The Advantages of a Tankless Water Heater 

| Monday August 15, 2022

What most people didn’t know is that they might be wasting a substantial amount of energy, water, and money with a traditional, aged water heater. Some Malaysian homes are still using storage-type water heater, which features these big, bulky tanks. 

These storage heaters are much larger and heavier than tankless water heaters and they are usually mounted away on the ceiling or in a hidden corner. For heaters like these, heat will be depleted if many people are using it at once.

Apart from that, storage heaters face the possibility of leakages as well, which may end up damaging your ceiling and causing slippery hazards.


A Quick Intro to Tankless Water Heater

Tankless water heaters are basically normal water heaters, but more intelligent. 

They are also known as on-demand or instant water heaters. Be it operating on gas or electric, tankless heaters only heat up water when you need it to. It will have a clear digital display of the temperature, and it is fully adjustable.

Engineered for precision, tankless water heaters can produce hot water at a consistent temperature, so you won’t face any temperature ups and downs during your shower. 

Let’s take a look at the many benefits of a tankless heater.


The Benefits You Can’t Resist

Tankless electric water heaters are capable of offering continuous hot water for single point-of-use or multiple applications such as shower heads, sinks, tubs, dishwashers, and even washing machines. 

Let’s go through the benefits of having one at home.

Long Lifespan

A high-quality tankless water heater can last anywhere from 15 to 20 years with proper maintenance and operation. Even if there’s a repair needed, parts are easily replaceable. In contrast, traditional water heaters will have to be replaced every 7 to 10 years. 

Safety Aspects

As time goes by, traditional water heaters pose safety and health risks due to corrosion, leaks and old water that could be contaminated with rust. 

A tankless water heater, on the other hand, is relatively safe from corrosion or bursting. Furthermore, it operates entirely on-demand, which prevents water from reaching scalding temperatures.

Energy Efficient

Tankless electric water heaters can achieve a thermal efficiency rating of up to 99.8%! This means 99% of the electricity that goes into the warming process comes out as heat, leaving a smaller carbon footprint behind.

This is estimated to be 24-34% more energy-efficient than regular water heaters for a household.


Being energy efficient makes a tankless water heater energy and water-saving. This way, you’ll spend far less money on your monthly utility bills.

With the cost of energy on the rise, having a tankless water heater is definitely a great investment in the long run.

Space Saving

Due to their significantly smaller size, tankless water heaters won’t take up much space and they can be mounted in various areas around your home (both outdoor and indoor).

Easy Installation

If you’re thinking of installing one, know that the process generally takes a little more than one-hour only.


Before You Buy

Picking the right tankless water heater depends on what you wish to use it for, as it comes in different sizes, functions, and specific features. 

A heater that’s too small won’t adequately meet your home’s hot-water needs while having a heater that’s too large is an unnecessary cost.

To determine your hot-water needs, list the total number of appliances you will be using simultaneously during peak demand. Then, consult a professional to get the best recommendations for your household.
