Why Choose an Instant Water Electric Boiler: Benefits and Applications

Table of Contents


Water is heated for daily use, such as showering, cleaning, or laundering. Have you ever considered how hot water finds its way to your tap? There are a few types of water heaters, and what you choose could significantly impact your energy bills, the space in your home, and even your safety. Today’s newest and most influential system is a tankless water heater, also known as an instant water electric boiler.

Conventional water heaters store a big tank of water, keeping it hot, but instant water boilers work by heating water only when needed. This way, you enjoy hot water service only during your time of need, without waiting for any tank to fill up or, instead, without running out of hot water.

In this blog, we will see some of the reasons why instant water electric boilers are so beneficial, and the Yorkmate YM-C16 might fall into your scheme of things.

What is an Instant Water Electric Boiler and How Does It Work?

An instant water electric boiler does is that it warms water while it passes through the device. The working principle distinguishes the tankless water heater from traditional storage tank water heaters: hot water is afforded on the go, not stored for use.

When hot water is requested at a tap, cold water enters a pipe into the water heater. A gas burner or an electric element warms the water inside the unit. The result is that you have a ready supply of hot water at virtually every fixture simultaneously, and the waiting time for a tank first to heat a quantity of water is eliminated. It is also why it is commonly called “on-demand” water heating.

Here’s a step-by-step look at how an instant water electric boiler works:

Activation: The heater is energised, and water is heated when a hot-water tap is opened.

Heating Process: Cold water flows through it and is rapidly heated by the action of a gas burner, electric element, or some other heat source.

Delivery: This hot water then flows through to your tap or appliance, producing uninterrupted hot water until you stop the flow by closing the water at the tap.

Comparison with Traditional Water Heaters

The heaters work by keeping a massive volume of water in a tank, heating it, and maintaining the heat perpetually. This manner of heating can result in substantial energy losses known as standby heat loss, as the heater keeps reheating the water to maintain a given temperature setting on the unit.

On the other hand, an instant water electric boiler heats water only when needed, meaning there are no standing heat losses, and the energy savings can be immense. It is one of the primary efficiencies that have made most people change to on-demand water heaters.

Constant Supply of Hot Water

One of the benefits of an instant water electric boiler is a continuous hot water supply. Conventionally used tanks can create a lack of hot water if a lot is used, such as taking back-to-back showers with a running bath and the clothes washer going. With a tankless system, as long as demand doesn’t exceed capacity, there remains a never-ending hot water supply.

Energy Efficiency

Instant water electric boilers will be more energy efficient than conventional tank water heaters. According to the Department of Energy, under normal circumstances, a tankless water heater is 24%-34% more energy efficient than traditional storage tank water heaters for a household with a daily demand of 41 gallons or less of hot water.

For those who require a lot more hot water, around 86 gallons per day, it can be 8% to 14% more energy efficient.

Benefits of Using an Instant Water Electric Boiler

Energy Efficiency

Instantaneous electric water boilers present one of the best forms of efficiency: by nature, they allow water to be heated precisely when needed, eliminating the energy losses of having large masses of water hot, sitting in reserve indefinitely. In this regard, on-demand heaters are far more energy efficient than tank water heaters.

The U.S. Department of Energy estimates that between 34% of energy can be saved by tankless water heaters for homes that use less than 41 gallons of hot water daily.

Space Saving

The tankless water heaters are by far the most compact size compared to the traditional tank water heaters. They do not require water storage, so that they can be mounted on walls or placed in small spaces.

Also, their compact size makes them an excellent choice for installation in places with less space. The compact size also means they can be installed close to the point where hot water is required, hence lessening the wait time for hot water to reach the tap.

Endless Hot Water

A tankless water heater will never leave you worried about running out of hot water. It will continuously supply hot water, provided its capacity is within the maximum. It is handy for large families or homes with high hot water demand. You can enjoy those long showers, run that dishwasher, or do laundry without fearing the aftereffects of using all hot water.


Tankless water heaters tend to last longer than conventional heating units with tanks. While a standard tank heater may be helpful for up to 10-15 years, a tankless style may last up to 20 years or more if properly maintained. This long lifespan makes tankless water heaters a good investment in the long run.

Safety and Clean Water

Tankless water heaters offer improved security in different ways. They have temperate precision control, implying that scalding is very unlikely with this kind of system.

Also, because they do not store water, there is far less opportunity for bacterial growth than with most conventional tank-type heaters. Hot water from a tankless system will be much cleaner and safer for your home.

Comparing Instant Electric Water Boilers to Traditional Water Heaters

Operational Differences

Conventional water heaters store large amounts of water heated to a constant temperature inside the tank. It makes the heater go on and off constantly to adjust the temperature, leading to energy losses referred to as “standby heat” losses.

On the other hand, an instant water electric boiler heats water only when needed. It thus eliminates the need for standby heat losses, making it very energy-wise. They also allow for an endless supply of hot water, as the capacity of the tank does not limit them.

Cost Comparison

Although an electric instant water heater seems more expensive than a traditional one, the running cost of electricity bills will save you lots of money in the long run. On the other hand, tankless water heaters come with low lifetime costs and a better lifespan, offering significant savings over a period.

Maintenance and Durability

Both need maintenance, but only sometimes through tankless heaters. Traditional storage tank water heaters must be periodically drained and cleaned out; otherwise, sediment formation will reduce efficiency and lifespan. Tankless water heaters are less susceptible to these problems and can last with proper care over a much extended period.

Environmental Impact

Tankless water heaters are generally treated as green compared to traditional tank heaters. Due to their efficiency, they consume less energy, thereby reducing carbon output. Additionally, due to their longer lifespan, the heaters leak much less waste to the landfill than the traditional heaters that are disposed of and replaced more often.

Applications and Settings for Instant Water Electric Boilers

Instant electric water boilers are versatile, and their use can be diversified in several applications, not limited to.


Electric water heaters are widely used to supply hot water for bathroom equipment, kitchen sinks, dishwashers, and washing machines in residential buildings. Compact, it only takes up a small area for installation and is very suitable for apartments or tiny houses.


An instant electric water boiler might be the best solution for businesses with high demand for hot water, like restaurants, hotels, and gymnasiums. It allows for a continuous supply of hot water in significant quantities without any possibility of it running out.

Remote Locations

Instantaneous electric water boilers are ideal for remote or specialised applications, such as bathrooms, hot tubs, or outdoor kitchens. Due to their compact sizes and instantaneous heating, they are the best alternative to those areas where traditional water heaters cannot be applied.

Features to Look for When Choosing an Instant Electric Water Boiler

In choosing instant electric water heaters, it is good to consider the following features:

Flow Rate

The flow rate is measured in gallons per minute (GPM) and describes the volume of hot water the unit provides. This amount should support your household’s high demand for hot water so that you are supplied.

Energy Efficiency

Search for units that have high energy efficiency ratings and are Energy Star certified. The higher the efficiency, the lower the energy bills and the smaller the environmental footprint.

Size and Installation Requirements

Consider the size of the unit and how you need to install it. Ensure you have sufficient space to install the unit and that your property’s electrical or gas systems can accommodate it. A few models may even need extra entitlements, such as electric upgrades for electrical units or venting for gas models.
