indispensable in winters as well as for any hot water needs like washing clothes or doing the dishes. For someone planning to buy a water heater, it’s very easy to get confused with all the options and varieties available in the market. Although choosing the right water heater for you mainly boils down to the purpose, space constraints and of course, your budget! Here are the important factors and features to consider before finalizing on the heater.

You will have to decide whether you want a water heater with a storage tank and one that heats water instantly. Storage water heaters tend to be a bit expensive but generally they are more durable and require minimum maintenance. Instant water heaters, on the other hand, heat only as much water as you need and when you need it. These heaters operate with least loss of heat and are often cheaper to operate than storage heaters.

The right size of your water heater will be dependent on how much hot water is used in the household. For a household with only 2-3 members, an instant water heater will suffice. For a medium-sized household, typically of 4-5 persons, a combination of instant water heaters and storage will be preferred. For a large household of 5 persons and above, multiple instant water heaters is an option or again a combination of heaters, depending on the usage of each member can be installed.

Electric water heaters come with energy-efficiency star rating labels. The more the stars, the more efficient the water heater is, the highest being a 5-star rating. Instant water heaters are generally much more energy-efficient than the traditional water heaters. These heaters use energy when it’s necessary. When the water cools off, the heating element is turned on and it heats up the water again. Installing an energy-efficient water heater means saving money on monthly electricity bills. So, before buying a water heater, choose one with a higher star rating.

Choosing the right water heater also involves keeping the space constraints in mind. If your installation area is spacious then you can choose a storage water heater since they are bulky in size and may take up a good amount of space. If you have space crunch, however, an instant water heater will be apt since they are compact in size and take up lesser space than ones with tanks.


How Many Years is a Water Heater Good For?

Your water heater is one of those everyday appliances that you probably don’t think about very often, but when it stops working, everything in the house grinds to a screeching halt. From morning showers to hard-to-clean dishes, losing hot water can disrupt several daily tasks and put everyone on edge. Sometimes the problem is relatively minor and easy to fix, a simple thermostat or heating element gone bad. But water heaters see a lot of use and sooner or later, they’re going to need to be replaced.

So How Many Years DOES a Water Heater Last?

This seemingly straightforward question is not as easy to answer as it appears. A typical hot water heater usually has a five or six year warranty, regardless of whether it’s gas or electric. However, there are more expensive units available with longer warranties, often up to ten years. While less common, there are also fiberglass units with lifetime warranties and stainless steel units that can last many years longer than a standard unit.

So all things being equal, you should expect a brand new water heater to last at least until the end of the warranty without any trouble. After that point, things get a little less certain. The average lifespan of a typical water heater being sold today is usually around 10 to 13 years, depending upon a range of factors.

Why Do Water Heaters Go Bad?

In an overwhelming number of cases, water heaters fail due to tank corrosion. Water heater tanks are made of metal and lined with a very thin coating of glass on the interior to guard against corrosion. However, the constant pressure fluctuations within the tank, caused by the expansion of heated water, will eventually compromise this thin coating and allow water to come into contact with the metal lining.

Once the tank begins to rust, failure is only a matter of time. There is no magic treatment to reverse corrosion inside a hot water heater. Within a few years, the metal will deteriorate to the point that a leak forms. When your unit starts to leak, it’s time to look into having it replaced. If your hot water heater is in the attic of the home, be sure to check in on it from time to time to make sure there’s no evidence of leaking. Replacing a water heater is a hassle enough; you don’t want to add expensive water damage to the mix.


Storage or instantaneous water heater?

Comparison between electronic instantaneous water heaters and hot water tanks (or conventional hydraulic instantaneous water heaters)

The direct comparison between electronic instantaneous water heaters and other decentralised systems (e.g. hot water storage tanks or conventional hydraulic instantaneous water heaters) shows that instantaneous water heaters have many advantages

Instantaneous water heaters are particularly efficient because they only heat the water when needed.

Storage heaters, on the other hand, store a certain amount of hot water and keep it at the set temperature at all times.

Instantaneous water heaters do not consume standby energy.

Hot water storage heaters consume standby power every day, regardless of whether water is drawn or not.

Instantaneous water heaters are significantly smaller than storage heaters, which means that they can also be used very well on small hand-wash basins. When compact instantaneous water heaters are used in the kitchen, the valuable space in the base cabinet can be used for other useful things, e.g. waste separation systems.

This is usually not possible with storage units, as they take up all the available space under the sink on their own.

Instantaneous water heaters can provide unlimited hot water.

When the amount of water stored in a tank has been withdrawn, new cold water must be heated, which can take an hour or even longer, depending on the performance and capacity of the unit.

Thanks to intelligent control and innovative technology, the most powerful electric comfort instantaneous water heaters provide a high level of hot water comfort in showers and bathrooms.

Large hot water heaters, on the other hand, do not offer modern options such as touch display or radio remote control, which correspond to the current state of the art for E-comfort instantaneous water heaters.


things to remember about water heaters

Your water heater will not last forever

Generally, you will get 7 to 10 years of performance for a water heater with a tank. But some lucky owners have water heaters that are more than 15 years old and some unfortunate homeowners have water heaters that die in two years. A good warranty for a water heater will guarantee replacement in the first couple of years.

You can keep your water heater in good condition

The No. 1 way to extend the lifespan for a water heater is flushing the scale out of your unit once a year. That process will remove sediment collecting at the bottom of the tank that could cause corrosion in your water heater. But if you haven’t drained an aging water heater for several years, forget about trying it in an older unit. The sediment may have turned into a solid rock in the tank, and the draining process may even damage your water heater

Installing a water softener can slow down the buildup of sediment in your water heater

Another issue: Sometimes your hot water starts to smell bad. That means you have to replace the anode rod in the water heater, a device that corrodes over time. The metal rod is designed to deteriorate in order to protect other metal parts in the tank. You can also call a plumber to do this job.

In buying or installing a water heater — if you have a choice — pick a gas unit

Gas will be more efficient and cost less than heating water with electricity

If you’re replacing a water heater, think about a tankless unit

Since they came out about 10 years ago, tankless water heaters – gas and electric — have become very popular. Some people call them “instant” heaters, but that’s not really true.


Things You Need to Know About Buying a Water Heater Filter

A water heater is an appliance that produces a continual supply of hot water at a preset temperature. They may also be called hot water heaters, hot water tanks, boilers, or heat exchangers. A hot water heater can be used in domestic and industrial applications to heat potable or non-potable water.

A hot water heater may have a tank or be tankless. As their names suggest, hot water tanks store hot water, and a tankless water heater produces hot water on-demand without storing water in a tank

Hot water heaters with a tank use a reasonable amount of electricity or gas to preheat the water stored in their tanks. Such water heaters also use a rather large amount of energy to keep that water warm until it is used.

Tankless water heaters are more environmentally friendly because they use a lot less energy than hot water heaters with a tank. Tankless hot water heaters heat water when you need it (on-demand). Essentially, when you turn on the hot side of your faucet or plumbing fixture, the tankless water heater goes to work delivering hot water. If you switch to a tankless water heater you can save 21% and 43% on your water heating costs for the year.

A water heater filter system is a MUST for both tankless water heaters and water heaters with a tank.

A water heater filter protects your water heater. Water heater units can become easily damaged by the sediment in the water supply, so a water heater filter provides protection against sediment, scale, and hard water
