Your Guide to Choosing the Right Water Heater

Your water heater can be a vital part of your home and picking the right water heater in Malaysia will ensure that you not only have a steady supply of water but that it also is produced with a minimal amount of energy, saving you money and protecting the environment.

Below, we’ll examine the different types of shower heaters plus examine the advantages and disadvantages of each type so that you can make a smart decision on what to choose for your home.

Storage Water Heaters

Conventional storage-tank water heaters have been around for quite a while and are still a rather popular option used in Malaysian homes. These types of water heaters can hold a certain amount of water ranging from 75 to 300 liters in a storage tank and heat it up using fuel or electricity. It will then release water from the top of the storage tank when you turn on the faucet or fixture.

Pros of Tank Heaters

Simple technology – Storage water heaters/tank water heaters feature a simple concept with a heating element or burner that heats the water in the tank and maintains it at the right temperature with the help of a thermostat. The basic principle is pretty simplistic itself.

Variety of fuels – Storage heaters or tank water heaters are readily available in models designed for use with electricity or gas (LP or natural gas).

Low upfront costs – Storage shower heaters are abundant and relatively inexpensive. They’re an excellent choice if you don’t want to fork up a high amount of money upfront for your water heater.

Cons of Tank Water Heaters

Less efficient – A storage water heater needs to maintain the water temperature in the tank. This means that it will need to keep consuming energy throughout the day even when it’s not being used. Not only will the standby heat loss cause inefficiency, but it will also drain resources. However, several models do come with timers and a programmable thermostat to offset this issue.

Higher Operating Cost – As mentioned earlier, the standby heat loss will cause you to use more energy to operate a storage water heater. This translates to more electricity usage and higher monthly energy bills.

Tankless Heaters

Tankless water heaters are also known as on-demand shower heaters that will provide hot water only when you need it. This means that they eliminate one of the biggest drawbacks of storage water heaters: the energy cost of standby operation. Instant water heaters use electric heating elements such as electrical coils to heat up the water as it travels through a pipe in the unit.

This type of water heater is also more compact and takes up less space compared to the tanked version.

Pros of Tankless Water Heaters

Improved Energy Efficiency – Since the water heater does not heat up water continually throughout the day, these instant water heaters have the potential to help you save a lot of money in terms of energy use.

Easy Installation – Small tankless water heaters can be installed almost anywhere in your home, so they make an excellent hot water solution without needing to resize your home’s entire water heater system.

Space Saving – Without the bulky tank, instant water heaters require very little space, making them an ideal choice for use in small homes or apartments.


Inconsistent water temperature – You need to make sure to size the tankless shower heater properly or you may just end up outstripping capacity when hot water demand is high in your home. In some cases, it may even be necessary to install multiple water heaters in different locations throughout the home.

Higher Initial Cost – Efficiency also comes at a cost since such models have a higher purchase cost and often require more labor cost for installation compared to conventional storage water heaters.

Factors to Consider when Shopping for the Best Water Heater in Malaysia

Pump or No Pump?

The first step when choosing a water heater is to look at the features you need. If your house often experiences low water pressure, then it’s worth looking for a water heater with a built-in AC booster pump to boost the water flow. However, do note that some pumps may be noisy and could possibly disrupt the relaxing feeling of a shower. In that case, you can look for a built-in silent pump that will maintain relatively acceptable noise levels.

AC or DC Motor?

If you’re going for a model with a pump, you’ll also need to look at choosing one with either a DC or AC motor. DC motors are typically more expensive but they ensure silent operation with a maximum noise level below 35dB. They’re also usually more durable and energy-efficient too.

Water heaters with AC motors on the other hand are more cost-friendly initially. They’re often available in cheaper models but the disadvantage of having them is a shorter lifespan and high noise levels when using it.

What’s your Budget?

There are many shower heater units that come with all kinds of sleek and innovative designs. But those with nice designs usually come with a hefty price tag. So if you’re on a tight budget, the aesthetics should not be a priority and instead focus on the functions you need.

How much Space do you Have?

Always measure the space or wall you plan to install your new heater. The amount of space you have will help narrow down your searches. If you’re unsure, you can always ask a contractor from the store to give you the measurements you need for the model you desire.
