Understanding the Difference Between Storage And Instant Water Heaters

Understanding the Difference Between Storage And Instant Water Heaters

Featured Product: FZ-SH3030 Storage Water Heater 30L

Picture this: It’s early in the morning, and you’re preparing for a rejuvenating shower to kickstart your day. You confidently turn on the tap, anticipating a steady stream of warm water. However, to your dismay, a sudden burst of chilly water catches you off guard. Cold showers? Certainly not your preferred way to start the day, is it?

For new homeowners and even long-time homeowners, selecting the ideal water heater can be a challenging task. With various types available, making an educated choice is paramount. 

In today’s market, the primary options often boil down to two categories: instant water heaters (also known as a tankless water heater) and storage water heaters. But what distinguishes them, and which one best suits your requirements?

What is a Tankless Water Heater?

Also known as point-of-use water heaters, instant water heaters provide hot water on demand. They work by heating the water right as it passes through an exchanger. Rather than storing and reheating water in a large tank, these electrical appliances heat the water precisely when you turn on the faucet. They are also compact, space-saving appliances installed close to the point of use, such as bathroom showers.

So, here’s the key distinction worth noting: rather than storing and reheating water in a large tank, instant water heaters heat the water precisely when you turn on the faucet. They are also compact, space-saving appliances installed close to the point of use, such as bathroom showers.

Moreover, given its absence of a bulky water tank and the proximity to outlets, you don’t have to wait for hot water or waste litres of cold water while it travels through pipes. Also, since they are designed to deliver hot water almost instantaneously, they not only eliminate the need for continuous heating and reheating but also help save energy and money as a result — truly highly energy-efficient appliances.

How Differently Does a Storage Water Heater Work?

A storage water heater, also known as a tank-type water heater, is a truly reliable workhorse in the world of water heating. 

Unlike their instant counterparts, which heat water on demand, storage water heaters operate differently.

At the heart of a storage water heater is a well-insulated tank that holds a specific volume of water, typically ranging from 15 to 30 litres. Heating elements within the heater heat the water inside the tank, maintaining it at a constant temperature. This means that once the unit is switched on, it begins heating the water and keeps it at the desired temperature for use throughout the day, providing you with a continuous supply of hot water. 

However, there is a trade-off when it comes to energy efficiency. Because storage water heaters have to work to constantly maintain the water temperature, they may consume more energy compared to their tankless counterparts. But you can always switch off the heater when hot water is not needed to mitigate energy usage.

So, Which is Better?

Now for the million-dollar question: tankless heater vs. storage heater — which one is the right fit for your home? 

So, Which is Better: Storage Heater or Instant Water Heater?

There’s no definitive answer, as it all depends on your specific needs and preferences. Both types have unique advantages and limitations, so your choice should align with your requirements and usage patterns. 

Consider the following key differences to make an informed decision tailored to your needs:

1. Waiting Time

One of the key distinctions between tankless water heaters and storage water heaters lies in the time they take to heat up your water supply. 

Instant water heaters live up to their name, swiftly heating water as it flows through their compact heating chambers. This means there’s minimal waiting time for your water to reach the desired temperature.

On the other hand, storage water heaters typically take about 30 minutes on average. However, modern and efficient models, such as FUJIOH’s premium range of storage water heaters, such as the FZ-SH3030, featuring the Incoloy® 840 Heating Element, are designed to significantly reduce this waiting time.

Verdict: If you prefer hot water on demand without any delay, tankless heaters are the clear winners in this category. Nevertheless, it’s worth noting that storage water heaters, especially high-quality ones, have come a long way in reducing heating time and making the wait more bearable.

2. Temperature Consistency

Tankless heaters heat water on demand, which can lead to fluctuations in water temperature, particularly during rainy seasons when incoming water is cooler. In contrast, storage water heaters offer consistent temperature control. This is because they draw water from a pre-heated tank, ensuring the water temperature remains stable regardless of external factors.

Verdict: When it comes to temperature consistency, storage water heaters can reliably provide a steady supply of hot water. However, it’s worth noting that FUJIOH offers instant heaters that put you in control of your shower temperature. With just a simple turn of the knob, you can enjoy a comfortable shower experience, regardless of the unpredictable climate fluctuations.

3. Water Pressure

Water Pressure

Water pressure matters when it comes to your shower experience, and your choice of water heater can impact it. However, it’s important to note that the type of shower headshowerhead you use and where you live also affect pressure. 

Tankless water heaters mayheaters, may sometimes reduce water pressure to heat the water quickly. It is also influenced by the household water supply — say, for example, if someone turns on the tap in the kitchen, the pressure of your shower might be affected. 

On the other hand, storage water heaters heat up the water within the tank without affecting the main inlet’s flow, providing more consistent water pressure. 

Verdict:  If you want to maintain your water pressure, storage water heaters help provide a consistently strong flow that’s perfect for massage jets and luxurious rain showers. However, FUJIOH’s tankless heaters come with a DC pump option that increases the water pressure, offering an alternative solution for those seeking a similar shower experience.

4. Water Capacity 

Tankless water heaters provide an essentially unlimited supply of hot water. They heat the water on demand, so as long as you have a water supply, you can enjoy hot water for as long as you need.

On the flip side, storage water heaters have a limit to their capacity, which is determined by the size of the tank. Once the tank is emptied, you may need to wait for it to heat up more water before you can continue using hot water.

Verdict: The right choice of heater for your abode largely depends on your household’s hot water needs and preferences. For uninterrupted hot water, tankless heaters are the go-to option. However, if you require a substantial and consistent supply of hot water, especially for larger households, a storage water heater with a bigger tank capacity might be the better choice. 

5. Ease of Installation

Tankless water heaters are relatively straightforward to install. They are designed to connect to a single outlet at a time, making the installation process relatively simple. But then again, to ensure the safety of your instant water heater, it is always advisable to engage in professional help for proper installation.

Storage water heaters, on the other hand, are a bit more complex when it comes to installation. While a single unit can typically serve multiple bathrooms, the challenge lies in the installation itself. To ensure hot water reaches every usage point, your interior designer or contractor will need to put in extra effort to lay the necessary water piping. This process can be more time-consuming and may require professional assistance.

Verdict: If you prioritise easy installation, especially for single-outlet setups, tankless water heaters offer simplicity and convenience. However, if you have a larger household with multiple bathrooms, a storage water heater can serve them all, although it may require a more intricate installation process.
