Why Singaporeans Choose To Install Storage Water Heaters




Shared Bathrooms

Homeowners may ask if they should either install a storage or an instant water heater. However, the obvious answer to that is to opt for a storage water heater installation. It will reduce the initial investment in multiple heaters for each bathroom, and the family can use just a single large storage heater to supply hot water to different bathrooms. 

Compact Bathroom

The top 3 best-selling water heater brands and its products are available in various sizes, designs, and can be installed on the ceiling or beams of a compact bathroom. This flexibility in size and installation options make the storage heaters ideal for small bathrooms.

Bathroom Décor

Storage water heaters are available in different smaller sizes that can easily be integrated with the existing bathroom décor. In this way, the homeowner does not have to invest money to conceal it after installation. 

Immediate Hot Water Access

Though tankless or instant water heaters are considered more efficient, they will produce hot water only when switched on. In contrast, even if there is no electric supply to the house, the user can get hot water for some time with a storage water heater. 

After knowing why Singaporeans choose to install storage water heaters, be sure to learn about the things to note during a water heater installation.

Things to Consider Before Any Storage Water Heater Installation



In comparison to other electrical appliances you may have in your home, the quality of the storage water heater you are opting to install or buy is one of the things you should consider for a low-quality water heater that may malfunction and cause water heater issues

Safety Features

Installation Area

The storage water heater with the right size has to be chosen depending on the size of the bathroom where you want to install your water heater. For smaller bathrooms, a compact water heater is preferred. 


Tank and Heating Element

Replacing your water heater to a storage water heater comes with a storage tank that may always be full at a higher temperature. That is why it is important to consider the material of the tank, which should be made from a corrosion-resistant material.

Factors Affecting Storage Water Heater Installation Cost

How To Prepare for Storage Water Heater Installation

Make sure it fits in the location

You should ensure enough space in the bathroom to properly make the electric and plumbing connections to the water heater without any obstruction. Storage water heaters are usually installed above the false ceiling because of their bulky size. 

Check water supply route

The water that will pass through the showerhead, as well as the tap, will depend on what type of water heater you use.  For a storage water heater, the water in the pipes will be stored in the tank. 


The water heater you will install should be based on the amount of water you need. Keep in mind that you should consider the number of people who use hot water. For big families or for commercial spaces that use hot water the most, it is advisable to install a 40 Liters tank capacity like the Rheem EHG 40.

Common Issues That Occur During Storage Water Heater Installation

  • Buying the Wrong Water Heater Size

The size of the water heater depends on the capacity of the heater, and the amount of water it will heat. If a larger capacity heater is selected for a small family, more energy will be required to heat a larger volume of water, and some of the hot water may not be needed.

  • Wrong location or placement of water heater tank

One of the reasons behind a leaking water heater is due to improper water heater placement. An improper water heater placement can damage the siding, ruin flooring, wreck personal belongings, and more.

Besides being familiar with the common issues that occur during storage water heater installation, you should know how to choose the best water heater installer to ensure that your water heater is installed properly.

Choosing The Best Water Heater Installer




Company’s Reputation

One of the points to note during water heater installation is choosing a well-established company. For example, a company with more than ten or twenty years of experience, can be more trusted for the installation and to attend to your water heater issues and maintenance in the future.

Company’s Experience

If the staff are well trained and experienced, they are more likely to be aware of the different types of storage water heaters available. Aside from being aware of the best practices, they exactly know when you should replace your water heater.

Whether Company Is Licensed and Insured

An important fact about water heater installation is that it should be done by professionals because of its complexity. Licensed plumbers also know the significance of installing energy efficient water heaters and you can rely on them to install one into your bathrooms.

Company’s Tools and Technology

Having the latest equipment for quick installing and replacing is one of the reasons to hire a professional to install your water heaters. The plumbers are also well trained in the most suitable techniques, using the best testing equipment to avoid the causing of water heater failure due to improper installation.

Company’s Certifications

In addition to having licensed plumbers, the company should have acquired certifications from relevant bodies which show that they have the best systems in place. In this way, they can ensure that all the clients get the same quality of service.

Company’s Servicing Costs

Before you contact a water heater servicing company, it is recommended to get a quote from at least three reputed companies. This will help the property owner get information about the market rates for the installation work, terms and conditions, and the time taken.

If you are thinking of having a storage water heater installed in your home, keep in mind the things to consider before any storage water heater installation. You should also study the factors affecting storage water heater installation cost and the best storage water heater brands. To prevent any form of damage, you should also know how to prepare for storage water heater installation. Knowing the common issues that occur during storage water heater installation is equally vital. To ensure that your storage water heater is properly installed, take note of how to choose the best water heater installer as well.

Mr Kumar was very proactive and genuine in his profession. Others may just change the water heater tank n will leave but mr kumar informed that the flexible host is almost broken n it is dangerous. So he helped to change the flexible host to a stainless steel. He explained very patiently whenever i ask him questions. He was very warm n very helpful. He waited to make sure whether there is any leakage. I am very impressed for he knows what he is doing and also very patient and warm. Very good indeed. 👍
